Inpatient rehabilitation improves functional capacity, peripheral muscle strength and quality of life in patients with community-acquired pneumonia: a randomised trial

Contribution of small airway disease to dynamic hyperinflation in patients with chronic obstructive pulmonary disease

Lung hyperinflation is a treatable trait in chronic obstructive pulmonary disease (COPD) that can often only be detected on exertion. Air trapping in these patients results from the premature closure of the small airways. This study aimed to assess the association between small airway disease (SAD) and dynamic hyperinflation (DH) induced by the Glittre-daily life activities test (TGlittre) in COPD patients. This is a cross-sectional study in which 54 patients with COPD underwent TGlittre coupled with dynamic ventilation measurements. They also underwent the COPD Assessment Test (CAT) questionnaire, the St. George's Respiratory Questionnaire (SGRQ), spirometry, and respiratory oscillometry (RO). In the TGlittre, 30 (55.6%) participants presented DH (DH group), while 24 (44.4%) did not (NDH group). When comparing these two groups, we observed no statistical difference concerning the CAT score, SGRQ score, and spirometric parameters. Respectively, 27 (90%) and 9 (37.5%) participants in the DH and NDH groups presented changes in the RO, with the DH group showing higher values in reactance area [Ax, 24.7 (17-46) vs. 6.1 (4-9) cm H2O/L/s, p<0.0001] and resonance frequency [Fres, (8 (4.3-17.9) vs. 2.8 (2.3-4.7) Hz, p<0.0001]. DH correlated significantly with Fres (rs=-0.604, p<0.0001), Ax (rs=-0.652, p<0.0001), and several domains of the SGRQ and CAT scores. In the multivariate regression analysis, Fres and Ax explained 49% of the variability in DH. In conclusion, our results show that patients with COPD and DH have more altered RO. In these patients, the more pronounced the DH, the worse the RO parameters, the greater the symptom impact, and the more deteriorated the quality of life. Furthermore, SAD is a significant predictor of DH in this patient population.

Efficacy of early pulmonary rehabilitation in severe and critically ill COVID-19 patients: a retrospective cohort study

BACKGROUND

Respiratory sequelae, induced by lung injury, reduced muscle strength, and nutritional disturbance, are common in hospitalized patients with coronavirus disease 2019 (COVID-19). Therefore, optimal treatment is essential for reducing the mortality in severe forms of the disease and critically ill patients. Pulmonary rehabilitation (PR) has been used in many chronic respiratory diseases, but the role of early PR in severe and critically ill COVID-19 patients remains to be fully understood.

METHODS

Hospitalized severe to critically ill COVID-19 patients were recruited from Beijing Chaoyang Hospital between December 1, 2022, and June 30, 2023. In all, we recruited 272 patients, with 39 in the PR group and 233 in the control group. The PR intervention consisted of the prone position, airway clearance therapy (ACT), and resistance respiratory training (RRT). The primary outcome was the composite disease progression outcome rate, defined as death or intensive care unit (ICU) admission. Adverse events (AEs) and serious adverse events (SAEs) were recorded in the PR group. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) was used to balance confounding bias, generating weighting cohort and matched cohort.

RESULTS

The rate of the primary outcome was lower in the PR group (28.2% [11/39] in the PR group vs. 48.9% [114/233] in the control group). Significant differences were observed in both the original and weighting cohorts. Subgroup analyses showed that receiving ≥ 2 types of PR, receiving RRT, length from admission to intervention ≤ 4 days, and baseline P/F ≤ 150 mmHg were associated with lower rates of progression. Total rates of 2.6% (1/39) for AEs and 10.26% (4/39) for SAEs were reported.

CONCLUSIONS

Early pulmonary rehabilitation may prevent disease progression and reduce mortality in patients with severe COVID-19. These findings may be helpful for formulating an optimal rehabilitation strategy.

Feasibility within-subject RCT of neuromuscular electrical stimulation; an Intervention to Maintain and improve neuroMuscular function during period of Immobility (IMMI)

INTRODUCTION

Neuromuscular electrical stimulation (NMES) is a potentially effective intervention to improve outcomes after a fragility fracture, but its feasibility in this group has not been established.

METHODS

A feasibility study was conducted in two phases: 1) in the hospital only, and 2) hospital, rehabilitation centres, and participants' homes. Patients with fragility fracture were randomised to receive NMES for 6 weeks/discharge either to the right or left leg, with the other leg serving as control. Patients who had no mobility issues had contraindications to NMES and were unable to give consent were excluded. NMES was applied to quadriceps and tibialis anterior muscles for 30 min, 3 days/week. Sessions were progressed to achieve 60 min, 5-7 days/week. Feasibility outcomes included participant characteristics, recruitment rate, tolerability, and number of NMES sessions. Clinical outcomes included muscle strength, and ADL at six months.

RESULTS

Overall, 1052 patients were identified, of whom 113 (11%) were eligible, and 29 (3%) were recruited (median Clinical Frailty Score 3, median Barthel ADL score 93/100). The recruitment rate was 0.45/week in phase 1 and 0.9/week in phase 2. Fifty-three percent achieved the target of 24 NMES sessions. However, 5/29 withdrew due to intolerance of NMES. Leg muscle strength improved in both treated and untreated legs, with marginally greater improvement observed in the tibialis anterior of treated legs.

CONCLUSION

Although it would be feasible to evaluate the specific effect of NMES in fragility fracture patients in a multi-centre trial using home-based NMES, this would be possible only in a minority of mildly frail fragility fracture patients with little premorbid disability.

Psychophysiological effects of a supervised home-based resistance band exercise program in pre-frail older patients with type 2 diabetes mellitus: a randomized controlled trial

BACKGROUND

Frailty is a syndrome as with aging in the population of type 2 diabetes mellitus (T2DM) and exercise has become an essential non-pharmacological tool especially in the pre-frail stage. Notably, the form of supervised home-based exercise program has been strongly recommended in recent years. This study aimed to verify the potential effects of the supervised home-based elastic band exercise in pre-frail older T2DM patients in China.

METHODS

A total of 100 participants were included and randomly divided into intervention group (IG) (n = 50) and control group (CG) (n = 50). The CG received a routine care, while the IG received an extra home-based elastic band training under online and offline supervisions sustaining 12-weeks. The glycosylated hemoglobin (HbA1c), blood lipids, body composition, physical function, scales of Diabetes specificity quality of life scale (DSQL), Pittsburgh sleep quality index (PSQI) and short form geriatric depression scale (GDS-15) of the participants were evaluated before and after intervention.

RESULTS

The average age of the participants were 66.01 ± 4.76 with 55% male and average BMI 24.75 ± 3.51 kg/m2. The clinical characteristics of the two groups were comparable. After 12 weeks' training, muscle mass of the limbs (P < 0.05), physical function indicators including grip strength, chair stands (both P < 0.05), walking time (P < 0.01), HbA1c (P < 0.05), frailty score (P < 0.05), subjective sleep quality (P < 0.05), total DSQL scores (P < 0.01) and the depressive status (P < 0.01) improved significantly in IG when compared with CG.

CONCLUSION

Supervised home-based elastic band exercise could improve limb muscle mass, physical fitness, glucose and lipid control and quality of life in pre-frail older T2DM patients.

Effects of Chest Physiotherapy on Reducing Dyspnea and Enhancing Functional Independence and Quality of Life in Multilobar Pneumonia: A Case Report

Bronchopneumonia is characterized by inflammation of the lungs, predominantly affecting the bronchioles, whereas lobar pneumonia is a bacterial infection that leads to inflammation primarily in the alveoli and lung lobes. We present the case of a 65-year-old male patient who presented with complaints of breathlessness and cough accompanied by whitish expectoration, ultimately diagnosed with multilobar pneumonia. The patient was subsequently referred for chest physiotherapy to address these complaints. As physiotherapists, we employed a range of treatments, including early mobility, active breathing exercises, and airway clearance techniques. This case underscores the significance of chest physiotherapy for patients with multilobar pneumonia. Outcome measures included the Modified Medical Research Council dyspnea grading scale, the Functional Independence Measure score, and the Numerical Pain Rating Scale. Following the rehabilitation program, improvements were observed in all outcome measures. These findings indicate that a tailored pulmonary rehabilitation program can significantly benefit patients with pneumonia by reducing dyspnea and enhancing functional independence and quality of life.

Optimizing cardiopulmonary rehabilitation duration for long COVID patients: an exercise physiology monitoring approach

The presence of prolonged symptoms after COVID infection worsens the workability and quality of life. 200 adults with long COVID syndrome were enrolled after medical, physical, and mental screening, and were divided into two groups based on their performance. The intervention group (n = 100) received supervised rehabilitation at Department of Pulmonology, Semmelweis University with the registration number 160/2021 between 01/APR/2021-31/DEC/2022, while an age-matched control group (n = 100) received a single check-up. To evaluate the long-term effects of the rehabilitation, the intervention group was involved in a 2- and 3-month follow-up, carrying out cardiopulmonary exercise test. Our study contributes understanding long COVID rehabilitation, emphasizing the potential benefits of structured cardiopulmonary rehabilitation in enhancing patient outcomes and well-being. Significant difference was found between intervention group and control group at baseline visit in pulmonary parameters, as forced vital capacity, forced expiratory volume, forced expiratory volume, transfer factor for carbon monoxide, transfer coefficient for carbon monoxide, and oxygen saturation (all p < 0.05). Our follow-up study proved that a 2-week long, patient-centered pulmonary rehabilitation program has a positive long-term effect on people with symptomatic long COVID syndrome. Our data showed significant improvement between two and three months in maximal oxygen consumption (p < 0.05). Multidisciplinary, individualized approach may be a key element of a successful cardiopulmonary rehabilitation in long COVID conditions, which improves workload, quality of life, respiratory function, and status of patients with long COVID syndrome.

Effectiveness of exercise intervention on physical and health outcomes in patients admitted to an acute medical ward: A systematic review and meta-analysis

OBJECTIVE

To evaluate the effectiveness of inpatient medical ward exercise on physical and health outcomes in adults compared with usual care.

DATA SOURCES

Medline, CINAHL and EMBASE were searched from inception to 20 April 2023.

REVIEW METHODS

Randomised-controlled trials in English that reported physical and health outcomes of adults who received an exercise intervention on an acute medical ward were included. Two reviewers independently extracted data. Methodological quality was assessed using the PEDro and TESTEX scales. The GRADE rating assessed the quality of evidence to evaluate the certainty of effect. Meta-analyses were performed where possible.

RESULTS

Thirteen studies were included, with 1273 unique participants (mean [SD] age, 75.5 [11] years), which compared exercise intervention with usual care. Low quality evidence demonstrated a significant improvement in aerobic capacity ([MD], 1.39 m [95% CI, 0.23, 2.55], p = 0.02) and maximum isometric strength ([MD], 2.3 kg [95% CI, 2.2, 2.4], p < 0.001) for the exercise intervention compared with usual care. Low quality evidence demonstrated no difference for in-hospital falls count ([OR], 1.93 [95% CI, 0.61, 6.12] p = 0.27) or mortality ([OR], 0.77 [95% CI, 0.48, 1.23], p = 0.27). Moderate quality evidence demonstrated no difference for length of stay ([MD], -0.10 days [95% CI, -0.31, 0.11] p = 0.36).

CONCLUSION

Exercise prescribed during an acute medical ward stay improves aerobic capacity and maximum isometric strength but may not reduce length of stay, in-hospital falls or mortality.

Effect of Exercise Training on Prognosis in Community-acquired Pneumonia: A Randomized Controlled Trial

OBJECTIVE

To investigate the effect of standard care (SoC) combined with supervised in-bed cycling (Bed-Cycle) or booklet exercises (Book-Exe) versus SoC in community-acquired pneumonia (CAP).

METHODS

In this randomized controlled trial, 186 patients with CAP were assigned to SoC (n = 62), Bed-Cycle (n = 61), or Book-Exe (n = 63). Primary outcome length of stay (LOS) was analyzed with analysis of covariance. Secondary outcomes, 90-day readmission, and 180-day mortality were analyzed with Cox proportional hazard regression and readmission days with negative-binominal regression.

RESULTS

LOS was -2% (95% CI: -24 to 25) and -1% (95% CI: -22 to 27) for Bed-Cycle and Book-Exe, compared with SoC. Ninety-day readmission was 35.6% for SoC, 27.6% for Bed-Cycle, and 21.3% for Book-Exe. Adjusted hazard ratio (aHR) for 90-day readmission was 0.63 (95% CI: .33-1.21) and 0.54 (95% CI: .27-1.08) for Bed-Cycle and Book-Exe compared with SoC. aHR for 90-day readmission for combined exercise was 0.59 (95% CI: .33-1.03) compared with SoC. aHR for 180-day mortality was 0.84 (95% CI: .27-2.60) and 0.82 (95% CI: .26-2.55) for Bed-Cycle and Book-Exe compared with SoC. Number of readmission days was 226 for SoC, 161 for Bed-Cycle, and 179 for Book-Exe. Incidence rate ratio for readmission days was 0.73 (95% CI: .48-1.10) and 0.77 (95% CI: .51-1.15) for Bed-Cycle and Book-Exe compared with SoC.

CONCLUSIONS

Although supervised exercise training during admission with CAP did not reduce LOS or mortality, this trial suggests its potential to reduce readmission risk and number of readmission days.

Demystifying roles of exercise in immune response regulation against acute respiratory infections: A narrative review

The benefits of physical activity and exercise, especially those classified as moderate-to-vigorous activity (MVPA), have been well-established in preventing non-communicable diseases and mental health problems in healthy adults. However, the relationship between physical activity and exercise and the prevention and management of acute respiratory infection (ARI), a global high-burden disease, has been inconclusive. There have been debates and disagreements among scientific publications regarding the relationship between exercise and immune response against the causative agents of ARI. This narrative review aims to explore the theory that sufficiently explains the correlation between exercise, immune response, and ARI. The potential root causes of discrepancies come from research associated with the "open window" hypothesis. The studies have several limitations, and future improvements to address them are urgently needed in the study design, data collection, exercise intervention, subject recruitment, biomarkers for infection and inflammation, nutritional and metabolism status, and in addressing confounding variables. In conclusion, data support the clinical advantages of exercise have a regulatory contribution toward improving the immune response, which in turn potentially protects humans fromARI. However, the hypothesis related to its negative effect must be adopted cautiously.

Feasibility and Design Factors for Home-Based Pulmonary Rehabilitation of Patients With Chronic Obstructive Pulmonary Disease and Chronic Lung Diseases Based on a People-Object-Environment Framework: Qualitative Interview Study

BACKGROUND

The feasibility of implementing home-based pulmonary rehabilitation (PR) can be assessed from the perspectives of patients with chronic lung disease and health care professionals involved in PR.

OBJECTIVE

Through a qualitative inquiry using interviews and the adoption of the people-object-environment framework, this study aims to understand the influences of interpersonal, environmental, and situational factors on the perceptions and considerations of individuals involved in home-based PR for patients with chronic lung disease.

METHODS

One-on-one interviews were conducted with 20 patients with chronic lung disease and 20 health care professionals for investigating their attitudes and opinions based on their experiences regarding home-based PR as well as for identifying the key factors affecting the benefits and drawbacks of such therapies. This study further evaluates the feasibility of using digital tools for medical diagnosis and treatment by examining the technology usage of both parties.

RESULTS

The 4 key issues that all participants were the most concerned about were as follows: distance to outpatient medical care, medical efficiency, internet connectivity and equipment, and physical space for diagnosis and treatment. Interviews with patients and health care professionals revealed that the use of technology and internet was perceived differently depending on age and area of residence. Most participants reported that digital tools and internet connectivity had many benefits but still could not solve all the problems; moreover, these same digital tools and network transmission could lead to problems such as information security and digital divide concerns. This study also emphasizes the significant impact of human behavior and thinking on shaping the design of health care interventions and technologies. Understanding user perspectives and experiences is crucial for developing effective solutions for unmet needs.

CONCLUSIONS

The results of this study indicate that despite the different perspectives of patients and health care professionals, their considerations of the key issues are very similar. Therefore, the implementation of plans related to telemedicine diagnosis, treatment, or rehabilitation should take the suggestions and considerations of both parties into account as crucial factors for telehealth care design.

Smartphone-based inertial measurements during Chester step test as a predictor of length of hospital stay in abdominopelvic cancer postoperative period: a prospective cohort study

BACKGROUND

Objective assessment of pre-operative functional capacity in cancer patients using the smartphone gyroscope during the Chester step (CST) test may allow greater sensitivity of test results. This study has investigated whether the CST is a postoperative hospital permanence predictor in cancer patients undergoing abdominopelvic surgery through work, VO2MAX and gyroscopic movement analysis.

METHODS

Prospective, quantitative, descriptive and inferential observational cohort study. Fifty-one patients were evaluated using CST in conjunction with a smartphone gyroscope. Multivariate linear regression analysis was used to examine the predictive value of the CST.

RESULTS

The duration of hospital permanence 30 days after surgery was longer when patients who performed stage 1 showed lower RMS amplitude and higher peak power. The work increased as the test progressed in stage 3. High VO2MAX seemed to be a predictor of hospital permanence in those who completed levels 3 and 4 of the test.

CONCLUSION

The use of the gyroscope was more accurate in detecting mobility changes, which predicted a less favorable result for those who met at level 1 of the CST. VO2MAX was a predictor of prolonged hospitalization from level 3 of the test. The work was less accurate to determine the patient's true functional capacity.

Feasibility of a home-designed respiratory rehabilitation program for chronic obstructive pulmonary disease

BACKGROUND

According to international guidelines, respiratory rehabilitation (RR) for patients with chronic obstructive pulmonary disease (COPD) is a cornerstone of standard non-pharmacological treatment.

AIMS

To evaluate feasibility of a home-designed RR program and analyze its medium-term impact on respiratory parameters and quality of life.

METHODS

This was a prospective study involving 74 COPD patients enrolled in January 2019 and put on inhaled bronchodilator treatment associated with RR at home following a written protocol, for 16 weeks. The comparative statistical analysis highlights the difference before and after RR in terms of clinical and functional respiratory parameters as well as in terms of quality of life (assessed on the short form 36 (SF-36) questionnaire). The comparison involves RR-adherent patients versus non-adherent patients.

RESULTS

Mean age was 66.7 ± 8.3 years with a median of 67 years. All patients were smokers, out of which 42 patients (57%) did not quit yet. Forty-one percent of patients were frequent exacerbators. The average COPD assessment test (CAT) score in our patients was 23. The average 6-minutes walk distance (MWD) was 304 m. The BODE index in our patients was 4.11 on average. The RR program was followed by 36 patients (48%). Thirty patients (40%) applied it at least twice a week. RR-adherent patients had an average CAT score decreasing from 23 to 14.5 (P = 0.011). Their average 6-MWD was 444.6 m by the end of the study, which would be 64.2% of the calculated theoretical value. The average FEV1 increase after RR was 283 mL. The majority (69%) of RR-adherent patients were ranked as quartile 1; BODE index ≤2. The average scores of physical, psycho-social, and general dimensions assessed on the SF-36 questionnaire improved in RR-adherent patients.

CONCLUSIONS

RR is a key non-pharmacological treatment for COPD. Its interest originates from its multidisciplinary nature, hence its effectiveness in several respiratory parameters. Our study reflects the feasibility of home-designed protocols in the absence of contraindications. We highlight also the positive impact on quality of life after RR at home.

The effects of neuromuscular electrical stimulation on hospitalised adults: systematic review and meta-analysis of randomised controlled trials

INTRODUCTION

Neuromuscular electrical stimulation (NMES) is a treatment to prevent or reverse acquired disability in hospitalised adults. We conducted a systematic review and meta-analysis of its effectiveness.

METHOD

We searched MEDLINE, EMBASE, Cumulative Index to Nursing & Allied Health (CINAHL) and the Cochrane library. Inclusion criteria: randomised controlled trials of hospitalised adult patients comparing NMES to control or usual care. The primary outcome was muscle strength. Secondary outcomes were muscle size, function, hospital length of stay, molecular and cellular biomarkers, and adverse effects. We assessed risk of bias using the Cochrane risk-of-bias tool. We used Review Manager (RevMan) software for data extraction, critical appraisal and synthesis. We assessed certainty using the Grading of Recommendations Assessment, Development and Evaluation tool.

RESULTS

A total of 42 papers were included involving 1,452 participants. Most studies had unclear or high risk of bias. NMES had a small effect on muscle strength (moderate certainty) (standardised mean difference (SMD) = 0.33; P < 0.00001), a moderate effect on muscle size (moderate certainty) (SMD = 0.66; P < 0.005), a small effect on walking performance (moderate certainty) (SMD = 0.48; P < 0.0001) and a small effect on functional mobility (low certainty) (SMD = 0.31; P < 0.05). There was a small and non-significant effect on health-related quality of life (very low certainty) (SMD = 0.35; P > 0.05). In total, 9% of participants reported undesirable experiences. The effects of NMES on length of hospital stay, and molecular and cellular biomarkers were unclear.

CONCLUSIONS

NMES is a promising intervention component that might help to reduce or prevent hospital-acquired disability.

Predictors of Length of Stay, Rehospitalization and Mortality in Community-Acquired Pneumonia Patients: A Retrospective Cohort Study

BACKGROUND

Community-acquired pneumonia (CAP) represents one of the leading causes of hospitalization and has a substantial impact on the financial burden of healthcare. The aim of this study was to identify factors associated with the length of hospital stay (LOHS), rehospitalization and mortality of patients admitted for CAP.

METHODS

A retrospective cohort study was conducted with patients presenting to a Swiss public hospital between January 2019 and December 2019. Zero-truncated negative binomial and multivariable logistic regression analyses were performed to assess risk factors.

RESULTS

A total of 300 patients were analyzed (median 78 years, IQR [67.56, 85.50] and 53% males) with an average LOHS of 7 days (IQR [5.00, 9.00]). Of the 300 patients, 31.6% (97/300) were re-hospitalized within 6 months, 2.7% (8/300) died within 30 days and 11.7% (35/300) died within 1 year. The results showed that sex (IRR = 0.877, 95% CI = 0.776-0.992, p-value = 0.036), age (IRR = 1.007, 95% CI = 1.002-1.012, p-value = 0.003), qSOFA score (IRR = 1.143, 95% CI = 1.049-1.246, p-value = 0.002) and atypical pneumonia (IRR = 1.357, 95% CI = 1.012-1.819, p-value = 0.04) were predictive of LOHS. Diabetes (OR = 2.149, 95% CI = 1.104-4.172, p-value = 0.024), a higher qSOFA score (OR = 1.958, 95% CI = 1.295-3.002, p-value = 0.002) and rehabilitation after discharge (OR = 2.222, 95% CI = 1.017-4.855, p-value = 0.044) were associated with a higher chance of being re-hospitalized within 6 months, whereas mortality within 30 days and within one year were both associated with older age (OR = 1.248, 95% CI = 1.056-1.562, p-value = 0.026 and OR = 1.073, 95% CI = 1.025-1.132, p-value = 0.005, respectively) and the presence of a cancer diagnosis (OR = 32.671, 95% CI = 4.787-369.1, p-value = 0.001 and OR = 4.408, 95% CI = 1.680-11.43, p-value = 0.002, respectively).

CONCLUSION

This study identified routinely available predictors for LOHS, rehospitalization and mortality in patients with CAP, which may further advance our understanding of CAP and thereby improve patient management, discharge planning and hospital costs.

Impact of Pneumonia on Cognitive Aging: A Longitudinal Propensity-Matched Cohort Study

BACKGROUND

Acute clinical events, such as pneumonia, may impact physical functionality but their effect on cognition and the possible duration of this effect remains to be quantified. This study investigated the impact of pneumonia on cognitive trajectories and dementia development in older people.

METHODS

Data were obtained from 60+ years old individuals, who were assessed from 2001 to 2018 in the population-based SNAC-K study (Sweden). Participants were eligible if they were not institutionalized, had no dementia, and did not experience pneumonia 5 years prior to baseline (N = 2 063). A propensity score was derived to match 1:3 participants hospitalized with a diagnosis of pneumonia (N = 178), to nonexposed participants (N = 534). Mixed linear models were used to model cognitive decline. The hazard of dementia, clinically diagnosed by physicians following Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV, was estimated using Cox regression models.

RESULTS

We found a transient impact of pneumonia on cognitive decline in the first 2.5 years (B = -0.94, 95% confidence interval [CI] -1.75, -0.15). The hazard ratio (HR) for dementia was not statistically significantly increased in pneumonia participants (HR = 1.17, 95%CI 0.82, 1.66).

CONCLUSIONS

The transient impact of pneumonia on cognitive function suggests an increased need of health care for patients after a pneumonia-related hospitalization and reinforces the relevance of pneumonia prevention.

Change over time in functional capacity and self-perceived health status for patients with chronic musculoskeletal pain: a registry-based longitudinal study

BACKGROUND AND AIMS

Chronic musculoskeletal pain is a major public health problem worldwide. Both self-reported functional capacity and self-perceived health status are reduced in patients with chronic musculoskeletal pain. Previous studies mostly assessed functional capacity through self-reported questionnaires instead of objective measurements. The aim of this study, therefore, is to assess the amount of change over time and its clinical meaningfulness in functional capacity and self-perceived health status of patients with chronic musculoskeletal pain undergoing Bern Ambulatory Interprofessional Rehabilitation (BAI-Reha).

METHODS

The registry-based longitudinal cohort study with prospectively collected data from a rehabilitation programme took place in a real-life setting. Patients (n = 81) with chronic musculoskeletal pain took part in the BAI-Reha. The main outcomes were the six-minute-walk test (6MWT), the safe maximum floor-to-waist lift (SML) and the European Quality of Life and Health measure visual analogue scale (EQ VAS). Timepoints of measurement were at baseline and post-BAI-Reha (i.e., at 4 months). The quantity of interest was the adjusted time effect (point estimate, 95% confidence interval, and p-value for testing the null hypothesis of no change over time). Statistical significance (α = 0.05) and clinical meaningfulness of the mean value change over time were assessed using predefined thresholds (six-minute-walk test 50 m, SML 7 kg, and EQ VAS 10 points).

RESULTS

The linear mixed model analysis showed a statistically significant change over time for the six-minute-walk test (mean value change 56.08 m, 95% CI [36.13, 76.03]; p <0.001), SML (mean value change 3.92 kg, 95% CI [2.66, 5.19]; p <0.001), and EQ VAS (mean value change 9.58 points, 95% CI [4.87, 14.28]; p <0.001). Moreover, the improvement in the six-minute-walk test is clinically meaningful (mean value change 56.08 m) and almost clinically meaningful (mean value change 9.58 points) in the EQ VAS.

CONCLUSION

Patients walk further, lift more weight, and feel healthier after interprofessional rehabilitation when compared to baseline measurement. These findings confirm and add to previous results.

IMPLICATIONS

We encourage other providers of rehabilitation for patients with chronic musculoskeletal pain to measure functional capacity with objective outcome variables and to use self-reported outcome measures in addition to self-perceived health status. The well-established assessments used in this study are suitable for this purpose.

Greater exercise tolerance in COPD during acute intermittent compared to continuous shuttle walking protocols: A proof-of-concept study

Objectives: Ground-based walking is a simple training modality which would suit pulmonary rehabilitation (PR) settings with limited access to specialist equipment. Patients with COPD are, however, unable to walk uninterruptedly at a relatively fast walking pace to optimise training benefits. We compared an intermittent (IntSW) to a continuous (CSW) shuttle walking protocol.Methods: In 14 COPD patients (mean ± SD. FEV₁: 45 ± 21% predicted) we measured walking distance, cardiac output (CO), arterial oxygen saturation (SpO₂), and symptoms during (a) an IntSW protocol, consisting of 1-min walking alternating with 1-min rest, and (b) a CSW protocol, both sustained at 85% of predicted VO₂ peak to the limit of tolerance (Tlim).Results: Median (IQR) distance was greater (p = 0.001) during the IntSW protocol (735 (375-1107) m) than the CSW protocol (190 (117-360) m). At iso-distance (distance at Tlim during CSW) the IntSW compared to the CSW protocol was associated with lower CO (8.6 ± 2.6 vs 10.3 ± 3.7 L/min; p = 0.013), greater SpO₂ (92 ± 6% versus 90 ± 7%; p = 0.002), and lower symptoms of dyspnoea (2.8 ± 1.3 vs 4.9 ± 1.4; p = 0.001) and leg discomfort (2.3 ± 1.7 vs 4.2 ± 2.2; p = 0.001). At Tlim symptoms of dyspnoea and leg discomfort did not differ between the IntSW (4.4 ± 1.9 and 3.6 ± 2.1, respectively) and the CSW protocol.Conclusions: The IntSW protocol may provide important clinical benefits during exercise training in the PR settings because it allows greater work outputs compared to the CSW.

Exercise for acutely hospitalised older medical patients

BACKGROUND

Approximately 30% of hospitalised older adults experience hospital-associated functional decline. Exercise interventions that promote in-hospital activity may prevent deconditioning and thereby maintain physical function during hospitalisation. This is an update of a Cochrane Review first published in 2007.

OBJECTIVES

To evaluate the benefits and harms of exercise interventions for acutely hospitalised older medical inpatients on functional ability, quality of life (QoL), participant global assessment of success and adverse events compared to usual care or a sham-control intervention.

SEARCH METHODS

We used standard, extensive Cochrane search methods. The latest search date was May 2021.

SELECTION CRITERIA

We included randomised or quasi-randomised controlled trials evaluating an in-hospital exercise intervention in people aged 65 years or older admitted to hospital with a general medical condition. We excluded people admitted for elective reasons or surgery.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods. Our major outcomes were 1. independence with activities of daily living; 2. functional mobility; 3. new incidence of delirium during hospitalisation; 4. QoL; 5. number of falls during hospitalisation; 6. medical deterioration during hospitalisation and 7. participant global assessment of success. Our minor outcomes were 8. death during hospitalisation; 9. musculoskeletal injuries during hospitalisation; 10. hospital length of stay; 11. new institutionalisation at hospital discharge; 12. hospital readmission and 13. walking performance. We used GRADE to assess certainty of evidence for each major outcome. We categorised exercise interventions as: rehabilitation-related activities (interventions designed to increase physical activity or functional recovery, but did not follow a specified exercise protocol); structured exercise (interventions that included an exercise intervention protocol but did not include progressive resistance training); and progressive resistance exercise (interventions that included an element of progressive resistance training).

MAIN RESULTS

We included 24 studies (nine rehabilitation-related activity interventions, six structured exercise interventions and nine progressive resistance exercise interventions) with 7511 participants. All studies compared exercise interventions to usual care; two studies, in addition to usual care, used sham interventions. Mean ages ranged from 73 to 88 years, and 58% of participants were women. Several studies were at high risk of bias. The most common domain assessed at high risk of bias was measurement of the outcome, and five studies (21%) were at high risk of bias arising from the randomisation process. Exercise may have no clinically important effect on independence in activities of daily living at discharge from hospital compared to controls (16 studies, 5174 participants; low-certainty evidence). Five studies used the Barthel Index (scale: 0 to 100, higher scores representing greater independence). Mean scores at discharge in the control groups ranged from 42 to 96 points, and independence in activities of daily living was 1.8 points better (0.43 worse to 4.12 better) with exercise compared to controls. The minimally clinical important difference (MCID) is estimated to be 11 points. We are uncertain regarding the effect of exercise on functional mobility at discharge from the hospital compared to controls (8 studies, 2369 participants; very low-certainty evidence). Three studies used the Short Physical Performance Battery (SPPB) (scale: 0 to 12, higher scores representing better function) to measure functional mobility. Mean scores at discharge in the control groups ranged from 3.7 to 4.9 points on the SPPB, and the estimated effect of the exercise interventions was 0.78 points better (0.02 worse to 1.57 better). A change of 1 point on the SPPB represents an MCID. We are uncertain regarding the effect of exercise on the incidence of delirium during hospitalisation compared to controls (7 trials, 2088 participants; very low-certainty evidence). The incidence of delirium during hospitalisation was 88/1091 (81 per 1000) in the control group compared with 70/997 (73 per 1000; range 47 to 114) in the exercise group (RR 0.90, 95% CI 0.58 to 1.41). Exercise interventions may result in a small clinically unimportant improvement in QoL at discharge from the hospital compared to controls (4 studies, 875 participants; low-certainty evidence). Mean QoL on the EuroQol 5 Dimensions (EQ-5D) visual analogue scale (VAS) (scale: 0 to 100, higher scores representing better QoL) ranged between 48.9 and 64.7 in the control group at discharge from the hospital, and QoL was 6.04 points better (0.9 better to 11.18 better) with exercise. A change of 10 points on the EQ-5D VAS represents an MCID. No studies measured participant global assessment of success. Exercise interventions did not affect the risk of falls during hospitalisation (moderate-certainty evidence). The incidence of falls was 31/899 (34 per 1000) in the control group compared with 31/888 (34 per 1000; range 20 to 57) in the exercise group (RR 0.99, 95% CI 0.59 to 1.65). We are uncertain regarding the effect of exercise on the incidence of medical deterioration during hospitalisation (very low-certainty evidence). The incidence of medical deterioration in the control group was 101/1417 (71 per 1000) compared with 96/1313 (73 per 1000; range 44 to 120) in the exercise group (RR 1.02, 95% CI 0.62 to 1.68). Subgroup analyses by different intervention categories and by the use of a sham intervention were not meaningfully different from the main analyses.

AUTHORS' CONCLUSIONS

Exercise may make little difference to independence in activities of daily living or QoL, but probably does not result in more falls in older medical inpatients. We are uncertain about the effect of exercise on functional mobility, incidence of delirium and medical deterioration. Certainty of evidence was limited by risk of bias and inconsistency. Future primary research on the effect of exercise on acute hospitalisation could focus on more consistent and uniform reporting of participant's characteristics including their baseline level of functional ability, as well as exercise dose, intensity and adherence that may provide an insight into the reasons for the observed inconsistencies in findings.

Association between Barthel Index, Grip Strength, and Physical Activity Level at Admission and Prognosis in Community-Acquired Pneumonia: A Prospective Cohort Study

Background: Impaired functional status is a risk factor for hospitalization in patients with community-acquired pneumonia (CAP). The aim was to determine the influence of functional status and physical activity level on severe outcomes, including length of stay, admission to the intensive care unit (ICU), readmission, and mortality in patients with CAP. Methods: A prospective cohort study among patients hospitalized with CAP. Functional status was assessed with the Barthel index and grip strength, and physical activity level was assessed using the international physical activity questionnaire. Linear regression was used to assess the association with length of stay, and logistic regression was used to assess the risk of severe outcomes. Results: Among 355 patients admitted with CAP, 18% had a low Barthel index (<80), 45% had a low grip strength, and 75% had a low physical activity level. Low Barthel index was associated with increased risk of ICU admission (OR 3.6, 95% CI 1.2−10.9), longer length of stay (27.9%, 95% CI 2.3−59.7%), readmission within 30, 90, and 180 days (OR 2.1−2.4, p < 0.05), and mortality within 90 and 180 days (OR 4.2−5.0, p < 0.05). Low grip strength was associated with increased risk of 90 days readmission (OR 1.6, 95% CI 1.0−2.6, p < 0.05) and mortality within 30, 90, and 180 days (OR 2.6−3.2, p < 0.05). Low physical activity level was associated with increased risk of readmission within 90 and 180 days (OR 1.8−2.1, p < 0.05) and mortality within 30, 90, and 180 days (OR 3.3−5.5, p < 0.05). Conclusions: Impaired functional status and low physical activity level were associated with a longer length of stay and increased risk of ICU admission, readmission, and mortality in patients hospitalized with CAP. Routine assessment of functional status and physical activity level in clinical care could enable early identification of individuals with excess risk for a poor prognosis.

Is rehabilitation effective in preventing decreased functional status after community-acquired pneumonia in elderly patients? Results from a multicentre, retrospective observational study

OBJECTIVES

This study was designed to evaluate the effect of rehabilitation in preventing decreased functional status (FS) after community-acquired pneumonia (CAP) in elderly patients.

DESIGN

This was a retrospective observational study.

SETTING

Multicentre study was conducted in two medical facilities from January 2016 to December 2018.

PARTICIPANTS

Hospitalised patients with CAP aged over 64 years were enrolled. FS was assessed by the Barthel Index (BI) (range, 0-100, in 5-point increments) at admission and before discharge and graded into three categories: independent, BI 80-100; semidependent, BI 30-75; and dependent, BI 0-25. Multivariable analysis of factors contributing to decreased FS was conducted with two groups: with a decrease of at least one category (decreased group) or without a decrease of category (maintained group).

PRIMARY AND SECONDARY OUTCOME MEASURES

The primary outcome was the effect of rehabilitation in preventing decreased FS. The secondary outcomes were factors associated with decreased FS.

RESULTS

The maintained and decreased groups included 400 and 138 patients, respectively. A high frequency of rehabilitation therapy was observed in the decreased group (189 (47.3%) vs 104 (75.4%); p<0.001). Multivariable analysis showed that the factors affecting FS were aspiration pneumonia, Pneumonia Severity Index (PSI) category V, length of stay and age (OR 2.66, 95% CI 1.58 to 4.49; OR 1.92, 95% CI 1.29 to 3.44; OR 1.05, 95% CI 1.04 to 1.07; and OR 1.05, 95% CI 1.02 to 1.09, respectively). After adjusting for factors contributing to decreased FS, rehabilitation showed a limited effect in preventing decreased FS in 166 matched pairs by McNemar's test (p=0.327).

CONCLUSIONS

Aspiration and PSI played important roles in reducing FS. The effect of rehabilitation remains unclear in CAP.

Chest physiotherapy for pneumonia in adults

BACKGROUND

Despite conflicting evidence, chest physiotherapy has been widely used as an adjunctive treatment for adults with pneumonia. This is an update of a review first published in 2010 and updated in 2013.

OBJECTIVES

To assess the effectiveness and safety of chest physiotherapy for pneumonia in adults.

SEARCH METHODS

We updated our searches in the following databases to May 2022: the Cochrane Central Register of Controlled Trials (CENTRAL) via OvidSP, MEDLINE via OvidSP (from 1966), Embase via embase.com (from 1974), Physiotherapy Evidence Database (PEDro) (from 1929), CINAHL via EBSCO (from 2009), and the Chinese Biomedical Literature Database (CBM) (from 1978).

SELECTION CRITERIA

Randomised controlled trials (RCTs) and quasi-RCTs assessing the efficacy of chest physiotherapy for treating pneumonia in adults.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane.

MAIN RESULTS

We included two new trials in this update (540 participants), for a total of eight RCTs (974 participants). Four RCTs were conducted in the United States, two in Sweden, one in China, and one in the United Kingdom. The studies looked at five types of chest physiotherapy: conventional chest physiotherapy; osteopathic manipulative treatment (OMT, which includes paraspinal inhibition, rib raising, and myofascial release); active cycle of breathing techniques (which includes active breathing control, thoracic expansion exercises, and forced expiration techniques); positive expiratory pressure; and high-frequency chest wall oscillation. We assessed four trials as at unclear risk of bias and four trials as at high risk of bias. Conventional chest physiotherapy (versus no physiotherapy) may have little to no effect on improving mortality, but the certainty of evidence is very low (risk ratio (RR) 1.03, 95% confidence interval (CI) 0.15 to 7.13; 2 trials, 225 participants; I² = 0%). OMT (versus placebo) may have little to no effect on improving mortality, but the certainty of evidence is very low (RR 0.43, 95% CI 0.12 to 1.50; 3 trials, 327 participants; I² = 0%). Similarly, high-frequency chest wall oscillation (versus no physiotherapy) may also have little to no effect on improving mortality, but the certainty of evidence is very low (RR 0.75, 95% CI 0.17 to 3.29; 1 trial, 286 participants). Conventional chest physiotherapy (versus no physiotherapy) may have little to no effect on improving cure rate, but the certainty of evidence is very low (RR 0.93, 95% CI 0.56 to 1.55; 2 trials, 225 participants; I² = 85%). Active cycle of breathing techniques (versus no physiotherapy) may have little to no effect on improving cure rate, but the certainty of evidence is very low (RR 0.60, 95% CI 0.29 to 1.23; 1 trial, 32 participants). OMT (versus placebo) may improve cure rate, but the certainty of evidence is very low (RR 1.59, 95% CI 1.01 to 2.51; 2 trials, 79 participants; I² = 0%). OMT (versus placebo) may have little to no effect on mean duration of hospital stay, but the certainty of evidence is very low (mean difference (MD) -1.08 days, 95% CI -2.39 to 0.23; 3 trials, 333 participants; I² = 50%). Conventional chest physiotherapy (versus no physiotherapy, MD 0.7 days, 95% CI -1.39 to 2.79; 1 trial, 54 participants) and active cycle of breathing techniques (versus no physiotherapy, MD 1.4 days, 95% CI -0.69 to 3.49; 1 trial, 32 participants) may also have little to no effect on duration of hospital stay, but the certainty of evidence is very low. Positive expiratory pressure (versus no physiotherapy) may reduce the mean duration of hospital stay by 1.4 days, but the certainty of evidence is very low (MD -1.4 days, 95% CI -2.77 to -0.03; 1 trial, 98 participants). Positive expiratory pressure (versus no physiotherapy) may reduce the duration of fever by 0.7 days, but the certainty of evidence is very low (MD -0.7 days, 95% CI -1.36 to -0.04; 1 trial, 98 participants). Conventional chest physiotherapy (versus no physiotherapy, MD 0.4 days, 95% CI -1.01 to 1.81; 1 trial, 54 participants) and OMT (versus placebo, MD 0.6 days, 95% CI -1.60 to 2.80; 1 trial, 21 participants) may have little to no effect on duration of fever, but the certainty of evidence is very low. OMT (versus placebo) may have little to no effect on the mean duration of total antibiotic therapy, but the certainty of evidence is very low (MD -1.07 days, 95% CI -2.37 to 0.23; 3 trials, 333 participants; I² = 61%). Active cycle of breathing techniques (versus no physiotherapy) may have little to no effect on duration of total antibiotic therapy, but the certainty of evidence is very low (MD 0.2 days, 95% CI -4.39 to 4.69; 1 trial, 32 participants). High-frequency chest wall oscillation plus fibrobronchoscope alveolar lavage (versus fibrobronchoscope alveolar lavage alone) may reduce the MD of intensive care unit (ICU) stay by 3.8 days (MD -3.8 days, 95% CI -5.00 to -2.60; 1 trial, 286 participants) and the MD of mechanical ventilation by three days (MD -3 days, 95% CI -3.68 to -2.32; 1 trial, 286 participants), but the certainty of evidence is very low. One trial reported transient muscle tenderness emerging after OMT in two participants. In another trial, three serious adverse events led to early withdrawal after OMT. One trial reported no adverse events after positive expiratory pressure treatment. Limitations of this review were the small sample size and unclear or high risk of bias of the included trials.

AUTHORS' CONCLUSIONS

The inclusion of two new trials in this update did not change the main conclusions of the original review. The current evidence is very uncertain about the effect of chest physiotherapy on improving mortality and cure rate in adults with pneumonia. Some physiotherapies may slightly shorten hospital stays, fever duration, and ICU stays, as well as mechanical ventilation. However, all of these findings are based on very low certainty evidence and need to be further validated.

Functional improvement after inpatient rehabilitation in community hospitals following acute hospital care

INTRODUCTION

There are limited studies exploring functional improvement in relation to characteristics of patients who, following acute hospital care, receive inpatient rehabilitation in community hospitals. We evaluated the association of acute hospital admission-related factors with functional improvement on community hospital discharge.

METHODS

We conducted a retrospective cohort study among patients who were transferred to community hospitals within 14-day post-discharge from acute hospital between 2016 and 2018. Modified Barthel Index (MBI) on a 100-point ordinal scale was used to assess functional status on admission to and discharge from the community hospital. We categorised MBI into 6 bands: 0-24, 25-49, 50-74, 75-90, 91-99 and 100. Multivariable logistic regression models were constructed to determine factors associated with categorical improvement in functional status, defined as an increase in at least one MBI band between admission and discharge.

RESULTS

A total of 5,641 patients (median age 77 years, interquartile range 69-84; 44.2% men) were included for analysis. After adjusting for potential confounders, factors associated with functional improvement were younger age, a higher MBI on admission, and musculoskeletal diagnosis for the acute hospital admission episode. In contrast, a history of dementia or stroke; lower estimated glomerular filtration rate; abnormal serum albumin or anaemia measured during the acute hospital episode; and diagnoses of stroke, cardiac disease, malignancy, falls or pneumonia; and other chronic respiratory diseases were associated with lower odds of functional improvement.

CONCLUSION

Clinicians may want to take into account the presence of these high-risk factors in their patients when planning rehabilitation programmes, in order to maximise the likelihood of functional improvement.

Resistance Training before, during, and after COVID-19 Infection: What Have We Learned So Far?

At the end of 2019, a severe acute respiratory syndrome caused by SARS-CoV-2 started a pandemic, leading to millions of deaths and many important political and social changes. Even in the absence of contamination, the mobility reduction, social distancing and closing of exercise facilities negatively affected physical activity and conditioning, which is associated with muscle atrophy, loss of muscle strength, and reductions in functional capacity. In cases of infection, it has been shown that increased physical capacity is associated with decreased hospitalization and mortality risk. Although millions of people have died from COVID-19, most contaminated individuals survived the infection, but carried different sequelae, such as the severe loss of physical function and a reduced quality of life. Among different physical exercise models that might help to prevent and treat COVID-19-related conditions, resistance training (RT) might be particularly relevant. Among its benefits, RT can be adapted to be performed in many different situations, even with limited space and equipment, and is easily adapted to an individual's characteristics and health status. The current narrative review aims to provide insights into how RT can be used in different scenarios to counteract the negative effects of COVID-19. By doing this, the authors expect to provide insights to help deal with the current pandemic and similar events the world may face in the future.

Functional exercise capacity in rheumatoid arthritis unrelated to lung injury: A comparison of women with and without rheumatoid disease

BACKGROUND

Rheumatoid arthritis (RA) mainly affects the joints of the upper and lower limbs, so evaluating functional exercise capacity in individuals with RA via dynamic tests of the locomotor system is essential.

OBJECTIVES

To compare functional exercise capacity using the Glittre-activities of daily living (ADL) test (G-AT) in women with and without RA in the absence of RA pulmonary disease (RA-PD) and to correlate the findings with hand functioning, physical functioning, handgrip strength (HGS), and quadriceps strength (QS).

METHODS

This cross-sectional pilot study evaluated 35 women with RA and 25 healthy controls by assessing hand functioning using the Cochin Hand Functional Scale (CHFS), physical functioning with the Health Assessment Questionnaire Disability Index (HAQ-DI), muscle functioning using HGS and QS, and G-AT results.

RESULTS

Compared to the women in the control group, the women with RA presented higher scores for the CHFS (p< 0.0001) and HAQ-DI (p< 0.0001) and lower HGS (p< 0.0001) and QS (p= 0.013) values. The median G-AT time was higher in the RA patients than in the healthy controls [300 (295-420) vs. 180 (155-203) s], p< 0.0001), and the greatest difficulty reported by patients after the G-AT was squatting to perform the shelving tasks. G-AT time was positively correlated with the HAQ-DI (rs= 0.668, p< 0.0001) and CHFS (rs= 0.586, p= 0.0007) and negatively correlated with QS (rs=-0.429, p= 0.037). There was no significant correlation between the G-AT time and HGS.

CONCLUSIONS

Women with RA take longer to perform G-AT tasks. Moreover, G-AT time was associated with hand functioning, physical functioning and QS, but not with HGS.

A mixed-methods feasibility study of a sit-to-stand based exercise programme to maintain knee-extension muscle strength for older patients during hospitalisation

Objectives:

To determine the acceptability of an exercise programme and to identify barriers and facilitators to compliance with the programme from the participants’ perspective.

Methods:

Patients aged 75 years or older were recruited within the first 36 hours of hospital admission. Participants were randomised to complete two strengthening-based (intervention arm) or stretching-based (control arm) exercise sessions per-day. At hospital discharge, participants were asked to take part in interviews with a member of the research team exploring the barriers and facilitators to adherence to the intervention.

Results:

15 participants (7 intervention arm, 8 control arm) were recruited before the trial was stopped due to COVID-19. Both groups showed reductions in knee-extension strength, and improvements in functional mobility at discharge from hospital. A total of 23/60 intervention sessions were classed as ‘complete’, 12/60 as partially complete, and 25/60 were missed entirely. Eight participants took part in interviews. Intrinsic factors that impacted participation in the research, related to current health, health beliefs, and experience of multi-morbidity or functional decline. Staff had both a positive and negative effect on participant adherence to the intervention.

Conclusions:

The exercise intervention was well received, with most participants describing health benefits, though intervention fidelity was lower than expected.

Role of Exercise Intensity on Th1/Th2 Immune Modulations During the COVID-19 Pandemic

The COVID-19 pandemic has led to several pioneering scientific discoveries resulting in no effective solutions with the exception of vaccination. Moderate exercise is a significant non-pharmacological strategy, to reduce the infection-related burden of COVID-19, especially in patients who are obese, elderly, and with additional comorbidities. The imbalance of T helper type 1 (Th1) or T helper type 2 (Th2) cells has been well documented among populations who have suffered as a result of the COVID-19 pandemic, and who are at maximum risk of infection and mortality. Moderate and low intensity exercise can benefit persons at risk from the disease and survivors by favorable modulation in Th1/Th2 ratios. Moreover, in COVID-19 patients, mild to moderate intensity aerobic exercise also increases immune system function but high intensity aerobic exercise may have adverse effects on immune responses. In addition, sustained hypoxia in COVID-19 patients has been reported to cause organ failure and cell death. Hypoxic conditions have also been highlighted to be triggered in COVID-19-susceptible individuals and COVID-19 survivors. This suggests that hypoxia inducible factor (HIF 1α) might be an important focus for researchers investigating effective strategies to minimize the effects of the pandemic. Intermittent hypoxic preconditioning (IHP) is a method of exposing subjects to short bouts of moderate hypoxia interspersed with brief periods of normal oxygen concentrations (recovery). This methodology inhibits the production of pro-inflammatory factors, activates HIF-1α to activate target genes, and subsequently leads to a higher production of red blood cells and hemoglobin. This increases angiogenesis and increases oxygen transport capacity. These factors can help alleviate virus induced cardiopulmonary hemodynamic disorders and endothelial dysfunction. Therefore, during the COVID-19 pandemic we propose that populations should engage in low to moderate exercise individually designed, prescribed and specific, that utilizes IHP including pranayama (yoga), swimming and high-altitude hiking exercise. This would be beneficial in affecting HIF-1α to combat the disease and its severity. Therefore, the promotion of certain exercises should be considered by all sections of the population. However, exercise recommendations and prescription for COVID-19 patients should be structured to match individual levels of capability and adaptability.

Six-month outcomes and effect of pulmonary rehabilitation among patients hospitalized with COVID-19: a retrospective cohort study

BACKGROUND

Patients appear to maintain sequelae post-coronavirus disease 2019 (COVID-19) affecting daily life and physical health. We investigated the changes in and the effects of pulmonary rehabilitation (PR) on exercise capacity and immunology six months after COVID-19 hospitalization.

METHODS

This retrospective cohort reviewed 233 COVID-19 patients admitted from 17 January 2020 to 29 February 2020. Ninety-eight patients who completed 2-week and 6-month follow-ups and tests were included. Among 98 patients, 27 completed at least five sessions of PR at the First Hospital of Changsha, China, during the 6-month convalescence were allocated to the PR group; the reminder who had not performed any PR were assigned to the control group. The primary outcome was the change in six-minute walk distance (6-MWD) between the 2-week and 6-month follow-ups, which was assessed via analysis of covariance with a covariate of propensity score that adjusted for the potential confounders. Secondary outcomes were the changes in 6-MWD, SARS-CoV-2 immunoglobulins, T-lymphocytes and blood chemistry, which were evaluated via paired tests.

RESULTS

Participants' ages ranged from 19 to 84 years (M = 47, standard deviation (SD)=15) 45.9% identified as male. During the 6-month convalescence, 6-MWD increased 27.0%, with a mean [95% CI] of 113 [92-134] m (p < .001). SARS-CoV-2 IgG and IgM decreased 33.3% (p = .002) and 43.8% (p = .009), CD4+ T cells increased 7.9% (p = .04), and the majority of blood chemistry significantly changed. The patients in the PR group acquired a greater increase in 6-MWD than those in control (unadjusted, 194 [167-221] m, p < .001; adjusted, 123 [68-181] m, p < .001), dose-responsiveness of PR on 6-MWD was observed (p < .001). No differences in immunity variables and blood chemistry were observed between groups.

CONCLUSIONS

These findings suggest PR may be a strategy to promote the improvement of exercise capacity after COVID-19.

The Glittre Activities of Daily Living Test in patients with acromegaly: Associations with hand function and health-related quality of life

BACKGROUND

Musculoskeletal disorders in acromegaly compromise upper and lower limb activity. Corresponding changes can be better assessed by a functional capacity test incorporating multitasking, such as the Glittre Activities of Daily Living Test (GA-T).

OBJECTIVES

To evaluate functional capacity in adults with acromegaly using the GA-T and to correlate functional capacity with hand function and health-related quality of life.

METHODS

The GA-T was applied to 36 patients with acromegaly and an equal number of healthy individuals. Additionally, participants completed the Acromegaly Quality of Life (AcroQoL) questionnaire and underwent a chronic pain assessment using a map of the human body, a hand function evaluation using the Cochin Hand Functional Scale (CHFS), and a handgrip strength test.

RESULTS

Relative to the comparison group, patients with acromegaly required more time to perform the GA-T, showed worse hand function, and reported that squatting to accomplish shelving tasks was the major difficulty. GA-T time was correlated with the AcroQoL global score, handgrip strength, and the CHFS (rs=-0.487, p= 0.002; rs=-0.369, p= 0.026; rs= 0.538, p= 0.0007, respectively).

CONCLUSIONS

Patients with acromegaly exhibited a reduced functional capacity as assessed by the GA-T. Additionally, an association was identified between the total GA-T time and both hand function and quality of life.

Pneumonia prevention in the elderly patients: the other sides

Pneumonia is one of the leading causes of morbidity and mortality from infection in elderly patients. The increased frequency of pneumonia among elderly subjects can be explained by the physiological changes linked to the progressive aging of the respiratory tree and the diminished immunological response. A spiral of event leads to frailty, infection and possible death; preventing pneumonia consists of controlling the risk factors. Dysphagia, which is associated with malnutrition and dehydration, is recognized as one of the major pathophysiological mechanism leading to pneumonia and its screening is crucial for the pneumonia risk assessment. The impairment in the oropharyngeal reflexes results in stagnation of foreign material in the lateral cavities of the pharynx which may then get aspirated repeatedly in the lungs and cause pneumonia. Pneumonia prevention starts with lifestyle modifications such as alcohol and tobacco cessation. A careful review of the risk-benefit of the prescribed medication is critical and adaptation may be required in elders with multiple morbidities. Respiratory physiotherapy and mobilization improve the functional status and hence may help reduce the risk of pneumonia. Maintaining teeth and masticatory efficiency is important if malnutrition and its consequences are to be avoided. Daily oral hygiene and regular professional removal of oral biofilm can prevent the onset of periodontitis and can avoid an oral environment favoring the colonization of respiratory pathogens than can then be aspirated into the lungs.

Physical Therapy Management of an Individual With Post-COVID Syndrome: A Case Report

OBJECTIVE

The purpose of this case report is to provide the clinical presentation and physical therapist management for a patient with post-COVID syndrome. Secondarily, the report highlights the importance of assessing cognitive and emotional health in patients with post-COVID syndrome.

METHODS (CASE DESCRIPTION)

A 37-year-old woman tested positive for SARS-CoV-2 and developed mild COVID-19 disease but did not require supplemental oxygen or hospitalization. The patient experienced persistent symptoms, including dyspnea, headaches, and cognitive fog. On day 62, they participated in an outpatient physical therapist evaluation that revealed deficits in exercise capacity, obtaining 50% of their age-predicted 6-minute walk distance. They had minor reductions in muscle strength and cognitive function. Self-reported quality of life was 50, and they scored above established cut-off scores for provisional diagnosis of posttraumatic stress disorder (PTSD).

RESULTS

The patient participated in biweekly physical therapist sessions for 8 weeks, which included aerobic training, strengthening exercises, diaphragmatic breathing techniques, and mindfulness training. Metabolic equivalent for task levels increased with variability over the course of the program. The patient's muscle strength, physical function, and exercise capacity improved. 6-Minute walk distance increased by 199 m, equating to 80% of their age-predicted distance. Quality of life and PTSD scores did not improve. At evaluation after physical therapy, the patient was still experiencing migraines, dyspnea, fatigue, and cognitive dysfunction.

CONCLUSION

This case report described the clinical presentation and physical therapist management of a person with post-COVID syndrome, a novel health condition for which little evidence exists to guide rehabilitation examination and interventions. Physical therapists should consider cognitive function and emotional health in their plan of care for patients with post-COVID syndromes.

IMPACT

This case alerts physical therapists to post-COVID syndrome-which can include debilitating symptoms of decreased aerobic tolerance, anxiety, PTSD, and cognitive dysfunction-and to the role that therapists can play in assessing these symptoms and managing these patients.

Early mobilization and physical exercise in patients with COVID-19: A narrative literature review

BACKGROUND

Currently, little is known about early mobilization and exercise in individuals with COVID-19.

OBJECTIVE

To describe the indication and safety of early mobilization and exercises in mild to severe COVID-19 patients and to investigate the use of telerehabilitation to deliver exercise programs to these patients.

METHODS

This narrative literature review was conducted performing a comprehensive search of databases.

RESULTS

32 articles met the established criteria and the main findings were summarized and described, including indication, contraindication and recommendation for early rehabilitation and exercises prescription.

CONCLUSIONS

The literature suggests that early mobilization and physical exercise are beneficial for individuals with COVID-19. However, much of what has been published is based on expert opinion due to a lack of randomized trials, which are needed.

Practical Recommendations Relevant to the Use of Resistance Training for COVID-19 Survivors

The novel coronavirus disease (COVID-19) has emerged at the end of 2019 and caused a global pandemic. The disease predominantly affects the respiratory system; however, there is evidence that it is a multisystem disease that also impacts the cardiovascular system. Although the long-term consequences of COVID-19 are not well-known, evidence from similar diseases alerts for the possibility of long-term impaired physical function and reduced quality of life, especially in those requiring critical care. Therefore, rehabilitation strategies are needed to improve outcomes in COVID-19 survivors. Among the possible strategies, resistance training (RT) might be particularly interesting, since it has been shown to increase functional capacity both in acute and chronic respiratory conditions and in cardiac patients. The present article aims to propose evidence-based and practical suggestions for RT prescription for people who have been diagnosed with COVID-19 with a special focus on immune, respiratory, and cardiovascular systems. Based on the current literature, we present RT as a possible safe and feasible activity that can be time-efficient and easy to be implemented in different settings.

Variation in Acute Care Rehabilitation and 30-Day Hospital Readmission or Mortality in Adult Patients With Pneumonia

IMPORTANCE

Pneumonia often leads to functional decline during and after hospitalization and is a leading cause of hospital readmissions. Physical and occupational therapists help improve functional mobility and may be of help in this population.

OBJECTIVE

To evaluate whether use of physical and occupational therapy in the acute care hospital is associated with 30-day hospital readmission risk or death.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study included the electronic health records and administrative claims data of 30 746 adults discharged alive with a primary or secondary diagnosis of pneumonia or influenza-related conditions from January 1, 2016, to March 30, 2018. Patients were treated at 12 acute care hospitals in a large health care system in western Pennsylvania. Data for this study were analyzed from September 2019 through March 2020.

EXPOSURES

Number of physical and occupational therapy visits during the acute care stay categorized as none, low (1-3), medium (4-6), or high (>6).

MAIN OUTCOMES AND MEASURES

Outcomes were 30-day hospital readmission or death. Generalized linear mixed models were estimated to examine the association of therapy use and outcomes, controlling for patient demographic and clinical characteristics. Subgroup analyses were conducted for patients older than 65 years, for patients with low functional mobility scores, for patients discharged to the community, and for patients discharged to a post-acute care facility (ie, skilled nursing or inpatient rehabilitation facility).

RESULTS

Of 30 746 patients, 15 507 (50.4%) were men, 26 198 (85.2%) were White individuals, and the mean (SD) age was 67.1 (17.4) years. The 30-day readmission rate was 18.4% (5645 patients), the 30-day death rate was 3.7% (1146 patients), and the rate of either outcome was 19.7% (6066 patients). Relative to no therapy visits, the risk of 30-day readmission or death decreased as therapy visits increased (1-3 visits: odds ratio, 0.98; 95% CI, 0.89-1.08; 4-6 visits: odds ratio, 0.89; 95% CI, 0.79-1.01; >6 visits: odds ratio, 0.86; 95% CI, 0.75-0.98). The association was stronger in the subgroup with low functional mobility and in individuals discharged to a community setting.

CONCLUSIONS AND RELEVANCE

In this study, the number of therapy visits received was inversely associated with the risk of readmission or death. The association was stronger in the subgroups of patients with greater mobility limitations and those discharged to the community.

[Medical rehabilitation of patients with pneumonia associated with the new COVID-19 coronavirus infection]

Effective medical rehabilitation of patients with pneumonia caused by the new SARS-CoV-2 coronavirus is critical for the recovery and optimization of emergency and specialty care outcomes. In this regard, it is relevant to develop a scientifically based medical rehabilitation program for patients with the coronavirus infectious disease COVID-19, whose composition and structure includes methods and tools that have proven effectiveness.

AIM

To develop evidence-based approaches to medical rehabilitation for patients with pneumonia associated with the new COVID-19 coronavirus infection.

RESULTS

The clinical effects and suggested mechanisms of action of rehabilitation technologies in patients with pneumonia, including those associated with the new COVID-19 coronavirus infection, are considered in Detail. The most studied of the physical methods that have a proven effect are physical exercises, breathing exercises, the complex effect of factors of resort therapy, hydrotherapy, which affect the main clinical manifestations of the underlying disease, astheno-neurotic syndrome and increasing immunity. Clinical recommendations for medical rehabilitation are proposed and its promising methods are considered.

CONCLUSION

Regular generalization and analysis of high-quality randomized controlled clinical trials to evaluate various physical methods of treatment of patients with pneumonia associated with the new COVID-19 coronavirus infection is Necessary, which serve as a basis for the development of future valid clinical recommendations. Timely and adequate specialized medical rehabilitation care is critical to maintaining the health, reducing disability and mortality of patients with pneumonia associated with the new COVID-19 coronavirus infection.

The Mediating Effect of Different Exercise Programs on the Immune Profile of Frail Older Women with Cognitive Impairment

Background:

Frail individuals experience an accelerated immunosenescence, and exercise has been identified as a therapy to promote a better inflammatory environment.

Objective:

To analyze the effects of 28-weeks of two different exercise protocols on the functional fitness and immune profiles of institutionalized pre-frail and frail women with mild cognitive impairment.

Methods:

Participants residing in care homes (n=60, 81±7.84 years old) were randomized into three groups: a chair elastic band muscle-strength exercise (CSE, n=21; 81±4.79), a chair multimodal exercise (CME, n=20; 80±8.19), and a control non-exercise (CGne, n=19; 80±10.01). Both CME and CSE groups performed progressive circuit-training exercise sessions. The controls did not change their usual lifestyle. The Fried protocol and the Mini-Mental State Examination questionnaire were used to identify the frail subgroups and the participants with mild cognitive impairment. Data for anti and pro-inflammatory markers and physical fitness were analyzed pre and post-interventions.

Results:

After the intervention, a significant effect of time and time by group for sIgA and time by group for IL- 10 levels were found (p > 0.05). Within-group analysis showed a significant moderate decrease in the TNF-α to IL-10 ratio for the CME group and an increase in the controls (p > 0.05) and a slight reduction in the IL-6 and IL- 1β concentrations. The controls showed a negative trend towards a decrease in physical fitness and a trend for increased levels in the pro-inflammatory markers IL-6 and IL-1β.

Conclusions:

The evidence regarding the use of systematic and moderate long-term exercise as therapy for promoting a better balance between pro- and anti-inflammatory environments and a decrease in the inflammatory index for the CME group were the most promising results from this study.

The Glittre Activities of Daily Living Test in women with scleroderma and its relation to hand function and physical capacity

BACKGROUND

The hands are the primary site of involvement in scleroderma, and impaired hand function is primarily responsible for difficulty in performing activities of daily living. This study aimed to evaluate exercise functional capacity in women with scleroderma through the Glittre Activities of Daily Living Test, which incorporates both lower and upper limb activities, and to correlate the findings with physical capacity and hand function.

METHODS

Thirty-three women with scleroderma and 30 matched control women were assessed with the Glittre Activities of Daily Living Test, the Cochin Hand Functional Scale for hand function, the Scleroderma Health Assessment Questionnaire Disability Index for physical capacity, handgrip strength tests, and pulmonary function tests.

FINDINGS

In the Glittre Activities of Daily Living Test, the median values for total time, manual time, and the manual time/total time ratio were higher among individuals with scleroderma than among controls (P ˂ 0.001 for all tests). Manual time was significantly correlated with the Cochin Hand Functional Scale, the Scleroderma Health Assessment Questionnaire Disability Index, and handgrip strength. Additionally, peripheral oxygen saturation during the Glittre Activities of Daily Living Test was significantly correlated with pulmonary function parameters.

INTERPRETATION

Our results indicate that women with scleroderma need more time to complete the activities in the Glittre Activities of Daily Living Test, largely due to greater difficulty performing the shelves manual task. Thus, the Glittre Activities of Daily Living Test may be used in clinical practice to evaluate the performance of activities of daily living by people with scleroderma.

Exercise training for adults hospitalized with an acute respiratory condition: a systematic scoping review

OBJECTIVE

In adults hospitalized with an acute or chronic respiratory condition, to determine what has been reported regarding exercise programmes in terms of content, tolerability, evaluation and adverse events.

DATA SOURCES

A systematic search was conducted of electronic databases (PubMed, EMBASE, CINAHL, PEDro, The Cochrane Library), trial registries and conference abstracts (Thoracic Society of Australia and New Zealand Annual Scientific Meeting, the European Respiratory Society Congress, the American Thoracic Society International Conference).

REVIEW METHODS

Studies were included if they (1) recruited adults hospitalized with an acute or chronic respiratory condition, (2) described an exercise programme that targeted peripheral muscles and (3) reported that ⩾80% of the sample had initiated training within 72 hours of hospitalization.

RESULTS

The last search was conducted on 2 June 2019. Of the 6282 records identified, 20 met the study criteria. These described 18 separate studies (2018 participants). Studies were conducted in adults hospitalized with an exacerbation of chronic obstructive pulmonary disease or with community-acquired pneumonia. The content of exercise programmes included aerobic and/or resistance training, neuromuscular electrical stimulation, whole-body vibration or movement out of bed. In eight studies (44%), the initial session was prescribed using objective measures of exercise capacity, peripheral muscle force and the ability to undertake activities of daily living. Across 7420 training sessions, seven adverse events were reported.

CONCLUSION

Methods used to prescribe and titrate exercise programmes in adults hospitalized with an acute or an exacerbation of a chronic respiratory condition were disparate. When reported, programmes were well tolerated and adverse events were infrequent.

Patient-reported outcome measurement in community-acquired pneumonia: feasibility of routine application in an elderly hospitalized population

Background

Community-acquired pneumonia (CAP) is a leading cause of morbidity and mortality worldwide, but few studies have evaluated the feasibility of routine patient-reported outcome measures (PROMs) in this illness. This study investigates the feasibility and limitations of three credible PROM instruments in a representative hospitalized cohort to identify potential barriers to routine application.

Methods

A sample of multimorbid hospitalized subjects meeting a standardized CAP definition was recruited. Demographic and clinical data of those able and unable to participate in PROM assessment were compared. The EQ-5D-5L, CAP-Sym 18 Questionnaire, and Late-Life Function and Disability Instrument (LLFDI) were administered (via face-to-face interview) at admission and discharge and (via phone interview or mail) at 30 and 90 days post-discharge. Feasibility measures included the proportion of individuals able to participate in assessment, attrition rates, data completeness, and instrument completion times. Scores at admission and 30 days post-discharge were examined for association with age.

Results

Of 82 subjects screened, 44 (54%) participated. Cognitive impairment (n = 12, 15%) commonly precluded participation. Seventeen (39%) participants were lost to follow-up by 90 days. Missing data at item level was negligible for all instruments, regardless of the mode of completion. Completion of the three instruments collectively in a face-to-face interview took a median of 17 min (IQ range 13-21) per participant. The burden of reported symptoms at admission was higher for younger participants aged 18-74 years (mean (standard deviation)) CAP-Sym 18 score at admission 34.2 (18.6) vs. 19.0 (11.3) for those aged ≥ 75 years.

Conclusions

Routine application of PROMs can provide valuable information relating to multiple aspects of clinical recovery for individuals hospitalized with CAP. However, heterogeneous demographic characteristics and complex underlying health status introduce challenges to feasibility and interpretability of these instruments in this population.

Respiratory muscles dysfunction and respiratory diseases

This review presents an analysis of the literature on the topic of respiratory muscle (RM) dysfunction in various forms of respiratory pathology: chronic obstructive pulmonary disease (COPD), asthma, community-acquired pneumonia, idiopathic pulmonary fibrosis (IPF), sarcoidosis and interstitial lung diseases (ILD), associated with systemic connective tissue diseases (polymyositis, dermatomyositis and systemic lupus erythematosus - SLE). Various clinical and pathophysiological aspects of RM dysfunction and general patterns of its pathogenesis were examined. It was proved that the role of RM in the development of respiratory failure depends on the form and stage of the pulmonary pathology and the severity of systemic manifestations of these diseases: excessive proteolysis, oxidative stress, hypoxia, chronic systemic inflammation. These factors modify the morphofunctional status of RM, worsens their contractile function, which is contributed to the development of respiratory failure. In some cases, the primary weakness of RM precedes the clinical manifestation of pulmonary pathology, which is distinctive for some variants of myositis-associated ILD and SLE. Endogenous intoxication syndrome plays a significant role in the development of RM dysfunction during community-acquired pneumonia. It is noted that sarcoid pulmonary ventilation disorders associate with the RM weakness, but not with the degree of lung damage. In most cases, secondary RM dysfunction predominates that contributes to respiratory failure progression, which is especially noticeable in case of COPD, asthma and IPF.

Does adding an integrated physical therapy and neuromuscular electrical stimulation therapy to standard rehabilitation improve functional outcome in elderly patients with pneumonia? A randomised controlled trial

OBJECTIVE

To compare the effects of an integrated programme of physical and electrical therapy to standard rehabilitation to improve physical and functional performance in elderly patients with pneumonia.

DESIGN

Randomized clinical trial. The study was registered in the ClinicalTrial.gov website (identifier: NCT02515565).

SETTING

University Hospital.

SUBJECTS

In total, 185 elderly patients with pneumonia were eligible for the study, of which 95 were finally randomized.

INTERVENTIONS

Patients were randomized to a control group which received the standard treatment or to an intervention group which received additionally an integrated programme of physical and electrical therapy.

MAIN MEASURES

Demographic and clinical information was acquired. Pulmonary function, length of hospital stay, handgrip strength, independence levels and comorbidities were assessed as descriptive outcomes. The main outcome measure was functional and physical performance, evaluated with the short physical performance battery. Secondary outcome measures were respiratory symptoms including dyspnoea, fatigue and cough.

RESULTS

Mean age of patients was 74.92 (11.03) years in the intervention group and 72.53 (9.24) years in the control group. Significant between groups differences (P < 0.05) were found in short physical performance battery chair stand test (2.17 (0.97) vs. 0.58 (0.61)) and total score (5.91 (3.61) vs. 4.15 (3.15)). The intervention group showed better performance than the control group in both cases. Fatigue (32.04 (18.58) vs. 46.22 (8.90)) and cough (18.84 (2.47) vs. 17.40 (3.67)) showed higher improvement in the intervention group, and significant differences were observed between the groups.

CONCLUSION

An integrated programme of physical and electrical therapy during hospitalization improves physical and functional performance in patients with pneumonia.

Effect of Early Mobility as a Physiotherapy Treatment for Pneumonia: A Systematic Review and Meta-Analysis

Purpose: We conducted a systematic review of the effect of early mobility on length of stay (LOS), mortality, and clinical outcomes as a treatment for adults hospitalized with pneumonia. Method: An electronic search of four databases was conducted. Inclusion criteria were (1) acute medical condition of pneumonia in adults and (2) early mobility intervention. Quality appraisal was conducted using the Physiotherapy Evidence Database scale and the Newcastle-Ottawa Scale. Results: Four studies (three randomized controlled trials and one retrospective cohort study) met the inclusion criteria. Meta-analysis demonstrated that early mobility did not reduce the risk of mortality compared with usual care (risk ratio 0.9 [95% CI: 0.27, 2.97]; p = 0.86) but did reduce the mean LOS (-1.1 days [95% CI: 2.21, -0.04]; p = 0.04). Early mobility also did not affect the rate of hospital readmissions or emergency department visits. One study demonstrated an improvement in functional exercise capacity and quality of life related to physical function and faster completion of a measure of activities of daily living. Conclusions: Early mobility reduced LOS in adults hospitalized with community-acquired pneumonia, although there was no effect on mortality or rate of hospital readmissions. Further research is needed to determine the effect of early mobility in this population and establish guidelines.

Change in skeletal muscle associated with unplanned hospital admissions in adult patients: A systematic review and meta-analysis

OBJECTIVES

The primary objective of the review was to describe change that occurs in skeletal muscle during periods of unplanned hospitalisation in adult patients. The secondary objective was to examine the relationship between both physical activity and inflammation with the change in skeletal muscle. A further objective was to investigate the effect of interventions on change in skeletal muscle during periods of unplanned hospitalisation.

DESIGN

A systematic review and meta-analyses. Embase, MEDLINE, CINAHL, AMED, PEDro and the Cochrane Library were searched for studies that included any measures of skeletal muscle (excluding pulmonary function) at two time points during unplanned hospitalisation. Studies that were set in critical care, or included patients with acute or progressive neurological illness, were excluded.

RESULTS

Our search returned 27,809 unique articles, of which 35 met the inclusion criteria. Meta-analyses of change between baseline and follow-up in random effects models suggested that grip strength had an average increase: standardised mean difference (SMD) = 0.10 (95% CI: 0.03; 0.16); knee extension strength had an average reduction: SMD = -0.24 (95% CI: -0.33; -0.14); and mid-arm muscle circumference had an average reduction: SMD = -0.17 (95% CI: -0.22; -0.11). Inflammation appeared to be associated with greater loss of muscle strength. There was inconclusive evidence that the level of physical activity affects change in skeletal muscle. In regard to the effect of interventions, only exercise interventions were consistently associated with improved skeletal muscle outcomes.

CONCLUSIONS

Adult patients who undergo an unplanned hospital admission may experience a small reduction in knee extension strength and mid-arm muscle mass. Prospective research is needed to clarify the contribution of confounding factors underlying the observations made in this review, with particular attention to levels of physical activity, and possible contributions from environmental factors and processes of hospital care.

Positive Effects of a Short-Term Intense Elastic Resistance Training Program on Body Composition and Physical Functioning in Overweight Older Women

The aim of this study was to investigate the effects of a resistance training program (RTP) in older overweight women (OOW) using two different types of elastic devices.

METHODS

This study was a randomized controlled trial with pre- and postintervention measures. Participants included OOW, aged 60-85 years, with no medical history of disease that would preclude them from engaging in physical exercise. Participants were randomly divided into the following groups: elastic tubes with handles group (ETG; n = 22), traditional elastic bands group ( n = 21), and control group (CG; n = 20). Exercise groups (EGs) performed the following supervised RTP: 8 weeks, twice weekly, six overall body exercises, and 3-4 sets of 10 repetitions at a rate of perceived exertion (RPE) of 7-9 on the OMNI-Resistance Exercise Scale of perceived exertion. The controls did not change their usual lifestyle. Outcome measures included body composition (BC; total and regional percentage of fat mass [FM] and fat-free mass [FFM]) and physical performance (PP; dynamic and isometric strength, flexibility, agility/dynamic balance, and endurance).

RESULTS

Both EGs exhibited significantly reduced FM in the upper limbs (ULs) and trunk and increased FFM in the UL, while the ETG exhibited a significantly increased trunk FFM. Both EGs improved in PP, and there were no intergroup differences. Trunk FM and FFM and meters walked differed significantly between the ETG and CG. The CG did not exhibit any significant changes.

CONCLUSION

Training with elastic devices at a moderate-high RPE produces short-term improvements in BC and PP in OOW.

Concurrent validation of the OMNI-Resistance Exercise Scale of perceived exertion with elastic bands in the elderly

PURPOSE

To examine the concurrent validity of the OMNI-Resistance Exercise Scale of perceived exertion using elastic bands in elder population.

METHODS

Twenty-six participants performed three separate sets of 15 repetitions (low- medium- and high-intensity) for 4 different exercises (2 for the upper-limb and 2 for the lower limb), over two different testing sessions. The criterion variables were heart rate and applied force (average and maximum). In addition to these dependent variables, the active muscle and overall body OMNI-RES for elastic bands scores were collected at the end of each repetition.

RESULTS

Significant differences in heart rate, applied force and OMNI-RES scores between the low- and high-intensity sets were observed. For all the four exercises, high intensity sets elicited higher heart rate, applied force, and RPE compared to the medium and the low overloads. Intraclass correlation coefficient was 0.79 in heart rate and ranged 0.69-0.80 in OMNI-RES Scale and 0.76-0.86 for the applied force.

CONCLUSION

A strong positive and linear relationship was observed between the rating of perceived exertion and both heart rate and applied force. The OMNI-RES scale with elastic bands demonstrated to be a valid method for assessing the perceived exertion during resistance exercises and consequently represent a useful tool for prescribing exercise intensity to the elderly.

Metabolic and Functional Profile of Premenopausal Women With Metabolic Syndrome After Training With Elastics as Compared to Free Weights

The aim of this study was to compare the effects of a strength training program (STP) using free weights (FW) versus elastic tubing (ET) in 62 premenopausal, sedentary women diagnosed with metabolic syndrome (MS). Participants were randomly assigned to the FW or ET experimental group (EG) or a control group whose members remained sedentary. Members of each EG followed their assigned STP for 12 weeks, and biomarkers (BMs) related to MS and motor function (MF) parameters were evaluated. Both EGs showed a significant reduction in C-reactive protein level and a positive trend in the other BMs. Almost all MF parameters increased significantly in both EGs. No positive changes were found in the CG. These results indicate that the implementation of an STP, with either FW or ET, improves both metabolic health and MF and should be considered part of the basic approach to health care in women.
