What is most appropriate number of repetitions of the sit-to-stand test in older adults: a reliability study

Test-retest reliability of Latin American Group for Maturity (GDLAM) protocol in older women

Functional autonomy (FA) is a critical factor in determining the quality of life of older adults (OA), especially in the case of older women (OW), as they face a decline in FA in their later years of life. FA should be assessed early, using valid, reliable, and low-cost tests. This study evaluated the test-retest reliability of GDLAM and GDLAM autonomy index (GI) in OW. Thirty-nine OW (71.2 ± 6.50 years) participated in the study. A repeated measures design was used to compare the interday test-retest reliability of the five GDLAM tests (seconds) and the GI (points). The five tests represent activities of daily living, such as dressing or wandering around the house, while the GI provides a weighting of the results of the five tests. The analysis consisted of the intraclass correlation coefficient (ICC), standard error of measurement (SEM), and coefficient of variation (CV). A CV ≤ 10% and an ICC ≥ 0.80 were considered acceptable reliability, whereas a CV ≤ 5% and an ICC ≥ 0.90 were considered high reliability. The outcome of the five tests, represented by the GI, showed high interday test-retest reliability (CV = 6.00% and ICC = 0.91). The results of this study demonstrate that the five tests of the GDLAM protocol and the GI have high interday test-retest reliability and good interday reproducibility. From a practical point of view, the GDLAM protocol allows the assessment of FA of community-dwelling OW, providing background for early diagnosis and, with it, the possibility of developing an individualized physical exercise prescription.

Women with fibromyalgia (ACR criteria) compared with women diagnosed by doctors and women with osteoarthritis: Cross-sectional study using functional and clinical variables

PURPOSE

To compare functional and clinical variables of women with fibromyalgia (American College of Rheumatology [ACR] criteria) vs women diagnosed by doctors and women with knee osteoarthritis (KOA).

METHODS

This is a cross-sectional study. We used clinical measures, namely, Widespread Pain Index (WPI), Symptom Severity Scale (SSS), Fibromyalgia Impact Questionnaire-Revised (FIQ-R), Numerical Pain Rating Scale (NPRS), Central Sensitization Inventory (CSI), Pain-Related Catastrophizing Thoughts Scale (PCTS), and functional measures, such as Sit-to-Stand (STS) test, and Timed Up and Go (TUG) test.

RESULTS

The sample consisted of 91 participants divided into 3 groups: participants with KOA (n = 30), fibromyalgia diagnosed according to the ACR (FM-ACR, n = 31), and fibromyalgia according to the medical diagnosis (FM-Med, n = 30). In the comparisons, we observed a significant difference (P < 0.05) and a large effect size (d ≥ 0.8), between all groups, in the WPI, WPI + SSS, FIQ-R domains, CSI, and PCTS. We did not observe significant values in the correlations between the clinical variables, SST, and TUG test.

CONCLUSION

People with fibromyalgia according, to the ACR, have higher levels of widespread pain, symptom severity, global impact on quality of life, central sensitization, and catastrophizing compared with people with knee OA and people with clinical fibromyalgia diagnosis not confirmed by the ACR diagnostic criteria.

The reliability and agreement of scores in a novel balance measure for older adults: Specific Training According to BaLance Evaluation (STABLE)

PURPOSE

Falls are the leading cause of injury and premature death among community dwelling elderly but can be prevented through comprehensive balance rehabilitation which ideally targets the patient's specific needs. In this study, we evaluate the reliability and agreement of six novel clinical measures of different balance domains which applied in a patient-specific balance profile guides exercise prescription in balance rehabilitation.

MATERIALS AND METHODS

The intra-rater reliability and agreement of the six measures were evaluated on the same day in six different cohorts of elderly with balance disability (n = 65-100). Further, the inter-day intra-rater and inter-rater and test-retest reliability and agreement of the measures and the balance profile were evaluated (n = 100).

RESULTS

The intra-day intra-rater reliability and agreement was moderate to excellent (ICC2.1 = 0.525-0.968, with SDC% = 6.5-284.9%) but poor to good for the inter-day conditions (ICC2.1 = 0.123-0.832, with SDC% = 6.6-229.2%). The reliability of classifying the lower domain in the balance profile was fair, with kappa = 0.56 (95%CI 0.36-0.76).

CONCLUSIONS

Five of the six measures may reliably be applied to measure balance disability and to guide rehabilitation.

Implications for rehabilitationBalance disability is the primary reason for accidental falls among elderly but can be prevented through comprehensive individualized balance rehabilitation.Specific Training According to BaLance Evaluation (STABLE) is a novel approach for designing effective balance exercises based on clinical measurements.Five of the six measures are reliable when applied in a patient-specific balance profile to guide rehabilitation following the STABLE approach.

Changes in Functional Outcomes After an Inpatient Rehabilitation Program for Solid-Organ Transplant Recipients

Introduction: Outpatient exercise training has been shown to be beneficial for solid organ transplant recipients. Little is known about the effects of inpatient rehabilitation programs for recipients with a more complicated postoperative course. Research Question: This study was designed to (1) describe the changes in functional outcomes after an inpatient rehabilitation program, and (2) determine whether the changes in lower body strength and quadriceps strength are associated with changes in functional exercise capacity. Design: This was a single-arm prospective longitudinal study. The recipients participated in an inpatient rehabilitation program twice a day, 7 days a week for 3 to 4 weeks. Outcome Measures Included: 2-Minute Walking Test, Timed Up and Go, Berg Balance Scale, 30-Second Sit to Stand, biceps and quadriceps strength, Functional Independence Measure, SF-36, and Canadian Occupational Performance Measure. Results: Twenty-eight patients (54% female, mean age = 55 [11]) completed the study. Participants were mostly liver (42%) and lung recipients (35%). There were statistically significant improvements in all outcomes after the intervention. There was no relationship between changes in functional exercise capacity and quadriceps strength or lower body strength. Conclusion: An inpatient rehabilitation program may improve several functional outcomes and health-related quality of life in transplant recipients with a complicated postoperative course.

REAC Neurobiological Modulation as a Precision Medicine Treatment for Fibromyalgia

Fibromyalgia syndrome (FS) is a disorder characterized by widespread musculoskeletal pain and psychopathological symptoms, often associated with central pain modulation failure and dysfunctional adaptive responses to environmental stress. The Radio Electric Asymmetric Conveyer (REAC) technology is a neuromodulation technology. The aim of this study was to evaluate the effects of some REAC treatments on psychomotor responses and quality of life in 37 patients with FS. Tests were conducted before and after a single session of Neuro Postural Optimization and after a cycle of 18 sessions of Neuro Psycho Physical Optimization (NPPO), using evaluation of the functional dysmetria (FD) phenomenon, Sitting and Standing (SS), Time Up and Go (TUG) tests for motor evaluation, Fibromyalgia Impact Questionnaire (FIQ) for quality of life. The data were statistically analyzed, and the results showed a statistically significant improvement in motor response and quality of life parameters, including pain, as well as reduced FD measures in all participants. The study concludes that the neurobiological balance established by the REAC therapeutic protocols NPO and NPPO improved the dysfunctional adaptive state caused by environmental and exposomal stress in FS patients, leading to an improvement in psychomotor responses and quality of life. The findings suggest that REAC treatments could be an effective approach for FS patients, reducing the excessive use of analgesic drugs and improving daily activities.

How much time in sedentary behavior is associated with probable sarcopenia in older adults?

Sedentary activities, such as watching television and using the computer, are frequent conditions in older adults and can be associated with sarcopenia. The objectives of this study were: (a) to establish sedentary behavior (SB) cutoff values for screening probable sarcopenia in community-dwelling older adults and (b) to verify the association between SB and probable sarcopenia according to the established cutoff point. This was a cross-sectional study including 1,165 community residents in Florianopolis/SC. SB was assessed using the International Physical Activity Questionnaire. The outcome was probable sarcopenia (assessed by time ≥ 15 s in the Five times sit-to-stand test). The cut-off points found for SB were time > 120 min/day [AUC: 0.54 (95%CI: 0.51; 0.57)] watching TV or video/DVD and ≤ 20 min/day [AUC: 0.59 (95%CI: 0.56;0.62)] using computer/internet. Older adults with SB had 1.30 (95% CI: 1.01; 1.66) and 1.46 (95% CI: 1.08; 1.96) greater chances of having sarcopenia, respectively.

The Effects of a Home-Based Combined Motor Control and Ergonomic Program on Functional Ability and Fear of Falling: A Randomized Controlled Trial

Objectives Physical exercise is a key intervention for improving functional ability and preventing falls in older people. However, the implemented interventions targeted balance, gait, and muscle strength, while little is known regarding motor control exercises in this population. Therefore, this study aimed to investigate the effects of a 12-week home-based motor control exercise program combined with an ergonomic home modification (the McHeELP program). Patients and methods Fifty-two older people (aged ≥65 years), who had experienced at least one fall incident in the past 12 months, were randomly assigned into two groups; the McHeELP group (McHeELP-G) (n=26) that received the McHeELP program and the control group (CG) (n=26). Physical performance measures (PPMs) and patient-reported outcomes (PROs) were used to evaluate participants. At baseline, 3rd month (post-intervention), and again at 6th month (follow up), balance control was assessed using the Tandem stance test (Tandem) and the Functional Reach Test (FRT). Functionality was assessed by the 4 meters walking test (4MWT), Timed Up and Go (TUG) test, 30 seconds-Sit to stand test and the Greek version of Lower Extremity Functional Scale (LEFS-Greek). The Greek version of the Falls Self-efficacy International scale (FES-I_GREEK) was used for the evaluation of "fear-of-falling" (FOF). The home falls and accidents screening tool (HOMEFAST) is used to identify home hazards. Two-way mixed ANOVA model, independent samples t-test, One-factor Repeated Measures ANOVA model and ANCOVA model were used for the statistical analysis of the data. Results Homogeneity was found between McHeELP-G and CG regarding the demographic and clinical characteristics, and no statistically significant difference was found at baseline measurements of PROs and PPMs, except HOMEFAST (p=0.031). Post-intervention (3rd month), the comparison of the absolute values between groups revealed that the McHeELP-G achieved statistically significant better balance control (longer Tandem stance test and higher values of FRT), better functionality [faster gait speed (4MWT), shorter TUG performance time, and a higher number of repetitions at 30 seconds-Sit to stand] (all p-values <0.05), while no difference was found for LEFS-Greek score (p=0.095), compared to CG. In addition, McHeELP-G reported lesser FOF than CG [lower FES-I_GREEK score (p=0.041)], and fewer home-hazards [lower HOMEFAST score (p=0.041)]. At follow up measurement (6th month), all PPMs scores of McHeELP-G, regarding balance control and functionality, were remained statistically significant (all p-values <0.005), and the FES-I_GREEK score (p=0.034), while no difference was found between groups for LEFS-Greek score (p=0.146) and HOMEFAST score (p=0.185). Sensitivity analysis (from baseline to 3rd and 6th month) revealed similar findings to the "comparison of the absolute values between groups" analysis. The within-group changes from baseline to 3rd month of McHeELP-G were statistically significant improved for all PPMs and PROs (all p-values <0.05), while in CG, statistical significant difference was found for TUG, FRT-right, and HOMEFAST (p<0.05). Those within-group changes were also preserved until 6th month. Conclusions The study's findings provide encouraging evidence that McHeELP program may increase functional ability and decrease FOF of older people. However, further research is required for a thorough understanding of the effect of McHeELP program.

Methodology of a home-based motor control exercise and ergonomic intervention programme for community-dwelling older people: The McHeELP study

The aim of this research (Motor control Home ergonomics Elderlies' Prevention of falls; McHeELP study) was to develop a novel intervention combining motor control home-based exercises and a home ergonomic safety-improvement strategy in order to reduce falls in frail ambulatory older adults. A randomized controlled trial of a novel intervention is proposed including motor control exercises and home ergonomic assessment and modification in older adults who have at least one fall experience. Participants are randomized to control or intervention group in a 1:1 ratio. Participants will be assessed three times: at baseline, at 3rd month (end of intervention period) and again at 6th month (follow-up measurement). The primary outcome is of the effect on functional mobility using the Timed Up and Go test. Secondary outcomes include assessments of functionality, fear of falling and quality of life. This will be the first study to develop an exercise intervention approach that combines home-based motor control exercise intervention with home assessment and modification. This study is expected to explore a low-cost, easy-to-popularize, and effective exercise intervention approach for improving functional mobility and prevent falls among older adults.

Cognitive and behavioral factors associated to probable sarcopenia in community-dwelling older adults

Background: Sarcopenia has a high prevalence in older adults and is associated with chronic aggravations to health, so therefore it is important to identify older adults who are affected by sarcopenia in order to establish preventative strategies or early interventions.Objective: To estimate the prevalence of probable sarcopenia and verify its association with cognitive impairment, fear of falling, depressive symptoms and health self-perception in community-dwelling older adults.Methods: A cross-sectional study with simple random sampling including 306 older adults of both genders. The outcome variable was probable sarcopenia evaluated by the Five times sit-to-stand test (5XSST) considering probable sarcopenia when the measured time was > 15 seconds, following the recommendation of the European Working Group on Sarcopenia in Older People. The predictor variables were cognitive impairment, fear of falling, depressive symptoms and self-perception of health. Multivariate Logistic Regression was performed to verify associations between the variables.Results: The prevalence of probable sarcopenia was 50.00%. The older adults had significantly higher chances of presenting probable sarcopenia when displaying cognitive impairment (OR 2.49; 95%CI 1.46-4.24), fear of falls (OR 4.23; 95%CI 2.51-7.12), depressive symptoms (OR 2.20; 95%CI 1.32-3.67), poor (OR 2.48; 95%CI 1.19-5.16) and fair self-perception of health (OR 2.11; 95%CI 1.22-3.63) when compared to those who did not have the same conditions.Conclusion: The prevalence of probable sarcopenia in this study was 50.00%, and was associated with the presence of depressive symptoms, cognitive impairment, fear of falls and negative self-perception of health.

Motor Control and Ergonomic Intervention Home-Based Program: A Pilot Trial Performed in the Framework of the Motor Control Home Ergonomics Elderlies' Prevention of Falls (McHeELP) Project

Objectives Falls are a serious problem that can reduce living autonomy and health-related quality of life of older adults. A decrease in the muscular strength of the lower limbs and the deterioration of balance or motor performance deficits may lead to falls. "Motor Control Home Ergonomics Elderlies' Prevention of Falls" (McHeELP) is a novel motor control exercise program combined with ergonomic arrangements of the home environment. This pilot trial is conducted in order to examine the feasibility and acceptability of the McHeELP program, the selection of the most appropriate outcome measures, and the exact sample size calculation that should be used for the randomized controlled trial (RCT) with Clinical Trial Identifier: ISRCTN15936467. Patients and methods Twenty older adults (aged ≥65 years) who had experienced at least one fall-incident in the past 12 months have participated in the trial; they were randomized in a 1:1 ratio to the McHeELP group (McHeELP-G) and the Control group (CG). The McHeELP-G received a personalized therapeutic motor control and learning exercise program performed three times per week for 12 weeks. Regarding McHeELP - home modification, a booklet that contained basic advice and tips on the modification for their inside and outside home environment was provided to the participants. Objective and self-reported outcome measures, collected at baseline and post-intervention (end of the third month), included functional, fear of falling, and quality of life measurements. Results The McHeELP intervention was very feasible and acceptable to the participants, and the adherence was excellent (100%). The majority of outcome measures seemed appropriate and significant differences were also revealed between the two groups. Specifically, post-intervention statistically significant improvement was found in the 4 meters walking test, Timed Up and Go test, Sit to Stand test, Tandem Stance test, Functional Reach test, Foot tapping test, EuroQoL-5D-5L - visual analog scale (VAS), Lower Extremity Functional Scale, Falls Self-Efficacy International Scale, and Home Falls and Accidents Screening Tool (HOMEFAST) questionnaire of McHeELP-G (all p-values ≤0.002). No statistically significant difference was observed in the mobility, self-care, usual activities, pain/discomfort subscales of Euro QoL-5D-5L (all p-values >0.05), except the anxiety/depression subscale of McHeELP-G (p=0.008). Moreover, no statistically significant improvement was found regarding McHeELP participants' knee flexion/extension restriction and ankle dorsiflexion/plantar-flexion restrictions. Regarding CG, no statistically significant difference was found (p>0.05), except the Tandem Stance test (p=0.003) and HOMEFAST (p<0.001). Referring to the future McHeELP RCT, it was estimated that a sample size of 25 evaluable patients per group is required. Conclusions This pilot trial's findings suggest that it is feasible to deliver an RCT of the McHeLP program to this population. Exercise programs that are easy to administer need to be developed and implemented to reduce the burden of falls in older adults.
