Effect of Home Exercise Training in Patients with Nonspecific Low-Back Pain: A Systematic Review and Meta-Analysis

How Do Physical Therapists and Athletic Trainers Maintain Their Physical Fitness? A Descriptive Survey Study

Background

Physical therapists and athletic trainers play an important role in promoting physical activity to patients and may utilize the 2018 United States Physical Activity Guidelines (PAG). Currently, there is little data regarding how physical therapists and athletic trainers maintain their personal fitness based upon these guidelines.

Purpose

To analyze how physical therapists and athletic trainers maintain their physical fitness based upon the 2018 United States Physical Activity Guidelines.

Study Design

Cross-sectional descriptive survey.

Methods

A 20-question electronic survey was emailed to members of the Academy of Orthopedic Physical Therapy and National Athletic Trainers Association. Professionals were also informed through a recruitment post in different private healthcare Facebook® groups. Survey inclusion criteria included respondents being a physical therapist or athletic trainer and being in clinical practice. Respondents were excluded if they did not meet the inclusions. The 2018 PAG were used as a minimum standard comparison for respondents to report their physical activity. The survey was developed using Qualtrics and underwent two rounds of pilot testing to establish face validity. The survey covered respondent demographics, exercise behaviors, reasons for exercise, exercise programming and assessment, exercise barriers, monitoring health & wellness, and respondent satisfaction with how they have maintained their own physical fitness. Descriptive statistics were used to calculate total responses, frequency count, and percentages.

Results

One thousand one hundred and forty seven professionals (Women =58%, N= 665; Men = 41%, N=472; other = 1%, N=10) (mean age = 48 ± 15.75 years-old) completed the survey. Most respondents (~ 82%) reported meeting or exceeding the PAG for aerobic and muscle-strengthening while using an integrated exercise approach with self-guided workouts (73%) in different settings such as home (65%) or fitness facility (30%). Respondents dedicated an average of 14 hours per week to exercise. A smaller portion of respondents did not meet the PAG and reported displeasure with their current fitness program which may be related to different exercise barriers such as work schedule, lack of time, family commitments, low intrinsic motivation, and lack of energy.

Conclusion

These survey results provide insight into how physical therapists and athletic trainers maintain their physical fitness. The majority of respondents demonstrated good exercise behaviors by exceeding or meeting the 2018 PAG while a smaller portion did not meet the guidelines due to various exercise barriers and displeasure. Future research should investigate strategies to help professionals find optimal work-life balance and time for weekly physical activity.

Physical activity and factors associated with the costs of low back pain among adults after 18 months of follow-up: a cohort study

BACKGROUND

Chronic low back pain (CLBP) is a substantial health problem that causes considerable economic losses. Several studies have demonstrated the protective effect of habitual physical activity; however, little data are available regarding its impact on the costs associated with CLBP.

OBJECTIVES

The primary aim of this study was to analyze the costs of CLBP in the Brazilian Health System and associated factors among adults.

DESIGN AND SETTING

An 18-month cohort study was conducted in two basic health units in Presidente Prudente (SP), Brazil.

METHODS

A total of 198 patients were interviewed and evaluated four times: at baseline, with retrospective data covering the previous 12 months, and at six, 12, and 18 months. The Nordic and Baecke questionnaires were used to classify CLBP, and the Baecke questionnaire was used for physical activity assessment. The costs were calculated by reviewing the demand for services from medical records. Body mass index (kg/m2) was determined using body mass and height values collected during the interviews. The questionnaire included confounding variables, such as sex, age, ethnicity, and socioeconomic status.

RESULTS

A high prevalence of CLBP was observed, which was associated with female sex and younger age. CLBP resulted in high costs for medical consultations (without: US$ 34.25 ± 23.21; with: US$ 39.62 ± 27.25; P = 0.049), while cycling was negatively associated with costs (rho = -0.289; P = 0.049).

CONCLUSION

Lower back pain was associated with higher costs of medical consultations, while cycling was associated with reduced costs.

Effects of a Postural Hammock in People with Chronic Neck Pain and Chronic Low Back Pain: A Randomized Controlled Trial

Background and Objectives: Musculoskeletal disorders (MD) affect over 1.7 billion people worldwide, with neck and low back pain being prevalent and debilitating conditions. Current treatments include various interventions, but novel approaches are needed to improve functionality and reduce disability. To evaluate the effects of a postural hammock on pain and functionality in people with chronic neck and low back pain. Materials and Methods: A randomized controlled trial was conducted with participants experiencing chronic neck and/or low back pain. They were assigned to either an experimental group using a postural hammock or a control group lying on a mat. Participants underwent five sessions of 10 min each over five consecutive days. Results: Forty-three subjects completed the study. While both groups showed improvements, the experimental group exhibited significant increases in hamstring flexibility and pain tolerance, measured through the Visual Analog Scale (VAS) and pressure pain thresholds (PPT). Postural hammock use demonstrated potential benefits in pain management and flexibility compared to conventional methods. Conclusions: Using a postural hammock may offer benefits for individuals with chronic back pain. Future research should explore combining hammock therapy with other interventions to enhance outcomes and improve the quality of life for patients with back pain.

Gamified delivery of at-home rehabilitation for individuals with nonspecific low back pain: a randomized controlled trial

PURPOSE

To measure the change in pain and disability during and after a 6-week gamified delivery of home exercise compared to a take-home packet.

MATERIALS AND METHODS

A 6-week at-home exercise protocol included participants randomly allocated to a gamified delivery group or packet group. The exercise protocol included the plank, side plank, foot elevated side plank, dead bug, and bird dog completed until discontinuation. The gamified delivery group received on-demand exercise videos and weekly exercise duration leaderboards. The packet group received a take-home packet.

RESULTS

Forty participants were randomized into a packet group and leaderboard group, and 30 participants completed the study. Disability was significantly lower at 6-weeks (11.29 ± 9.81%) compared to baseline (15.93 ± 11.65%) in the packet group (χ2(2) =10.89, Z= -3.163, p=.002, r=.708). Percent disability was significantly lower at 6-weeks (8.00 ± 5.91%) compared to baseline (13.01 ± 7.17%) in the gamified delivery group (χ2(2) =13.235, Z= -3.399, p= <.001, r= -0.760). Worst pain was higher at baseline (7.05 ± 1.61%) than at 6-weeks (5.75 ± 1.68%) in the packet group (χ2(2) =8.067, Z = 2.760, p=.006, r= -0.617). Worst pain was higher at baseline (6.90 ± 1.33%) than at 6-weeks (5.24 ± 2.38%) in the gamified delivery group (χ2(2) =6.250, Z= -2.810, p=.005, r= -0.628). No significant difference in the change of disability from baseline to 6 weeks was found between groups (p=.483).

CONCLUSIONS

Core exercises completed until failure may improve disability and pain at 6-weeks and positively influence perceived patient improvement.Registry: Clinicaltrials.gov; Registration number: NCT05573932.

Exploring the Effect of an 8-Week AI-Composed Exercise Program on Pain Intensity and Well-Being in Patients With Spinal Pain: Retrospective Cohort Analysis

Background

Spinal pain, one of the most common musculoskeletal disorders (MSDs), significantly impacts the quality of life due to chronic pain and disability. Physical activity has shown promise in managing spinal pain, although optimizing adherence to exercise remains a challenge. The digital development of artificial intelligence (AI)-driven applications offers a possibility for guiding and supporting patients with MSDs in their daily lives.

Objective

The trial aimed to investigate the effect of an 8-week AI-composed exercise program on pain intensity and well-being in patients with spinal pain. It also examined the relationship between exercise frequency, pain intensity, and well-being. In addition, app usage frequency was examined as a proxy for app engagement.

Methods

Data from users who met the inclusion criteria were collected retrospectively from the medicalmotion app between January 1, 2020, and June 30, 2023. The intervention involved the use of the medicalmotion app, which provides 3-5 personalized exercises for each session based on individual user data. The primary outcomes assessed pain intensity and well-being using the numeric rating scale (NRS) and the Likert scale. Data were collected at baseline (t0), 4 weeks (t1), and 8 weeks (t2). The correlation between exercise frequency, pain intensity, and well-being was analyzed as a secondary outcome. In addition, average session length and frequency were measured to determine app engagement. Statistical analysis included ANOVA and Spearman correlation analysis.

Results

The study included 379 participants with a mean age of 50.96 (SD 12.22) years. At t2, there was a significant reduction of 1.78 points on the NRS (P<.001). The score on the Likert scale for well-being improved by 3.11 points after 8 weeks. Pain intensity showed a negative correlation with the number of daily exercises performed at t1 and t2. Well-being had a small negative correlation with the average number of exercises performed per day. The average number of exercises performed per day was 3.58. The average session length was approximately 10 minutes, and the average interaction with the app was 49.2% (n=27.6 days) of the 56 available days.

Conclusions

Overall, the study demonstrates that an app-based intervention program can substantially reduce pain intensity and increase well-being in patients with spinal pain. This retrospective study showed that an app that digitizes multidisciplinary rehabilitation for the self-management of spinal pain significantly reduced user-reported pain intensity in a preselected population of app users.

Short-term effects of exergaming on patients with chronic low back pain: A single-blind randomized controlled trial

BACKGROUND

Exergaming is increasingly popular, but its impact on chronic low back pain (CLBP) remain unclear.

OBJECTIVES

To evaluate the effectiveness of exergaming versus traditional exercise for managing CLBP using the International Classification of Functioning, Disability and Health (ICF) framework.

METHODS

This single-blind, randomized controlled trial included 70 participants with CLBP, who were assigned to either the exergaming or traditional exercise group. Both groups received 2 weeks of treatment with six sessions. Assessments included the Oswestry Disability Index (ODI), range of motion, Hospital Anxiety and Depression Scale (HADS), balance (Biodex Stability System), Fear-Avoidance Beliefs Questionnaire (FABQ), and physical performance tests.

RESULTS

After six sessions over 2 weeks, the exergaming group showed significant improvements over the exercise group in ODI (p < 0.001), chair-rising time (p = 0.001), stair ascent (p = 0.025) and descent times (p < 0.001), flexion (p = 0.005), extension (p = 0.001), balance (p = 0.012), and FABQ subscales (physical activity: p = 0.003; work: p < 0.001) at the 3-month follow-up. Group × time interaction effects favored exergaming for ODI (p = 0.012), chair-rising (p = 0.045), stair ascent (p = 0.010), and descent (p = 0.002) times. While these changes did not meet clinical significance, exergaming was not inferior to traditional exercise in improving spinal motion, physical performance, fear-avoidance beliefs, and disability.

CONCLUSION

Exergaming appears to be a viable supplementary therapy for patients with CLBP, offering benefits across all ICF domains. Future studies with longer intervention durations are needed to assess its long-term effects.

Analysis of the Body Posture of Junior Kickboxers: An Observational Study

Background/Objectives: The purpose of this study was to assess the body posture of kickboxing players. Methods: The study group included people training as kickboxers who actively participated in the training camp of the broad national junior team in the K1 and low-kick kickboxing leagues. The control group consisted of non-training people. The age of the study group ranged from 15 to 23 years. The ages of the control group participants varied from 14 to 20 years. A body posture test was performed by using the Moiré method, in accordance with the guidelines of the manufacturer of the Moiré 4G device. Results: The body posture test performed using the Moiré method showed statistically significant differences between the kickboxing training group and the control group. The parameters that showed statistically significant differences included the size of lordosis (KLL) and the depth of lordosis (GLL) in the lumbar spine. Higher values were observed in the kickboxing training group compared to the control group. There was no statistically significant difference between the kickboxing group and the control group in other parameters. Conclusions: The asymmetrical and flexed posture required during kickboxing training did not negatively influence the competitors' spinal curvatures. Kickboxers had increased lumbar lordosis, which may be related to the specificity of the given discipline (stretching of the hamstrings and specific movements). This is a beneficial phenomenon that may reduce the risk of lower back pain. Kickboxing training did not affect the asymmetry of body posture in the sagittal plane.

Yoga, Physical Therapy and Home Exercise Effects on Chronic Low Back Pain: Pain Perception, Function, Stress, and Quality of Life in a Randomized Trial

Low back pain is a common health problem. In this study, we investigated the effects of yoga, physical therapy (PT), and home exercise (HE) on pain perception, function, stress, and quality of life in chronic low back pain (cLBP). We randomly assigned 54 participants to three distinct treatment groups: (a) a physical therapy group (PT) who received spinal stabilization exercises (SSE) combined with local heat and transcutaneous electrical stimulation; (b) a home exercise group (HE) who received SSE as part of the home program; and (c) a yoga group who received yoga exercises. The primary outcome measures were a Visual Analog Scale (VAS) for measuring pain, and the Oswestry Disability Index (ODI) to measure function. Secondary outcome measures were the Tampa Kinesiophobia Scale (TKS), Central Sensitization Inventory (CSI), pain sensitivity (L3 and deltoid R/L PPTs), Spielberger State-Trait Anxiety Inventory (STAI), plasma cortisol and DHEA-S levels, Transversus Abdominis (TrA) muscle activation, and the Nottingham Health Profile (NHP). Assessments were conducted before and after a six-week intervention period. All three groups demonstrated improvements in pain on the VAS, function on the ODI, pain sensitivity on the L3 and deltoid R/L PPTs, CSI, anxiety on the STAI, TrA muscle activation, and quality of life on the NHP (p < .05). The PT group exhibited a more pronounced improvement on the ODI score (p < .05) than the other groups. Cortisol levels only decreased in the PT group (p < .05). The exercises did not impact DHEA-S and NHP-S parameters. Thus, all interventions resulted in decreased stress, pain intensity, pain sensitivity, central sensitization, and improved function and quality of life; there was no singularly superior approach between interventions. These findings will aid in tailoring treatment programs for managing cLBP according to individual needs.

Cross-cultural adaptation and test-retest reliability assessment of a Swedish version of the exercise adherence rating scale in patients after shoulder surgery

BACKGROUND

Adherence to prescribed home exercise is an important predictor for the long-term effectiveness of exercise therapy and therefore important to evaluate. The Exercise Adherence Rating Scale (EARS) is a valid and reliable tool to assess exercise adherence behavior, but it is not translated into Swedish. This study aimed to translate EARS into Swedish and to explore the psychometric properties in terms of test-retest reliability, internal consistency as well and possible floor-/ceiling effects.

MATERIALS AND METHODS

  A translation and cultural adaptation process followed international guidelines and resulted in EARS-Sv. A total of 30 patients who had undergone shoulder surgery were included in the study and filled out EARS-Sv at two different time points. The test-retest reliability was evaluated through the weighted kappa coefficient and Intraclass Correlation Coefficient (ICC). Cronbach's alpha was used to assess internal consistency. Floor-/ceiling effects were calculated.

RESULTS

The test-retest reliability of the questionnaire was good with ICC (0.79, CI 95%) and moderate with weighted kappa-coefficient (MD= 0.58). Cronbach's alpha was considered good (0.88). A ceiling effect was registered in all 6 items of EARS-Sv.

CONCLUSION

EARS-Sv has moderate to good test-retest reliability and good internal consistency in patients who have undergone shoulder surgery.

Nonpharmacological Therapies for Musculoskeletal Injury in Military Personnel: A Systematic Review/Meta-Analysis

INTRODUCTION

Musculoskeletal (MSK) injury is an inherent risk for military personnel that can potentially impact job performance, productivity, and military readiness. Evidence is needed to show the efficacy of nonpharmacological, self-managed therapies to reduce MSK symptoms at common injury sites that are feasible for use during expeditionary operations and home stations. This systematic review and meta-analysis identified, summarized, and synthesized available evidence from randomized and non-randomized trials on the effectiveness of self-managed, home-use therapies to improve pain, muscle strength, and physical performance in military personnel with MSK injuries, when compared to controls.

METHODS

The electronic databases of MEDLINE ALL Ovid, Embase.com, Cochrane Library, Scopus, Clinicaltrial.gov, and CINAHL Complete via EBSCO were systematically searched for relevant reports published in English. Utilizing the Covidence platform and consistent with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, multiple reviewers, using pre-determined data fields, screened for eligibility, assessed risk of bias (RoB), and performed data extraction. Evaluation of treatment effectiveness was determined using multilevel mixed-effects meta-analysis.

RESULTS

The database and register search yielded 1,643 reports that were screened for eligibility. After screening of titles/abstracts and full texts, 21 reports were identified for evidence synthesis. Of these, two reports were excluded and two described the same study, resulting in a final list of 18 studies (19 reports). For quality assessment, the overall RoB for the 18 studies was categorized as 33.3% low risk, 55.6% with some concerns, and 11.1% high risk. Across the five domains of bias, 70% of the reports were classified as low risk. This systematic review found that the differences in interventions, outcome measures, and design between the studies were associated with a substantial degree of heterogeneity (I2 = 60.74%), with a small overall improvement in outcomes of the interventions relative to their specific control (standard mean difference 0.28; 95% CI, 0.12 to 0.45). There were varying degrees of heterogeneity for individual body regions. This was due, in part, to a small number of studies per bodily location and differences in the study designs. For the neck/shoulder, heterogeneity was moderate, with the clearest positive effect being for physical performance outcomes via other medical devices. For the back, there was substantial heterogeneity between studies, with modest evidence that pain was favorably improved by other medical devices and exercise interventions. For the leg, one study showed a clear large effect for other medical devices (shockwave treatment) on pain with substantial heterogeneity. The best evidence for positive effects was for the knee, with mainly negligible heterogeneity and some benefits from bracing, electrotherapy, and exercise.

CONCLUSION

Evidence showed small beneficial effects in pain, strength, and physical performance by individual body regions for some interventions, compared to controls. The best evidence for a positive effect was for the knee. The findings suggest that some benefit may be obtained by including several treatments during deployment in austere environments and prolonged casualty care scenarios of military personnel with MSK injuries. Further research is warranted to better assess the potential benefits of using these treatments during deployments in austere environments as part of an individualized, multimodal approach for MSK injuries.

A Randomized Controlled Trial of Active Stretching of the Hamstrings and Core Control for Low Back Pain and Musculoskeletal Discomfort during Prolonged Sitting among Young People

Introduction: Stretching exercises are important in both the prevention and treatment of nonspecific low back pain (NLBP). The aim of this trial was to determine whether an 8-week active hamstring stretching protocol combined with core stabilization and education regarding the maintenance of a neutral lumbar spine during activities could reduce NLBP and low back discomfort during prolonged sitting among young people. Methods: Participants (52 students aged 18-25) were randomly assigned to one of two groups: the Experimental group (the hamstring stretching group) and the Control group (only education). The intervention was conducted for 8 weeks. The primary outcome measures were pain intensity (VAS), low back discomfort (LBD), and functional disability (ODI). The secondary outcome measures were satisfaction with the intervention (GPE) and flexibility of the hamstring (SLR). Results: After the 8-week intervention in the E-group, results of VAS, ODI, and LBD were significantly lower comparing to baseline. In the C-group, no significant differences were observed. After the exercises program, there were differences between the E-group and C-group in VAS, LBD, GPE, and SLR tests (p < 0.05, p < 0.05, p < 0.05, and p < 0.0001, respectively). Conclusions: In conclusion, our study provides compelling evidence that an eight-week program of active hamstring stretching and core stabilization exercises can significantly reduce NLBP and musculoskeletal discomfort during prolonged sitting in young adults. These findings highlight the importance of targeted exercise interventions in managing and preventing NLBP, particularly among sedentary populations. Further research is warranted to confirm these findings and explore their applicability to broader populations and over extended periods.

Exploring the association between adherence to home-based exercise recommendations and recovery of nonspecific low back pain: a prospective cohort study

BACKGROUND

Adherence to home-based exercise (HBE) recommendations is critical in physiotherapy for patients with low back pain (LBP). However, limited research has explored its connection with clinical outcomes. This study examined how adherence to HBE relates to changes in physical function, pain intensity, and recovery from LBP in patients undergoing physiotherapy treatment.

METHODS

Data from a multicenter cluster randomized controlled trial in the Netherlands involving patients with LBP from 58 primary care physiotherapy practices were used. Adherence to HBE was assessed with the Exercise Adherence Scale (EXAS) at each treatment session. Previously identified adherence trajectories served as a longitudinal measure of adherence and included the classes "declining adherence" (12% of participants), "stable adherence" (45%), and "increasing adherence" (43%). The main outcomes included disability (Oswestry Disability Index), pain (Numeric Pain Rating Scale), and recovery (pain-free for > 4 weeks), which were measured at baseline and after three months. Linear and binomial logistic regression analyses adjusted for confounders were used to examine adherence-outcome relationships.

RESULTS

In the parent trial, 208 participants were included. EXAS scores were available for 173 participants, collected over a median of 4.0 treatment sessions (IQR 3.0 to 6.0). Forty-five (28.5%) patients considered themselves to have recovered after three months. The median changes in the Oswestry Disability Index and Numeric Pain Rating Scale were - 8 (IQR - 1 to -20) and - 2 (IQR - 0.5 to -4), respectively. The mean EXAS scores varied among patient classes: "declining adherence" (46.0, SD 19.4), "stable adherence" (81.0, SD 12.4), and "increasing adherence" (39.9, SD 25.3), with an overall mean of 59.2 (SD 25.3). No associations between adherence and changes in physical functioning or pain were found in the regression analyses.

CONCLUSIONS

No association between adherence to HBE recommendations and changes in clinical outcomes in patients with LBP was found. These findings suggest that the relationship between adherence to HBE recommendations and treatment outcomes may be more complex than initially assumed. Further research using detailed longitudinal data combined with qualitative methods to investigate patient motivation and beliefs may lead to a deeper understanding of the relationship between adherence and clinical outcomes in patients with LBP.

Barriers and Facilitators of Vestibular Rehabilitation: Patients and Physiotherapists' Perspectives

BACKGROUND AND PURPOSE

Poor adherence to vestibular rehabilitation protocols is a known barrier to optimal care. Vestibular clinicians' comprehensive understanding of the barriers and facilitators to vestibular home exercise programs (VHEP) is a key element to achieving optimal care in the context of vestibular rehabilitation. The aims of this study are as follows: (1) to identify primary barriers and facilitators to VHEP from the perspective of patients with vestibular dysfunction and vestibular physical therapists (PTs); and (2) to provide strategies for clinicians to improve adherence and outcomes of VHEP.

METHODS

A qualitative research with single-session focus groups conducted separately for: (1) patients with vestibular disorders and (2) vestibular PTs. Six focus groups were conducted, 3 for each population, with a total of 39 participants. An online survey was conducted to evaluate the estimates of adherence rates, followed by a structured discussion over barriers and facilitators to VHEP as perceived by patients and PTs. Thematic data analyses were performed using a mixed deductive-inductive approach.

RESULTS

Eighteen patients with vestibular disorders and 21 experienced vestibular PTs participated in this study. Six barrier categories and 5 facilitator categories were identified. Barriers included motivation aspects, provocation of symptoms, time management, associated impairments, missing guidance and feedback, and psychosocial factors. Facilitators included motivation aspects, time management, patient education and exercise instructions, exercise setting, and associated symptom management.

DISCUSSION AND CONCLUSIONS

Clinicians who prescribe home exercise to patients with vestibular disorders can use this information about common barriers and facilitators for patient education and to provide optimal care and improve rehabilitation outcomes.

Effects of Remote Versus In-Person Training on Metabolic Profiles and Body Composition of Physically Inactive Adults: Randomized Clinical Trial

The COVID-19 pandemic has pushed the population to adopt increasingly sedentary lifestyles. Faced with this problem, remote training appears as a practical and inexpensive strategy to promote physically active lifestyles. The aim of this research was to compare the effects of remote versus in-person training on metabolic profiles and body composition of physically inactive adults. This research was conducted through a randomized, single-blind clinical trial with balanced block randomization. The sample consisted of 30 physically inactive subjects of both sexes between 18 and 30 years of age. The sample was selected using a voluntary public call. The 30 subjects were randomized into three groups of 10 people each. One group trained for 36 sessions remotely, and the other did so in person. The control group did not have a training plan. The variables evaluated pre- and post-intervention were body composition by bioimpedance, grip strength through dynamometry, primary outcome, and metabolic profile assessed from a capillary sample using the CARDIOCHEK equipment. In the remote training group, significant gains were evident in the variables of weight (p = 0.042, d = 1.119), muscle percentage (p = 0.032, d = 0.499), and fat percentage (p = 0.001, d = 1.132), visceral fat (p = 0.032, d = 0.424), total cholesterol (p = 0.001, d = 1.213), HDL (p = 0.001, d = 0.534), LDL (p = 0.001, d = 0.973), triglycerides (p = 0.001, d = 0.583), and grip strength (p = 0.001, d = 1.201). When comparing the effects between the remote and in-person training groups, it is evident that the improvements were similar in all variables, except for glucose, in which the in-person group had a greater value reduction.

Exploring the immediate and short-term effect of lumbar spinal manipulation on pressure pain threshold: a randomized controlled trial of healthy participants

BACKGROUND

Lumbar spinal manipulative therapy (SMT) is a common intervention used to treat low back pain (LBP); however, the exact neurophysiological mechanisms of SMT reducing pain measured through pain pressure threshold (PPT) have not been fully explored beyond an immediate timeframe (e.g., immediately or five-minutes following) referencing a control group. Therefore, the purpose of this study was to investigate the neurophysiological effects of lumbar SMT compared to deactivated ultrasound using PPT immediately following and 30-minutes following SMT.

METHODS

A longitudinal, randomized controlled trial design was conducted between September to October 2023. Fifty-five participants were randomized into a control group of deactivated ultrasound (n = 29) or treatment group of right sidelying lumbar SMT (n = 26). PPT, recorded at the right posterior superior iliac spine (PSIS), was documented for each participant in each group prior to intervention, immediately, and 30-minutes after. A repeated measures ANOVA, with a post-hoc Bonferroni adjustment, was used to assess within-group and between-group differences in PPT. The significance level was set at a < 0.05 a priori.

RESULTS

Statistically significant differences were found between the deactivated ultrasound and lumbar SMT groups immediately (p = .05) and 30-minutes (p = .02) following intervention. A significant difference in the lumbar SMT group was identified from baseline to immediately following (p < .001) and 30-minutes following (p < .001), but no differences between immediately following and 30-minutes following intervention (p = .10). The deactivated ultrasound group demonstrated a difference between baseline and immediately after intervention with a reduced PPT (p = .003), but no significant difference was found from baseline to 30-minutes (p = .11) or immediately after intervention to 30-minutes (p = 1.0).

CONCLUSION

A right sidelying lumbar manipulation increased PPT at the right PSIS immediately after that lasted to 30-minutes when compared to a deactivated ultrasound control group. Future studies should further explore beyond the immediate and short-term neurophysiological effects of lumbar SMT to validate these findings.

TRIAL REGISTRATION

This study was retrospectively registered on 4 December 2023 in ClinicalTrials (database registration number NCT06156605).

On-Site Physiotherapy in Emergency Department Patients Presenting with Nonspecific Low Back Pain: A Randomized Controlled Trial

Background: There is a high incidence of nonspecific Low Back Pain (LBP) in patients visiting Emergency Departments (EDs), but there is a lack of knowledge regarding emergency physiotherapy for LBP. The effect of on-site physiotherapy in these patients was therefore never demonstrated. We assessed short-term outcomes, feasibility and patient satisfaction with physiotherapy in ED patients presenting with nonspecific LBP. Methods: A block-randomized, controlled, open-label trial with a follow-up of 42 days. Patients aged 18 years or older presenting to an ED with nonspecific LBP were prospectively enrolled. Both groups received the same booklet with written information on LBP management and exercises. Patients in the intervention group were given additional instructions by a certified physiotherapist. Results: We included 86 patients in the primary analysis. The median age was 40, and 40.7% were female. At day 7, the median Oswestry Disability Index (ODI) was 2 points lower in the intervention group compared to the control group, which was not statistically significant. There was no between-group difference in pain at day 7. Patients who received physiotherapy felt significantly more confident with the exercises they were taught (p = 0.004, effect size = 0.3 [95% CI 0.1 to 0.5]). Conclusions: On-site physiotherapy in ED patients presenting with nonspecific low back pain is associated with higher patient satisfaction, compared to standard of care. The effect of physiotherapy was small, with only minimal improvement in disability, but without a reduction in pain. Despite the very small effect size, physiotherapeutic interventions should be investigated in larger cohorts with an extended intervention including patient education, exercises, and other physiotherapeutic modalities.

The Effectiveness of Acupuncture for Low Back Pain: An Umbrella Review and Meta-Analysis

Recommendations on the use of acupuncture in managing low back pain (LBP) vary across different guidelines. The methodological quality of existing systematic reviews and meta-analyses on this topic also demonstrates considerable diversity, potentially leading to biased conclusions. Therefore, we comprehensively searched PubMed, EMBASE, Web of Science, Cochrane Database of Systematic Reviews, and Chinese National Knowledge Infrastructure (CNKI) databases and conducted an umbrella review. Scrutiny was performed to ascertain whether primary studies within the systematic reviews and meta-analyses adhered to our inclusion criteria, followed by a meticulous reanalysis of pertinent data. Participant numbers, heterogeneity, publication bias, and excessive significance were taken into account when assessing the credibility of the evidence. For robustness, sensitivity analysis was performed using the leave-one-out method. The results of the umbrella review yielded highly suggestive evidence in favor of the immediate and short-term analgesic effects of acupuncture, with suggestive evidence supporting intermediate-term analgesic effects. However, the effectiveness of acupuncture on disability improvement has demonstrated weak to suggestive evidence. Evidence supporting the enhancement of quality of life by acupuncture is limited. The leave-one-out analysis corroborated the robustness of the meta-analysis, further confirming the credibility of the findings. This umbrella review indicated that the most significant advantage of acupuncture for LBP is its capacity to reduce pain.

Quality of Life in Patients with Chronic Low Back Pain and Differences by Sex: A Longitudinal Study

BACKGROUND

The experience of chronic low back pain has a significant impact on the quality of life of affected people, resulting in difficulties in performing basic activities of daily living.

AIM

To study the perceived quality of life of people affected by chronic low back pain and the associated factors by sex.

METHODS

A prospective, longitudinal and observational design was used.

RESULTS

A total of 129 people (58.1% women) with chronic low back pain were studied. The mean pain intensity scores were of moderate severity (6.42 points), with a modest improvement at follow-up (6.17 points). Epidural nerve blocks were the most effective therapeutic intervention in reducing the intensity of pain. Participants described a negative perception of their health with regard to quality of life, with low scores for the two constructs both at baseline (health index, 0.444; perception of health, 38.76 points) and at follow-up (health index, 0.447; perception of health, 40.43 points). Participants had severe functional limitation scores (50.79 points). The results were significantly better among men. There was an inverse relationship between the average pain intensity (β = -0.304; p < 0.001), functional limitation (β = -0.466; p < 0.001) and mental health (β = -0.565; p < 0.001) and quality of life.

CONCLUSIONS

The chronification of low back pain complicates people's biopsychosocial adaptation to life. There is a longitudinal inverse association between pain and functional limitation and health-related quality of life.

Software-based interventions for low back pain management: A systematic review and meta-analysis

INTRODUCTION

Using software for self-management interventions can improve health outcomes for individuals with low back pain, but there is a dearth of research to confirm its effectiveness. Additionally, no known research has evaluated the effective elements of software-based interventions for low back pain self-management components. This study aimed to synthesize the effectiveness of software-based interventions to promote self-management health outcomes among individuals with low back pain.

DESIGN

A systematic review and meta-analysis was conducted.

METHODS

Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement, relevant studies up to July 2022 were searched via four electronic databases: PubMed, Embase, Cumulative Index to Nursing and Allied Health Literature, and Web of Science.

RESULTS

4908 adults with low back pain who participated in 23 studies were included. Software-based interventions were effective in reducing fear avoidance (mean difference [MD] = -0.95, 95% CI: -1.45 to -0.44), pain catastrophizing (MD = -1.31, 95% CI: -1.84 to -0.78), disability (MD = -8.21, 95% CI: -13.02 to -3.39), and pain intensity (MD = -0.86, 95% CI: -1.17 to -0.55). Specifically, interventions that included an exercise component were more effective in reducing pain and disability. Additionally, cognitive behavioral therapy (CBT) intervention significantly reduced fear avoidance and pain catastrophizing but had no noticeable impact on disability and pain compared to standard treatment. The certainty of the evidence in this review varied from very low to high across outcomes. The heterogeneity of the study results was significant, suggesting that future studies in this area could optimize the design, time points, measures, and outcomes to strengthen the evidence.

CONCLUSIONS

Low back pain self-management interventions delivered through software-based programs effectively reduce pain intensity, disability, fear avoidance, and pain catastrophizing.

CLINICAL RELEVANCE

Low back pain is among the most common reasons for seeking healthcare visits. Combining exercise and counseling through soft-based programs may effectively address this issue and its associated suffering and disability.

The Impact of Exercise Prescription Variables on Intervention Outcomes in Musculoskeletal Pain: An Umbrella Review of Systematic Reviews

BACKGROUND

Musculoskeletal pain conditions are the largest contributors to disability and healthcare burden globally. Exercise interventions improve physical function and quality of life in individuals with musculoskeletal pain, yet optimal exercise prescription variables (e.g. duration, frequency, intensity) are unclear.

OBJECTIVE

We aimed to examine evidence gaps, methodological quality and exercise prescription recommendations in systematic reviews of exercise for musculoskeletal pain.

METHODS

In our prospectively registered umbrella review, PubMed, SPORTDiscus, Cochrane Database of Systematic Reviews, EMBASE, and CINAHL were searched from inception to 14 February 2023. Backward citation tracking was performed. We included peer-reviewed, English language, systematic reviews and meta-analyses of randomized controlled trials (RCTs) and controlled clinical trials (CCTs) that compared exercise with conservative treatment, placebo or other exercise interventions in adults with musculoskeletal pain. Data were extracted from the following groups of reviews based on their reporting of exercise prescription data and analysis of the relationship between prescription variables and outcomes: (1) those that did not report any exercise prescription data, (2) those that reported exercise prescription data but did not perform a quantitative analysis and (3) those that performed a quantitative analysis of the relationship between exercise prescription variables and outcomes. Outcome measures were physical function, pain, mental health, adverse effects and adherence to treatment. AMSTAR-2 (A MeaSurement Tool to Assess systematic Reviews) was used to assess methodological quality.

RESULTS

From 6757 records, 274 systematic reviews were included. 6.6% of reviews did not report any exercise prescription data, and only 10.9% quantitatively analyzed the relationship between prescription variables and the outcome(s). The overall methodological quality was critically low in 85% of reviews.

CONCLUSION

High methodological quality evidence is lacking for optimal exercise training prescription variables in individuals with musculoskeletal pain. To better inform practice and evidence gaps, future systematic reviews should (1) identify optimum exercise prescription variables, for example, via dose-response (network) meta-analysis, (2) perform high-quality reviews per AMSTAR-2 criteria and (3) include outcomes of mental health, adverse events and exercise adherence.

Electrical dry needling versus a non-invasive multicomponent intervention in the treatment of myofascial trigger points in patients with chronic low back pain: A randomised clinical trial

OBJECTIVE

To compare the effects of electrical dry needling with a non-invasive multi-component intervention in patients with chronic low back pain.

DESIGN

A randomised single-blind clinical trial.

SETTING

Outpatient Physiotherapy Clinic; home.

PARTICIPANTS

Sixty-four patients with chronic low back pain aged 30-65 years.

INTERVENTIONS

Six-week electrical dry needling on myofascial trigger points, and a non-invasive multicomponent intervention (home exercise programme, stretching and ischemic compression).

MAIN MEASURES

Pain (Visual Analogue Scale), disability (Roland-Morris Disability Questionnaire and Oswestry Disability Index), kinesiophobia (Tampa Scale of Kinesiophobia), quality of life and sleep (Short Form 36-item Health Survey and Pittsburgh Sleep Quality Index), isometric endurance of trunk flexor muscles (McQuade test), lumbar mobility in flexion (finger-to-floor distance), and pressure pain threshold (algometer) were assessed at baseline, after 6 weeks, and after 2 months.

RESULTS

ANOVA showed statistically significant differences in group-by-time interaction for most pain pressure thresholds of myofascial trigger points (P < 0.05), for disability (Roland-Morris Disability Questionnaire: F = 6.14, P = 0.016; and Oswestry Disability Index: F = 7.36, P = 0.009), for trunk anteflexion (F = 10.03, P = 0.002) and for habitual sleep efficacy (F = 6.65, P = 0.012), use of hypnotics (F = 4.77, P = 0.033) and total score of quality of sleep (F = 8.23, P = 0.006).

CONCLUSIONS

In comparison to a non-invasive multicomponent intervention, electrical dry needling has more positive effects on disability, pain intensity, kinesiophobia, and reducing patients' sensitivity to myofascial trigger points pressure, at post-treatment and at 2 months.

Trajectories of Adherence to Home-Based Exercise Recommendations Among People With Low Back Pain: A Longitudinal Analysis

OBJECTIVE

This study aimed to examine the presence of distinct trajectories of adherence to home-based exercise recommendations among people with low back pain (LBP). This study also aimed to identify differences in baseline characteristics among groups.

METHODS

This study was a secondary analysis of a prospective, multicenter cluster randomized controlled trial investigating the cost-effectiveness of a stratified blended physical therapist intervention compared to usual care physical therapy in patients with LBP. The intervention group received usual care with integrated support via a smartphone app. A total of 208 patients were recruited from 58 primary care physical therapist practices. Baseline data included patient characteristics, physical functioning, pain intensity, physical activity, fear avoidance, pain catastrophizing, self-efficacy, self-management ability, and health-related quality of life. The Exercise Adherence Scale (score range = 0-100) was used to measure adherence during each treatment session. Latent class growth analysis was used to estimate trajectories of adherence.

RESULTS

Adherence data were available from 173 out of 208 patients (83%). Data were collected during an average of 5.1 (standard deviation [SD] = 2.5) treatment sessions, with total treatment duration of 51 (SD = 41.7) days. Three trajectory classes were identified: "declining adherence" (12%), "stable adherence" (45%), and "increasing adherence" (43%). No differences in baseline characteristic were found between groups.

CONCLUSION

Three adherence trajectories to exercise recommendations were identified in patients with LBP. However, baseline characteristics cannot identify a patient's trajectory group.

IMPACT

Despite the presence of distinct trajectories of adherence in patients with LBP, physical therapists should not attempt to place a patient in a trajectory group at the start of treatment. Instead, adherence should be closely monitored as treatment progresses and supported when required as part of an ongoing process.

Therapeutic Exercise Parameters, Considerations and Recommendations for the Treatment of Non-Specific Low Back Pain: International DELPHI Study

BACKGROUND

Therapeutic exercise (TE) recommendations for non-specific low back pain (LBP) are meant to support therapy choices for people who suffer from this condition. The aim of this study was to reach an agreement on the definition and use of TE in the care of people with LBP.

METHODS

A Delphi study was carried out with a formal consensus procedure and sufficient scientific evidence, using an established methodology. Four rounds of anonymous questionnaires were administered to create useful suggestions and instructions in terms of the therapeutic activity for patients with LBP, and a group consensus conference.

RESULTS

A consensus was reached on most of the questions after 35 physiotherapists completed the questionnaires. Participants agreed that proper TE requires correct posture, body awareness, breathing, movement control, and instruction. Patients with LBP were advised to participate in supervised sessions twice a week for 30 to 60 min for a period of 3 to 6 months. Participants added that tailored evaluation and exercise prescription, monitoring, and functional integration of exercise, as well as using specific equipment, would benefit patients with LBP.

CONCLUSIONS

TE recommendations for patients with LBP should be dosed and customized based on their personal psychological needs, level of fitness, and kinesiophobia.

Acute Effects of Whole-Body Electrostimulation Combined with Stretching on Lower Back Pain

Data from recent studies suggest that whole-body electromyostimulation (WB-EMS) is a time-effective and tailored intervention for chronic lower back pain (CLBP). The aim of this non-randomized controlled study was to compare the efficacy of a WB-EMS training and the association between WB-EMS specific training with passive stretching (Well Back System, [WBS]) on CLBP. Forty patients with CLBP, 43-81 years old, were assigned to one of the two groups: WB-EMS (n=20) and WB-EMS+WBS (n=20). Both groups completed 12 sessions (8 weeks) of the WB-EMS protocol (2×20 minutes/week). The second group performed core-specific exercises with WB-EMS plus 6 extra stretching sessions (30 minutes each). Primary study endpoints were based on changes on the visual analogue scale (VAS) and changes on the Oswestry Low Back Disability Questionnaire (ODI). Secondary study endpoints were percentage changes of maximum trunk flexion (Sit & Reach, [SR]) and changes in consumption of painkillers. Both interventions significantly improved VAS, ODI, and SR values (p range: 0.04;<0.001). However, the change of VAS (-46% vs. -17%, p<0.001), ODI (-53% vs. -17%, p<0.001), and SR (+ 7 vs.+3 cm, p=0.001) were significantly higher in the WB-EMS+WBS group compared to the WB-EMS group. The working method with WB-EMS+WBS can be a joint-friendly, individualized form to decrease CLBP.

Effects of usual yoga practice on the diaphragmatic contractility: A cross-sectional controlled study

Objectives

The aim of this study is to observe and compare the effects of regular yoga practice on the main inspiratory muscle, the diaphragm, by analyzing its thickness, excursion, velocity and contraction time, using ultrasound.

Design

A Cross-Sectional Controlled Study.

Participants

80 healthy subjects (40 habitual yoga practitioners and 40 non-practitioners), without previous respiratory pathology participated in this study. During maximum diaphragmatic breathing, the diaphragmatic thickness (at rest and after maximum inspiration), excursion, velocity and contraction time were measured by ultrasound.

Results

in the experimental group, practicing yoga, statistically significant differences (p < 0.001) were observed compared to the control group, not practicing, in the thickness of the diaphragm at rest (0.26 ± 0.02 vs 0.22 ± 0.01 cm); the diaphragmatic thickness in maximum inspiration (0.34 ± 0.03 vs 0.28 ± 0.03 cm); contraction velocity (1.54 ± 0.54 vs 2.23 ± 0.86 cm/s), contraction time (3.28 ± 0.45 vs 2.58 ± 0.49 s) and Borg scale of perceived exertion (1.05 ± 1.6 vs 1.70 ± 1.34), p = 0.05. However, the diaphragmatic excursion was greater in the control group (5.45 ± 1.42 vs 4.87 ± 1.33 cm) with no statistically significant differences (p = 0.06).

Conclusions

the regular practice of yoga improves the parameters of diaphragm thickness, speed and contraction time measured in ultrasound and the sensation of perceived exertion during a maximum inspiration. So it can be considered as another method for training the inspiratory muscles in clinical practice.

The effectiveness of clinic versus home-based, artificial intelligence-guided therapy in patients with low back pain: Non-randomized clinical trial

BACKGROUND

Low back pain is a common cause of disability in the US with increasing financial burden on healthcare. A variety of treatment options exist to combat LBP. Home-based therapy is a low-cost option, but there is a lack of data on how it compares to therapy in clinical settings. It was hypothesized that when using artificial intelligence-guided therapy, supervised in-clinic interventions would have a greater influence on patient-reported outcomes and strength than unsupervised, home interventions.

METHODS

This is a non-randomized controlled trial of 51 patients (28 female, 23 male). The investigation compared an 8-week, core-focused exercise intervention in a Clinic (supervised) versus Home (unsupervised) setting. Outcome variables included measures of strength, performance, and patient-reported outcomes related to function. Generalized linear regression (p < 0.05) was used to evaluate outcomes were evaluated with respect to sex, intervention setting, and time.

FINDINGS

Male subjects exhibited greater strength (p ≤ 0.02) but not greater patient-reported outcomes (p ≥ 0.30) than females. The Clinic group exhibited slightly greater lateral pull-down strength (p = 0.002), greater eccentric phase range of motion during overhead press (p < 0.01), and shorter concentric phase duration during bench press (p < 0.01) than the Home group. Significance between groups was not observed in any other strength, performance, or patient-reported outcome (p ≥ 0.11).

INTERPRETATION

A lack of consistent significance indicated that the hypothesis was not supported. AI-guided, telehealth exercise produced comparable outcomes in both home and clinical settings. Telehealth options may offer a lower-cost alternative to clinic-based exercise therapy for patients with nonspecific lower back pain.

Availability, Quality, and Evidence-Based Content of mHealth Apps for the Treatment of Nonspecific Low Back Pain in the German Language: Systematic Assessment

BACKGROUND

Nonspecific low back pain (NSLBP) carries significant socioeconomic relevance and leads to substantial difficulties for those who are affected by it. The effectiveness of app-based treatments has been confirmed, and clinicians are recommended to use such interventions. As 88.8% of the German population uses smartphones, apps could support therapy. The available apps in mobile app stores are poorly regulated, and their quality can vary. Overviews of the availability and quality of mobile apps for Australia, Great Britain, and Spain have been compiled, but this has not yet been done for Germany.

OBJECTIVE

We aimed to provide an overview of the availability and content-related quality of apps for the treatment of NSLBP in the German language.

METHODS

A systematic search for apps on iOS and Android was conducted on July 6, 2022, in the Apple App Store and Google Play Store. The inclusion and exclusion criteria were defined before the search. Apps in the German language that were available in both stores were eligible. To check for evidence, the apps found were assessed using checklists based on the German national guideline for NSLBP and the British equivalent of the National Institute for Health and Care Excellence. The quality of the apps was measured using the Mobile Application Rating Scale. To control potential inaccuracies, a second reviewer resurveyed the outcomes for 30% (3/8) of the apps and checked the inclusion and exclusion criteria for these apps. The outcomes, measured using the assessment tools, are presented in tables with descriptive statistics. Furthermore, the characteristics of the included apps were summarized.

RESULTS

In total, 8 apps were included for assessment. Features provided with different frequencies were exercise tracking of prefabricated or adaptable workout programs, educational aspects, artificial intelligence-based therapy or workout programs, and motion detection. All apps met some recommendations by the German national guideline and used forms of exercises as recommended by the National Institute for Health and Care Excellence guideline. The mean value of items rated as "Yes" was 5.75 (SD 2.71) out of 16. The best-rated app received an answer of "Yes" for 11 items. The mean Mobile Application Rating Scale quality score was 3.61 (SD 0.55). The highest mean score was obtained in "Section B-Functionality" (mean 3.81, SD 0.54).

CONCLUSIONS

Available apps in the German language meet guideline recommendations and are mostly of acceptable or good quality. Their use as a therapy supplement could help promote the implementation of home-based exercise protocols. A new assessment tool to obtain ratings on apps for the treatment of NSLBP, combining aspects of quality and evidence-based best practices, could be useful.

Clinical efficacy of breathing training combined with core stability training in chronic nonspecific low back pain

Objective

The study aimed to assess the clinical efficacy of breathing training combined with core stability training in chronic nonspecific low back pain (CNLBP).

Methods

This was a retrospective study. Of 60 included patients with CNLBP admitted by the Sichuan Province Orthopedic Hospital between December 2020 and February 2022. Random number table method was used to divide thirty patients to a control group, and the rest 30 to an observation group. The control group received core stability training, while the observation group underwent breathing training in addition to the exact treatment provided for the control group. To assess the utility of breathing and core stability training for CNLBP treatment, intergroup comparisons were made for clinical outcomes, the VAS, SF- 36, and SCODI scores before treatment and at three and seven weeks post-treatment, and static and dynamic low-back muscular endurance before and after treatment.

Results

The observation group had an overall response rate (ORR) of 96.67%, significantly higher than that (73.33%) of the control group (p< 0.05). Following the intervention, the VAS and SCODI scores declined in both groups; The SF-36 score was elevated in both groups, and likewise. At the end of treatment, both groups exhibited improved static and dynamic muscular endurance of the low back, and the improvement was significantly more distinct in the observation group (p< 0.05).

Conclusion

Compared with core stability training as a sole treatment, breathing training combined with core stability training can yield better outcomes, ameliorate lumbar spine function, relieve pain and enhance low-back muscular endurance in patients with CNLBP.

[Complementary and alternative medicine-An option for chronic pain patients?]

The interest of patients with chronic pain in complementary and alternative medicine (CAM) is high. The aim of an accompanying complementary therapy is to strengthen the patient's self-efficacy, the ability to make decisions and the autonomy. The best evidence exists for physical activity and a balanced diet. Exercise combinations of strength and endurance as well as targeted strengthening of the muscles in the area of the pain are particularly suitable. When choosing the form of exercise, low-threshold training options are recommended. There is no reliable evidence for kinesio taping, homeopathy, neural therapy and draining procedures. The extensive data on acupuncture must be interpreted taking methodological limitations into account. Heat applications can support multimodal pain therapy. In the case of anti-inflammatory phytotherapeutic agents, there are good rationales from basic research and reliable empirical knowledge regarding the dosage. The evidence on cannabis is low.

In non-specific low back pain, is an exercise program carried out through telerehabilitation as effective as one carried out in a physiotherapy center? A controlled randomized trial

BACKGROUND

s:The effectiveness of telerehabilitation (TLRH) in patients with non-specific low back pain (NLBP) remains unknown. No study till date has investigated the efficacy of a mobile-based TLRH in patients with NLBP.

OBJECTIVES

To investigate if a TLRH program is as effective as a clinical exercise programme in improving disability, pain intensity, pain catastrophizing, and hip pain and strength in patients with NLBP.

DESIGN

Single-blind, two-armed, randomized controlled study.

METHOD

A total of 71 individuals with NLBP were randomly allocated to either the TLRH home group (TLRH) or clinic group (CG). The TLRH followed exercise videos and read information on pain neurophysiology. The CG performed the same exercises and received on-site pain education. Both groups performed the exercises twice weekly for 8 weeks. Disability, pain intensity, pain catastrophizing, and hip pain and strength were assessed at baseline, at post-treatment, and at three months.

RESULTS

Statistically significant differences for time-by-group interaction were detected in the strength of left hip flexors (supine [F = 8.356; p = .005]; sitting [F = 9.828; p = .003]), right hip extensors with extended knee [F = 7.461; p = .008], left hip extensors (extended knee [F = 13.175; p = .001]; flexed knee [F = 13.505; p < .001]), pain during flexion of the right [F = 5.133; p = .027] and left [F = 4.731; p = .033] hips in the supine position, disability [F = 4.557; p = .014], and pain catastrophizing [F = 14.132; p < .001].

CONCLUSION

A TLRH mobile-based is as effective as clinical treatment in improving disability, pain catastrophizing, and pain and strength of the hip structures in patients with NLBP.

Effects of Exergaming on Musculoskeletal Pain in Older Adults: Systematic Review and Meta-analysis

BACKGROUND

Exercise is effective for musculoskeletal pain. However, physical, social, and environmental factors make it difficult for older adults to persist in exercising. Exergaming is a new pathway that combines exercise with gameplay and may be helpful for older adults to overcome these difficulties and engage in regular exercise.

OBJECTIVE

This systematic review aimed to determine the efficacy of exergaming to improve musculoskeletal pain in older adults.

METHODS

The search was performed in 5 databases (PubMed, Embase, CINAHL, Web of Science, and Cochrane Library). The risk of bias for randomized controlled studies was assessed using the revised Cochrane Risk of Bias tool in randomized trials (RoB 2), and the methodological quality was assessed using the Physiotherapy Evidence-Based Database scale. Standardized mean difference and 95% CI were calculated using fixed-effects model meta-analyses in the Review Manager version 5.3 (RevMan 5.3).

RESULTS

Seven randomized controlled studies were included, which contained 264 older adults. Three of the 7 studies reported significant improvements in pain after the exergaming intervention, but only 1 reported a significant difference between groups after adjustment for baseline (P<.05), and another reported a significant improvement in thermal pain between the 2 groups (P<.001). The results of the meta-analysis of the 7 studies showed no statistically significant improvement in pain compared to the control group (standardized mean difference -0.22; 95% CI -0.47 to 0.02; P=.07).

CONCLUSIONS

Although the effects of exergames on musculoskeletal pain in older adults are unknown, exergame training is generally safe, fun, and appealing to older adults. Unsupervised exercise at home is feasible and cost-effective. However, most of the current studies have used commercial exergames, and it is recommended that there should be more cooperation between industries in the future to develop professional rehabilitation exergames that are more suitable for older adults. The sample sizes of the studies included are small, the risk of bias is high, and the results should be interpreted with caution. Further randomized controlled studies with large sample sizes, high quality, and rigor are needed in the future.

Decreased Interoceptive Awareness as a Risk Factor for Moderate to Severe Pain in Japanese Full-Time Workers: A Longitudinal Cohort Study

Interoceptive awareness, the conscious perception of internal bodily states, is a key construct of mind-body interaction. Decreases in interoceptive awareness, as measured by the Multidimensional Assessment of Interoceptive Awareness (MAIA), are found in chronic pain patients. In this study, we explored whether a specific aspect of interoceptive awareness is a risk for the onset and chronicity of pain. A longitudinal cohort study was conducted in 2018 and 2020 among a sample of full-time workers in an industrial manufacturing company in Japan. Participants completed a questionnaire on pain intensity, MAIA, exercise habits, kinesiophobia, psychological distress and work stress. Principal component analyses using the MAIA identified two principal components: self-control and emotional stability. Low emotional stability was associated with the prevalence of moderate to severe pain in 2020 among people with mild or no pain in 2018 (p < 0.01). Lack of exercise habits were associated with the prevalence of moderate to severe pain in 2020 among people with pain in 2018 (p < 0.01). Furthermore, exercise habits were associated with reduction in kinesiophobia among people with moderate to severe pain in 2018 (p = 0.047). Overall, these findings indicate that low emotional stability may be a risk for the onset of moderate to severe pain; lack of exercise habits may sustain kinesiophobia and be a risk for the chronicity of pain.

Exercise Therapy in Nonspecific Low Back Pain among Individuals with Lower-Limb Amputation: A Systematic Review

Low back pain is very common condition that often becomes a long-lasting problem in prostheses users after lower limb amputation. The presented study aims to decide the potential benefits of exercise therapy on low back pain among lower limb amputees by using a systematic review. The PICO technique was used to answer the primary issue of this review: Does exercise treatment lessen the prevalence of low back pain in the population of lower limb amputees? Systematic review was conducted in the following databases: Medline-PubMed, EMBASE, Scopus, and Web of Science. Studies up to September 2010 published in English are included. Aim, target population, development and execution strategies, and treatment suggestions were among the data gathered. The primary outcomes of interest were exercise interventions as a therapy for low back pain but only two articles met including criteria. The search was broadened and 21 studies describing biomechanical changes in gait and pelvic-spine posture were analysed. This review indicates that movement therapy is a potential treatment strategy in low back pain among amputees. The major limitation of the study is the very heterogenous group of subjects in terms of amputation level, baseline activity level and comorbidities. We used a procedure that was registered in PROSPERO (CRD42022345556) to perform this systematic review of systematic reviews. There is a necessity of good quality research for concluding a consensus of exercise intervention.

Home Exercise Programs Are Infrequently Prescribed in Trials of Supervised Exercise for Individuals With Low Back Pain: A Scoping Review of 292 Randomized Controlled Trials

OBJECTIVES: To (1) determine how often home exercise programs (HEPs) are prescribed in supervised exercise trials for low back pain (LBP) and (2) describe characteristics of the HEP programs (design, purpose, dose, and adherence). DESIGN: Scoping review. LITERATURE SEARCH: PubMed, CINAHL, and Ovid MEDLINE were searched from January 1, 2010, to August 17, 2021. STUDY SELECTION CRITERIA: Randomized controlled trials that included adults with LBP who received exercise interventions. DATA SYNTHESIS: The presence or absence of a prescribed HEP and any details of the HEP including design, dose, and adherence were extracted and summarized. RESULTS: Of 2689 potentially relevant trials, 292 were eligible for inclusion. Ninety-four trials (32%) included a HEP. The most commonly prescribed home exercises were core stability, trunk strengthening, and motor control exercises. There was great variation in the frequency and duration with which HEPs were prescribed. Adherence to HEPs was measured in fewer than half of the trials, and the methods for measuring adherence were inconsistent. Adherence to HEPs ranged from 29% to 82% in the 21 trials that reported adherence. CONCLUSION: Home exercise programs are not regularly prescribed in supervised exercise trials for LBP. There was considerable variation in prescribing HEPs and monitoring exercise adherence in trials of exercise-based treatments for adults with LBP. There is no consistent method used to measure participants' adherence to HEPs, and adherence percentages vary widely. J Orthop Sports Phys Ther 2023;53(3):120-142.

Effectiveness of Pain Neuroscience Education in Patients with Chronic Musculoskeletal Pain and Central Sensitization: A Systematic Review

OBJECTIVE

To collect the available evidence about the effectiveness of pain neuroscience education (PNE) on pain, disability, and psychosocial factors in patients with chronic musculoskeletal (MSK) pain and central sensitization (CS).

METHODS

A systematic review was conducted. Searches were performed on Pubmed, PEDro, and CINAHL, and only randomized controlled trials (RCTs) enrolling patients ≥18 years of age with chronic MSK pain due to CS were included. No meta-analysis was conducted, and qualitative analysis was realized.

RESULTS

15 RCTs were included. Findings were divided for diagnostic criteria (fibromyalgia-FM, chronic fatigue syndrome-CFS, low back pain-LBP, chronic spinal pain-CSP). PNE has been proposed as a single intervention or associated with other approaches, and different measures were used for the main outcomes considered. Conclusions, practice implication: PNE is effective in improving pain, disability, and psychosocial factors in patients with fibromyalgia, chronic low back pain (CLBP)-especially if associated with other therapeutic approaches-and also in patients with CFS and CSP. Overall, PNE seems to be more effective when proposed in one-to-one oral sessions and associated with reinforcement elements. However, specific eligibility criteria for chronic MSK pain due to CS are still lacking in most RCTs; therefore, for future research, it is mandatory to specify such criteria in primary studies.

Adherence and Effect of Home-Based Rehabilitation with Telemonitoring Support in Patients with Chronic Non-Specific Low Back Pain: A Pilot Study

Home-based exercises have been on the rise recently. This pilot study aimed to assess the adherence and effect of a home-based rehabilitation programme using telemonitoring in patients with chronic non-specific low back pain (CNLBP). Twenty-seven patients with CNLBP were enrolled in the study, each of whom underwent a neurological assessment, including patient-oriented measures and a functional assessment-a battery of tests that comprehensively evaluated trunk muscle function. The rehabilitation programme lasted 18 weeks and included daily home-based exercises. A mobile application or an exercise diary was used to monitor compliance. Adherence to the programme was excellent for both the diary and mobile application groups, with 82.3% in the diary group exercising at least once a day and 72.9% twice a day, and 94.8% in the mobile application group exercising at least once a day and 86.6% twice a day. Both patient-oriented and functional outcomes improved significantly; however, the relative changes of the parameters in these two groups did not correlate, which supports the idea that trunk muscle function does not directly relate to patient complaints and that CNLBP is a multifactorial issue. This model of rehabilitation programme should be used in clinical practice, as its adherence and effectiveness seem noticeable.

Interdisciplinary Co-Design Research Practice in the Rehabilitation of Elderly Individuals with Chronic Low Back Pain from a Senior Care Center in South Korea

The rehabilitation practices encounter multifaceted problems inherent in the current context of the elderly with chronic low back pain (LBP). We addressed a particular multifaceted problem in the current context using an interdisciplinary co-design research practice that consists of three phases: context exploration, patient-expert interaction, and patient-centered rehabilitation. Using an empirical study integrated with this practice, we investigated 30 Korean elderly patients suffering from LBP and introduced an exercise program design. In the context exploration phase, we found that the elderly patients neglected proper posture during work causing spine instability and resultantly developing chronic LBP. The patient–expert interaction phase explored latissimus dorsi (LD) and lumbar erector spinae (LES) muscles as the back trunk muscles that had caused LBP in most of these elderly patients. In the patient-centered rehabilitation phase, we designed an exercise program with exercise protocols and an exercise object for flexion and extension of trunk muscle relaxation and stabilization. Using electromyography (EMG), we found that the exercise program significantly increased the muscle activation levels of the muscles and reduced LBP. Our practice defines and addresses a multifaceted problem with several challenges both in healthcare design and the problem itself. This integrated approach can easily be expanded and adapted to other domain-related research projects that possess characteristics of complex problems.

Clinical outcomes one year after a digital musculoskeletal (MSK) program: an observational, longitudinal study with nonparticipant comparison group

Background

The evidence base for the impact of digital health on musculoskeletal (MSK) outcomes is growing, but it is unclear how much digital MSK programs address pain and function in the intermediate and long term.

Methods

This observational study of digital MSK program participants versus nonparticipants (n = 2570) examined pain, function, depression, and anxiety at 3, 6, and 12 months, and health care use at 12 months. The intervention group engaged in a digital MSK program that included exercise, education, and coaching for at least 3 months. The nonparticipant group registered, but never started the program. We collected data in app or by emailed survey at 3, 6, and 12 months after registering for the program. We conducted descriptive analyses and unadjusted and adjusted regression modeling.

Results

The odds ratio of achieving a minimally clinically important difference (MCID) in pain improvement for the intervention versus the nonparticipant group was 1.97 (95% CI: 1.28, 3.02; p = .002) at 3 months, 1.44 (95% CI: 0.91, 2.25; p = .11) at 6 months, and 2.06 (95% CI: 1.38, 3.08; p = .004) at 12 months in adjusted models. The odds ratio of achieving a MCID in functional improvement for the intervention versus the nonparticipant group was 1.56 (95% CI: 1.03, 2.38; p = .01) at 3 months, 1.55 (95% CI: 1.02, 2.37; p = .04) at 6 months, and 1.35 (95% CI: 0.89, 2.06, p = 0.16) at 12 months in adjusted models. For those with moderate to severe depression or anxiety at baseline, we observed statistically significant lower odds of moderate to severe depression or anxiety at 3 months, 6 months, and 12 months for the intervention versus the nonparticipant group in adjusted models (p < .05). At 12 months, the percentage with invasive, imaging, and conservative services was higher for the nonparticipant versus intervention group by 5.7, 8.1, and 16.7 percentage points, respectively (p < 0.05).

Conclusions

A digital MSK program may offer participants sustained improvement in pain, depression, and anxiety with concomitant decreases in health care use.

Mesenchymal Stem Cell-Derived Exosomes as a Novel Strategy for the Treatment of Intervertebral Disc Degeneration

Intervertebral disc degeneration (IVDD) has been reported to be the most prevalent contributor to low back pain, posing a significant strain on the healthcare systems on a global scale. Currently, there are no approved therapies available for the prevention of the progressive degeneration of intervertebral disc (IVD); however, emerging regenerative strategies that aim to restore the normal structure of the disc have been fundamentally promising. In the last decade, mesenchymal stem cells (MSCs) have received a significant deal of interest for the treatment of IVDD due to their differentiation potential, immunoregulatory capabilities, and capability to be cultured and regulated in a favorable environment. Recent investigations show that the pleiotropic impacts of MSCs are regulated by the production of soluble paracrine factors. Exosomes play an important role in regulating such effects. In this review, we have summarized the current treatments for disc degenerative diseases and their limitations and highlighted the therapeutic role and its underlying mechanism of MSC-derived exosomes in IVDD, as well as the possible future developments for exosomes.
