Functional assessment in patients with castration-resistant prostate cancer treated with darolutamide: results from the DaroAcT study.

BACKGROUND: Androgen receptor inhibitors (ARIs) are approved for the treatment of advanced prostate cancer; however, some patients may experience symptoms and side effects that hinder their physical functioning. The Timed Up and Go (TUG) and Short Physical Performance Battery (SPPB) tests are used to assess physical functioning in older adults and are recommended assessments for patients with prostate cancer, despite lacking validation in this setting. METHODS: DaroAct (NCT04157088) was an open-label, multicenter, phase 2b study designed to evaluate the effects of the ARI darolutamide (lead-in phase) and darolutamide vs enzalutamide (randomized phase) on physical functioning in men with castration-resistant prostate cancer (CRPC). Only the lead-in phase, in which participants received darolutamide 600 mg twice daily, was completed. The TUG and SPPB tests were used to assess physical functioning. RESULTS: The lead-in phase enrolled 30 participants. During 24 weeks of treatment, 8 (32.0%) of 25 evaluable participants exhibited clinically meaningful worsening in TUG from baseline (primary endpoint). At the week 24 visit, 5 (21.7%) of 23 participants had worsening in TUG time, and 8 (33.3%) of 24 participants had worsening in SPPB score. Because only 48% of participants had the same outcome on the TUG and SPPB tests, the study was terminated without initiating the randomized comparison. CONCLUSION: Most participants showed no clinically meaningful worsening in physical functioning after 24 weeks of darolutamide treatment, but poor agreement between tests was observed. Tools to accurately and consistently measure the impact of ARIs on physical functioning in patients with CRPC are needed.

Chemokine CXCL9, a marker of inflammaging, is associated with changes of muscle strength and mortality in older men.

Our study examined associations of the CXC motif chemokine ligand 9 (CXCL9), a pro-inflammatory protein implicated in age-related inflammation, with musculoskeletal function in elderly men. We found in certain outcomes both cross-sectional and longitudinal significant associations of CXCL9 with poorer musculoskeletal function and increased mortality in older men. This requires further investigation. PURPOSE: We aim to determine the relationship of (CXCL9), a pro-inflammatory protein implicated in age-related inflammation, with both cross-sectional and longitudinal musculoskeletal outcomes and mortality in older men. METHODS: A random sample from the Osteoporotic Fractures in Men (MrOS) Study cohort (N = 300) was chosen for study subjects that had attended the third and fourth clinic visits, and data was available for major musculoskeletal outcomes (6 m walking speed, chair stands), hip bone mineral density (BMD), major osteoporotic fracture, mortality, and serum inflammatory markers. Serum levels of CXCL9 were measured by ELISA, and the associations with musculoskeletal outcomes were assessed by linear regression and fractures and mortality with Cox proportional hazards models. RESULTS: The mean CXCL9 level of study participants (79.1 ± 5.3 years) was 196.9 ± 135.2 pg/ml. There were significant differences for 6 m walking speed, chair stands, physical activity scores, and history of falls in the past year across the quartiles of CXCL9. However, higher CXCL9 was only significantly associated with changes in chair stands (ß = - 1.098, p < 0.001) even after adjustment for multiple covariates. No significant associations were observed between CXCL9 and major osteoporotic fracture or hip BMD changes. The risk of mortality increased with increasing CXCL9 (hazard ratio quartile (Q)4 vs Q1 1.98, 95% confidence interval 1.25-3.14; p for trend < 0.001). CONCLUSIONS: Greater serum levels of CXCL9 were significantly associated with a decline in chair stands and increased mortality. Additional studies with a larger sample size are needed to confirm our findings.

Physical performance and sarcopenia assessment in patients with a recent fracture visiting the Fracture Liaison Service.

Impaired physical performance is associated with increased fracture risk. Performance on four physical functioning tests and prevalence of sarcopenia were assessed for 1789 fracture patients and compared to reference data. Performance was low on all tests, especially for patients with a hip, major or ≥ 1 prevalent vertebral fracture. PURPOSE INTRODUCTION: Impaired physical performance and sarcopenia are associated with increased fracture risk. This study aims to assess physical performance and the prevalence of sarcopenia in patients with a recent clinical fracture attending the Fracture Liaison Service (FLS) compared to population means. METHODS: In this cross-sectional study, chair stand test (CST), handgrip strength (HGS), timed-up-and-go (TUG), 6-min walking-test (6MWT), and sarcopenia (following EWGSOP2) were assessed. The proportion of patients with impaired/poor performance compared to reference data was calculated (Z-score: ≥ - 2SD to < - 1 (impaired) and < - 2 SD (poor)). Associations of fracture type, sex, age, and time since fracture with Z-scores were assessed using linear regression analyses. RESULTS: A total of 1789 consecutive FLS patients were included (median age (IQR): 66 (59-74), 70.7% females, 3.9 (± 1.6) months after fracture). The prevalence of impaired/poor performance for CST, HGS, TUG, and 6MWT was 39.2%, 30.4%, 21.9%, and 71.5%, respectively (expected proportion of 16%) and 2.8% had sarcopenia. Lower Z-scores (P < 0.001) were found for hip, major, and ≥ 1 prevalent vertebral fracture (VF) in CST (major: regression coefficient (B) (95%CI) = - 0.25 [- 0.34, - 0.16]; hip: B = - 0.32 [- 0.47, - 0.17], VF: B = - 0.22 [- 0.34, - 0.11]), TUG; (major: B = - 0.54 [- 0.75, - 0.33]; hip: B = - 1.72 [- 2.08, -1.35], VF: B = - 0.61 [- 0.88, - 0.57]), 6MWT (major: B = - 0.34 [- 0.47, - 0.21]; hip: B = - 0.99 [- 1,22, - 0.77], VF: B = - 0.36 [- 0.53, - 0.19]). CONCLUSIONS: Physical performance is significantly lower in FLS patients compared to healthy peers, especially in patients with hip, major or prevalent VF. These findings underline the need to assess and improve the physical performance of FLS patients, despite a low prevalence of sarcopenia.

Quality of life in patients with nasopharyngeal carcinoma receiving IMRT vs IMPT: a multicenter prospective longitudinal study.

PURPOSE: Nasopharyngeal carcinoma (NPC) patients may experience symptom distress and depression during and after radiation therapy, which negatively impacts quality of life (QOL). We sought to identify trajectories of symptom distress, depression, social support, and QOL in patients with NPC receiving intensity-modulated radiation therapy (IMRT) vs intensity-modulated proton therapy (IMPT). METHODS: A multicenter prospective longitudinal study recruited NPC patients from two leading medical centers in Taiwan. The 121 NPC patients were followed from before RT (T0), at 4 weeks after beginning RT (T1), at 6 weeks of RT or the end of treatment (T2), and at 4 weeks post-RT (T3). Generalized estimating equation analysis was used to identify the factors related to QOL. RESULTS: Patients' symptom distress and depression increased from T0, peaked at T2, and decreased at T3. Physical-QOL and psychosocial-QOL decreased from T0 to T2, then increased by T3. Patients who had early-stage cancer, received a lower RT dose, had less symptom distress, and had less depression were more likely to have better QOL. Greater physical-QOL was associated with IMPT receipt, higher education level, early cancer stage, lower radiation dose, less symptom distress, and less depression. Patients who had good physical performance, received a lower radiation dose, had less symptom distress, and had less depression were more likely to have better psychosocial-QOL. CONCLUSION: Radiation dose, symptom distress, and depression were the most important factors affecting QOL in patients with NPC. Understanding the factors associated with the trajectory of QOL can guide care during radiation treatment.

Association of Race, Ethnicity, and Gender to Disparities in Functional Recovery and Social Health After Major Lower Limb Amputation: A Cross-sectional Pilot Study.

OBJECTIVE: To assess if evidence of disparities exists in functional recovery and social health post-lower limb amputation. DESIGN: Race-ethnicity, gender, and income-based group comparisons of functioning and social health in a convenience sample of lower limb prosthetic users. SETTING: Prosthetic clinics in 4 states. PARTICIPANTS: A geographically diverse cohort of 56 English and Spanish speaking community-dwelling individuals with dysvascular lower limb amputation, between 18-80 years old. INTERVENTIONS: None. MAIN OUTCOMES MEASURES: Primary outcomes included 2 physical performance measures, the Timed Up and Go test and 2-minute walk test, and thirdly, the Prosthetic Limb Users Survey of Mobility. The PROMIS Ability to Participate in Social Roles and Activities survey measured social health. RESULTS: Of the study participants, 45% identified as persons of color, and 39% were women (mean ± SD age, 61.6 (9.8) years). People identifying as non-Hispanic White men exhibited better physical performance than men of color, White women, and women of color by -7.86 (95% CI, -16.26 to 0.53, P=.07), -10.34 (95% CI, -19.23 to -1.45, P=.02), and -11.63 (95% CI, -21.61 to -1.66, P=.02) seconds, respectively, on the TUG, and by 22.6 (95% CI, -2.31 to 47.50, P=.09), 38.92 (95% CI, 12.53 to 65.30, P<.01), 47.53 (95% CI, 17.93 to 77.13, P<.01) meters, respectively, on the 2-minute walk test. Income level explained 14% and 11% of the variance in perceived mobility and social health measures, respectively. CONCLUSIONS: Study results suggest that sociodemographic factors of race-ethnicity, gender, and income level are associated with functioning and social health post-lower limb amputation. The clinical effect of this new knowledge lies in what it offers to health care practitioners who treat this patient population, in recognizing potential barriers to optimal recovery and quality of life. More work is required to assess lived experiences after amputation and provide better understanding of amputation-related health disparities.

Home-based Rehabilitation After Inpatient Rehabilitation: Utilization Rate and Characteristics of Referred Patients.

OBJECTIVE: To determine the utilization rate of a home-based rehabilitation program after an inpatient rehabilitation stay, and to investigate the profile of users. DESIGN: Observational study. SETTING: Inpatient rehabilitation facility in a tertiary hospital. PARTICIPANTS: Older patients (N=1913) discharged home between June 2018 and May 2021, after an inpatient rehabilitation stay. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Discharge to home-based rehabilitation. RESULTS: Over the study period, 296 (15.5%) patients were discharged to home-based rehabilitation. Compared with the others, home-based rehabilitation patients were more frequently women (69.6% vs 61.5%; P=.008), and admitted after orthopedic surgery (elective or for fracture) (30.1% vs 16.1%; P<.001). They had worse functional performance at admission (mean Functional Independence Measure self-care score: 27.8±7.3 vs 30.8±6.7; P<.001), but greater gain in self-care during their inpatient stay (5.0±4.8 vs 4.4±4.7; P=.038). In multivariable analysis, being a woman (adjusted odds ratio [adjOR], 1.36; 95% confidence interval [CI], 1.01-1.82; P=.040), being admitted after orthopedic surgery (adjOR, 2.32; 95% CI, 1.64-3.27; P<.001), being admitted for gait disorders or falls (adjOR, 1.38; 95% CI, 1.01-1.88; P=.039), and showing greater gain in mobility during the inpatient stay (adjOR, 1.12; 95% CI, 1.07-1.17; P<.001) remained associated with discharge to home-based rehabilitation. In contrast, higher mobility at discharge decreased the odds of discharge to home-based rehabilitation (adjOR, 0.87; 95% CI, 0.83-0.91; P<.001). CONCLUSIONS: One in 6 patients benefited from home-based rehabilitation after their inpatient stay. Although these patients had poorer functional performance at admission and discharge, they showed greater mobility improvement during their inpatient stay, suggesting that their good recovery potential was a key determinant of their orientation toward home-based rehabilitation.

The Effect of Proprioceptive Training on Hand Function and Activity Limitation After Open Carpal Tunnel Release Surgery: A Randomized Controlled Study.

OBJECTIVE: To investigate the effect of proprioceptive training on hand function and activity limitation in patients undergoing open carpal tunnel release surgery. DESIGN: Randomized controlled study. SETTING: A university hospital. PARTICIPANTS: Thirty patients were included in the study and randomized to proprioceptive training (PT) and conventional rehabilitation (CR) groups. INTERVENTION: One week after surgery, both groups received CR for 6 weeks. All participants were asked to perform home-based exercises daily in 3 sets with 10 repetitions. For the PT group, a 6-step PT program was conducted starting from Week 6. Both groups received face-to-face interventions twice a week for 12 weeks. MAIN OUTCOME MEASURES: The outcome measures included the Purdue Pegboard Test (PPT), the joint position sense test (JPST), the Boston Carpal Tunnel Questionnaire, and the Patient-Specific Functional Scale. In total, 3 assessments were performed (at 1, 6 and 12 weeks postoperatively). RESULTS: In the PT group, the results for PPT were statistically significant (P<.05). Although there was a greater decrease in the absolute angular error value (JPST) of the PT group compared to the CR group, the difference was nonsignificant (P>.05). Similar reductions in activity limitation were seen in both groups (PT: 176%, CR: 175%). Symptom severity decreased by 40% in the PT group vs 32% in the CR group. The effect sizes were larger for the changes between the second and third assessments in the PT group compared to the CR group in all parameters tested. CONCLUSION: When applied after carpal tunnel release surgery, PT may potentially to improve hand functions, reduce activity limitation, increase participation in activities of daily living, and thus improve quality of life.

Construct Validity and Responsiveness of Performance-based Tests in Individuals With Knee Osteoarthritis.

OBJECTIVES: To assess the construct validity and responsiveness of 3 performance-based tests in individuals with knee osteoarthritis (KOA). DESIGN: This study has a prospective cohort design. SETTING: Assessments were administered at the Federal University of São Carlos (Brazil) by 3 different raters. PARTICIPANTS: A total of 107 participants with KOA were aged ≥40 years (N=107). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: This study assessed the construct validity and responsiveness of 3 performance-based tests: 40-meter fast-paced walk test (40-m FPWT), 11-step stair climb test (11-step SCT), and 30-second chair stand test (30-s CST). The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Knee Injury and Osteoarthritis Outcome Score (KOOS), sedentary behavior (activPAL), and numeric pain rating scale (NPRS) were used as comparator instruments. Measurements were obtained at baseline and after 6 months. The construct validity and responsiveness were calculated using Spearman correlation coefficient within predefined hypotheses based on a panel comprising 5 experts in the field of outcome measurement in KOA. RESULTS: The three performance-based tests showed excellent (ICC>0.9) reliability (intra and inter); however, only the 40-m FPWT and 11-step SCT were considered valid and responsive because both confirmed >75% of the priori hypotheses. The 30-s CST was not considered valid or responsive because it has not confirmed ≥75% of the priori hypotheses. CONCLUSION: The 3 performance-based tests are reliable for intra and inter assessments. The 40-m FPWT and 11-step SCT are both valid and responsive for measuring physical function in patients with KOA. The 30-s CST was not considered valid or responsive. Therefore, 40-m FPWT and 11-step SCT can detect changes over time and are indicated for functional assessment in clinical practice.

Assessment of Mobility Trajectories Using Wearable Inertial Sensors During Autologous Hematopoietic Cell Transplant.

OBJECTIVE: This study aimed to characterize mobility patterns using wearable inertial sensors and serial assessment across autologous hematopoietic cell transplant (autoHCT) and investigate the relation between mobility and perceived function in patients with hematologic cancer. DESIGN: Prospective longitudinal study. SETTING: Hospital adult transplant clinic followed by discharge. PARTICIPANTS: 78 patients with hematological cancer receiving autoHCT. MAIN OUTCOME MEASURES: Mobility was measured across 3 clinical phases (pretransplant, pre-engraftment, and post-engraftment) in using inertial sensors worn during prescribed performance tests in the hospital. Perceived function was assessed using validated provider-reported (Eastern Cooperative Oncology Group [ECOG] Performance Status Scale) and patient-reported [European Organization for Research and Treatment of Cancer Quality of Life Questionnaire [EORTC QLQ-C30]) measures. Trajectories of 5 selected mobility characteristics (turn duration, gait speed, stride time variability, double support time, and heel strike angle) across the clinical phases were also evaluated using piecewise linear mixed-effects models. RESULTS: Using Principal Components Analysis, 4 mobility patterns were identified pretransplant: Gait Limitation, Sagittal Sway, Coronal Sway, and Balance Control. Gait Limitation measured pretransplant was significantly inversely associated with perceived function reported by the provider- (ß = -0.11; 95% CI: -0.19, -0.02) and patient- (ß = -4.85; 95% CI: -7.72, -1.99) post-engraftment in age-adjusted linear regression models. Mobility characteristics demonstrated immediate declines early pre-engraftment with stabilization by late pre-engraftment. CONCLUSION: Patients with hematological cancer experiencing gait limitations pretransplant are likely to have worse perceived function post-engraftment. Mobility declines in early phases post-transplant and may not fully recover, indicating an opportunity for timely rehabilitation referrals. Wearable inertial sensors can be used to identify early mobility problems and patients who may be at risk for future functional decline who may be candidates for early physical rehabilitation.

Promoting meaningful activities by occupational therapy in elderly care in Belgium: the ProMOTE intervention.

BACKGROUND: Older people want to age in place. Despite advancing functional limitations and their desire of aging in place, they are not always faithful to therapy that maintains independence and promotes safety. Occupational therapists can facilitate aging in place. Occupational therapy is defined as the therapeutic use of everyday life occupations with persons, groups, or populations for the purpose of enhancing or enabling participation. AIM: To describe the content a high-adherence-to-therapy and evidence-based occupational therapy intervention to optimize functional performance and social participation of home-based physically frail older adults and wellbeing of their informal caregiver, and the research activities undertaken to design this intervention. METHODS: A roadmap was created to develop the occupational therapy intervention. This roadmap is based on the Medical Research Council (MRC) framework and is supplemented with elements of the Intervention Mapping approach. The TIDieR checklist is applied to describe the intervention in detail. A systematic review and two qualitative studies substantiated the content of the intervention scientifically. RESULTS: The application of the first two phases of the MRC framework resulted in the ProMOTE intervention (Promoting Meaningful activities by Occupational Therapy in Elderly). The ProMOTE intervention is a high-adherence-to-therapy occupational therapy intervention that consists of six steps and describes in detail the evidence-based components that are required to obtain an operational intervention for occupational therapy practice. CONCLUSION: This study transparently reflects on the process of a high-quality occupational therapy intervention to optimize the functional performance and social participation of the home-based physically frail older adult and describes the ProMOTE intervention in detail. The ProMOTE intervention contributes to safely aging in place and to maintaining social participation. The designed intervention goes beyond a description of the 'what'. The added value lies in the interweaving of the 'why' and 'how'. By describing the 'how', our study makes the concept of 'therapeutic use-of-self' operational throughout the six steps of the occupational therapy intervention. A further rigorous study of the effect of the ProMOTE intervention on adherence, functional performance and social participation is recommended based to facilitate the implementation of this intervention on a national level in Belgium.

An engineered glove to follow finger function in rheumatoid arthritis: an observational prospective study.

The engineered Hand Test System (HTS) glove has shown high reliability in assessing the baseline functional status of rheumatoid arthritis (RA) hand. Starting from this achievement, the aim of the present observational prospective study was to assess the functionality of the single fingers of rheumatoid hand at follow-up. Eighty RA patients performed HTS glove tests at baseline and among these fifty-six patients were re-tested after 7 months. The HTS glove parameters [Touch Duration (TD), Movement Rate (MR), Inter Tapping Interval (ITI)] were correlated with disease activity and disability clinimetric indexes [Disease Activity Score 28 joint count-C-reactive protein (DAS28-CRP), Clinical Disease Activity Index (CDAI), Simplified Disease Activity Index (SDAI), Health Assessment Questionnaire-Disability Index (HAQ-DI), grip strength, visual analogue scale of pain (VAS), patient global assessment (PGA)], and with laboratory values. HTS glove parameters (TD, ITI, and MR) showed statistically significant correlations with clinimetric and clinical indexes at both time points (p < 0.05). During follow-up, a statistically significant variation of all HTS glove parameters for the fingers that have performed both the worst or best HTS test at baseline was detected (p < 0.05), while the mean HTS glove parameter values by considering all fingers did not show a statistically significant variation over time, as well as the traditional clinimetric indexes. Besides the objective role in assessing the RA hand function by integrating the traditional clinimetric indexes, the HTS glove seems a useful tool for evaluating worst or best finger function during time by measuring the movement speed.

Sex differences in physical functioning among older adults: cross-sectional results from the OUTDOOR ACTIVE study.

BACKGROUND: Maintaining good functional ability is a key component of healthy ageing and a basic requirement for carrying out activities of daily living, staying independent, and delaying admission to a nursing home. Even though women have a higher life expectancy and slower age-related muscle mass loss than men, they often show a higher prevalence of limitations in physical functioning. However, the reasons behind these sex differences are still unclear. Therefore, the aims of this study were to investigate sex differences among older adults regarding physical functioning and to study which factors are explaining these sex differences. METHODS: Cross-sectional data from participants of the OUTDOOR ACTIVE study residing in Bremen, Germany, aged 65 to 75 years, were included in the analyses. Physical functioning was assessed via a self-administered questionnaire using the SF-36 10-item Physical Functioning Scale. Social, lifestyle, and health-related factors were also assessed using the questionnaire. Physical activity was measured objectively using wrist-worn accelerometers over seven consecutive days. Descriptive analyses with absolute and relative frequencies, means and standard deviations, as well as T-tests and chi-square tests were carried out. To test for associations between sex, physical functioning, and several individual factors, linear regressions were performed. RESULTS: Data of 2 141 participants (52.1% female) were included in the study. Women and men showed statistically significant differences in physical functioning, with men perceiving fewer limitations than women. On average, women had a physical functioning score of 81.4 ± 19.3 and men 86.7 ± 17.0. Linear regression showed a statistically significant negative association between physical functioning score and sex (ß: -0.15, 95% CL: -0.19, -0.10). The association remained statistically significant when adding individual factors to the model. All factors together were only able to explain 51% of the physical functioning-sex association with health indicators and the presence of chronic diseases being the most influential factors. CONCLUSIONS: We found sex differences in physical functioning, with older women having more limitations than older men. The results showed that health-related factors and chronic diseases played the biggest roles in the different physical functioning scores of women and men. These findings contribute to future longitudinal, more in-depth research. TRIAL REGISTRATION: German Clinical Trials Register DRKS00015117 (Date of registration 17-07-2018).

Assessment of non-communicable disease risk factors, functional performance, and health-related quality of life in adults: a comparative analysis in low-resourced urban and rural areas of South Africa.

BACKGROUND: Globally, disparities between non-communicable disease (NCD) risk factors, functional performance, and health-related quality of life (HRQoL) exist in people living in rural and low-resourced urban settings. Evidence of these health differences determined with objective NCD risk factors and functional performance measurements in South Africa, is scarce. Therefore, the study aimed to determine the differences in NCD risk factors, functional performance and HRQoL between rural and low-resourced urban areas. METHODS: The study recruited 311 adults (35-80 years) presenting with at least one NCD risk factor from low-resourced urban- (n = 183) and rural (n = 128) communities. Objective measurements of physical activity (PA) by means of combined heart rate and accelerometery, body composition employing skinfolds, peripheral lipid and glucose concentrations, blood pressure, functional performance indicators (handgrip, single leg stand, sit-to-stand, timed-up-and-go speed, predicted peak VO2 max); and HRQoL were measured according to standard procedures. Independent t-tests, Mann-Whitney U, and chi-square tests were performed to determine differences between the variables of low-resourced urban and rural settings. RESULTS: The participants from the low-resourced urban setting were significantly older than the rural residents (59.1 ± 10.7 years vs. 52.8 ± 11.3 years; p = 0.001). NCD risk factors were significantly more prevalent in the low-resourced urban participants compared to rural participants, in particular for elevated systolic (85.8% vs. 62.5%; p = 0.001), and diastolic blood pressure (88.5% vs. 65.6%; p = 0.001), physical inactivity (95.9% vs. 87.7%; p = 0.026), increased cholesterol concentrations (22.1% vs. 8.7%; p = 0.002), and increased waist circumference (61.9% vs. 49.2%; p = 0.027). Low-resourced urban residents presented with a higher average body fat percentage (27.69% ± 7.65% vs. 12.23% ± 4.67%; p < 0.001), and lower moderate to vigorous PA levels (37.19 ± 49.55 [95% CI = 29.12-45.27] vs. 62.92 ± 60.43 min/week [95% CI = 47.95-77.90]; p = 0.003) compared to rural residents. Rural residents showed significantly better functional performance, including peak VO2 (23.99 ± 9.89 vs. 16.95 ± 7.64 ml/min/kg; p = 0.001) and single leg stand (right leg: 44.96 ± 18.47 vs. 20.87 ± 19.18 s; p = 0.001) as well as higher HRQoL for the physical (51.06 ± 8.14% vs. 45.62 ± 11.13%; p < 0.001) and mental (54.75 ± 8.24% vs. 48.91 ± 12.27%; p < 0.001) component scores compared to participants from the low-resourced urban areas. CONCLUSION: NCD risk factors, functional performance, and HRQoL significantly differ in rural communities compared to low-resourced urban communities in South Africa. Urban areas' most prevalent risk factors were elevated blood pressure, physical inactivity, and increased waist circumference. Participants from rural areas demonstrated significantly better functional performance, such as fitness and balance. HRQoL was better in rural settings than in urban settings. Future intervention programmes should be tailored for specific settings.

Effectiveness of guided telerehabilitation on functional performance in community-dwelling older adults: A systematic review.

OBJECTIVE: To systematically review the effectiveness of guided telerehabilitation on improving functional performance in community-dwelling older adults. DATA SOURCES: Articles published in PubMed, Cochrane Library and Embase (Ovid) from 01 January 2010 up to 17 October 2023. REVIEW METHODS: Included studies had (1) a randomised controlled trial design, (2) an average population age of 65 years or older, (3) a home-based setting and (4) evaluated the effectiveness of functional performance outcome measures. The intervention was considered telerehabilitation when guided by a healthcare professional using video, audio and/or text communication technologies with a minimum frequency of once per week. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis 2020 statement guideline was followed. Methodological quality was appraised using the revised Cochrane Risk of Bias tool. RESULTS: A total of 26 randomised controlled trials were included. Telerehabilitation had superior (N = 15), non-superior (N = 16) or non-inferior (N = 11) effectiveness for improving functional performance outcome measures compared to control interventions. No studies found the control intervention to be superior over telerehabilitation. Between study differences in intervention characteristics contributed to significant clinical heterogeneity. Five studies were found to present an overall 'low' risk of bias, 12 studies to present 'some' risk of bias and 9 studies to present an overall 'high' risk of bias. CONCLUSION: The findings suggest that telerehabilitation could be a promising alternative to in-person rehabilitation for improving functional performance in community-dwelling older adults. Additional well-designed studies with minimised bias are needed for a better understanding of effective telerehabilitation intervention strategies.

Comparison of functional performance outcomes between oral patented crystalline glucosamine sulfate and platelet-rich plasma among knee osteoarthritis patients: a propensity score matching analysis.

BACKGROUND: Among the medications used to treat knee osteoarthritis (OA), oral patented crystalline glucosamine sulfate (pCGS) and platelet-rich plasma (PRP) have become popular alternatives to painkillers or nonsteroidal anti-inflammatory drugs (NSAIDs). Although studies have shown that pCGS and PRP improve clinical outcomes, no study has compared outcomes between these optional treatments. We compared functional performance outcomes from baseline to the 1-year follow-up (FU) between oral pCGS and PRP in patients with knee OA. MATERIALS AND METHODS: Three hundred eighty-two patients receiving oral pCGS and 122 patients receiving PRP injections were enrolled for a review of functional performance outcomes, including a five-time sit-to-stand test (5xSST), time up-and-go test (TUGT), and 3-minute walk distance test (3MWDT). The patients were followed up for one year. The pCGS group received 1500 mg daily, whereas the PRP group received 2 cycles of intra-articular injections at week 0 and week 6. Using propensity score matching based on age, sex, height, weight, BMI, and Kellgren and Lawrence (KL) classification, all three functional performance outcomes were compared between the baseline (pretreatment), 6-week, 12-week, 24-week, and 1-year FUs. RESULTS: With a ratio of 2:1 (pCGS: PRP), 204 patients in the pCGS group were matched with 102 patients in the PRP group. Compared with the baseline levels, the PRP group showed significant improvements in 5xSST and TUGT outcomes from 6 weeks and significant improvements in 3MWDT outcomes from 12 weeks, whereas the pCGS group showed significant improvements in TUGT outcomes from 6 weeks and significant improvements in 5xSST and 3MWDT outcomes from 12 weeks. At the 24-week and 1-year FU, both groups showed significant improvements in all three functional performance tests without adverse events. CONCLUSIONS: Although the PRP group showed faster improvements in 5xSST outcomes at six weeks, from the 12-week to 1-year FU, both the pCGS and PRP groups showed significant improvements in 5xSST, TUGT, and 3MWDT outcomes. As the use of PRP is more complicated and invasive than the use of oral pCGS, the benefits and drawbacks of selecting PRP over pCGS in knee OA treatment should be examined.

Relationship between severity of concussion's symptoms and functional performance in children.

INTRODUCTION: Concussion is a common brain injury that has significant effects on multiple functional domains in children. However, limited research exists on the relationship between concussion severity and functional performance in this population. This study aimed to examine the relationship between the severity of concussion symptoms and children's balance and functional performance. METHODS: This cross-sectional study recruited 23 children (9 males and 14 females; mean age 13.9 ± 2.2 years) with clinically diagnosed concussions from a tertiary balance center in 2016. Participants underwent clinical and functional evaluations by specialized physical therapists. Symptom severity was assessed using the Post-Concussion Symptom Scale (PCSS), while functional performance was measured using the Functional Gait Assessment (FGA). RESULTS: There was a trend suggesting a negative correlation between symptom severity (PCSS) and functional performance (FGA), indicating potentially better performance in individuals with milder symptoms. However, this trend was not significant (rs (21) = -.072, p = 0.744). Furthermore, no significant correlation was found between FGA scores and the severity of individual symptoms. CONCLUSION: The findings suggest that concussion symptom severity may not be directly related to functional performance in children. Therefore, it is crucial to incorporate functional performance measures alongside symptom assessment for comprehensive concussion management.

Revolutionizing Sports Rehabilitation: Unleashing the Power of Tele-Rehabilitation for Optimal Physiotherapy Results.

Background: Tele-rehabilitation programs have emerged as a promising approach to improve access to physiotherapy services for athletes with sports-related injuries. This randomized controlled trial aimed to compare the effectiveness of a tele-rehabilitation program with traditional in-person physiotherapy in improving outcomes for this population. Methods: This randomized controlled trial enrolled a large sample of 780 athletes with sports-related injuries to compare the effectiveness of tele-rehabilitation and traditional in-person physiotherapy. Blinding procedures were implemented to minimize bias. The intervention group received tele-rehabilitation physiotherapy, whereas the control group received traditional in-person physiotherapy. Pre- and post-intervention assessments were conducted to measure outcome measures, including range of motion, muscle strength, pain levels, and functional performance. Results: Significant improvements were observed in all outcome measures in both the tele-rehabilitation and in-person groups from baseline to postintervention. Independent t tests demonstrated no significant differences between the two groups in any of the outcome measures. These findings indicate that the tele-rehabilitation program was as effective as traditional in-person physiotherapy in improving the outcomes of athletes with sports-related injuries, even in a large sample size of 780 participants. Conclusion: This study provides robust evidence supporting the feasibility and effectiveness of tele-rehabilitation programs as viable alternatives to traditional in-person physiotherapy for athletes with sports-related injuries. These findings highlight the potential of tele-rehabilitation to significantly expand access to high-quality physiotherapy services for a large number of athletes. Further research should focus on evaluating the long-term effectiveness and cost-effectiveness of tele-rehabilitation programs in sports rehabilitation using larger sample sizes.

Effects of Walking-Only Intervention on Physical Function, Fall-Related Outcomes, and Health-Related Quality of Life in Community-Dwelling Older Adults: A Systematic Review and Meta-Analysis.

This study aimed to determine the effects of walking-only intervention (walking was the only exercise in which people participated) on physical function, fall-related outcomes, and health-related quality of life in community-dwelling older adults. We conducted a systematic search across five electronic databases, assessing risk of bias using Minds Manual for Guideline Development. Meta-analyses were performed, and pooled standardized mean differences were calculated. Nine studies (a total of 1,309 participants) were included, showing that walking-only interventions improved walking endurance (standardized mean difference: 1.11, 95% confidence interval: [0.08, 2.15]) and health-related quality of life (standardized mean difference: 0.71, 95% confidence interval: [0.18, 1.25]). However, there were no significant improvements in other outcomes. The certainty of the evidence based on the Grading of Recommendations, Assessment, Development, and Evaluation approach for all outcomes was graded as very low, primarily due to significant inconsistency and imprecision. Our results suggest that walking-only intervention can be effective for enhancing walking endurance and health-related quality of life for community-dwelling older adults. Further studies are required to investigate the effects of walking-only intervention. This need stems from the limited number of randomized controlled trials, heterogeneous intervention settings and results, and the very low certainty of the evidence.

Lumbar Extensor Muscle Strength and Physical Performance in Community-Dwelling Older Adults: Findings From SarcoSpine Cohort.

BACKGROUND: The lumbar extensor muscles (LEMs) play an important role in body posture and physical function in older adults. Because lumbar extensor strength decreases more rapidly than limb muscle strength with age, it should be evaluated to aid healthy aging. This study investigated the association between LEM strength and physical performance in community-dwelling older adults. METHODS: This prospective observational cohort study of spinal sarcopenia (SarcoSpine) was conducted at a single center. One hundred and ten consecutive individuals who completed the baseline survey, including conventional sarcopenic indices, lumbar spine three-dimensional magnetic resonance imaging, isokinetic lumbar extensor strength, and physical performance tests (Short Physical Performance Battery, Berg Balance Scale, and Back Performance Scale [BPS]), were enrolled. A multivariate linear regression analysis was performed to determine the variables for evaluating their association with LEM strength. RESULTS: Among the conventional sarcopenic indices, gait speed was significantly correlated with Short Physical Performance Battery results and Berg Balance Scale score in men and women. Handgrip strength was significantly correlated with the BPS score for both sexes. In the multivariable linear regression, age (ß = -2.12, p < .01) and BPS score (ß = -3.54, p = .01, R2 = .29) were independent indicators of LEM strength. CONCLUSIONS: Our findings reveal the substantial association between LEM strength and BPS score in older women. The targeted intervention aimed at improving the LEMs strength would be needed to enhance physical performance in the aging population.

Determining the relationship between oral health and physical function in elderly people.

BACKGROUND: Poor oral conditions in the elderly may have numerous effects on general health, including physical fitness and performance. OBJECTIVES: This study aimed to determine the relationship between oral health and physical function in elderly people. METHODS: Physical function and oral health parameters were compared using parametric comparison tests and Pearson correlation analyses. In addition, principal components analysis, hierarchical clustering and multidimensional scaling analysis clustered the patients' physical and oral health scores. The relationship between the groups was also determined using decision tree analysis. RESULTS: A total of 112 elderly patients participated in the study. Grip strength (GS) was higher in patients with high chewing ability, and Timed Up and Go (TUG) scores were lower in the high oral health group (p < .05). GS was correlated with Decay, Missing, and Filled Teeth Index (DMFT) and the number of remaining and functional teeth (p < .05). According to principal component analysis, it was seen that there were three components (oral, functional and quality of life (QoL) parameters), and the features that were related to each other were gathered together. TUG and GS showed the highest relative importance among physical function criteria in the classification based on chewing ability. They were GS and physical activity for oral health-related QoL. CONCLUSION: In the elderly, higher physical function parameters, especially GS may be an indicator of a better oral health and oral health-related QoL. Preventive physical rehabilitation practices, in addition to oral treatments, may be effective in improving oral health in the elderly.
