Virtual reality experiential learning improved undergraduate students' knowledge and evaluation skills relating to assistive technology for older adults and individuals with disabilities.

BACKGROUND: The aging population has caused assistive technology (AT) to receive attention. Thus, ensuring accurate user comprehension of AT has become increasingly crucial, and more specialized education for students in relevant fields is necessary. The goal of this study was to explore the learning outcomes in the context of AT for older adults and individuals with disabilities through the use of VR experiential learning. METHODS: A parallel-group design was used. Sixty third-year university students studying gerontology and long-term-care-related subjects in Taiwan were enrolled, with the experimental (VR) and control (two-dimensional [2D] video) groups each comprising 30 participants. Both groups received the same 15-minute lecture. Subsequently, the experimental group received experiential learning through a VR intervention, whereas the control group watched a 2D video to learn. The students' knowledge of AT was assessed using a pretest and posttest. Additionally, their skills in evaluation of residential environments were assessed using the Residential Environment Assessment (REA) Form for Older Adults. All data analyses were performed with SPSS version 22. RESULTS: In the posttest conducted after the intervention, the experimental group exhibited a significant 20.67 point improvement (p < 0.05), whereas the control group only exhibited improvement of 3.67 points (p = 0.317). Furthermore, the experimental group demonstrated a significantly higher score (+ 2.17 points) on the REA Form for Older Adults than did the control group (p < 0.05). CONCLUSION: VR experiential learning can significantly improve undergraduate students' knowledge and evaluation skills in relation to AT for older adults and individuals with disabilities.

Effectiveness of neuromuscular electrical stimulation in improving mobility in children with cerebral palsy: A systematic review and meta-analysis of randomized controlled trials.

OBJECTIVE: To investigate whether neuromuscular electrical stimulation improves mobility in children with spastic cerebral palsy. METHODS: PubMed, Cochrane, EMBASE, and Scopus were searched for randomized controlled trials studying the effects of NMES on the lower limbs in children with spastic CP. Randomized controlled trials comparing the effect of neuromuscular electrical stimulation with that of placebo or conventional therapy on mobility in children with cerebral palsy were eligible for inclusion. Two reviewers independently screened studies, extracted data, and examined the risk of bias and quality of evidence by using the revised Cochrane Risk-of-Bias Tool for Randomized Trials (RoB 2.0) and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) method. The final search was conducted on May 23, 2022. RESULTS: A total of 14 randomized controlled trials (2 crossover studies and 12 parallel studies including 421 patients) were included in this meta-analysis. Compared with the control group (conventional physical therapy), the treatment group exhibited greater improvement in walking speed (standardized mean difference = 0.29; 95% confidence interval = 0.02-0.57) and the standing, walking, running, and jumping dimension of the Gross Motor Function Measure (standardized mean difference = 1.24; 95% confidence interval = 0.64-1.83). CONCLUSION: Neuromuscular electrical stimulation improved mobility in children with spastic cerebral palsy, particularly in standing, running, and jumping function, and it is safe for children with spastic cerebral palsy.

Upper limb manual training for children with cerebral palsy: A systematic review and network meta-analysis of randomized controlled trials.

OBJECTIVE: There are different upper limb manual training protocols, namely constraint-induced movement therapy, modified constraint-induced movement therapy, hand-arm bimanual intensive training, hand-arm bimanual intensive training including lower extremity, action observation training, and mirror therapy, available for improving functional outcomes in children with cerebral palsy. However, the effect and priority of these strategies remain unclear. DATA SOURCES: We searched the PubMed, Cochrane Library, and Embase databases for relevant articles from inception to October 12, 2022. REVIEW METHODS: To assess the effect and priority of different strategies of upper limb manual training protocols through a systematic review and network meta-analysis of randomized controlled trials. RESULTS: We included 22 randomized controlled trials in this network meta-analysis. The ranking probability and standard mean differences with 95% credible intervals of the comparison between placebo and other forms of upper limb manual training were as follows: mirror therapy = 2.83 (1.78, 3.88), hand-arm bimanual intensive training including the lower extremity = 0.53 (0.09, 0.96), constraint-induced movement therapy = 0.44 (0.18, 0.71), hand-arm bimanual intensive training = 0.41 (0.15, 0.67), modified constraint-induced movement therapy = 0.39 (0.03, 0.74), and action observation training = 0.18 ( - 0.29, 0.65). No significant inconsistency was noted between the results of direct and indirect comparisons. CONCLUSION: We suggest that mirror therapy could be the upper limb manual training protocol of choice for improving functional outcomes in patients with cerebral palsy.

A time-course study of urodynamic analyses in rat models with dopaminergic depletion induced through unilateral and bilateral 6-hydroxydopamine injections.

BACKGROUND: Bladder dysfunction is a common non-motor disorder in Parkinson's disease (PD). This study attempted to determine the bladder dysfunction with disease progression in the PD rat model produced from unilateral/bilateral injections of 6-hydroxydopamine (6-OHDA). METHODS: Cystometrographic (CMG) and external urethral sphincter electromyographic (EUS-EMG) measurements were scheduled in a time-course manner to determine the disease timing, onset, and severity. Animals were allotted into normal control, unilateral, bilateral 6-OHDA injected groups and subjected to scheduled CMG, EUS-EMG analyses at weeks 1, 2, and 4. RESULTS: The urodynamic results concluded that voiding efficiency (VE) was reduced in both unilateral and bilateral PD rats at all-time points. VE had decreased from 57 ± 11% to 31 ± 7% in unilateral PD rats and in bilateral PD rats, a decreased VE of 20 ± 6% was observed compared to control and unilateral PD rats. The EMG results in unilateral PD rats indicated declines in bursting period (BP) (3.78-2.94 s), active period (AP) (93.38-88.75 ms), and silent period (SP) (161.62-114.30 ms). A sudden reduction was noticed in BP (3.62-2.82 s), AP (92.21-86.01 ms), and SP (128.61-60.16 ms) of bilateral PD rats than in control and unilateral PD rats. Histological evidence exhibited a progressive dopaminergic neurons (DA) depletion in the substantia nigra (SN) region in 6-OHDA lesioned rats. CONCLUSION: The experimental outcomes strongly implied that significant variations in bladder function and VE decline were due to the depletion of DA neurons in the SN region of the brain.

Comparative Efficacy of Intra-Articular Injection, Physical Therapy, and Combined Treatments on Pain, Function, and Sarcopenia Indices in Knee Osteoarthritis: A Network Meta-Analysis of Randomized Controlled Trials.

Knee osteoarthritis (KOA) is associated with a high risk of sarcopenia. Both intra-articular injections (IAIs) and physical therapy (PT) exert benefits in KOA. This network meta-analysis (NMA) study aimed to identify comparative efficacy among the combined treatments (IAI+PT) in patients with KOA. Seven electronic databases were systematically searched from inception until January 2023 for randomized controlled trials (RCTs) reporting the effects of IAI+PT vs. IAI or PT alone in patients with KOA. All RCTs which had treatment arms of IAI agents (autologous conditioned serum, botulinum neurotoxin type A, corticosteroids, dextrose prolotherapy (DxTP), hyaluronic acid, mesenchymal stem cells (MSC), ozone, platelet-rich plasma, plasma rich in growth factor, and stromal vascular fraction of adipose tissue) in combination with PT (exercise therapy, physical agent modalities (electrotherapy, shockwave therapy, thermal therapy), and physical activity training) were included in this NMA. A control arm receiving placebo IAI or usual care, without any other IAI or PT, was used as the reference group. The selected RCTs were analyzed through a frequentist method of NMA. The main outcomes included pain, global function (GF), and walking capability (WC). Meta-regression analyses were performed to explore potential moderators of the treatment efficacy. We included 80 RCTs (6934 patients) for analyses. Among the ten identified IAI+PT regimens, DxTP plus PT was the most optimal treatment for pain reduction (standard mean difference (SMD) = -2.54) and global function restoration (SMD = 2.28), whereas MSC plus PT was the most effective for enhancing WC recovery (SMD = 2.54). More severe KOA was associated with greater changes in pain (ß = -2.52) and WC (ß = 2.16) scores. Combined IAI+PT treatments afford more benefits than do their corresponding monotherapies in patients with KOA; however, treatment efficacy is moderated by disease severity.

Osteoporosis increases the risk of rotator cuff tears: a population-based cohort study.

INTRODUCTION: Osteoporosis has been demonstrated to be a risk factor for rotator cuff retears after surgery; however, no studies have directly investigated the association between osteoporosis and the development of rotator cuff tears. To investigate whether osteoporosis is associated with an increased risk of rotator cuff tears. MATERIALS AND METHODS: We conducted a population-based, matched-cohort study with a 7-year follow-uTwo matched cohorts (n = 3511 with osteoporosis and 17,555 without osteoporosis) were recruited from Taiwan's Longitudinal Health Insurance Dataset. Person-year data and incidence rates were evaluated. A multivariable Cox model was used to derive an adjusted hazard ratio (aHR) after controlling for age, sex, and various prespecified comorbidities. Age and sex were added in the model to test for interaction with osteoporosis. RESULTS: Women constituted 88.5% of the cohorts. During follow-up of 17,067 and 100,501 person-years for the osteoporosis and nonosteoporosis cohorts, 166 and 89 rotator cuff tears occurred, respectively. The cumulative incidence of rotator cuff tears was significantly higher in the osteoporosis cohort than in the nonosteoporosis cohort (p < 0.001, log-rank). The Cox model revealed a 1.79-fold increase in rotator cuff tears in the osteoporosis cohort, with an aHR of 1.79 (95% confidence interval, 1.55-2.05). Effect modification of sex and age on rotator cuff tears was not found in patients with osteoporosis. CONCLUSION: This population-based study supports the hypothesis that compared with individuals without osteoporosis, those with osteoporosis have a higher risk of developing rotator cuff tears.

Efficacy and Safety of Multiple Dupilumab Dose Regimens in Patients with Moderate-To-Severe Atopic Dermatitis: A Systematic Review and Network Meta-Analysis of Randomized Controlled Trials.

BACKGROUND: Dupilumab ameliorates the signs and symptoms of atopic dermatitis (AD) and improves the patient's quality of life. Multiple-dose regimens of dupilumab have been applied by clinicians, but the efficacy of some regimens remains unclear. OBJECTIVES: The aim of the study was to systematically evaluate the efficacy and safety of multiple dupilumab dose regimens in patients with moderate-to-severe AD in terms of comprehensive outcomes. METHODS: We searched electronic databases and subjected the selected studies to risk-of-bias assessment and network meta-analysis (NMA). Efficacy and safety outcomes were compared using a random-effects NMA to estimate pooled relative risk ratio (RR) of direct and indirect comparisons among multiple dupilumab dose regimens. The Eczema Area Severity Index, Investigator's Global Assessment, and pruritus numerical rating scale were analyzed to assess the efficacy, while adverse events (AEs) and serious adverse events to represent the safety. RESULTS: Eight randomized controlled trials involving 3,679 patients were identified. Most patients received therapy for 16 weeks. Multiple dupilumab dose regimens, including 300 mg weekly (QW), 300 mg every 2 weeks (Q2W), 200 mg Q2W, 300 mg monthly (QM), 300 mg every 2 months (Q2M), and 100 mg QM were analyzed. All regimens, except 100 mg QM, had significantly better efficacy than placebo. 300 mg QW and 300 mg Q2W appeared to have similar efficacy. Notably, both 300 mg QW and 300 mg Q2W had no significantly better efficacy than 300 mg QM. As for 300 mg Q2M, significantly reduced efficacy was noted in only one efficacy outcome when compared to 300 mg QW and 300 mg Q2W. In terms of safety outcomes, AEs occurring with any of the regimens were comparable with the placebo. No significant inconsistency was noted within the network in all efficacy outcomes. CONCLUSIONS: Our NMA indicated that the administration of the following dupilumab regimens was effective for patients with moderate-to-severe AD: 300 mg QW, 300 mg Q2W, 200 mg Q2W, 300 mg QM, and 300 mg Q2M. Our data can improve the understanding of the relative efficacy and safety of multiple dupilumab dose regimens, which will help in shared decision-making between clinicians and patients.

Simulation-based holistic education in physiotherapy interns to increase empathy toward older adults and individuals with disabilities.

BACKGROUND: The proportion of older adults and individuals with disabilities in the general population increases each year. Thus, clinical clerkships designed for physiotherapy interns should provide more than simply knowledge and skills. For such interns to be able to handle the requirements of their future jobs, clerkships must enable them to develop empathy and positive attitudes toward patients. This study investigated the effect of simulation-based, holistic health-care education on physiotherapy interns' empathy, attitudes, and knowledge.  METHODS: A parallel-group design. Thirty physiotherapy interns from a medical institution were enrolled as participants, with experimental and control groups each comprising 15 participants. Both groups received standard clinical training. However, the experimental group received an additional 3.5 h of simulation-based holistic health-care education. The Jefferson Scale of Empathy, Kogan's Attitudes Toward Old People Scale, the Attitudes Towards the Elderly Scale, the Knowledge About Aging Scale, Knowledge of the Situation of Older People Scale, Perceptions of Working with Older People Scale, and Care Willingness Scale were used in a pretest and posttest. RESULTS: After the intervention period, we observed substantial between-group differences of 6.4 points on the Jefferson Scale of Empathy (p = 0.001), 7.7 points on Kogan's Attitudes Toward Old People Scale (p = 0.002), 3.5 points on the Attitudes Toward the Elderly Scale (p = 0.002), 2.5 points on Knowledge About Aging (p = 0.055), 4.5 points on the Knowledge of the Situation of Older People Scale (p < 0.001), and 2.1 points on Perceptions of Working with Older People Scale (p = 0.046). CONCLUSION: Simulation-based, holistic health-care education can significantly improve the empathy, knowledge, and attitudes of physiotherapy interns.

Exercise therapy for sarcopenia in rheumatoid arthritis: A meta-analysis and meta-regression of randomized controlled trials.

OBJECTIVE: Rheumatoid arthritis and age are associated with high sarcopenia risk. Exercise is an effective treatment for preventing muscle mass loss in older adult populations. It remains unclear whether exercise affects muscle mass in people with rheumatoid arthritis. Thus, this meta-analysis investigated the effect of exercise on muscle mass gain in patients with rheumatoid arthritis. DATA SOURCES: PubMed, EMBASE, the Cochrane Library, the Physiotherapy Evidence Database (PEDro), the China Knowledge Resource Integrated Database, and Google Scholar were systematically searched until June 2021. METHODS: The present study was conducted according to the guidelines recommended by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis. Randomized controlled trials (RCTs) that reported the effects of exercise on muscle mass for rheumatoid arthritis were identified. The included RCTs were subject to meta-analysis and risk of bias assessment. Subgroup and random-effects meta-regression analyses were performed to identify any heterogeneity (I2) of treatment effects across studies. RESULTS: We included nine RCTs with a median PEDro score of 6/10 (range: 4/10-8/10). The weighted mean effect size for muscle mass was 0.77 (95% CI: 0.30-1.24; P = 0.001; I2 = 77%). Meta-regression analyses indicated that the disease duration significantly explained variance of treatment effects across studies (ß = -0.006, R2 = 69.7%, P = 0.005). CONCLUSIONS: Exercise therapy effectively increased muscle mass in patients with rheumatoid arthritis. Treatment effects may be attenuated in those who have had rheumatoid arthritis for a relatively long time.

Effectiveness, Compliance, and Safety of Dextrose Prolotherapy for Knee Osteoarthritis: A Meta-Analysis and Metaregression of Randomized Controlled Trials.

OBJECTIVES: This study assessed the effectiveness, compliance, and safety of dextrose prolotherapy for patients with knee osteoarthritis. DATA SOURCES: PubMed, EMBASE, the Cochrane Library Database, and the Scopus database from their inception to December 31, 2021. METHODS: This study was conducted in accordance with the guidelines recommended by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis. Randomized controlled trials regarding the effectiveness of dextrose prolotherapy in knee osteoarthritis were identified. The included trials were subjected to meta-analysis. Risk of bias was assessed using the Cochrane risk of bias tool. Subgroup and random-effects metaregression analyses were performed to explore any heterogeneity (I2) of treatment effects across studies. RESULTS: A total of 14 trials enrolling 978 patients were included in the meta-analysis. Compared with placebo injection and noninvasive control therapy, dextrose prolotherapy had favorable effects on pain, global function, and quality of life during the overall follow-up. Dextrose prolotherapy yielded greater reductions in pain score over each follow-up duration than did the placebo. Compared with other invasive therapies, dextrose prolotherapy generally achieved comparable effects on pain and functional outcomes for each follow-up duration.Subgroup results indicated that combined intra-articular and extra-articular injection techniques may have stronger effects on pain than a single intra-articular technique. CONCLUSIONS: Dextrose prolotherapy may have dose-dependent and time-dependent effects on pain reduction and function recovery, respectively, in patients with knee osteoarthritis. Due to remarkable heterogeneity and the risk of biases across the included trials, the study results should be cautiously interpreted.

The effectiveness of functional electrical stimulation of the legs in patients with heart failure: A systematic review and meta-analysis of randomized controlled trials.

OBJECTIVE: To investigate the effectiveness of functional electrical stimulation of the legs in patients with heart failure. METHODS: Data were obtained from PubMed, Cochrane Library, and Embase databases until August 12, 2021. We included randomized controlled trials that evaluated the effects of functional electrical stimulation applied to the legs of patients with heart failure, namely changes in cardiopulmonary function, muscle strength, and quality of life. RESULTS: In total, 14 randomized controlled trials (consisting of 518 patients) were included in our article. Pooled estimates demonstrated that functional electrical stimulation significantly improved peak oxygen consumption (peak VO2; standardized mean difference = 0.33, 95% confidence interval = 0.07-0.59, eight randomized controlled trials, n = 321), 6-min walking distance (mean difference = 48.03 m, 95% confidence interval = 28.50-67.57 m, 10 randomized controlled trials, n = 380), and Minnesota Living with Heart Failure Questionnaire quality of life score (mean difference = - 8.23, 95% confidence interval = - 12.64 to - 3.83, nine randomized controlled trials, n = 383). Muscle strength of lower extremities was not significantly improved in the functional electrical stimulation group compared with that in the control group (standardized mean difference = 0.26, 95% confidence interval = - 0.18 to 0.71, five randomized controlled trials, n = 218). Furthermore, the subgroup analysis revealed that functional electrical stimulation significantly improved peak VO2, 6-min walking distance, and Minnesota Living with Heart Failure Questionnaire quality of life score in the heart failure with reduced ejection fraction and heart failure with preserved ejection fraction subgroups. CONCLUSION: Functional electrical stimulation can effectively improve the cardiopulmonary function and quality of life in patients with heart failure. However, functional electrical stimulation did not significantly improve muscle strength in the legs.

Hybrid robot-assisted gait training for motor function in subacute stroke: a single-blind randomized controlled trial.

BACKGROUND: Robot-assisted gait training (RAGT) is a practical treatment that can complement conventional rehabilitation by providing high-intensity repetitive training for patients with stroke. RAGT systems are usually either of the end-effector or exoskeleton types. We developed a novel hybrid RAGT system that leverages the advantages of both types. OBJECTIVE: This single-blind randomized controlled trial evaluated the beneficial effects of the novel RAGT system both immediately after the intervention and at the 3-month follow-up in nonambulatory patients with subacute stroke. METHODS: We recruited 40 patients with subacute stroke who were equally randomized to receive conventional rehabilitation either alone or with the addition of 15 RAGT sessions. We assessed lower-extremity motor function, balance, and gait performance by using the following tools: active range of motion (AROM), manual muscle test (MMT), the Fugl-Meyer Assessment (FMA) lower-extremity subscale (FMA-LE) and total (FMA-total), Postural Assessment Scale for Stroke (PASS), Berg Balance Scale (BBS), Tinetti Performance-Oriented Mobility Assessment (POMA) balance and gait subscores, and the 3-m and 6-m walking speed and Timed Up and Go (TUG) tests. These measurements were performed before and after the intervention and at the 3-month follow-up. RESULTS: Both groups demonstrated significant within-group changes in the AROM, MMT, FMA-LE, FMA-total, PASS, BBS, POMA, TUG, and 3-m and 6-m walking speed tests before and after intervention and at the 3-month follow-up (p < 0.05). The RAGT group significantly outperformed the control group only in the FMA-LE (p = 0.014) and total (p = 0.002) assessments. CONCLUSION: Although the novel hybrid RAGT is effective, strong evidence supporting its clinical effectiveness relative to controls in those with substantial leg dysfunction after stroke remains elusive. Trial registration The study was registered with an International Standard Randomized Controlled Trial Number, ISRCTN, ISRCTN15088682. Registered retrospectively on September 16, 2016, at https://www.isrctn.com/ISRCTN15088682.

Safety of Special Waveform of Transcranial Electrical Stimulation (TES): In Vivo Assessment.

Intermittent theta burst (iTBS) powered by direct current stimulation (DCS) can safely be applied transcranially to induce neuroplasticity in the human and animal brain cortex. tDCS-iTBS is a special waveform that is used by very few studies, and its safety needs to be confirmed. Therefore, we aimed to evaluate the safety of tDCS-iTBS in an animal model after brain stimulations for 1 h and 4 weeks. Thirty-one Sprague Dawley rats were divided into two groups: (1) short-term stimulation for 1 h/session (sham, low, and high) and (2) long-term for 30 min, 3 sessions/week for 4 weeks (sham and high). The anodal stimulation applied over the primary motor cortex ranged from 2.5 to 4.5 mA/cm2. The brain biomarkers and scalp tissues were assessed using ELISA and histological analysis (H&E staining) after stimulations. The caspase-3 activity, cortical myelin basic protein (MBP) expression, and cortical interleukin (IL-6) levels increased slightly in both groups compared to sham. The serum MBP, cortical neuron-specific enolase (NSE), and serum IL-6 slightly changed from sham after stimulations. There was no obvious edema or cell necrosis seen in cortical histology after the intervention. The short- and long-term stimulations did not induce significant adverse effects on brain and scalp tissues upon assessing biomarkers and conducting histological analysis.

Motor Neuroplastic Effects of a Novel Paired Stimulation Technology in an Incomplete Spinal Cord Injury Animal Model.

Paired stimulation of the brain and spinal cord can remodel the central nervous tissue circuitry in an animal model to induce motor neuroplasticity. The effects of simultaneous stimulation vary according to the extent and severity of spinal cord injury. Therefore, our study aimed to determine the significant effects on an incomplete SCI rat brain and spinal cord through 3 min and 20 min stimulations after 4 weeks of intervention. Thirty-three Sprague Dawley rats were classified into six groups: (1) normal, (2) sham, (3) iTBS/tsDCS, (4) iTBS/ts-iTBS, (5) rTMS/tsDCS, and (6) rTMS/ts-iTBS. Paired stimulation of the brain cortex and spinal cord thoracic (T10) level was applied simultaneously for 3−20 min. The motor evoked potential (MEP) and Basso, Beattie, and Bresnahan (BBB) scores were recorded after every week of intervention for four weeks along with wheel training for 20 min. Three-minute stimulation with the iTBS/tsDCS intervention induced a significant (p < 0.050 *) increase in MEP after week 2 and week 4 treatments, while 3 min iTBS/ts-iTBS significantly improved MEP (p < 0.050 *) only after the week 3 intervention. The 20 min rTMS/ts-iTBS intervention showed a significant change only in post_5 min after week 4. The BBB score also changed significantly in all groups except for the 20 min rTMS/tsDCS intervention. iTBS/tsDCS and rTMS/ts-iTBS interventions induce neuroplasticity in an incomplete SCI animal model by significantly changing electrophysiological (MEP) and locomotion (BBB) outcomes.

High-intensity functional exercise in older adults with dementia: A systematic review and meta-analysis.

OBJECTIVE: This study aimed to investigate the efficacy of high-intensity functional exercise among older adults with dementia. METHODS: In this systematic review and meta-analysis of randomized controlled trials, we collected articles published before August 2020 from PubMed, Embase, and the Cochrane Library to evaluate the effect of high-intensity functional exercise on older adults with dementia. Primary outcomes included improvements in balance function and gait performance (speed, cadence, and stride length). The secondary outcomes included lower limb strength, activities of daily living, psychiatric well-being, depression, and cognition. Furthermore, we performed subgroup analysis with two high-intensity functional exercise programs: the Umeå program and Hauer's program. RESULTS: We identified 15 articles describing six trials including older adults with dementia undergoing high-intensity functional exercise or control activity. The meta-analysis indicated that high-intensity functional exercise, both in Hauer's program and in the Umeå program, significantly improved balance function (pooled standardized mean difference 0.57, 95% confidence interval 0.31-0.83). Hauer's program significantly improved gait speed, cadence, stride length, and lower limb strength. Beneficial effects on speed, cadence, and lower limb strength were retained for several months. The Umeå program facilitated activities of daily living and psychiatric well-being, with effects on activities of daily living lasting several months. In the only eligible trial, no effects on cognition were observed. Adverse effects of high-intensity functional exercise were minimal to none. CONCLUSIONS: High-intensity functional exercise is generally safe and is recommended for older individuals with mild or moderate dementia to provide benefits in motor performance and daily functioning.

Clinical efficacy of extracorporeal shockwave therapy for knee osteoarthritis: a systematic review and meta-regression of randomized controlled trials.

OBJECTIVE: This study determined the clinical efficacy of extracorporeal shockwave therapy and the predictors of its efficacy for knee osteoarthritis. DATA SOURCES: Electronic databases and search engines, namely MEDLINE, PubMed, EMBASE, Cochrane Library Database, Physiotherapy Evidence Database (PEDro), China Academic Journals Full-text Database, and Google Scholar, were searched until 5 March 2019, for randomized controlled trials without restrictions on language and publication year. REVIEW METHODS: Eligible trials and extracted data were identified by two independent investigators. The included articles were subjected to a meta-analysis and risk of bias assessment. Outcomes of interest included treatment success rate, pain, and physical function outcomes. A meta-regression analysis was performed to determine the predictors of treatment outcomes following shockwave therapy. RESULTS: We included 50 trials (4844 patients) with a median (range) PEDro score of 6 (5-9). Meta-analyses results revealed an overall significant effect favoring shockwave therapy on the treatment success rate (odds ratio 3.22, 95% confidence interval (CI) 2.21-4.69, P < 0.00001; heterogeneity (I2) = 62%), pain reduction (standardized mean difference (SMD) -2.02, 95% CI -2.38 to -1.67, P < 0.00001; I2 = 95%), and Western Ontario and McMaster Universities Osteoarthritis Index function outcome (SMD -2.71, 95% CI -3.50 to -1.92, P < 0.00001; I2 = 97%). Follow-up duration and energy flux density were independent significant predictors of shockwave efficacy. CONCLUSION: Shockwave therapy is beneficial for knee osteoarthritis. Shockwave dosage, particularly the energy level and intervention duration, may have different contributions to treatment efficacy.

Repetitive transcranial magnetic stimulation of lower limb motor function in patients with stroke: a systematic review and meta-analysis of randomized controlled trials.

OBJECTIVE: The aim of this study was to evaluate the effects of repetitive transcranial magnetic stimulation (rTMS) on the post-stroke recovery of lower limb motor function. DATA SOURCES: We searched the databases of PubMed, Cochrane Library, and Embase. The randomized controlled trials were published by 25 January 2019. REVIEW METHODS: We included randomized controlled trials that evaluated the effects of rTMS on lower limb motor recovery in patients with stroke. Two reviewers independently screened the searched records, extracted data, and assessed the risk of bias. The treatment effect sizes were pooled in a meta-analysis by using the RevMan 5.3 software. The internal validity was assessed using topics suggested by the Physiotherapy Evidence Database (PEDro). RESULTS: Eight studies with 169 participants were included in the meta-analysis. Pooled estimates demonstrated that rTMS significantly improved the body function of the lower limbs (standardized mean difference (SMD) = 0.66; P < 0.01), lower limb activity (SMD = 0.66; P < 0.01), and motor-evoked potential (SMD = 1.13; P < 0.01). The subgroup analyses results also revealed that rTMS improved walking speed (SMD = 1.13) and lower limb scores on the Fugl-Meyer Assessment scale (SMD = 0.63). We found no significant differences between the groups in different mean post-stroke time or stimulation mode over lower limb motor recovery. Only one study reported mild adverse effects. CONCLUSION: rTMS may have short-term therapeutic effects on the lower limbs of patients with stroke. Furthermore, the application of rTMS is safe. However, this evidence is limited by a potential risk of bias.

Effectiveness of electrical stimulation therapy in improving arm function after stroke: a systematic review and a meta-analysis of randomised controlled trials.

OBJECTIVE: The aim of this study is to investigate the effectiveness of electrical stimulation in arm function recovery after stroke. METHODS: Data were obtained from the PubMed, Cochrane Library, Embase, and Scopus databases from their inception until 12 January 2019. Only randomized controlled trials (RCTs) reporting the effects of electrical stimulation on the recovery of arm function after stroke were selected. RESULTS: Forty-eight RCTs with a total of 1712 patients were included in the analysis. The body function assessment, Upper-Extremity Fugl-Meyer Assessment, indicated more favorable outcomes in the electrical stimulation group than in the placebo group immediately after treatment (23 RCTs (n = 794): standard mean difference (SMD) = 0.67, 95% confidence interval (CI) = 0.51-0.84) and at follow-up (12 RCTs (n = 391): SMD = 0.66, 95% CI = 0.35-0.97). The activity assessment, Action Research Arm Test, revealed superior outcomes in the electrical stimulation group than those in the placebo group immediately after treatment (10 RCTs (n = 411): SMD = 0.70, 95% CI = 0.39-1.02) and at follow-up (8 RCTs (n = 289): SMD = 0.93, 95% CI = 0.34-1.52). Other activity assessments, including Wolf Motor Function Test, Box and Block Test, and Motor Activity Log, also revealed superior outcomes in the electrical stimulation group than those in the placebo group. Comparisons between three types of electrical stimulation (sensory, cyclic, and electromyography-triggered electrical stimulation) groups revealed no significant differences in the body function and activity. CONCLUSION: Electrical stimulation therapy can effectively improve the arm function in stroke patients.

Preoperative range of motion and applications of continuous passive motion predict outcomes after knee arthroplasty in patients with arthritis.

PURPOSE: This study evaluated the clinical efficacy of continuous passive motion (CPM) following knee arthroplasty and determined the predictors of effect sizes of range of motion (ROM) and functional outcomes in patients with knee arthritis. METHODS: A comprehensive electronic database search was performed for randomized controlled trials (RCTs), without publication year or language restrictions. The included RCTs were analyzed through meta-analysis and risk of bias assessment. Study methodological quality (MQ) was assessed using the Physiotherapy Evidence Database (PEDro) scale. Inverse-variance weighted univariate and multivariate metaregression analyses were performed to determine the predictors of treatment outcomes. RESULTS: A total of 77 RCTs with PEDro scores ranging from 6/10 to 8/10 were included. Meta-analyses revealed an overall significant favorable effect of CPM on treatment success rates [odds ratio: 3.64, 95% confidence interval (CI) 2.21-6.00]. Significant immediate [postoperative day 14; standard mean difference (SMD): 1.06; 95% CI 0.61-1.51] and short-term (3-month follow-up; SMD: 0.80; 95% CI 0.45-1.15) effects on knee ROM and a long-term effect on function (12-month follow-up; SMD: 1.08; 95% CI 0.28-1.89) were observed. The preoperative ROM, postoperative day of CPM initiation, daily ROM increment, and total application days were significant independent predictors of CPM efficacy. CONCLUSION: Early CPM initiation with rapid progress over a long duration of CPM application predicts higher treatment effect on knee ROM and function. The results were based on a moderate level of evidence, with good MQ and potential blinding biases in the included RCTs. An aggressive protocol of CPM has clinically relevant beneficial short-term and long-term effects on postoperative outcomes. LEVEL OF EVIDENCE: II.

Efficacy of extracorporeal shock wave therapy for knee tendinopathies and other soft tissue disorders: a meta-analysis of randomized controlled trials.

BACKGROUND: Extracorporeal shock-wave therapy (ESWT), which can be divided into radial shock-wave therapy (RaSWT) and focused shock-wave therapy (FoSWT), has been widely used in clinical practice for managing orthopedic conditions. The aim of this study was to determine the clinical efficacy of ESWT for knee soft tissue disorders (KSTDs) and compare the efficacy of different shock-wave types, energy levels, and intervention durations. METHODS: We performed a comprehensive search of online databases and search engines without restrictions on the publication year or language. We selected randomized controlled trials (RCTs) reporting the efficacy of ESWT for KSTDs and included them in a meta-analysis and risk of bias assessment. The pooled effect sizes of ESWT were estimated by computing odds ratios (ORs) with 95% confidence intervals (CIs) for the treatment success rate (TSR) and standardized mean differences (SMDs) with 95% CIs for pain reduction (i.e., the difference in pain relief, which was the change in pain from baseline to the end of RCTs between treatment and control groups) and for restoration of knee range of motion (ROM). RESULTS: We included 19 RCTs, all of which were of high or medium methodological quality and had a Physiotherapy Evidence Database score of ≥5/10. In general, ESWT had overall significant effects on the TSR (OR: 3.36, 95% CI: 1.84-6.12, P < 0.0001), pain reduction (SMD: - 1.49, 95% CI: - 2.11 to - 0.87, P < 0.00001), and ROM restoration (SMD: 1.76, 95% CI: 1.43-2.09, P < 0.00001). Subgroup analyses revealed that FoSWT and RaSWT applied for a long period (≥1 month) had significant effects on pain reduction, with the corresponding SMDs being - 3.13 (95% CI: - 5.70 to - 0.56; P = 0.02) and - 1.80 (95% CI: - 2.52 to - 1.08; P < 0.00001), respectively. Low-energy FoSWT may have greater efficacy for the TSR than high-energy FoSWT, whereas the inverse result was observed for RaSWT. CONCLUSIONS: The ESWT exerts an overall effect on the TSR, pain reduction, and ROM restoration in patients with KSTDs. Shock-wave types and application levels have different contributions to treatment efficacy for KSTDs, which must be investigated further for optimizing these treatments in clinical practice.
