BACKGROUND: Multiple sclerosis (MS) is an immune-mediated, neurodegenerative disease of the central nervous system that manifests in symptoms that compromise health-related quality of life (HRQOL). HRQOL focuses on a person's overall, subjective evaluation of health status primarily in the physical and mental domains. Exercise training is a form of rehabilitation for managing MS-related outcomes that might influence HRQOL. Reviews on exercise training are available, but we are unaware of a recent comprehensive review and meta-analysis of exercise effects for improving physical and mental domains of HRQOL. This analysis provides an updated review and meta-analysis of randomized controlled trials (RCTs) examining interventions consisting of aerobic, resistance and combined exercise training for improving HRQOL in persons with MS. This systematic review 1) assessed the overall strength of evidence for exercise interventions on HRQOL, 2) evaluated the relative effect of exercise interventions on physical and mental domains of HRQOL, and 3) determined moderators of exercise intervention effects on HRQOL.
METHODS: Seven databases were searched for RCTs evaluating physical and/or mental domains of HRQOL with adults diagnosed with MS and undergoing an intervention of aerobic, resistance or combined exercise training compared with a non-exercise comparator. Data extraction included participant and intervention characteristics, and pre- and post-intervention HRQOL outcome data. Effect sizes (ESs) were calculated as standardized mean differences (SMDs) and a multilevel random-effects model was used to generate an aggregated SMD that compared exercise with non-exercise control conditions.
RESULTS: Twelve RCTs met the inclusion criteria and yielded 23 ESs to be analyzed. Participants (N = 593; 308 intervention vs. 285 control conditions) had a mean (±standard deviation) age of 42.4 (6.5) years and 80% (18.3%) were female. Results generated a medium effect of exercise for improving overall HRQOL (ES=0.64, p = 0.0001) with high heterogeneity (Q11=58.8, I2=86.7%). Exercise training yielded a large effect on the physical domain (k = 12, ES=0.82, p<0.0009) and a medium effect on the mental domain (k = 11, ES=0.41, p<0.0001). Moderator analyses identified exercise modality, supervision level, intervention delivery and length, HRQOL tool, and number of participants with relapsing-remitting MS as significant influences of ES for HRQOL.
CONCLUSIONS: Exercise training is clinically effective for improving overall HRQOL in MS and produces greater improvements in the physical domain of HRQOL than the mental domain. The moderator analysis suggests that supervised, aerobic, and group-delivered exercise training of ≥3 months yields the most influence on HRQOL. Such results may have major implications for MS treatment and care.
OBJECTIVE: To determine the effect of aerobic exercise on brain-derived neurotrophic factor (BDNF) levels in people with neurological disorders.
DATA SOURCES: Six electronic databases (CINAHL, PubMed, Cochrane, PsycINFO, SportDiscus, and Web of Science) were searched until the end of December 2016.
STUDY SELECTION: Experimental or observational studies of people with neurological disorders who undertook an exercise intervention with BDNF as an outcome measure. The search strategy yielded 984 articles.
DATA EXTRACTION: Study data were independently extracted from each article. Methodological quality of studies was assessed using the Physiotherapy Evidence Database (PEDro) scale. A meta-analysis was planned based on the assessment of predetermined criteria.
DATA SYNTHESIS: Eleven articles were included. Studies employed either a program of aerobic exercise, a single bout of aerobic exercise, or both. A meta-analysis of studies comparing a program of aerobic exercise against usual care/nil therapy showed a large effect (SMD: 0.84, 95% CI 0.47-1.20, p < 0.001) in favour of aerobic exercise to increase levels of BDNF. Findings for a single bout of aerobic exercise were mixed. Quality of studies was low (PEDro average score 4.3/10).
CONCLUSIONS: A program of aerobic exercise may contribute to increased levels of BDNF in neurological populations.
BACKGROUND: Telerehabilitation, an emerging method, extends rehabilitative care beyond the hospital, and facilitates multifaceted, often psychotherapeutic approaches to modern management of patients using telecommunication technology at home or in the community. Although a wide range of telerehabilitation interventions are trialed in persons with multiple sclerosis (pwMS), evidence for their effectiveness is unclear.
OBJECTIVES: To investigate the effectiveness and safety of telerehabilitation intervention in pwMS for improved patient outcomes. Specifically, this review addresses the following questions: does telerehabilitation achieve better outcomes compared with traditional face-to-face intervention; and what types of telerehabilitation interventions are effective, in which setting and influence which specific outcomes (impairment, activity limitation and participation)?
SEARCH METHODS: We performed a literature search using the Cochrane Multiple Sclerosis and Rare Diseases of the Central Nervous System Review Group Specialised Register( 9 July, 2014.) We handsearched the relevant journals and screened the reference lists of identified studies, and contacted authors for additional data.
SELECTION CRITERIA: Randomised controlled trials (RCTs) and controlled clinical trials (CCTs) that reported telerehabilitation intervention/s in pwMS and compared them with some form of control intervention (such as lower level or different types of intervention, minimal intervention, waiting-list controls or no treatment (or usual care); interventions given in different settings) in adults with MS.
DATA COLLECTION AND ANALYSIS: Two review authors independently selected studies and extracted data. Three review authors assessed the methodological quality of studies using the GRADEpro software (GRADEpro 2008) for best-evidence synthesis. A meta-analysis was not possible due to marked methodological, clinical and statistical heterogeneity between included trials and between measurement tools used. Hence, we performed a best-evidence synthesis using a qualitative analysis.
MAIN RESULTS: Nine RCTs, one with two reports, (N = 531 participants, 469 included in analyses) investigated a variety of telerehabilitation interventions in adults with MS. The mean age of participants varied from 41 to 52 years (mean 46.5 years) and mean years since diagnosis from 7.7 to 19.0 years (mean 12.3 years). The majority of the participants were women (proportion ranging from 56% to 87%, mean 74%) and with a relapsing-remitting course of MS. These interventions were complex, with more than one rehabilitation component and included physical activity, educational, behavioural and symptom management programmes.All studies scored 'low' on the methodological quality assessment. Overall, the review found 'low-level' evidence for telerehabilitation interventions in reducing short-term disability and symptoms such as fatigue. There was also 'low-level' evidence supporting telerehabilitation in the longer term for improved functional activities, impairments (such as fatigue, pain, insomnia); and participation measured by quality of life and psychological outcomes. There were limited data on process evaluation (participants'/therapists' satisfaction) and no data available for cost effectiveness. There were no adverse events reported as a result of telerehabilitation interventions.
AUTHORS' CONCLUSIONS: There is currently limited evidence on the efficacy of telerehabilitation in improving functional activities, fatigue and quality of life in adults with MS. A range of telerehabilitation interventions might be an alternative method of delivering services in MS populations. There is insufficient evidence to support on what types of telerehabilitation interventions are effective, and in which setting. More robust trials are needed to build evidence for the clinical and cost effectiveness of these interventions.
BACKGROUND: Cognitive impairment is a well-established sequela of people suffering from neurological pathologies.
OBJECTIVE: To examine the effects of exercise intervention programs on cognitive performance in participants suffering from stroke, multiple sclerosis and Parkinson's disease.
METHODS: Four online databases (CINAHL, Cochrane Library, MEDLINE, PEDro) were comprehensively searched from their inception through December 2014. The search query was phrased as follows: In people suffering from MS, stroke or Parkinson's disease, do exercise intervention programs improve cognitive performance?
RESULTS: Twelve controlled clinical trials met our inclusion criteria. Studies were classified according to three clinical subgroups: Parkinson's disease (n = 3), stroke (n = 1) and multiple sclerosis (n = 8). Eight studies employed an aerobic intervention program; one used an active exercise program based on virtual reality systems, three reports examined the effect of yoga and one compared the intervention program with sport climbing. Significant improvements in cognition were found in nine out of the twelve studies. Nevertheless, the total effect size was non-significant (0.18 (95% CI, - 4.1, 3.8)) for changes in executive functions.
CONCLUSION: Due to lack of commonality between measures of cognition, training sequences and intervention period, it remains unclear as to whether exercise training can be effective in improving the cognitive functions of neurological patients.
Background and purpose: The purpose of this study was to perform a systematic review of the literature on the effects of exercise on depressive symptoms in patients with multiple sclerosis (MS), as well as to apply meta‐analytical procedures to the results. METHODS: A systematic search covering eight databases was conducted. The included studies were randomized controlled trials applied to people with definite MS who completed a structured exercise intervention which were compared to any comparator, including other forms of exercise. The outcomes included a primary measure of depression/depressive symptoms or an instrument with a clearly defined depression subscale. RESULTS: Fifteen randomized controlled trial studies were identified including a total of 331 exercising subjects and 260 controls. The average Physiotherapy Evidence Database (PEDro) score was 5.6 ± 1.3 points. Only one study applied depressive symptoms as the primary outcome. Four studies showed positive effects of exercise on depressive symptoms. An in‐depth analysis of the studies revealed that the baseline level of depressive symptoms, patient disability level, choice of depression instrument and exercise intensity may influence the results. The meta‐analysis included 12 studies reflecting a total of 476 subjects. The standardized mean difference across studies was <i>g</i> = −0.37, 95% confidence interval (−0.56; −0.17), and the null hypothesis of homogeneity within the sample could not be rejected (Q = 12.05, df = 11, <i>P</i> = 0.36). DISCUSSION: Exercise may be a potential treatment to prevent or reduce depressive symptoms in individuals with MS, but existing studies do not allow solid conclusions. Future well‐designed studies evaluating the effects of exercise on depressive symptoms and major depression disorder in MS are highly warranted.

BACKGROUND: Telerehabilitation, a service delivery model using telecommunications technology to provide therapy at a distance, is used in persons with multiple sclerosis (pwMS), but evidence for their effectiveness is yet to be determined.
OBJECTIVE: To investigate the effectiveness and safety of telerehabilitation intervention pwMS.
METHOD: A comprehensive literature search was conducted using medical and health science electronic databases. Three reviewers selected potential studies and independently assessed the methodological quality. A meta-analysis was not possible due to heterogeneity amongst included trials, and a qualitative analysis was performed for best evidence synthesis.
RESULTS: Ten RCTs and 2 observational studies (n=564 participants) investigated a wide variety of telerehabilitation intervention in pwMS, which included: physical activity; educational, behavioural and symptom management programmes. All studies scored "low to moderate" on the methodological quality assessment implying high risk of bias. Overall, the review found low level evidence for the effectiveness of telerehabilitation on reducing short-term disability and reducing and/or improving symptoms, such as fatigue. There was low level evidence suggesting some benefit of telerehabilitation in improving functional activities; improving symptoms in the longer-term; and psychological outcomes and quality of life. There is limited data on safety, process evaluation and no data on cost-effectiveness of telerehabilitation.
CONCLUSIONS: A wide range of telerehabilitation is used in pwMS, however, the quality of evidence on these interventions was low. More robust trials are needed to build evidence about these interventions.
Objectives To review and quantify the effect of exercise on depression in adults with neurologic disorders. Data Sources CINAHL, Cochrane Register of Controlled Clinical Trials, EMBASE, ERIC, MEDLINE, PsycINFO, PubMed, and SPORTDiscus were searched, with the last search performed in May 2014. Study Selection Included were randomized controlled trials conducted in adults with a diagnosed neurologic disorder that compared an exercise intervention group with a control group and used depression as an outcome measure. Data Extraction Depression data were extracted independently by 2 authors. Methodological quality was assessed independently by 2 authors. Data Synthesis Forty-three full-length articles were reviewed, and 26 trials met our inclusion criteria. These trials represented 1324 participants with 7 different neurologic disorders: Alzheimer disease (n=4 trials), migraine (n=1), multiple sclerosis (n=13), Parkinson disease (n=2), spinal cord injury (n=1), stroke (n=2), and traumatic brain injury (n=3). Data measuring depression were extracted and effect sizes were computed for 23 trials. Results from a meta-analysis yielded an overall effect size of .28 (SE=.07; 95% confidence interval, .15–.41; P =.00) favoring a reduction in depression outcomes after an exercise intervention compared with the control condition. Of note, interventions that met physical activity guidelines yielded an overall effect of .38 compared with .19 for studies that did not meet physical activity guidelines. Conclusions This review provides evidence that exercise, particularly when meeting physical activity guidelines, can improve depressive symptoms in adults with neurologic disorders.

CONCLUSIONS:
Exercise training is clinically effective for improving overall HRQOL in MS and produces greater improvements in the physical domain of HRQOL than the mental domain. The moderator analysis suggests that supervised, aerobic, and group-delivered exercise training of ≥3 months yields the most influence on HRQOL. Such results may have major implications for MS treatment and care.
