The Mini-BESTest is a reliable and valid tool for evaluating balance in people with chronic stroke.

People with various levels of cognitive impairment can benefit from supervised multi-modal exercise for about 60minutes a day, 2 to 3days a week to improve physical function. [Lam FMH , Huang MZ, Liao LR, Chung RCK, Kwok TCY, Pang MYC (2018) Physical exercise improves strength, balance, mobility, and endurance in people with cognitive impairment and dementia: a systematic review. Journal of Physiotherapy 64: 4-15].

Whole body vibration is beneficial for enhancing leg muscle strength among older adults. However, the review suggests that whole body vibration has no overall treatment effect on bone mineral density in older women. No randomized trial has examined the effects of whole body vibration on bone mineral density in older men.

Background: Stroke patients often suffer from poor cardiovascular health and deficits in physical, psychosocial and cognitive functioning. Aerobic exercise training may be a viable treatment approach to address these health issues. The objective of this systematic review was to determine the effects of aerobic exercise on various indicators of health, functioning and quality of life in stroke patients. It was hypothesized that the systematic review would reveal compelling support for the effectiveness of aerobic exercise in stroke patients, such that detailed evidence-based exercise prescription recommendations could be derived. Methods: Major electronic databases were searched systematically to identify randomized controlled studies that examined the effects of aerobic exercise in stroke patients (last search performed in January 2012). The methodological quality of each study was evaluated using the PEDro scale (9–10 = excellent; 6–8 = good; 4–5 = fair; <4 = poor). Based on the methodological quality and sample size used, the level of evidence was determined for each study (level 1: PEDro ≥6 and sample size >50; level 2: PEDro ≤5 or sample size ≤50). Meta-analysis was performed on a given outcome when appropriate. Results: Twenty-five trials fulfilled the selection criteria, of which 8 were level 1 studies. Treadmill and cycle ergometer were the two most popular modalities used to provide aerobic training. The most commonly adopted exercise session duration and frequency was 21–40 min and 3–5 days per week, respectively. The duration of the training programme varied, ranging from 3 weeks to 6 months. Over 60% of the trials used a high training intensity [60–80% heart rate reserve (HRR)]. Meta-analysis showed a significant effect on peak oxygen consumption (p < 0.001), peak workload (p < 0.001), maximal gait speed (p = 0.003) and walking endurance (p < 0.001) in favour of aerobic exercise. Meta-analysis revealed no significant effect on self-selected gait speed, Berg balance score and Functional Independence Measure score. The efficacy of aerobic exercise in improving other health outcomes in physical, psychosocial and cognitive domains as well as quality of life was inconclusive. The health risk associated with engaging in such exercise is small. Conclusions: There is strong evidence that aerobic exercise (40–50% HRR progressing to 60–80%) conducted 20–40 min and 3–5 days per week is beneficial for enhancing aerobic fitness, walking speed and walking endurance in people who have had mild to moderate stroke and are deemed to have low cardiovascular risk with exercise after proper screening assessments (grade A recommendation). The effects of aerobic exercise on other health outcomes require further study.

This systematic review aimed to examine the effect of WBV on balance, mobility and falls among older adults. The databases used included MEDLINE, the Excerpta Medica database, the Cumulative Index to Nursing and Allied Health Literature, the Cochrane Library Databases of Systematic Reviews, Physiotherapy Evidence Database (PEDro), PubMed, and Science Citation Index (last search in October 2011). Randomized controlled trials that investigated the effect of WBV on balance, mobility or falls in older adults were included in this review. The PEDro score was used to examine the methodological quality of the selected studies. The effect of WBV on balance, mobility and fall-related outcomes were extracted. The data extraction and rating were performed by a researcher and the results were confirmed by the principal investigator. Meta-analysis was done if 3 or more studies measured the same outcome of interest. Among 920 articles screened, fifteen articles (thirteen trials) satisfied the criteria and were included in this review. Methodological quality was good for six of the studies (PEDro score=6-7). Meta-analysis revealed that WBV has a significant treatment effect in Tinetti Total Score (p<0.001), Tinetti Body Balance Score (p=0.010) and Timed-Up-and-Go test (p=0.004). No significant improvement was noted in Tinetti Gait Score after WBV training (p=0.120). The effect of WBV on other balance/mobility outcomes and fall rate remains inconclusive. To conclude, WBV may be effective in improving relatively basic balance ability and mobility among older adults, particularly frailer ones. More good-quality WBV trials are required.
