Meta-Analysis Review
OBJECTIVE
To examine the effects of stepping interventions on fall risk factors and fall incidence in older people.
DATA SOURCE
Electronic databases (PubMed, EMBASE, CINAHL, Cochrane, CENTRAL) and reference lists of included articles from inception to March 2015.
STUDY SELECTION
Randomised (RCT) or clinical controlled trials (CCT) of volitional and reactive stepping interventions that included older (minimum age 60) people providing data on falls or fall risk factors.
RESULTS
Meta-analyses of seven RCTs (n=660) showed that the stepping interventions significantly reduced the rate of falls (rate ratio=0.48, 95% CI 0.36 to 0.65, p<0.0001, I=0%) and the proportion of fallers (risk ratio=0.51, 95% CI 0.38 to 0.68, p<0.0001, I=0%). Subgroup analyses stratified by reactive and volitional stepping interventions revealed a similar efficacy for rate of falls and proportion of fallers. A meta-analysis of two RCTs (n=62) showed that stepping interventions significantly reduced laboratory-induced falls, and meta-analysis findings of up to five RCTs and CCTs (n=36-416) revealed that stepping interventions significantly improved simple and choice stepping reaction time, single leg stance, timed up and go performance (p<0.05), but not measures of strength.
CONCLUSIONS
The findings indicate that both reactive and volitional stepping interventions reduce falls among older adults by approximately 50%. This clinically significant reduction may be due to improvements in reaction time, gait, balance and balance recovery but not in strength. Further high-quality studies aimed at maximising the effectiveness and feasibility of stepping interventions are required.

Meta-Analysis
BACKGROUND
Peripheral neuropathy is a major and chronic complication of diabetes mellitus affecting more than 50% patients suffering from diabetes. There is the involvement of both large and small diameter nerve fibres leading to altered somatosensory and motor sensations, thereby causing impaired balance and postural instability.
OBJECTIVE
The aim of this study is to assess the effects of exercises on posture and balance in patients suffering from diabetes mellitus.
METHODS
Mean changes in Timed Up and Go test (TUGT), Berg Balance Scale and Postural Sway with eyes open and eyes closed on Balance System were primary outcome measures. RevMan 5.3 software was used for the meta-analyses. Eighteen randomized controlled trials met the selection criteria and were included in the study. All the studies ranked high on the PEDro Rating scale. The risk of bias was assessed by the Cochrane collaboration tool of risk of bias. Included studies had a low risk of bias. Sixteen RCT's were included for the meta-analysis.
RESULTS
Results of meta-analysis showed that there was a statistically significant improvement in TUGT with p≤ 0.05 and substantial heterogeneity (I2 = 84%, p < 0.00001) in the experimental group as compared to control group. There was a statistically significant difference in Berg Balance Scale scores and heterogeneity of I2 = 62%, p < 0.00001 and significant changes in postural stability (eyes open heterogeneity of I2 = 100%, p =0.01 and eyes closed, heteogeneity I2 = 0%, p =0.01). Sensitivity analysis causes a change in heterogeneity.
CONCLUSION
It can be concluded that various exercises like balance training, core stability, Tai-Chi, proprioceptive training, etc. have a significant effect on improving balance and posture in diabetic neuropathy.

Meta-Analysis Review
Comparison between the effects of exergame intervention and traditional physical training on improving balance and fall prevention in healthy older adults: a systematic review and meta-analysis.
OBJECTIVE
Physical training (PT, e.g., Tai Chi and strength training) has been demonstrated to improve balance control and prevent falls. Recently, exergame intervention (EI) has emerged to prevent falls by enhancing both physical and cognitive functions in older adults. Therefore, we aim to quantitatively assess and compare the effects of PT and EI on the performance of balance control and fall prevention in healthy older adults via meta-analysis.
METHODS
A search strategy based on the PICOS principle was used to find the publication in the databases of PubMed, EMBASE, Web of Science, Cochrane Library, and MEDLINE. The quality and risk of bias in the studies were independently assessed by two researchers.
RESULTS
Twenty studies consisting of 845 participants were included. Results suggested that as compared to PT, EI induced greater improvement in postural control (sway path length, SMD = - 0.66, 95% CI - 0.91 to - 0.41, P < 0.001, I = 0%; sway speed, SMD = - 0.49, 95% CI - 0.71 to - 0.27, P < 0.001, I = 42%) and dynamic balance (SMD = - 0.19, 95% CI - 0.35 to - 0.03, P = 0.02, I = 0%) in healthy older adults. The EI with 90-119 min/week for more than 8-week significantly reduced falls. Subgroup analyses revealed that exergames, which were designed by the two principles of repeatedly performing diversified tasks and gradually increase the difficulty of the task, induced significant effects in improving balance control and falls prevention respectively (P = 0.03, P = 0.009). In addition, intervention that combines EI and PT induced significant improvement in postural control (P = 0.003).
CONCLUSION
The exergame intervention, especially the combination of EI and PT, is a promising strategy to improve balance control and reduce falls in healthy older adults. Future studies with rigorous design, larger sample size, and follow-up assessments are needed to further assess the effectiveness of diverse exergame interventions in fall prevention and to quantify the "dose-effect" relationship, as well as the carry-over effect of such intervention, which will ultimately help optimize the rehabilitative strategies to improve balance control and prevent falls.

Review
Injury risk factors, screening tests and preventative strategies: a systematic review of the evidence that underpins the perceptions and practices of 44 football (soccer) teams from various premier leagues.
PURPOSE
To systematically review the scientific level of evidence for the 'Top 3' risk factors, screening tests and preventative exercises identified by a previously published survey of 44 premier league football (soccer) teams. Also, to provide an overall scientific level of evidence and graded recommendation based on the current research literature.
METHODS
A systematic literature search (Pubmed [MEDLINE], SportDiscus, PEDRO and Cochrane databases). The quality of the articles was assessed and a level of evidence (1++ to 4) was assigned. Level 1++ corresponded to the highest level of evidence available and 4, the lowest. A graded recommendation (A: strong, B: moderate, C: weak, D: insufficient evidence to assign a specific recommendation) for use in the practical setting was given.
RESULTS
Fourteen studies were analysed. The overall level of evidence for the risk factors previous injury, fatigue and muscle imbalance were 2++, 4 and 'inconclusive', respectively. The graded recommendation for functional movement screen, psychological questionnaire and isokinetic muscle testing were all 'D'. Hamstring eccentric had a weak graded 'C' recommendation, and eccentric exercise for other body parts was 'D'. Balance/proprioception exercise to reduce ankle and knee sprain injury was assigned a graded recommendation 'D'.
CONCLUSIONS
The majority of perceptions and practices of premier league teams have a low level of evidence and low graded recommendation. This does not imply that these perceptions and practices are not important or not valid, as it may simply be that they are yet to be sufficiently validated or refuted by research.

Review
BACKGROUND
Shin splint is one of the most common sports injuries after strenuous exercise. Kinesiology taping (KT) is a popular noninvasive remedy used in sports-related disorders, with the potential effects of relieving pain, facilitating proprioception, modulating muscle activation and correcting abnormal movement patterns. However, the exact efficacy of KT on shin splints is still unknown, and previous findings are inconsistent. Hence, this study aimed to conduct a systematic review to evaluate the current status of relevant evidence on its efficacy.
METHODS
The review was performed according to the PRISMA guidelines, and a systematic search of the literature was conducted in December 2020. Electronic databases, Embase, Scopus, Medline, Web of Science, PubMed and Biomed Central were searched for the identification of pertinent studies with pre-defined key terms on shin splints and KT.
RESULTS
Four studies with a total sample size of 141 participants were included and analyzed. Two studies had within-subject designs, whereas the other two were randomized clinical trials. Although the positive results of KT were reported by the studies, methodological quality varied from poor to moderate according to the Physiotherapy Evidence Database Scale or Non-Randomized Studies-of Interventions.
CONCLUSION
In conclusion, this review revealed that the efficacy of KT on shin splints remains not clear. Evidence that supports its effectiveness in individuals with shin splints is currently limited. Further studies with good methodological quality and study design are warranted.

Meta-Analysis Review
BACKGROUND
In recent years, sports games based on virtual reality (VR) have been widely used in the prevention and treatment of diseases related to the elderly. However, there seems to be no consensus on the improvement and comparison of physical function, balance and falls in elderly people with balance impairment.
OBJECTIVE
This study aims to explore the effects of VR intervention on physical function, balance and falls in elderly people with balance impairment.
METHODS
Systematic literature searches of the PubMed, Web of Science, Elsevier, Cochrane, CNKI, and Wanfang databases were performed for VR games-related randomized controlled trials or comparison studies among elderly participants with impaired balance, published in English or Chinese until March 20, 2022. The Cochrane collaboration risk of bias tool was used to evaluate the methodological quality of the studies. A meta-analysis was performed to calculate the standardized mean deviation or mean difference of the sample and its 95% confidence interval (CI) in VR games.
RESULTS
The systematic review included 23 studies. The results showed that VR intervention had significant effects on hand grip strength (MD:1.30, P = 0.040), knee extension strength (MD:-6.27, P<0.001), five times sit-to-stand test scores (MD:1.13, P = 0.030), timed up-and-go test scores (MD:-1.01, P = 0.001), berg balance scale scores (MD:2.37, P<0.001), and falls efficacy scale scores (SMD:-0.28, P = 0.020). Subgroup analysis results showed that VR intervention was more effective on improving TUG and BBS scores than the conventional exercise group (MD=-0.54, P = 0.004; MD=3.24, P<0.001) and the non-intervention group (MD=-0.98, P = 0.001; MD=3.30, P < 0.001). The balance training-based VR had a significant effect on improving TUG (MD=-1.03, P = 0.004) and BBS (MD=2.93, P<0.001), and 20-45 min intervention, ≥3 times/wk, 5-8 wk cycles were significant in improving TUG (MD=-0.89, P<0.001; MD=-0.75, P = 0.0003; MD=-1.54, P<0.0001). VR intervention significantly improved TUG (MD=-2.27, P<0.0001) and BBS (MD=3.41, P<0.0001) in older adults in the hospital or nursing home compared with those residing in communities.
CONCLUSION
VR interventions can help the elderly with impaired balance to overcome traditional sports obstacles and improve physical function, balance and minimize falls. Balance training-based VR intervention is more effective in balance recovery and fall prevention compared with game program. An intervention plan comprising 20-45 min, 5-8 wk cycles, and ≥3 times/wk frequency has significantly higher effects for high-risk elderly populations living in hospitals or nursing homes.

Meta-Analysis
BACKGROUND
The anterior cruciate ligament (ACL) plays a major role in knee proprioception and is thus responsible for maintaining knee joint stability and functionality. The available evidence suggests that ACL reconstruction diminishes somatosensory feedback and proprioceptive functioning, which are vital for adequate joint positioning and movement control.
OBJECTIVE
The aim of this systematic review and meta-analysis was to investigate the effect of an ACL rupture on knee proprioception after arthroscopic ACL repair surgery or conservative treatment.
METHODS
A systematic review with meta-analysis was conducted according to the Preferred Reporting Guidelines for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The literature search was performed in the following databases from inception to 10th October 2020: PubMed, Web of Science, SPORTDiscus, Cochrane Library and Scopus. Randomized and non-randomized studies that evaluated proprioception using the joint position sense (JPS) and threshold to detection of passive motion (TTDPM) techniques at 15°-30° knee flexion with an external healthy control group in a time period between 6 and 24 months post injury or operation were included in the analysis.
RESULTS
In total, 4857 studies were identified, from which 11 were included in the final quantitative analysis. The results demonstrated that proprioception after arthroscopic ACL repair surgery was significantly lower than in the healthy control group (JPS: standardized mean difference [SMD] 0.57, 95% confidence interval [CI] 0.27-0.87, p < 0.01, n = 6 studies; TTDPM: SMD 0.77, 95% CI 0.20-1.34, p < 0.01, n = 4 studies). There were no significant differences in proprioception between the conservative treatment group and the healthy control group (JPS: SMD 0.57, 95% CI - 0.69 to 1.84, p = 0.37, n = 4 studies; TTDPM: SMD 0.82, 95% CI - 0.02 to 1.65, p = 0.05, n = 2 studies), although measures for TTDPM were close to statistical significance.
CONCLUSION
The findings of the present systematic review and meta-analysis revealed that knee proprioception is persistently compromised 6-24 months following surgical treatment of ACL tears compared with healthy controls. The reduced kinesthetic awareness after ACL surgery is of high relevance for optimizing individual treatment plans in these patients. As the current literature is still scarce about the exact underlying mechanisms, further research is needed.

Meta-Analysis
BACKGROUND
Falls are a major problem in public health since they are an important cause of morbidity and mortality. To evaluate the risk of fall and prescribe preventive interventions may be a challenging task.
OBJECTIVES
The objectives of this study are to summarize the most relevant information on the topic "falls in the elderly" and to give a critical view and practical clinical approach on this topic.
METHODS
In March 2022, a search of Pubmed database was performed, using the terms "fall elderly", fall prevention", "fall risk", with the following parameters: five years, review, systematic review, meta-analysis, practice guidelines.
RESULTS
There are several risk factors for falls that can be grouped in different areas (psychosocial, demographic, medical, medication, behavioral, environmental). The clinical evaluation of an older adult prone to falls must include identification of risk factors through history and examination and identification of risk of falls through an assessment tool such as gait velocity, functional reach test, timed up and go, Berg balance test, and miniBEST test. Fall prevention strategies can be single or multiple, and physical activity is the most cited. Technology can be used to detect and prevent falls.
CONCLUSION
A systematic approach to the older patient in risk of falls is feasible and may impact fall prevention.

Meta-Analysis Review
BACKGROUND
In the last few years, virtual reality (VR) has been increasingly used to strengthen the effect of balance training (BT) in Parkinson's disease (PD).
OBJECTIVE
We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) to compare the effects of VR-BT relative to BT alone for improving balance and mobility PD subjects with balance/mobility difficulties.
METHODS
Four electronic databases were searched: two reviewers independently selected RCTs, extracted data, and applied the Cochrane risk-of-bias tool for randomized trials (version 2) and the GRADE framework for assessing the certainty of evidence. Primary outcomes were balanced (Berg Balance Scale-BBS), mobility (Timed Up and Go-TUG) and walking speed. Secondary outcomes were falls, walking distance and stability, spatial gait parameters, balance confidence, sensory integration ability, motor signs and quality of life.
RESULTS
We included 22 studies (901 patients). Meta-analysis on fourteen trials (430 patients) showed a mean difference (MD) of 2.09 points (95% confidence interval [CI] 0.86-3.33) on BBS favoring VR-BT compared to BT (low certainty evidence). Subgroup analyses showed higher balance improvement in most affected subjects (moderate certainty evidence) and using VR rehabilitation-specific systems vs. VR non-specific systems. Eight trials (236 patients) assessing mobility showed a MD of 1.55 s (95% CI 0.04-3.06) on TUG favoring VR-BT (very low certainty evidence). No differences were observed in walking speed. Estimated effects were not maintained for any outcome at follow-up.
CONCLUSIONS
This review suggests that VR-BT is more effective than BT to improve balance in PD subjects immediately after training, particularly in individuals with higher postural instability at baseline.

INTRODUCTION
Vertigo is a debilitating symptom, leading to increased healthcare utilization and lost patient productivity. Vestibular rehabilitation is used to manage the symptomatic manifestations of vestibular disease. However, vestibular rehabilitation is limited by accessibility and time commitment. Recently, virtual reality has been described as a vestibular rehabilitation tool that may circumvent these barriers to treatment. Despite this, the efficacy of virtual reality for vestibular rehabilitation remains unclear. This study aims to review and summarize the current literature on the effectiveness of virtual reality-based vestibular rehabilitation.
METHODS
A systematic review of the MEDLINE, EMBASE, and Alternative and Complementary Medicine databases was conducted for prospective studies describing virtual reality-based vestibular rehabilitation.
RESULTS
Our search identified 382 unique articles. Six randomized controlled trials and four other studies were ultimately included. Study sample sizes ranged from 13 to 70 participants and varied in diagnoses from any unilateral peripheral vertigo to specific pathologies. Different virtual reality interventions were used. Comparator groups ranged from supervised vestibular rehabilitation to independent Cawthorne-Cooksey exercises. Outcomes consisted of validated questionnaires, objective clinical tests, and measurements of balance or reflexes.
CONCLUSION
The studies reviewed in this study are preliminary evidence to suggest the benefit of virtual reality-based vestibular rehabilitation. However, these studies are limited by their inclusion criteria, heterogeneity, comparator design, and evidence-based clinical outcomes. Further research should address these limitations.
