INTRODUCTION
Balance and postural control are related to hearing and hearing loss, but whether they can be improved with hearing aid use in older adults is not clear. We systematically reviewed controlled studies in which balance and hearing were tested in experienced older hearing aid users to determine the potential effects of hearing aid use on balance.
METHODS
The review was pre-registered in PROSPERO and performed in accordance with PRISMA. The question, inclusion, and exclusion criteria were defined using the Population, Intervention, Control, Outcomes and Study design (PICOS) framework. Older adults with hearing loss and no experience with hearing aids, or balance tests conducted without hearing aids in hearing aid users served as controls.
RESULTS
A total of 803 studies were screened, eight of which met the inclusion and exclusion criteria and were included in the final review. Five of the eight studies found a significant correlation between the use of hearing aids and the outcomes of the balance tests. The quality of the studies was limited or moderate. Key Discussion: The role of hearing aids in balance and postural control is unclear because of the quality of the papers and the sparse reporting of hearing status and hearing aids quality of fitting and use.

Meta-Analysis
OBJECTIVE
Previous studies' results on the impact of preoperative balance training on postoperative functional recovery after total knee arthroplasty (TKA) appeared to be ambiguous. Thus, this systematic review and meta-analysis were performed to investigate the effects of preoperative balance training on walking ability, balance-specific performance, and other functional indicators in elderly patients post-TKA.
MATERIALS AND METHODS
Patient data were obtained from databases including PubMed, Physiotherapy Evidence Database (PEDro), CINAHL, SPORTDiscus, and Scopus. The inclusion criteria followed the Population-Intervention-Comparison-Outcome (PICO) principle. The assessment process involved meticulous screening, judicious data extraction, and rigorous evaluation of trial method quality, conducted by two independent researchers. Based on standardized mean differences and 95% confidence intervals, meta-analysis was performed employing a random-effects model or fixed-effects model.
RESULTS
Preoperative balance training appears to be a potentially effective intervention for enhancing the knee osteoarthritis (KOA) patients' knee joint function (RR = 1.16, 95% CI: -2.58, 4.91), isometric knee flexion (RR = 2.49, 95% CI: -2.53, 7.50), knee extension (RR = -0.13, 95% CI: -0.45, 0.18), knee society score (KSS) (RR = 2.18, 95% CI: -1.51, 5.88), stair test (RR = -0.73, 95% CI: -1.84, 0.37), and timed up and go (RR = -1.18, 95% CI: -1.60, -0.76).
CONCLUSIONS
Compared to interventions with less emphasis on balance training, rehabilitation programs highly emphasizing balance training significantly enhance the walking ability, balance specificity, and functional indicators of elderly patients post-TKA. This includes rehabilitation programs for senior TKA patients, with a focus on activities meant to improve the sensory system, balance in particular.

Meta-Analysis
INTRODUCTION
Postural balance impairment can affect the quality of life of patients with Parkinson's disease. Previous studies have described connections of the vestibular system with postural functions, suggesting a potential participation of the basal ganglia in receiving vestibular stimuli. This systematic review aims to summarize the evidence on the effectiveness of vestibular rehabilitation on postural balance in patients with Parkinson's disease.
METHODS
A systematic review was conducted using the electronic databases: PubMed, Embase, Scopus and PEDro. The study selection was independently conducted by two reviewers, and disagreements were evaluated by a third reviewer. The included studies had no restrictions on publication dates or languages and the last update occurred in July 2023.
RESULTS
From the 485 studies found in the searches, only 3 studies were deemed eligible for the systematic review involving a total of 130 participants. The Berg Balance Scale was described as the tool for evaluation of postural balance in all studies. The meta-analysis showed statistically significant results in favor of vestibular rehabilitation (MD = 5.35; 95% CI = 2.39, 8.31; P < 0.001), regardless of the stage of Parkinson's disease. Although the effect size was suggested as a useful functional gain, the analysis was done with caution, as it only included 3 randomized controlled trials. The risk of bias using the RoB-2 was considered as being of "some concern" in all studies. Furthermore, the quality of the evidence based on the Grading of Recommendations Assessment Development and Evaluation system, produced by pooling the included studies was considered very low.
CONCLUSION
Compared to other interventions, vestibular rehabilitation has potential to assist the postural balance of patients with Parkinson's disease. However, the very low quality of the evidence demonstrates uncertainty about the impact of this clinical practice. More robust studies are needed to confirm the benefits of this therapy in patients with Parkinson's disease. This study was prospectively registered in PROSPERO: CRD42020210185.

Meta-Analysis
OBJECTIVE
Loss of functional independence is more likely in older adults who reside in an institution as a consequence of a decline in muscle mass and a loss of force production capacity. The aim of this review was to assess the effect of whole-body vibration (WBV) interventions on the strength, balance, and mobility of nursing home residents older than 80 years.
METHODS
An electronic search in MEDLINE, Scopus, and CINAHL databases was conducted. Randomized controlled trials that involved nursing home residents older than 80 years, that investigated WBV interventions compared with nonintervention, usual care, or placebo, and that measured physical function outcomes including strength, balance, gait, and mobility were included. Risk of bias was assessed by 2 reviewers using the Physiotherapy Evidence Database scale. The standardized mean differences (SMD) between the experimental and control groups were calculated with a random-effects model for each outcome, and subgroup analysis was conducted for different outcomes.
RESULTS
In total, 2864 articles were identified; of these, 14 randomized controlled trials met the inclusion criteria. The meta-analysis revealed that WBV significantly increased the lower limb muscle strength (SMD = 0.59; 95% CI = 0.16 to 1.03), mobility (SMD = 0.45; 95% CI = 0.10 to 0.81), gait score (SMD = 0.26; 95% CI = 0.01 to 0.51), balance (SMD = 0.41; 95% CI = 0.01 to 0.81), and physical performance (SMD = 1.33; 95% CI = 0.33 to 2.33).
CONCLUSION
WBV may be an effective intervention to improve the strength, balance, mobility, walking ability, and physical performance of older nursing home residents.
IMPACT
WBV presents a safe, accessible alternative for improving health in this vulnerable population, warranting further research and integration into health care practices.

OBJECTIVE
The effect of fall prevention exercise programmes in residential aged care (RAC) is uncertain. This paper reports on an intervention component analysis (ICA) of randomised controlled trials (RCTs), from an update of a Cochrane review, to develop a theory of features of successful fall prevention exercise in RAC.
METHODS
Trial characteristics were extracted from RCTs testing exercise interventions in RAC identified from an update of a Cochrane review to December 2022 (n=32). Eligible trials included RCTs or cluster RCTs in RAC, focusing on participants aged 65 or older, assessing fall outcomes with stand-alone exercise interventions. ICA was conducted on trials with >30 participants per treatment arm compared with control (n=17). Two authors coded trialists' perceptions on intervention features that may have contributed to the observed effect on falls. Inductive thematic analysis was used to identify the key differences between the trials which might account for positive and negative outcomes.
RESULTS
32 RCTs involving 3960 residents including people with cognitive (57%) and mobility (41%) impairments were included. ICA on the 17 eligible RCTs informed the development of a theory that (1) effective fall prevention exercise delivers by specifically targeting balance and strength, tailored to the individual and delivered simply at a moderate intensity and (2) successful implementation needs to be to deliver structured and supervised exercise at an adequate dose.
CONCLUSIONS
This analysis suggests that delivering the right exercise, sufficiently resourced, is important for preventing falls in RAC. This clinical guidance requires confirmation in larger trials.
