Abstract

Background

Older adults and individuals with neurological disorders often experience balance impairments, which increase their risk of falling and compromise their functional independence. Numerous studies and systematic reviews have investigated the use of non-invasive stimulation techniques for fall prevention and balance control across various populations and device types.

Objective

To conduct an overview of systematic reviews assessing the efficacy of non-invasive stimulation techniques for fall prevention and balance control improvement in different target populations.

Methods

The review protocol was registered in the PROSPERO database (CRD420251023003). A systematic search was conducted for systematic reviews published up to March 2025. Reviews evaluating the efficacy of non-invasive stimulation techniques (i.e., non-invasive brain stimulation (NIBS), neuromuscular electrical stimulation (NMES), galvanic vestibular stimulation (GVS), and mechanical stimulation) on fall prevention or balance control in older adults or individuals with neurological disorders were included. The AMSTAR 2 tool was used to assess the methodological quality of the included reviews. Overall and subgroup meta-analyses were performed using random-effects models, with the standardized mean difference (SMD) as the effect size measure.

Results

We identified 21 systematic reviews. Three reviews (including one with a meta-analysis) were excluded from qualitative synthesis due to “low/critical low” quality. The remaining 18 reviews were included in the qualitative analysis, encompassing 328 original studies, which involved 11,692 participants. Of these, 13 reviews were included in the quantitative synthesis, of which 12 were pooled in the meta-analysis. The pooled results showed that non-invasive stimulation techniques had a moderate effect on improving balance control (SMD = 0.43, 95% CI, 0.34–0.52; = 8%, p = 0.366). Funnel plot inspection and Egger’s test (p = 0.267) indicated no evidence of publication bias. Subgroup analyses showed no statistically significant differences: by type of balance outcome (static vs. dynamic, p = 0.777), non-invasive stimulation techniques (p = 0.857), or target population (individuals with stroke or Parkinson’s disease, p = 0.750).

(Without even mentioning what the hell non-invasive interventions are; TOTALLY FUCKING USELESS! Don't your mentors and senior researchers have any clue how to do research?)

Conclusions

Non-invasive stimulation techniques may serve as a moderately effective(NOT GOOD ENOUGH!) therapeutic strategy for improving balance control, with potential functional benefits. The quality of evidence was moderate for NIBS but low for NMES and GVS. However, their clinical relevance should be interpreted with caution. The effectiveness in fall prevention remains to be established due to limited available evidence.
