PMID 35937631WHAT IT FOUND
Weekly supervised vestibular rehab improved walking speed and balance over 4 weeks.
A single initial session plus home exercises did not produce significant changes in these measures. The weekly group showed faster Timed Up and Go times, while the single-session group did not.
Key findings
01The weekly supervised group showed significant improvement in Timed Up and Go, Dynamic Gait Index, and Functional Gait Assessment scores after 4 weeks.
02The single-session group showed no significant change in Timed Up and Go, Dynamic Gait Index, Functional Gait Assessment, or balance confidence scores after 4 weeks.
03The rate of change in Timed Up and Go times was significantly better in the weekly group compared to the single-session group.

What it does not show
The study was retrospective with a small sample size (22 patients). Baseline DGI and FGA scores differed significantly between the two groups, with the single-session group starting lower, which may affect comparison of improvement. Adherence to the home exercise program was not monitored or reported. The causes of vestibular hypofunction were varied (neuritis, Hunt syndrome, etc.) and not uniform. The follow-up period was only 4 weeks, so long-term effects are unknown.

The easy way to misread this
Do not conclude that home exercises are ineffective. The single-session group did not improve significantly, but they did show numerical trends. The lack of significant change could be due to the small sample size, lower baseline function, or poor adherence, none of which were controlled for. The study compares frequency of supervision, not the value of the exercises themselves.
