In 2004, a study conducted by Helen S. Cohen, et. al., researchers aimed to evaluate the effectiveness of vestibular rehabilitation exercises on improving performance in purposeful activities among individuals suffering from chronic vertigo caused by peripheral vestibular weakness. While numerous studies have explored the efficacy of vestibular rehabilitation in alleviating vertigo and disequilibrium, few have delved into its effects on purposeful activities.

The study, conducted at a medical school practice and tertiary care facility, involved 53 patients with chronic vertigo. These individuals participated in vestibular rehabilitation exercises targeting head movements to habituate vertigo, categorized into slow or rapid movement groups.

Key findings from the study revealed significant improvements across both groups in terms of reduced time taken to complete repetitive head movement tasks and decreased intensity of elicited vertigo. These improvements were also associated with enhanced independence in activities of daily living and decreased overall vertigo severity.

Importantly, the study concluded that the speed of treatment exercises did not significantly impact the observed improvements. Regardless of whether participants engaged in slow or rapid movement exercises, vertigo symptoms decreased, and head movement speed improved following the vestibular rehabilitation program.

The implications of these findings suggest that even simple purposeful activities can serve as valuable indicators for evaluating the effectiveness of vestibular rehabilitation. By demonstrating tangible improvements in task performance and symptom severity, this research underscores the importance of incorporating purposeful activities into the assessment of rehabilitation outcomes for individuals with vestibular disorders.
