A systematic review about the effects of the vestibular rehabilitation in middle-age and older adults

Objective: To summarize the results of clinical trials on vestibular rehabilitation (VR) in middle-aged and elderly people with vestibular disorders. Methods: A search for relevant trials was performed in the databases LILACS, EMBASE, MEDLINE, SciELO, Cochrane, ISI Web of Knowledge and virtual libraries of theses and dissertations. Randomized controlled trials published in the last 10 years and written in English, Portuguese or Spanish were included. The methodological quality of the studies was assessed by the PEDro scale. Results from the included studies were analyzed through a critical review of content. Results: Nine studies were included in the review. Four studies reported on participants aged over 40 years (middle-aged and elderly) and five studies consisted exclusively of elderly subjects (over 60 years). Findings of vestibular dysfunction were diverse and the most common complaints were body imbalance or postural instability (3 studies), and vertigo or dizziness (3 studies). The Visual Analogue Scale (VAS) was the most commonly used instrument to assess subjective perception of symptoms of vestibular dysfunction (4 studies). According to the PEDro scale, four studies were considered to be of good quality. The most common experimental intervention was the Cawthorne & Cooksey protocol (4 studies). For most outcome measures, the studies comparing VR with another type of intervention showed no differences between the groups after the therapy. Conclusions: The studies included in this review provide evidence for the positive effects of VR in elderly and middle-aged adults with vestibular disturbances.
