RESUMO
OBJECTIVE: This study aimed to evaluate the effectiveness of tai chi on balance in patients with improved but persistent dizziness and imbalance following completion of traditional vestibular rehabilitation therapy. METHOD: Patients who completed vestibular rehabilitation therapy with persistent imbalance were prospectively enrolled in a tai chi programme comprising eight weekly classes. Balance was assessed before the first and after the eighth session using the Dynamic Gait Index, Activities-Specific Balance Confidence scale and Dizziness Handicap Inventory. RESULTS: A total of 37 participants (34 females, 3 males) completed the programme with balance testing. Mean age was 76.8 years (range, 56-91 years). Mean Dynamic Gait Index significantly increased after completion of tai chi (p < 0.00001). Mean Activities-Specific Balance Confidence scale score increased from 63.6 to 67.9 per cent (p = 0.046). A subset (n = 18) of patients completed a Dizziness Handicap Inventory without significant post-therapeutic change (p = 0.62). Most (36 of 37; 97.3 per cent) patients demonstrated post-therapy improvement on one or more assessments. CONCLUSION: Tai chi is a viable adjunct to improve balance in patients who complete a vestibular rehabilitation therapy programme.
