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.

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.

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.

Tai chi is a viable adjunct to improve balance in patients who complete a vestibular rehabilitation therapy programme.
