A 12-week balance training program combining tai chi and strength training (TCST) can effectively improve balance and aerobic capacity in patients with end-stage osteoarthritis who are awaiting hip surgery. A total of 81 patients aged from 60 to 69 years old were randomly divided into two groups: a training group (TG) and a control group (CG). Participants in TG performed TCST at home under their family’s supervision for 12 weeks. After 12 weeks of training, the mean distance travelled in a six-minute walk was found to have increased from 409 metres to 478 metres in the TG, and the mean ‘Timed Up and Go’ test score had also significantly improved from 18.53 to 14.61. Self-reported functional status scores were also reported to have improved from 40.97 to 36.28, although there were no significant changes in pain or hip motion scores, meaning that hip surgery was still necessary.
