Background: Falling and fear of falling are among the most common problems of the elderly, which can cause illness, isolation, dependency and reduced quality of life in elderly. Exercise is recommended to prevent falling injuries in the elderly. Aim: This study aimed to examine the effect of Tai Chi exercise on the risk and fear of falling in older adults.

Tai Chi exercise protocol in the intervention group consisted of 3 sessions per week for 10 weeks. The risk and fear of falling were assessed in subjects by using standardized questionnaires, including Bergs Balance Scale and Fall Efficacy Scale-International (FES-I) before initiating the protocol, at the end of 4th, 8th weeks and at the end of exercise period. Results: Two groups were matched in terms of age, gender, education, and body mass index.
