Falls prevention for frail older adults: Cost-efficacy analysis of balance training based on Tai Chi

INTERVENTION: Experimental group: Tai Chi intervention includes two sessions of one hour per day for 15 weeks. The intervention is based on movement using body alignment and specific weight transfers in different directions. 10 movements compose the sequence of Tai Chi. Moreover, the subjects are trained to relaxation and breathing exercises. The intervention is given in groups of 4 to 6 subjects. Since subjects present specific disabilities, the intervention is adapted in order to be at the limit of the capacities for each individual in a secure way. Feedback is given at each session. Control group: Conventional physiotherapy balance training is given to subjects of the control group for two sessions of one hour per day for 15 weeks Trial details received: 12 Sept 2005 CONDITION: Any diagnosis causing the loss of autonomy; falls in elderly adults ; Injury, Occupational Diseases, Poisoning ; Falls PRIMARY OUTCOME: Incidence rate on fall in one year of follow‐up SECONDARY OUTCOME: 1.
