Alzheimer's Disease Cooperative Study Prevention Instrument Project Assessing Resource Use and Volunteer and Paid Work in Healthy Elders: A Longitudinal Study

The present study showed that the TCB group had greater improvement in their vestibular score (12.1%) than controls (0.51%); there was a significant difference between the TCB and control groups after the 12-month intervention. Practicing TCB involves head movements that could stimulate the vestibular system through head and body rotation and fixation of the eyes on the moving ball during the practice of its many forms. The finding showed that 12 months of TCB exercise improved visual and composite scores. The result is consistent with improvement in balance using tai chi as a form of exercise. The average ABC Scale score of the TCB group increased after 12 months of intervention (mean change 7.3%). This change was similar to that reported in the only other progressive resistance training intervention study to have administered the ABC Scale (mean change 6%). The results suggest that it is possible to recommend a TCB program for 12 months to significantly improve balance confidence. These findings have demonstrated that a TCB intervention was both effective for community-dwelling elderly persons in improving balance performance in relation to falls and might delay the onset of deterioration of motor function. These findings can contribute to the future planning of community-based exercise programs.
