Objective:

To determine the effectiveness of exercise in improving sensorimotor function and functional performance, crucial parts of activities of daily living in healthy older adults.

Design:

RCT.

Setting:

Laboratory.

Participants:

39 subjects (M = 71.8 years, range: 61–89 years).

Intervention:

Task-oriented visual feedback balance training.

Primary outcome measure:

Timed Up & Go (TUG).

Secondary outcome measures:

Chair stand test (CST), self-paced walk test, maximum isometric torque, quiet stand posturography, and dynamic balance (DB).

Results:

Postintervention comparison of the treatment group (TG) and control group (CG) showed better TUG (p < .01), CST (p < .001), and DB (p < .025) for the TG. Pre–post intervention comparison of the TG showed better clinically-relevant outcomes in TUG (p < .001), CST (p < .001), and DB (p < .001).

Conclusion:

Active driven visual feedback balance training is effective in improving functional performance and dynamic balance in older adults.
