Comparison of multisensory and strength training for postural control in the elderly

OBJECTIVE The objective of this study was to analyze the efficacy of multisensory versus muscle strengthening to improve postural control in healthy community-dwelling elderly. PARTICIPANTS We performed a single-blinded study with 46 community-dwelling elderly allocated to strength (GS, n = 23; 70.18 ± 4.8 years 22 women and 1 man) and multisensory exercises groups (GM, n = 23; 68.8 ± 5.9 years; 22 women and 1 man) for 12 weeks. METHODS We performed isokinetic evaluations of muscle groups in the ankle and foot including dorsiflexors, plantar flexors, inversion, and eversion. The oscillation of the center of pressure was assessed with a force platform. RESULTS The GM group presented a reduction in the oscillation (66.8 ± 273.4 cm(2) to 11.1 ± 11.6 cm(2); P = 0.02), which was not observed in the GS group. The GM group showed better results for the peak torque and work than the GS group, but without statistical significance. CONCLUSION Although the GM group presented better results, it is not possible to state that one exercise regimen proved more efficacious than the other in improving balance control.
