Comparison between two therapeutic modalities on postural balance and fear of falling in postmenopausal women: a randomized and controlled clinical trial

Abstract To compare the effects of Pilates vs. whole body vibration (WBV) and no treatment controls on postural balance and fear of falling in postmenopausal women. Method: Single-blind randomized clinical trial, with 51 participants randomized into three groups (Pilates, WBV, or control). Evaluations were performed of static postural balance on a force platform, dynamic postural balance by the Timed Up & Go test, and fear of falling by the Falls Efficacy Scale-International (FES-I). Pilates and WBV were performed three times a week for six months. Results: After the intervention, no difference (p>0.05) was observed for static postural balance, however, for the majority of variables, Pilates and WBV demonstrated a large effect size (d>0.80) when compared to control. For dynamic postural balance and risk of falls, Pilates and WBV showed a significant (p=0.032) improvement compared to the control. Fear of falling did not change (p=0.055) between groups over time. Conclusion: In view of the clinical representativeness evidenced by the effect sizes, Pilates and WBV can be recommended to improve postural balance in postmenopausal women. However, in relation to fear of falling, these therapeutic modalities require further investigation.
