Reactive Balance Training Targeting Both Slip- and Trip-Induced Falls

Not Applicable
Completed
Conditions
Accidental Fall
Registration Number
NCT04308239
Lead Sponsor
Virginia Polytechnic Institute and State University
Brief Summary

The goal of this study was to evaluate the effects of reactive balance training (RBT) targeting slipping and tripping on laboratory-induced slips and trips. In an effort to build upon prior work, the present study included: 1) a control group receiving an alternative balance training intervention; 2) separate training and assessment sessions; 3) alternative RBT methods that may be more amenable to work outside the lab compared to prior methods, and 4) older adult participants receiving individualized training to reduce drop-out. The investigators hypothesized that slips after RBT would result in improved reactive balance kinematics, and a lower incidence of falls, compared to either initial slips before any intervention or after a control intervention. The investigators also hypothesized that trips after RBT would result in improved reactive balance kinematics, and a lower incidence of falls, compared to either initial trips before any intervention or after a control intervention. Results were intended to contribute to knowledge regarding the efficacy of alternative methods for RBT, and provide additional evidence regarding its efficacy.
