简要总结
In the past years, several studies have demonstrated the potential of task-specific perturbation-based balance training (PBT) for preventing falls at age. However, different paradigms of PBT have been investigated so far, while a comparison of these paradigms is lacking. Therefore, in this study, we plan to compare two promising PBT approaches in terms of feasibility and effects on fall risk-associated motor performance: 1. Training of dynamic stability mechanisms in the presence of perturbations induced by unstable surfaces; 2. Technology-supported training on a perturbation treadmill. In addition, both approaches will be compared with a passive control group. One-hundred and eleven participants aged 65 years or older will be randomly assigned to the three arms of the study. As the primary outcome, we will assess fall risk by use of the Brief-BESTest. Secondary outcomes include balance performance, functional performance, force capacity, and more. We hypothesize that both interventions will lead to a significant reduction of fall risk compared to the control group. Additionally, we will explore whether one of the two PBT paradigms is superior regarding feasibility and effectiveness.
