Effects of EMG-Biofeedback Balance Training on Hoffman's Reflex and Their Longevity

The purpose of this study is to gain a further understanding of the effects of EMG-biofeedback balance training and we will be analyzing changes in spinal reflex excitability by responses from the calve muscles and data about your standing balance. The EMG-biofeedback balance training has the potential to improve balance of older adults and prevent future falls and in this study we will learn if it also creates changes in the nervous system. This study aims to 1) determine the effects of a one-month long EMG-biofeedback balance intervention on the H-reflex amplitude, 2) determine whether there is a related behavioural change in the control of balance and 3) determine whether changes in balance and H-reflex amplitude persist for up to two weeks following the end of the balance training intervention.
