Biofeedback (BFB) has been practiced in clinical settings since the 1970’s, and has become a commonly used treatment in stroke rehabilitation. Normal regulation of muscle tone following a stroke is disrupted by central neuronal damage, which can result in decreased muscle functioning. Although the patient may have some preserved central motor pathways that remain relatively unaffected, these pathways are often unused. Individuals may learn how to use these preserved pathways with the help of electromyographic biofeedback (EMG-BFB). The use of EMG-BFB as an effective means of treatment for upper and lower extremity hemiparesis has been studied, given that hemiparesis of the lower extremity can result in functional disability following stroke and can affect important aspects of daily living (i.e. feeding and dressing).
