Biofeedback use of common objects

Abstract
Many common devices can be used as biofeedback devices. The feedback use of the bathroom scale in rehabilitation medicine(physical therapy) has been explored with stroke patients. These patients used two scales, one under each foot, to relearn their sense of weight distribution. In addition, the scale was used to teach patients to shift their weight distribution from their knees to their hands as they learned to crawl, and from their feet to their buttocks and the chair as they learned to sit down.
