H36 Muscular Biofeedback www.biopac.com ©2004 BIOPAC Systems, Inc. Page 1 of 6 BSL PRO Lesson H36: Muscular Biofeedback Lesson developed by: Heather Medema-Johnson, M.S., ATC, CSCS Introduction Biofeedback is a form of self-regulation in which an individual is provided information in the form of sensory feedback about a biological condition or function in order to gain control over that biological function. Biofeedback is often used as a therapeutic tool by which therapists, sports medicine/rehabilitation professionals, neurophysiologists, and psychophysiologists can use electrophysiological instrumentation to measure, process, and “feedback” the recorded information to the subject (client, patient, athlete). The feedback is usually given through auditory and/or visual means. Biofeedback is considered advantageous, as it provides the subject with a chance to use their visual and auditory senses to become more aware of how they are performing during therapy or training, attempt to improve upon it, and immediately see the improvement as it is occurring. Because the subject immediately notes improvements, they are “rewarded.” This reward will hopefully lead to larger improvements and accomplishments. There are many types of biofeedback modalities available. One of the most popular and widely accepted modalities used in a clinical setting is surface EMG biofeedback. EMG (electromyography) bioinstrumentation measures muscle activity by recording electrochemical activity of a muscle occurring during depolarization and recruitment of a skeletal muscle motor unit. This modality is used for muscle reeducation and control when orthopedic injuries or surgeries have taken place, or when the peripheral nervous system has been impaired. It is also used to promote muscle relaxation to decrease muscle guarding, pain, stress, and anxiety. Read more about it… ± Arnheim DD, Prentice, WE. Principles of Athletic Training . 10 th Ed.
