biofeedback bi·o·feed·back (bī'ō-fēd'bāk')
A training technique that enables a person to gain some element of voluntary control over autonomic body functions. It is based on the principle that a desired response is learned when received information indicates that a specific thought or action has produced the desired response.
The technique of using monitoring devices to obtain information about an involuntary function of the central or autonomic nervous system, such as body temperature or blood pressure, in order to gain some voluntary control over the function. Using biofeedback, individuals can be trained to respond to abnormal measurements in involuntary function with specific therapeutic actions, such as muscle relaxation, meditation, or changing breathing patterns. Biofeedback has been used to treat medical conditions such as hypertension and chronic anxiety.
A training technique by which a person learns how to regulate certain body functions, such as heart rate, blood pressure, or brain wave patterns, that are normally considered to be involuntary. The person learns by watching special monitoring instruments attached to the body that record changes in these functions.
Note: Biofeedback has had some success in the treatment of such disorders as chronic headaches and back pain.
