electromyographic biofeedback

Electromyographic biofeedback

A method for relieving jaw tightness by monitoring the patient's attempts to relax the muscle while the patient watches a gauge. The patient gradually learns to control the degree of muscle relaxation.

electromyographic biofeedback

[-mī′əgraf′ik]

a therapeutic procedure that uses electronic or electromechanical instruments to measure, process, and feed back reinforcing information with auditory and visual signals accurately. It is used to provide information about muscle activity during ambulation, for example, in clients with brain injury, stroke, or cerebral palsy.

electromyographic biofeedback (i·lekˈ·trō·mīˈ·ō·graˑ·fik bīˈ·ō·fēdˑ·bak),

n therapy in which sensors are placed on the skin in order to detect tension-related electrical activity. A biofeedback instrument translates the electrical activity levels into a description of the varying degrees of muscle tension. Often used to treat tension headaches.

biofeedback,

n the instrumented process or technique of learning voluntary control over automatically regulated body functions; useful in the treatment of bruxism, temporomandibular joint dysfunction, and pain, and in facilitating anxiety control in the dental setting.

biofeedback, electromyographic (EMG)

n an instrumented process that helps patients learn control over muscle tension levels previously under automatic control; especially useful in treatment of dental disorders such as bruxism, temporomandibular joint dysfunction, tension headaches, and other disorders involving the mus-cles of mastication. In addition to neuromuscular education, electromyographic type is useful in treating dental phobias and anxiety and facilitating pain control by helping patients learn deep-muscle relaxation techniques.

biofeedback, temperature,

n an instrumented learning process whereby a patient learns to control temperature of body parts. Training in self-controlled vasodilation (handwarming) technique has been found useful in treating migraine headaches and anxiety in dental patients.
