Biofeedback training in clinical cardiovascular disease
Biofeedback mechanisms have been shown to be effective in treating mild hypertension. Various forms include binary feedback training to lower blood pressure and heart rate, analogue feedback to control forearm and frontalis electromyographic activity, and meditation-relaxation procedures. The simple technique of having the patient take his own blood pressure and consciously attempt to lower it by whatever mechanism he can is quite effective. Thermal feedback training to control migraine headaches and Raynaud's disease has been successful. Autogenic training to control skin temperature is also an effective instrument.
