Biofeedback and myofeedback

Myofeedback is a form of feedback, in which the patient receives electronically recorded information about his own physiological processes. The electromyographic recording used in the diagnostics and treatment of the moving mechanism is an indispensable supplement to the study of movement. When we place electrodes on the skin to obtain information from an EMG signal about the underlying musculature, we must be acquainted with the development of the EMG signal and the construction and function of the motor mechanism.  Thus, properties and mutations in the musculature, the joints system, the sensory and the neural system can be found in the motor system and also in the EMG recording.

Surface EMG provides us with detailed information about the organ-specific properties of a muscle, such as:

• the activation of the muscle;
• the muscle’s capacity for relaxation;
• coordination between muscles;
• the tiredness of a muscle;
• the capacity of a muscle to lengthen.

This makes myofeedback especially suitable as a measuring instrument for charting our locomotive operations

Biofeedback is the process of gaining greater awareness of physiological functions primarily using instruments that provide information on the activity of those functions, with a goal of being able to manipulate them at will. The Enraf-Nonius Myomed systems allows for biofeedback (besides myofeedback) by means of pressure feedback. This is very usefull for pelvic floor training. Biofeedback is done with cavity probes (vaginal or anal) and gives feedback on the the coordinated action of the pelvic floor muscles. It is a very funtional approach for re-educating and relaxation of the pelvic floor and can solve many highly inconvenient dysfuntions in the pelvic area.
