Miofeedback technique is a powerful tool in physiotherapy. In everyday life we are constantly guided by feedback or information that modulates our business. The importance of this tool is that it allows us to break the Barrea considered autonomic biological functions with the control of voluntary activity.

Definitions
* Feedback
* Biofeedback – concerning the biological activity – BFB -
* Miofeedback – detects muscle electroactivity

Miofeedback Process
Three electrodes are applied (one makes of indifferent and the other two asset (the remaining two waves captures a positive charge and the other negative charge waves with reference wing neutral or indifferent).

The equipment is extremely sensitive, that detects microvolt levels on the skin from the depolarization of muscle fibers. The miofeedback not represent the muscle activity as an electromyograph, but integrates the signal in half of all muscle activity.

Biofeedback Systems
- For sensory perception (sight, touch, proprioception, balance, etc.).
By mechanical pressure (sphincter pressure).
- Moisture (sweat, urine).
By brain activity.
By temperature.
- Blood pressure.
- For myoelectric activity (miofeedback).
- Strain (elongation and bending).
- For heart rate.
- For respiratory rate.
