BFB Trainer MIST
BFB Trainer MIST
The biofeedback (BFB) trainer with the electromyostimulation function MIST is a small portable wearable device developed for training paralyzed and weakened muscles using the method of biological feedback (BFB by electromyography) and physiotherapeutic neuromyostimulation and electrotherapy (myostimulation sessions for the purpose of muscle relaxation or activation).
Description
The user version of the device (BFB trainer with electromyostimulation function) MIST allows to work in 2 possible modes:
- «Trainer»: conducting individual therapeutic sessions of EMG-BFB training for paralyzed and weakened muscles;
- «Electrotherapy»: conducting myostimulation sessions for relaxation or activation of muscles according to special programs.
System capabilities
In the «Trainer» mode the device is used to conduct individual therapeutic EMG-BFB-training sessions for paralyzed and weakened muscles (consequences of strokes, cerebral palsy, injuries to nerve trunks and spinal cord, facial nerve neuritis, postural disorders, etc.).
The patient can conduct training sessions independently without the participation of a physician, preferably after special training by an instructor. The device is both a load dispenser and a "mirror" displaying the actual muscle contractions of the muscles being trained. The fundamental feature is the ability to register minimal muscle contractions that are invisible to the eye (in severe paralysis).
The device does not have any active electrical effect on the body. On the contrary, it serves as a sensor-antenna that records the patient’s own bioelectrical muscular activity – a myogram, which is the equivalent of the power of muscle contractions. By controlling it, the patient has the opportunity to train the affected muscles in conditions where the physiological connection between the muscle and the brain is disrupted.By controlling the power of muscle contractions, just as when performing therapeutic physical exercises, the patient trains the strength of the muscle and creates a "new" reflex connection between the paralyzed muscle and the affected structures of the nervous system.This principle of obtaining additional information about qualitative and quantitative characteristics of the functional activity of the organ being trained in real time is called biofeedback.
When addressing tasks of posture correction and during kinesiotherapeutic interventions, this method is used to form an optimal motor stereotype.
In the «Electrotherapy» mode the device is used to conduct sessions of special myostimulation for the purpose of relaxation or activation of muscles. The mode includes 7 special electrical stimulation programs developed by qualified specialists.
