The MyOnyx 4-Channel Encoder System is a portable, rechargeable diagnostic and rehabilitation device designed for surface EMG biofeedback (SEMG) and electrical muscle stimulation (ESTIM). It offers four fully customizable electrical stimulation outputs and advanced biofeedback capabilities.

Key features and benefits:

• Electrical stimulation: 4 fully configurable electrical stimulation channels.
• SEMG Surface Electromyography: 2 channels with a wide range of feedback types.
• Simple or detailed control, processing, and reporting modes.
• Measures muscle activation effort and helps users learn to relax or activate their muscles.

The device records 2,048 measurements per second from the muscle, providing an almost real-time view of muscle activity.

What it measures: It measures electrical muscle activity (EMG) using electrodes that record electrical activity from the skin.

Applications: Used for:

• Neurological rehabilitation.
• Rehabilitation after a stroke.
• Motor skills retraining.
• Rehabilitation following orthopedic injuries.
• Relaxation training for chronic pain.

EMG biofeedback threshold: The threshold is the level of muscle activation set as a target for the patient. The device provides immediate feedback once this threshold is exceeded.
