MyoTracTM

Product catalog summary

Overview
The MyoTrac single-channel EMG device combines sensitivity with ease of use, suitable for both clinical and home environments. It is designed for muscle strengthening, rehabilitation, and EMG relaxation, featuring versatile sensitivity ranges and feedback mechanisms.

Key Features

Biofeedback Modes: Offers two modes - LED and 5-way tone feedback, including proportional, above and below thresholds, and a 3-second delayed alarm.
Visual Feedback: A 13-segment LED bargraph provides precise visual feedback.
Filtering: Wide and narrow filters allow for precise monitoring of muscle activity and eliminate EKG artifacts.
Threshold Options: Signals EMG activity that exceeds or falls below set thresholds.
Connectivity: DC voltage output for accessory connection and computer monitoring.
Sensor: The MyoScan sensor is highly sensitive and requires no skin preparation for quick muscle site location.
