MyoTrac™ packs extreme sensitivity into a light, compact unit that works for you and your patient in the clinic or home. It is ideal for clinical assessment as well as for self-training. MyoTrac™ allows total freedom of movement for ambulatory exercises and provides a bright light bar and proportional tone biofeedback. The unit is accurate and reliable. MyoTrac™ offers three sensitivity ranges for muscle strengthening, rehabilitation or relaxation therapy, and provides stable readings in less than a second.


  • The highly-sensitive active MyoScan sensor needs no skin preparation to locate muscle sites quickly
  • Two modes of biofeedback - LED and 5 way tone - provide flexibility
  • 5 way tone feedback includes proportional, above and below threshold and 4-second delayed alarm
  • 13-segment LED bargraph offers expanded range for precise visual feedback
  • Wide and narrow bandpass filters provide precise monitoring of normal and fatiguing muscles and eliminate heart-beat artifact
  • 0 to 2 Volts DC output allows to connect to third party equipment and permits computerized monitoring
  • Low current consumption provides long battery life
