MyOnyx¬†is a portable,¬†handheld¬†and rechargeable device for¬†Surface EMG biofeedback (SEMG), electrostimulation (ESTIM), and¬†EMG ‚Äďtriggered stimulation (ETS).¬†¬† This sleek, easy to use instrument has three functionality modes ‚Äď standalone, remote control using the¬†MyOnyx¬†app (on Google Play) with an Android device or remote control with a computer (Windows software). It comes in two models:¬†


  • Basic(OC-3073-01) unit¬†operates as a standalone or by remote control with an Android device¬†
  • Extended(OC-3073-02) unit¬†operates as a standalone, or by remote control with either an Android device or the¬†BioInfiniti¬†software on a PC.¬†


Both models were developed in consultation with physiotherapists, applying the latest research in neuroplasticity, motor learning, and patient education to provide a device that allows effective, targeted treatment on a case by case basis. 


The¬†standalone mode¬†delivers¬†preset¬†ESTIM¬†session types directly from the device interface with up to 4¬†channels and¬†has a range of tools for flexibility in treatment options. The ‚Äėtap and go‚Äô feature runs an ESTIM session without selecting a specific client. The¬†Dual Exercise¬†mode will run two¬†ESTIM sessions at the same time. Select a NMES session from the ESTIM protocols, using one of the feedback options ‚Äď games,¬†music¬†or animation. Each session type is defined by its duration, the number of work/rest steps, the ramp up or down times and the pulse rates and width. Note:¬†ESTIM sessions are not recorded.¬†


The MyOnyx app increases and expands the device capabilities: 


  • Edit and customize the pre-set¬†ESTIMsessions for individual patient needs.¬†¬†
  • Plan a¬†Biofeedback¬†session with one of four display types (line, bar,¬†animation¬†or pattern). Sessions can be defined for 1 or 2 channels and can be saved to a¬†client database.¬†Note:¬†the app shows EMG RMS only.¬†
  • Combine biofeedback with ESTIMusing the¬†EMG triggered STIM. A¬†NMES¬†session is delivered when client‚Äôs muscle voluntary contraction reaches threshold determined by therapist.¬†¬†


The Client Database on the MyOnyx app is designed to protect patient confidentiality. It requires a username and password, and gives the user access to their patients only. Multiple sessions for each patient can be saved to the database. 


The MyOnyx Rehab Solution is a Biograph Suite that offers tools for muscle function assessment and biofeedback training. 


Assessment Protocols include five activity assessments for 2 EMG channels and for 1 channel EMG. Assessments include pre-baseline rest, maximal contraction, fact flick, endurance, and post-baseline rest, and take just over 4 minutes to run. 


Conduct an open assessment with 2 EMG channels by monitoring client’s EMG activity in specific movements.  Conduct an assessment with 1 EMG channel and median frequency (to assess fatigue).


Training Protocols include a complete suite of biofeedback protocols using 1 channel or 2 channels of EMG, or 1 channel and 1 channel of EMG.  Use protocols to measure muscle activation efforts or teach relaxation or fine motor control: 


  • Activating Ch 1 while relaxing CH 2
  • Control
  • Control with extra channel
  • Relaxation with 1 or 2 channels
  • Strengthening with 1 or 2 channels.
