What is a MyoPro Orthosis?

MyoPro is a powered arm and hand orthosis (brace) designed to help restore function to upper extremities paralyzed or weakened by neuromuscular and neurological disease or injury, including:

A breakthrough in modern medical robotics

Originally developed at MIT with Harvard Medical School, the MyoPro arm and hand orthosis device works by reading the faint nerve signals (myoelectric signals) from the surface of the skin (no implants) then activating small motors to move the limb as the user intends (no electrical stimulation).

The user is completely controlling their own hand, wrist, elbow, and arm; the robotic arm brace amplifies weak muscle signals to help move the upper limb. It has been called “power steering for your arm.”

While there are many prosthetic products for those who have lost their arms, hands or legs, and while there are orthotic products to support weak legs, MyoPro is the only wearable robotic device on the market to help restore function for those who still have their arms and hands but are unable to use them.

History of Myoelectric Devices

The first myoelectric prosthesis was created between 1944-1948 by Reinhold Reiter, a physics student at Munich University. Reiter recog­nized that to work properly, the device needed to obtain maximum information from the myoelectric signal. The technology has, over the past 50 years, moved from single muscle control of a single prosthesis function to more complex muscle group activity control of multifunction prostheses. Central to these changes have been developments in the means of extracting information from the myoelectric signal.

Later work expanded the concept of myoelectric control to orthoses for upper extremity impairment. By supporting research in 1990, the VA promoted and inspired development for a future myoelectric orthosis that could be of benefit to Veterans that have upper extremity impairment. In 2006, work in myoelectric upper extremity orthoses at MIT was commercialized resulting in the development of the Myo­Pro myoelectric elbow-wrist-hand orthosis (EWHO).

i-Digits™ Quantum

i-Digits™ Quantum is a customized prosthetic device for individuals with partial hand loss or deficiency. i-Digits Quantum is appropriate for partial hand absence. Suitable candidates present with partial hand loss where the level of loss or deficiency is distal to the wrist and proximal of the metacarpophalangeal joint. Anywhere from one to five digits can be replaced. i-Digits Quantum offers the ability to change grips with a simple gesture.


  • Fully customized prosthesis for partial hand loss or absence
  • Anywhere from 1 to 5 digits can be replaced
  • Up to 32 grips available
  • Form fitting anatomical design
  • Self-contained wristband houses batteries & microprocessor


  • Digits move independently and work in conjunction with remaining fingers
  • Full wrist range-of-movement
  • vari-grip™ feature for enhanced grip strength
  • auto grasp™ anti-drop feature for added reassurance
  • Boost speed and strength by up to 30% with my i-limb™ app

Intelligent motion

Gesture control enables an automated grip to be accessed by moving the i-Digits™ Quantum in one of four directions.

Reclaim all you want to be.

The X3 has now been developed even further for smoother, more intuitive walking, improved safety, and better support in everyday situations. Another plus for you: The new prosthesis is simple to control using the Cockpit app on your iPhone or Android smartphone.*

Building on the unique functionality of the Genium leg prosthesis, the X3 is particularly robust and resilient. Physically demanding occupations, an active family life, swimming and sports activities, seaside holidays and situations where you encounter water, dust, sand, dirt or grime – these are the ideal conditions for the X3.
