Myomo mPower 1000

Myomo, which stands for “My Own Motion”, is the first wearable, portable robotic device to help stroke survivors relearn how to move affected arms using their own muscle signals. The Myomo neuro-robotic arm brace uses EMG technology to sense electrical pulses from the patient’s own muscles and then helps to complete the desired movement.

This assists recovery (re-teaching arm movement to the brain) and allows for greater self-reliance


The Myomo NeuroRobotic System is a new category of medical device technology designed to help individuals relearn how to move partially paralyzed arms after stroke. Myomo employs advanced NeuroRobotics technology to allow individuals to self initiate and control movement of affected limbs using their own biological signals.


The lightweight, portable robotic device is worn on a patient's arm. A sensor that sits on the skin's surface is used to detect a person's muscle signal as he or she attempts movement. When muscles fire, the signal is processed to the robot to assist the person in achieving movement of the affected arm. The device facilitates goal-oriented training in seated, standing or ambulatory activities depending on patient ability.
The technology was invented by MIT scientists who established Boston-based Myomo, Inc. to introduce the innovation to the stroke community at large after years of development.

With the help of Myomo you can move your arm effortlessly throughout your daily activities.


Reinforcement is the key to improving motor function in an affected upper extremity."
With a determined focus on usability, therapists can now easily customize the level of assistance, greatly reducing stagnation and plateaus in patient recovery.

The system consists of a portable elbow brace made of a lightweight aerospace metal, and includes advanced robotics processing software, noninvasive surface sensors for biceps and triceps, and a lightweight battery unit. The Myomo System employs a feedback-based closed loop system, which facilitates muscle re-education by assisting the patient with desired motion in concert with his or her own muscular activation. The process enables the brain to re-map motor pathways following an injury.

What a Patient Session Would Entail


First, padding is used to customize the device to fit each patient.
Next, the sensor is placed on the skin’s surface above the muscle group that the treatment tasks will focus on. For example, if the therapist is working on feeding, the sensor would be placed over the bicep. If the therapist is working on using the upper extremities to help push up from a sitting position to standing, the sensor would be placed over the tricep.


Then, with the push of a button, the device automatically calibrates in approximately 10 seconds using the electrical muscle activity signal that it reads from the patient’s muscle group.
Lastly, the therapist can quickly set the amount of assist that is needed for the task based on patient ability.


During therapy, the therapist can also easily adjust the level of power assist based on the patient’s performance. Due to the transparent nature of the device, the therapist is still able to provide manual guidance and cuing to the patient when needed.
The patient initiates all motion, while the Myomo device assists in providing accurate controlled assistance and feedback. With this capability, Myomo helps the patient reinforce movements within normal limits of the task, based on the expertise of the patient's treating therapist.
