Does the device use Electrical Stimulation?
No, there is no electrical stimulation involved. The device uses a patented technology using a non-invasive skin sensor to detect a user’s own muscle signal then uses their myoelectric signals to power the device and move if the patient initiates a muscle contraction.
Can a patient use the device if they have a pacemaker?
Does this restore movement to the hand?
Currently, the mPower is worn on the arm to restore elbow movement. Look for a Myomo hand product at some point in the future.
What about the shoulder?
The mPower is worn on the arm to restore elbow movement. It is important for patients to implement a good shoulder exercise/strengthening program with their therapist while working with the Myomo mPower.
What about spasticity?
Patients with moderate spasticity can still use the device. Depending on the mode and setting from the software, patients can benefit from learning how to actively use the muscle and shut off the muscle via biofeedback. Severe tone that prevents a user’s arm from being ranged out by a clinician is a contraindication.
What about patients who are flaccid?
Patients must have at least trace muscle signal to be a candidate for the device (Manual Muscle Test of 1). With a consistent training regimen a patient with a flaccid arm may potentially gain improved range of motion using device. Results will vary for every patient.
Who is a candidate?
• Trace muscle signal in bicep and/or tricep
• Full passive Range of Motion at the elbow
• Able to follow simple 3-step commands
• Patients with tone may use the device
• There is no electrical stimulation, so pacemakers are not a problem
Who isn’t a candidate for the device (contraindications)?
• Shoulder dislocation (Subluxation is ok but needs to be assessed by a therapist)
• Inability to support 1 ½ pounds of weight with the affected arm
• Contracture at elbow or Modified Ashworth score of 4
• Inability to follow simple, 3-step commands
Do you need surgery to use the Myomo device?
No, surgery is not required. The device is completely non-invasive. Movement of the orthosis is controlled through an electrical signal that is sent from the muscle via a sensor placed on the surface of the skin. There is no electrical signal sent into the body.
Can the device be used on patients getting injections to treat spasticity?
Yes. It is easy to re-program the device to allow for changes in spasticity levels due to medications or improvements from therapy. The device also re-calibrates each time you use it. As long as there is still a trace muscle contraction present, you will be able to control the orthosis.
