The Myomo MyoPro is a myoelectric robotic arm orthosis that enables a person with a weak or partially paralyzed arm to perform activities of daily living, such as feeding, reaching, and lifting. The MyoPro monitors and senses — but does not stimulate — the affected muscles, allowing the user to initiate and control movements using his or her own muscle signals.
The MyoPro uses electromyography (EMG) control software to continuously monitor and sense even very weak muscle signals. When the user initiates a movement, sensors in the brace detect the muscle signals and then assist the person to move the elbow based on the settings the therapist has set up for the person. This processing occurs so quickly that it is not apparent to the person wearing the device.
The MyoPro is used to by a broad range of people with muscle weakness and neuromuscular damage from conditions such as:
- Brachial plexus injury
- Spinal cord injury
- Multiple sclerosis
- Traumatic brain injury
- Amyotrophic lateral sclerosis (ALS
- Cerebral palsy
- Brain tumors
- Guillain-Barré syndrome
You may be a good candidate for the MyoPro if you have limited mobility or long-term muscle weakness in an arm due to a neurological disorder or another condition.
You are not a good candidate if you have any of the following:
- Elbow contractures that limit function
- Shoulder dislocation
- Severe pain or abrasions
- Spasticity that makes you unable to extend your arm at the elbow
- Decreased skin integrity
- Not able to follow simple verbal commands
You must have trace muscle movement to use the MyoPro.
