FAQs for Clinicians:
What is the MyoPro’s Intended Use?
The MyoPro, an upper limb orthosis, is a compensatory device to increase the ability to perform functional tasks with the affected limb. The user voluntarily activates movement of the orthotic device with their remaining electromyography (EMG) muscle signal.
What is the MyoPro’s Indication for Use?
The MyoPro is indicated for use by adolescents (ages 12+), adults (ages 18+), veterans, diagnosed with long-term muscle weakness OR partial paralysis.
What are the MyoPro’s Contraindications?
The MyoPro is contraindicated for use as follows:
- Insufficient myoelectric signal output from at least one muscle group needed to activate the desired powered joint (for example, biceps or triceps signal to extend the affected elbow).
- Severe shoulder subluxation.
- Excessive pain in shoulder, arm or hand during facilitated range of motion.
- Contraindicated during recovery from acute injury such as trauma, infection, or skin condition.
- Upper extremity contracture(s) that prevent functional movement to benefit from the orthosis.
- Rigid spasticity in the affected muscle groups.
- Arm circumferences and lengths that are outside build specifications required to be fit with the orthosis.
- Cognitive or behavioral impairment that would inhibit safe use of the orthosis.
- Other medical issue which interferes with safe use of the device for functional improvement.
Is the MyoPro covered by medical insurance?
MyoPro is covered by most insurance companies and the U.S. Veterans Administration.
Currently, purchase of MyoPro is not covered by Medicare, but we have applied for coverage and expect to have news on this in 2019.
What is the research behind the MyoPro technology?
Myomo is committed to research and continues to grow the body of medical evidence which supports the use of this technology. At present, we have published research with The Ohio State University and others, and ongoing research with the U.S. Veterans Administration. Please visit our Scientific Evidence page at www.myomo.com for more information. Additional documentation on MyoPro & electromyography (EMG) related research is available upon request.
Is Myomo’s technology similar to electrical stimulation?
No. The MyoPro does NOT stimulate a User’s muscles with an external electrical impulse. This orthosis uses passive sensors on the surface of the skin to detect electrical signal within a muscle (electromyography).
Models and Product Information
What MyoPro models are available?
There are three distinct MyoPro models with powered joint(s). The joint(s) are myoelectrically controlled by the wearer’s own muscle signal.
- MyoPro Motion E: An elbow-wrist orthosis with a powered elbow, and static, rigid wrist support.
- MyoPro Motion W: An elbow-wrist orthosis with a powered elbow and a multi-articulating wrist (MAW) with flexion/extension and supination/pronation. The passive MAW may be prepositioned by the user to increase task-specific function.
- MyoPro Motion G: An elbow-wrist-hand orthosis with a powered elbow, passively adjustable multi-articulating wrist (MAW), and a powered, 3-jaw-chuck grasp.
Is the MyoPro custom made for each patient?
Each MyoPro brace is custom fabricated to each patient for optimum comfort and performance. During the fitting process, a fiberglass molding of the patient's arm will be taken. This mold is sent off to a central fabrication facility for custom MyoPro construction. The individual being fitted may be presented with a variety of MyoPro colors and patterns to choose from.
What is new about the MyoPro?
- Battery: Interchangeable battery; Users can replace a drained battery for a charge one while wearing the device. 4+ hours of continuous use on one battery.
- User Interface: Graphical labeling of control buttons. Repositioned to the anterior of the arm for clearer visibility to the User while wearing the device.
- Sensors: Electrical and mechanical redesign for improved performance.
- Electronics: Streamlined electronics circuitry for improved reliability.
- Harness: Increased structure to the shoulder saddle for product longevity. Lower profile design for aesthetic and comfort.
- Finger Orthosis for the Motion G: Easier to put on. More secure latching mechanism. Improved robustness of materials.
What is the MyoPro warranty?
All MyoPro hardware & electronics, battery charger, and carrying bag are covered by a 3-Year Warranty. Orthosis soft goods (pads, straps, and harness), and the battery are covered by a 1-Year Warranty. After the warranty period has passed on a particular item, a User & Provider can resubmit to insurance for replacement. The warranty period on the item would then restart at the date of shipment to the Provider.
How much can a MyoPro’s elbow lift?
The MyoPro’s elbow motor offers approximately 7 Newton-meters of torque. A torque value divided by a distance value calculates a force value. Since each MyoPro User’s forearm and hand will be a different length, the amount of lift force should be calculated individually for each User. The amount of assist also depends on how much strength (if any) the User has in his/her biceps, and the weight of the User’s arm.
For example: an adult female in the 50th percentile would have a forearm and hand length that would sum to approximately 17 inches (0.43 meters).
How much can the MyoPro Motion G’s hand hold (pinch force)?
The grasp motor offers approximately 1.1 Newton-meters of torque. Torque divided by a distance calculates a force. Since each MyoPro User’s hand will be a different size, the amount of pinch force at the fingertip of the User should be calculated individually for each User. The assist also depends on how much strength (if any) the User has in his/her wrist flexors.
For example: an adult male in the 50th percentile would have an index finger length of approximately 4 inches (0.1 meters); 1.1 Newton-meters divided by 0.1 meters equals 11 Newtons (2.5 pounds) of pinching force.
I see that the MyoPro Motion G’s finger orthosis only connects the first and second finger to the hand motor – why aren’t all 4 fingers connect?
The common, 3-Jaw Chuck grasp pattern, we believe, provides Users with a combination of smaller pinch and larger grasp functional capability for Myomo’s first assistive grasp development.
For users with wrist tone, we have seen them face greater challenge to control muscle activation and relaxation within their forearm when all 4 fingers are part of the grasp pattern.
Does a MyoPro use dry electrodes or wet electrodes?
The sensors for a MyoPro are dry; there is no adhesive or gel needed for use.
Therapy and Training:
What is needed to program a MyoPro?
The MyoPro is programmed with a software program called MyConfig. The software is compatible with Windows operating systems from Windows 7 and above. It connects to the MyoPro via a Bluetooth wireless connection. All MyoPro’s come with a laptop computer equipped with MyConfig. The software can also be installed on other clinical computers. Myomo is happy to work with your facilities’ IT department to organize the software installation if necessary.
Should MyoPro patients plan to see a physical therapist after getting the brace configured?
It is recommended that all new MyoPro users attend occupational therapy to develop proficiency and independence with their MyoPro. Once a therapist is trained on the MyoPro system, they can assist the user by developing a customized treatment plan that will maximize their functionality and overall success. Therapy with a MyoPro can include functional task practice, improving muscle control and coordination, learning how to put on/take off the MyoPro and how to care for it at home.
How does a clinician begin working with a potential MyoPro user?
A potential MyoPro user may be referred by a physician or therapist, or the O&P practitioner may already have a patient he/she is working with. The first step is to speak with a Myomo representative for guidance. A thorough evaluation is essential for a successful outcome and Myomo provides the necessary training and resources throughout the process.
What training is available to O&P practitioners and Therapists?
Training is required for clinicians to provide a MyoPro. The Myomo clinical support team provides remote and in-person training sessions to O&P clinicians and Occupational Therapists as appropriate for evaluation, casting, fitting, therapy, and user follow-up.
How much therapy is required, or what therapy is recommended?
As therapy is essential for an optimal outcome, Myomo recommends new MyoPro users work with a trained therapist to ensure a progressive therapy, specific to the user’s needs and goals. Therapy varies as each individual will progress differently and users often may need two months or more of therapy.
