What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores whether the MyoPro, a device that aids arm movement, can improve arm function in individuals with incomplete spinal cord injuries. Participants will either train with the MyoPro or receive standard therapy with a brace for 12 weeks. Suitable candidates have had a spinal cord injury for at least a year, can move their shoulder slightly, and can follow directions during rehabilitation. As an unphased trial, this study provides participants the chance to contribute to groundbreaking research that could enhance rehabilitation options for spinal cord injuries.

Will I have to stop taking my current medications?

No, you will not have to stop taking your current medications. The trial requires that you continue taking all prescribed medication without any dosing changes.

What prior data suggests that the MyoPro device is safe for people with incomplete spinal cord injury?

Research has shown that the MyoPro device is generally safe for use. Studies have helped individuals with conditions like spinal cord injuries and strokes move their arms. Most users find it comfortable. However, like any medical device, some risks exist. Although studies do not detail specific side effects, the device is designed to assist without causing harm. Discussing any concerns with a healthcare provider before joining a trial is always advisable. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Unlike the standard treatments for spinal cord injury, which often involve conventional therapy and static braces, MyoPro offers an innovative approach by using a powered brace that assists with movement. This device is unique because it provides active support, enabling patients to engage their muscles during therapy, which can potentially enhance recovery. Researchers are excited about MyoPro because it could significantly improve motor function and independence for individuals with spinal cord injuries, offering more dynamic and interactive rehabilitation than traditional methods.

What evidence suggests that the MyoPro device is effective for improving upper extremity activities in people with incomplete spinal cord injury?

Research has shown that the MyoPro device, available to participants in this trial, can assist people with arm movement problems. Studies have found that this wearable device significantly reduces arm movement issues. Participants reported high satisfaction and noticed improved arm movement. Simply put, the device helps users move their arms more easily, offering hope for those with partial spinal cord injuries. It has also proven effective in similar situations, such as after a stroke, by enhancing arm mobility. ^{1 2 3 6 7}

A study on individuals with incomplete spinal cord injury (iSCI) showed that using a myoelectric powered wearable orthosis (UE-MPWO) for 6 weeks significantly improved handgrip active range of motion (AROM) and handgrip force.

The combination of in-clinic rehabilitation and at-home use of the UE-MPWO suggests it can effectively enhance upper extremity function, making it a promising rehabilitation tool for those with iSCI.

A study involving 12 participants with acute/sub-acute spinal cord injuries showed that using powered exoskeletons for locomotor training is generally safe, although symptomatic hypotension was the most common adverse event reported.

The feasibility of using exoskeletons was demonstrated, with 54% protocol compliance and 58% of participants achieving at least minimal assistance during walking sessions, indicating potential for effective rehabilitation in clinical settings.
