Wearable MCI for Arm Movement After Stroke

This study is testing a wearable device called a myoelectric-computer interface (MCI) to help improve arm movement in people who have had a stroke. The MCI aims to reduce abnormal muscle co-activation (when muscles work against each other) by giving feedback about individual muscle activity. You might be able to join if you've had a stroke that caused arm weakness, either recently (within 21 days) or at least 6 months ago, and have severe motor impairment. The main goal is to see how well the MCI improves arm function, measured by the Wolf Motor Function Test, over 6 weeks. The study is currently recruiting 96 participants.

Study design
This is a randomized, controlled, and blinded study, meaning participants are randomly assigned to receive either the MCI or a sham (inactive) version, and neither you nor the researchers will know which you are receiving. It plans to enroll 96 participants.
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
Your arm function will be measured at the beginning of the study and again at 6 weeks.
