Summary

This study compares two ways of using a robotic device to help people with chronic stroke regain arm function. About 72 participants will receive 18 sessions of robotic training over 6 weeks, either starting with the forearm or the wrist. Researchers will measure arm movement, strength, and coordination before, after, and 3 months later to see which approach works better.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance: Bi-Manu-Track robotic device
What this could lead to: If successful, this could identify the best order of robotic arm exercises to improve recovery after stroke.
What could go wrong: This is a small, early-stage study with no control group. Results may not apply to all stroke survivors, and the benefit may be modest.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * The inclusion criteria are age between 20 and 75 years old, more than 3 months after the onset of a first unilateral ischemic or hemorrhagic stroke, moderate to severe UE motor impairment (i.e., total UE score of the Fugl-Meyer Assessment \[FMA\] score between 18 and 56), no severe spasticity in any joints of the affected arm (modified Ashworth Scale score \<3 in any of the affected shoulder, elbow, wrist, and fingers), able to follow instructions (Mini-Mental State Examination total score \>24), no UE fractures in the past 3 months, and not simultaneously participating in other medication or rehabilitation studies. Exclusion Criteria: * The exclusion criteria are other neurologic, neuromuscular, or orthopedic disease, such as epilepsy, or severe health or physical conditions that might impede participation in this study.
