Trial results for a study evaluating EMG training for altering activation patterns after stroke were posted on ClinicalTrials.gov on 2026-03-20. The study observed a mean reduction of -7.5 minutes in timed test completion for participants undergoing unilateral EMG training.
Background
Stroke can lead to significant motor impairments, including muscle weakness and lack of coordination, particularly affecting hand function. Rehabilitation efforts often focus on improving these deficits to enhance daily living activities. This trial explored the potential of a new EMG-controlled game as an intervention to improve hand function in individuals living with chronic stroke.
Trial design
This completed study enrolled 20 participants. The trial investigated conditions including Stroke, Weakness, Muscle, and Coordination Lack. The intervention involved EMG training using a controlled game designed to improve hand function. Participants were assessed based on their performance in a timed test, with results reported for both bilateral and unilateral training approaches.
Key results
The study reported the following changes in mean completion time for a timed test:
- For the Bilateral training group, the mean change in completion time was -2.8 minutes, with a Standard Error of 2.2 minutes.
- For the Unilateral training group, the mean change in completion time was -7.5 minutes, with a Standard Error of 2.4 minutes.
These measurements indicate a reduction in the time taken to complete the test for both training approaches, with a more pronounced reduction observed in the unilateral training group.
What this means
The observed reductions in timed test completion suggest that EMG training, particularly when focused on unilateral movements, may contribute to improved hand function in chronic stroke survivors. While the data indicates a positive direction of effect, the small sample size of 20 participants and the absence of statistical analyses (such as p-values or confidence intervals) mean these findings should be interpreted with caution. Further research with larger cohorts and robust statistical evaluation would be necessary to confirm the efficacy and clinical significance of this intervention.
