Welcome back to the ORIEMS FIT Research Digest, where we simplify groundbreaking research to make it accessible for everyone.
Today, we explore a fascinating study from the USA that shows how Electrical Muscle Stimulation (EMS) is helping scientists understand muscle recovery in adults recovering from strokes.

Letโs dive in and see how this research might inspire new ideas for fitness and recovery.
What is this research about?
The study, titled "Effects of Intensive Physical Rehabilitation on Neuromuscular Adaptations in Adults with Poststroke Hemiparesis," investigated how intensive rehabilitation affects muscle strength and neuromuscular adaptations in people recovering from strokes.
EMS was used as part of the study to measure muscle properties, giving researchers deeper insights into muscle activity.
Who conducted this research and where?
- Authors: R.J. Gregory, J.E. Dixon, S.L. Barker, and colleagues.
- Institution: This research was conducted at Arizona State University, a leading institution for biomedical and health-related research.
- Country: United States of America.
- Funding: Supported by grants from the National Institutes of Health (NIH), underscoring the studyโs credibility.
Who participated in the study?
The study involved 18 adults aged 50โ75 years who had experienced a stroke, leading to poststroke hemiparesis (muscle weakness on one side of the body).
These individuals had varying degrees of motor function impairments, providing a diverse dataset for analysis.
What did the researchers measure?
The researchers focused on:
- Muscle Strength: Evaluated using traditional strength tests.
- Neuromuscular Properties: Measured using EMS, which helped determine how well muscles responded to electrical signals.
- Walking Ability: Tested before and after a 12-week intensive rehabilitation program.
What did they find?
General Explanation
The study found that intensive rehabilitation improved muscle strength and walking ability in participants.
EMS, though primarily used for measurement, provided unique insights into how muscles responded to training after a stroke.
Specific Evidence Supporting EMS
-
Measuring Muscle Response:
- EMS was used to assess muscle excitability and activation levels during the rehabilitation process. This helped identify which muscles were improving and how effectively the nervous system was reconnecting with muscles.
-
Tracking Progress:
- Over 12 weeks, EMS measurements showed a 15% improvement in muscle responsiveness on the affected side, correlating with gains in strength and mobility.
-
Rehabilitation Insights:
- EMS revealed that even when participants couldnโt feel full control over their muscles, the muscles themselves were becoming more reactive to signalsโa promising sign for long-term recovery.
Why does this matter?
This research highlights the role of EMS as a diagnostic tool to:
- Monitor recovery progress in people with muscle impairments.
- Identify areas needing more targeted rehabilitation.
- Provide insights that could shape future therapies for stroke recovery.
How can this help EMS device users?
While this study focused on poststroke rehabilitation, it shows the potential for EMS to:
- Help track muscle responsiveness during recovery from injuries.
- Support training programs by identifying underactive muscles.
- Offer a tool for understanding how the nervous system interacts with muscles after periods of inactivity.
