Why does muscle weakness occur after a stroke and how can it be rehabilitated?
Muscle weakness after a stroke happens because the brain can't control muscles well anymore, and it can be improved with exercises and therapy.
Explanation
After a stroke, muscle weakness occurs because the brain, which controls the muscles, is damaged. This damage makes it hard for the brain to send signals to the muscles, causing them to become weak. Over time, the muscles can also shrink or lose strength because they are not used as much.
To help make the muscles stronger again, rehabilitation is important. This can include different exercises and therapies:
- Physical Therapy: Helps improve movement and strength with special exercises.
- Strength Training: Focuses on making muscles stronger through specific exercises.
- Routine Assessments: Regular checks can help measure how strong the muscles are getting.
These methods can help the muscles get stronger and work better over time. It's important to follow a plan made by healthcare professionals to get the best results.
