Assessing muscle spasticity in stroke patients using movement analysis
Assessment of Upper Extremity Muscle Spasticity and Impedance Using the Movement and Electromyographical Analyses
This study is testing how muscle activity and stiffness in the arms of stroke patients compare to healthy adults during hand movements to better understand muscle function after a stroke.

What this trial studies
This observational study aims to objectively measure muscle activity and spasticity in stroke patients and healthy adults through the use of a dynamometer and surface electromyography during hand circular motion activities. It will establish a database of upper limb muscle activity parameters and test the reliability of muscle testing methods. The study will also compare electromyographic signals and muscle strength between stroke patients and healthy individuals, exploring the relationships between these measurements and existing muscle spasm classifications.
Who should consider this trial
Good fit: Ideal candidates for this study are adults aged 20 to 65 who have been clinically diagnosed with stroke and have a Mini-Mental State Examination score of 25 or higher.
Not a fit: Patients with recent shoulder, elbow, or wrist joint issues, or those with significant muscle or nerve disorders may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved assessment methods for muscle spasticity in stroke patients, enhancing rehabilitation strategies.
How similar studies have performed: Other studies have shown success in using electromyography and movement analysis for assessing muscle spasticity, indicating that this approach is supported by existing research.
