Details and patient eligibility

About

The test subjects were selected from patients with clinical manifestations in muscle tone and healthy volunteers. Elbow flexor is the main target muscle. Fifty patients and 50 healthy subjects were given three assessment methods to measure muscle tension: modified Ashworth rating scale, elastic ultrasound technology and surface electromyography, and the data obtained by these three methods will be statistically analyzed and discussed.
