Overview
Brief Summary
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.

Outcomes
Primary Outcomes
shear wave elastography
Time Frame: through study completion, an average of 1 year
use shear wave elastography to evaluate Young's modules of target muscles at each angle of the joint during the passive movement
surface electromyography
Time Frame: through study completion, an average of 1 year
use surface electromyography to evaluate average EMG, integrated electromyogram and root mean square of the target muscles
Modified Ashworth Scale
Time Frame: through study completion, an average of 1 year
Modified Ashworth Scale of the target muscles
