Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
In the conventional physical examination, modified Ashworth scale is used to evaluate spasticity, but its results may be influenced by temperature, joints range of motion, subjective judgement by tester or patient's nervousness. In the previous studies, spasticity between hemiplegic side and sound side showed significant difference in ratio of H/M amplitude, H/M threshold and H/M slope. Among them, H/M slope is the most sensitive tool and may be correlated to increased spasticity because H/M slope showed higher value in people with Brunnstrom stage III.
However, patients included in previous studies had disease onset over 2 years. The gold recovery stage after stroke is within 6 months. During this time, many methods can be used to reduce spasticity, such as medicine, stretching exercise, and injection. Therefore, it is very important whether H/M ratio for spasticity evaluation can be performed in patients with disease onset less than 2 years.
In our study, according to onset time, participants will be assigned to three groups: less than 6 months, 6 months to 2 years, and over 2 years. All the participants will accept electrophysiological test over four limbs to collect data of H/M ratio of slope, maximal amplitude and threshold. Hemiplegic side will be compared with sound side for significant difference. The relation between H/M ratio and modified Ashworth Scale will also be identified.
