Abstract EN
Quantitative evaluation of the hemiparesis status for a poststroke patient is still challenging.
This study aims to measure and investigate the dynamic muscle behavior in poststroke hemiparetic gait using ultrasonography.
Twelve hemiparetic patients walked on a treadmill, and EMG, joint angle, and ultrasonography were simultaneously recorded for the gastrocnemius medialis muscle.
Pennation angle was automatically extracted from ultrasonography using a tracking algorithm reported previously.
The characteristics of EMG, joint angle, and pennation angle in gait cycle were calculated for both (affected and unaffected) sides of lower limbs.
The results suggest that pennation angle could work as an important morphological index to continuous muscle contraction.
The change pattern of pennation angle between the affected and unaffected sides is different from that of EMG.
These findings indicate that morphological parameter extracted from ultrasonography can provide different information from that provided by EMG for hemiparetic gait.
