| Summary: | 碩士 === 國立陽明大學 === 復健科技輔具研究所 === 92 === Objectives: The purpose of this study was to compare lower extremity joint kinematics and kinetics during level walking with and without a functional knee brace in stroke patients with knee hyperextension.
Design: VICON370 Motion analysis systems were collected kinematics data and synchronize collected kinetics data with AMTI 3-dimentational force platform system, 12 hemipelgia subjects were including our study.
Setting: A gait laboratory.
Main Outcome Measures: Step width, step length, cycle time and ROM over lower limb kinematics variables and max hip, knee, and ankle joint moment kinetics variables during level walking.
Results: Step width, sound side stride length, affective side stride length, sound side hip flexion-extension, hip abduction-adduction, knee flexion-extension and affective side hip flexion-extension, knee flexion-extension, and ankle plantarflexion-dorsiflexion were significant difference (p, < 0.05). The kinetics variables were significant difference over affective lower extremity including Max hip extensor moment, hip external rotator moment, knee abductor moment, knee extensor moment, knee external rotator moment, knee flexor moment, ankle eversion moment, ankle plantarflexor moment and ankle dorsiflexor moment (p, < 0.05)..
Conclusion: Stoke patients with knee hyperextension applying functional knee brace may lead the more step width, step length and less ROM over sound and affective lower extremity and required less hip flexor, knee flexor, knee extensor, ankle dorsiflexor, but required more ankle plantarflexor moment.
