Abstract

<p>Knee-ankle-foot orthoses (KAFOs) are prescribed for stroke hemiplegic patients with unstable lower limbs. To date, however, no research has compared and verified the effect of the differences in ankle joint function on kinematics and muscle activity during gait in post-stroke patients using KAFOs. To determine the effect of KAFOs with different ankle joint settings—plantar flexion stop (KAFO-PS), and plantar flexion resistance (KAFO-PR)—on the gait of stroke patients in the subacute phase, the gait of 7 stroke patients using KAFOs with ankle joint settings—KAFO-PS and KAFO-PR—was assessed using surface electromyography (EMG) and an electrogoniometer, a three-axis gyro sensor. The ankle plantar flexion angle during loading response and the muscle activity ratio of the tibialis anterior in loading response, hip extension angle change during anterior swing were significantly larger with KAFO-PR compared with KAFO-PS. It was suggested that the difference in plantar flexion function of the ankle joint of KAFOs affects the kinematics and muscle activity of the ankle and hip joints during gait.</p>
