In patients with knee osteoarthritis, wearing a knee orthosis improves joint positioning. However, no attention has been paid to the wearing pressure, which indicates the tightness of the hook and loop fastener. The neurophysiological effects of local compression have been obtained by wearing the device. Therefore, increasing the wearing pressure may further improve the sense of joint positioning. In this study, we focused on the wearing pressure of the knee orthosis and examined its effect on joint position perception. The results showed that High Pressure was significantly lower in 60°of knee joint flexion than in Control (p<0.05). It was suggested that increasing the wearing pressure of the flexible knee orthosis may improve the sense of joint positioning.
Difference of gait pattern between with and without the robotic device is unknown while the efficacy of the gait-assistive robotic device has been reported occasionally. In the present study, kinematics and temporal-spatial characteristics during gait with the Honda Walking Assist was compared to without it. A female patient in her 70s had the grade D paraplegia in the ASIA impairment scale below T4 due to acute aortic dissection. While she was able to walk with a t-cane under the supervision, the compensatory movement was observed in the swing phase. The body-weight-supported gait on the treadmill with and without the Honda Walking Assist was performed. The gait cycles of the left leg was captured and analyzed with the motion analysis software (Kinovea). The results suggested that the gait training with the pattern close to normal and functional gait is available with the Honda Walking Assist.
