Hemiplegia due to stroke has increased. However, the use the ankle–foot orthoses (AFO) for hemiplegic patients is uncomfortable and their usability is not good. Therefore, in this study we analyzed the lower-body-joint angles of hemiplegic patients to determine the functional effectiveness of a new elastic-band-type AFO to prevent backward knee extension (back-knee) and foot drop (new product: NP) while walking.
Nine hemiplegic patients (eight males, and one female, 55.7 ±8.4 years, 165.8 ±9.2 cm, 68.8 ±11.5 kg, right hemiplegia: five patients, left hemiplegia: four patients, and average onset period: 6.6 years) were selected for participation in this experiment to capture gait motion using 12 cameras (MX-T20, Vicon, Inc.). Capturing gait motion was implemented under three conditions: without an AFO (without product: Wl), with the existing product made of a hard plastic material (existing product: EP), and using the NP.
The angle variation and maximum-minimum angle of lower-body joints were analyzed for the dorsi-plantar flexion of the ankle joint and flexion-extension of the knee joint. A one-way ANOVA test with Tukey’s-B post hoc multiple comparison was used to identify the existence or nonexistence of symptoms, and the statistically significant level for all statistical tests was set at p < 0.05.
For ankle-joint angle, the degree of plantar flexion with NP decreased. The angle variation also decreased (p < 0.05). Therefore, the effectiveness in the prevention of foot drop of NP was validated, and effectiveness of NP for the prevention of back-knee was also confirmed. The result also showed that knee-joint-angle variation decreased (p < 0.05). Nevertheless, the maximum degree of NP flexion was larger than the other products.
Herein, the effectiveness of NP in the prevention of foot drop and back-knee were validated through the analysis of lower-body-joint angles in the gait of hemiplegic patients. In the next study, we will suggest some optimization guidelines for patients wearing this new elastic-band-type AFO.
