可変粘性継手を有する短下肢装具による歩行実験(J05-2 ライフサポート(2),J05 ライフサポート) [in Japanese] Gait analysis with an Ankle Foot Orthosis with Variable Viscosity Joint [in Japanese]
Access this Article
Ankle-foot orthosis (AFO) is a primal aid for patients with gait disorder. Mechanical characteristics of AFO joint directly affect the walking function, and the viscoelasticity of AFO joint might be changed during gait, at least for stance/swing phases respectively. In this article, we designed an AFO joint with MR-fluid so that the viscosity alternated in accordance with the shank angular velocity. We observed the gait with the prototyped AFO of a hemiplegic patient using a shoehorn type AFO in his daily life. It was shown that the shank angular velocity remarkably reduced at the period of heel contact to foot flat, and that the ankle plantar flexion pattern at the initial stance phase becomes more similar to that of people without disability than with his own AFO.
