GAIT POSTURE , 2006, vol. 23, n° 4, p. 425-428 Doc n°: 125421 Localisation : Documentation IRR Descripteurs : EC25 -ORTHESES DE MEMBRE INFERIEUR We constructed a powered ankle-foot orthosis for human walking with a novel myoelectric controller. The orthosis included a carbon fiber and polypropylene shell, a metal hinge joint, and two artificial pneumatic muscles. Soleus electromyography (EMG) activated the artificial plantar flexor and inhibited the artificial dorsiflexor. Tibialis anterior EMG activated the artificial dorsiflexor. We collected kinematic, kinetic, and electromyographic data for a naive healthy subject walking with the orthosis. The current design improves upon a previous prototype by being easier to don and doff and simpler to use. Langue : ANGLAIS |
