An ankle-foot orthosis powered by artificial pneumatic muscles.
We developed a pneumatically powered orthosis for the human ankle joint. The orthosis consisted of a carbon fiber shell, hinge joint, and two artificial pneumatic muscles. One artificial pneumatic muscle provided plantar flexion torque and the second one provided dorsiflexion torque. Computer software adjusted air pressure in each artificial muscle independently so that artificial muscle force ...
متن کاملMechanical performance of artificial pneumatic muscles to power an ankle-foot orthosis.
We developed a powered ankle-foot orthosis that uses artificial pneumatic muscles to produce active plantar flexor torque. The purpose of this study was to quantify the mechanical performance of the orthosis during human walking. Three subjects walked at a range of speeds wearing ankle-foot orthoses with either one or two artificial muscles working in parallel. The orthosis produced similar tot...
متن کاملEffect of ankle-foot orthosis (AFO) on body sway and walking capacity of hemiparetic stroke patients.
Body sway, the total length of the sway of the center of foot pressure (CFP) and maximum walking speed were examined with and without AFO in eight post-stroke hemiparetic patients. Without AFO, the CFP moved towards the non-affected limb and the body sway was large. Wearing AFO, the CFP shifted to the midposition and the body sway became small. Without AFO, the time to walk the prescribed dista...
متن کاملApplication of the Superelastic NiTi Spring in Ankle Foot Orthosis (AFO) to Create Normal Ankle Joint Behavior
Hinge-based Ankle Foot Orthosis (HAFO) is one of the most common non-surgical solutions for the foot drop. In conventional HAFOs, the ankle joint is almost locked, and plantar flexion is restricted due to the high stiffness of the hinge mechanism. This often leads to a rigid walking gate cycle, poor muscle activity, and muscle atrophy. Since the ankle torque-angle loop has a non-linear profile,...
متن کاملDevelopment of an ankle-foot orthosis with an oil damper.
The purpose of the present study was to develop an ankle-foot orthosis (AFO) that satisfies the requirements for an AFO for patients with hemiplegia as determined in a previous study. An oil damper has been introduced as an assistive device. The oil damper provides a resistive moment to plantar flexion of the ankle joint during initial stance on the paretic side. This function improves the insu...
