A Portable Ankle-Foot Rehabilitation Orthosis Powered by Electric Motor
Powered ankle-foot orthosis can not only prevent foot-drop and assist patients’ walking but also improve the ankle joint movement for patients with dysfunction caused by the various injuries and nervous system diseases. Common ankle rehabilitation devices limit the ankle injury patients’ rehabilitation training within fixed places, so a portable powered ankle-foot orthosis is presented in this ...
متن کاملA portable powered ankle-foot orthosis for rehabilitation.
Innovative technological advancements in the field of orthotics, such as portable powered orthotic systems, could create new treatment modalities to improve the functional out come of rehabilitation. In this article, we present a novel portable powered ankle-foot orthosis (PPAFO) to provide untethered assistance during gait. The PPAFO provides both plantar flexor and dorsiflexor torque assistan...
متن کاملActuation Timing Strategies for a Portable Powered Ankle Foot Orthosis
Ankle-foot orthoses (AFOs) are used to assist persons with lower-limb neuromuscular impairments. We have developed the portable powered AFO (PPAFO). This device uses a bidirectional pneumatic actuator powered by a CO2 bottle to provide dorsiflexor and plantarflexor torque assistance. The PPAFO operates tether-free, allowing for use outside of the laboratory. This system has been tested on one i...
متن کاملAn 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 کاملSimulation and Experimental Analysis of a Portable Powered Ankle-Foot Orthosis Control
A portable powered ankle-foot orthosis (PPAFO) was previously developed using off-the-shelf pneumatic components to explore new opportunities for fluid power in human assist devices. The untethered pneumatically powered ankle-foot orthosis provides both motion control and torque assistance at the ankle via a binary, event-based control scheme that uses solenoid valves. While stable, the binary ...
