Experimental and computational analysis of composite ankle-foot orthosis.
Carbon fiber (CF) ankle-foot orthoses (AFOs) can improve gait by increasing ankle plantar-flexor power and improving plantar-flexor ankle joint moment and energy efficiency compared with posterior leaf spring AFOs made of thermoplastic. However, fabricating a CF AFO to optimize the performance of the individual user may require multiple AFOs and expensive fabrication costs. Finite element analy...
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 ...
متن کاملNewly designed computer controlled knee-ankle-foot orthosis (Intelligent Orthosis).
The authors have developed a knee-ankle-foot orthosis with a joint unit that controls knee movements using a microcomputer (Intelligent Orthosis). The Intelligent Orthosis was applied to normal subjects and patients, and gait analysis was performed. In the gait cycle, the ratio of the stance phase to the swing phase was less in gait with the knee locked using a knee-ankle-foot orthosis than in ...
متن کاملUse of bivalved ankle-foot orthosis in neuropathic foot and ankle lesions.
The neuropathic foot is a common complication of diabetes mellitus and is associated with development of chronic ulcers and Charcot joints. Treatment of these complications presents a complex management task. This report presents long-term follow-up data on 16 patients with neuropathic changes who were treated with a total contact, laminated, bivalved, rocker-bottom-soled ankle-foot orthosis (T...
متن کاملEnergy expenditure in stroke subjects walking with a carbon composite ankle foot orthosis.
OBJECTIVE To measure walking speed and energy cost in patients with prior stroke with and without a carbon composite ankle foot orthosis. DESIGN Within-group comparisons of 2 walking conditions. PARTICIPANTS Convenience sample of 10 hemiparetic patients with a stroke at least 6 months earlier (average age 52 years) habituated to a carbon composite ankle foot orthosis. METHODS Subjects wal...
