A Passive Dynamic Ankle-foot Orthosis Approach to Enhanced Gait Function
نویسندگان
چکیده
Our keynote lecture will be given by Dr. Steven Stanhope, director of the Physical Disabilities Branch at the National Institutes of Health. Dr. Stanhope will discuss findings from a series of research projects related to customization and selective laser sintering construction of passive dynamic ankle-foot orthoses to meet a patient’s individual needs and the biomechanical basis for adapted compensatory movement control strategies will be explored.

Design of a quasi-passive 3 DOFs ankle-foot wearable rehabilitation orthosis.
Muscular rigidity and atrophy caused by long-term underactivity usually lead to foot drop, strephenopodia, foot extorsion or some other complications for the lower limb movement disorders or lower limb surgery sufferers. The ankle-foot orthosis can help patients conduct the right ankle motion mode training, inhibit spasm and prevent ankle complications. In this paper, a quasi-passive 3 DOFs ank...
متن کاملDesign and Evaluation of an Articulated Ankle Foot Orthosis with Plantarflexion Resistance on the Gait: a Case Series of 2 Patients with Hemiplegia
Ankle-foot orthoses (AFOs) have been described to have positive effects on the gait biomechanics in stroke patients. The plantarflexion resistance of an AFO is considered important for hemiplegic patients, but the evidence is still limited. The purpose of this case series was to design and evaluate the immediate effect of an articulated AFO on kinematics and kinetics of lower-limb joints in str...
متن کاملThe influence of passive-dynamic ankle-foot orthosis bending axis location on gait performance in individuals with lower-limb impairments.
BACKGROUND Passive-dynamic ankle-foot orthoses are commonly prescribed to augment impaired ankle muscle function, however their design and prescription are largely qualitative. One design includes a footplate and cuff, and flexible strut connecting the two. During gait, deflection occurs along the strut, with the greatest deflection at a central bending axis. The vertical location of the axis c...
متن کاملNon-velocity-related effects of a rigid double-stopped ankle-foot orthosis on gait and lower limb muscle activity of hemiparetic subjects with an equinovarus deformity.
BACKGROUND AND PURPOSE This study investigated the non-velocity-related effects of a 1-bar rigid ankle-foot orthosis on the gait of hemiparetic subjects, with particular emphasis on the muscle activity of the paretic lower limb. METHODS Twenty-one hemiparetic subjects who had been using an ankle-foot orthosis for equinovarus deformity for <1 week participated. Patients walked cued by a metron...
متن کاملThe effect of newly designed multi joint ankle foot orthosis on the gait and dynamic balance of stroke patients with foot drop
[Purpose] The purpose of this study is to investigate the effect of the newly designed multi joint ankle-foot orthosis on the gait and dynamic balance of stroke patients having foot drop. [Subjects and Methods] This study was conducted with 15 subjects who were diagnosed with stroke. 10-meter walk test, functional reaching test and timed up and go test were measured after each subjects wore a p...
