Abstract
ABSTRACT: The purpose of this case series was to
explore the impact of a novel design for an ankle-foot orthosis (AFO) on
gait and balance in persons with post-stroke hemiparesis. Five subjects
with hemiparesis after cerebrovascular accident were referred for
evaluation for an AFO because of gait and balance impairments. All
subjects were found to have difficulty in both the swing and stance
phases of gait, exhibiting difficulty with swing limb clearance and
stance limb stability. The advanced ground reaction design of AFO
(A-GRAFO) was chosen as the most appropriate device for orthotic
management. The specific orthotic design used in this study was a
Dynamic Bracing Solutions Balancer™. Advanced triplanar control of the
limb was achieved through the use of a unique segmented weight-bearing
impression technique, specific cast modifications, specific alignment
parameters, intimate fit, and rigid materials. Gait speed, gait
endurance, and balance were assessed for each subject using the 10-m
walk test, 6-minute walk test, and Timed Up and Go Test (TUG) before and
after receiving the A-GRAFO. All subjects improved in gait speed and
gait endurance, whereas four of the five improved in balance. Gait speed
increased an average of 0.30 m/second (55%), 6-minute walk distance
increased an average of 96 m (52%), and time to complete the TUG
decreased by 5 seconds (24%) for subjects using the A-GRAFO compared
with the no-orthosis condition. The results of this case series suggest
that this orthosis design should be considered for patients with
residual hemiparesis after stroke. Further research is warranted to
compare the A-GRAFO against more traditional designs.
Interestng, Dean. My TUG test dropped from 12 seconds to 6 after getting my Bioness L300.
