臨床上,大部分半身不遂的病人,使用踝前支架,一方面來矯正站立時足
部內翻的不正確姿勢,使其獲得正確的擺位,另一方面在走路時有更好的
步態。同時踝前支架的設計是針對台灣室內環境的需要,在室內可裸足行
走,不會滑倒。本篇研究利用步態分析來測量與評估八位半身癱瘓病人使
用及不使用踝前支架步態的差別。測量因子包括速度、步長、一步態週期
時間、步頻、步寬、單腳站立期、雙腳站立期及運動學(角度)包括髖關
節彎曲、伸直、外展、內縮,膝關節彎曲、外翻、內翻,踝關節背曲、蹠
曲。使用踝前支架比不使用踝前支架在量方面皆有改進但統計上無明顯的
差別,這可能是病人之間差異性太大及人數太少所致。

A new design of modified conventional type in orthosis usually
has its clinical indication.The anterior AFO with direct
molding meets the requirements of superior biomechanical
support and indoor barefoot walking in Taiwan. It could be
easily molded and modified for propor fitting of the foot.
Clinically, wearing the anterior AFO would be improving most of
the patients with the problem of inversion of the foot through
regaining correct alignment on the affected side during
standing and facilitating a better gait pattern during walking
. In this research study, the effect of anterior AFOs is
investigated by comparing eight chronic hemiplegia patients
with and without the anterior AFO. Gait characteristics are
also measured to determine statistically any difference between
with and without the AFO.The gait components include ty,
cadence ,stride time) and spatial characteristics(stride
length, step width),support time(single and double support
time) and kinematics (hip abd/add, hipflex/ext,knee varus/
valgus,knee flex/ext, ankle dor/plaflex) improved by AFO
fitting. The indicate that there is no significant difference
in any above parameters between the two groups. This is
probably due to the small sampling size and large variations of
the hemiplegic subjects. In order to determine the clinical
efficacy of anterior AFO,more patients is necessary for further
evaluation in the future.
