Comparison of Gait Analysis Between Anterior and Posterior Ankle Foot Orthosis in Hemiplegic Patients

Abstract

Wearing anterior ankle foot orthosis was as useful as posterior ankle foot orthosis for correcting hemiplegic gait.

Effects of an ankle-foot orthosis with oil damper on muscle activity in adults after stroke

“…An ankle-foot orthosis (AFO) can improve the gait of hemiplegic individuals [12,13]; however, the limited ankle motion associated with an AFO with plantarflexion stop [14,15], AFO with bilateral stop [13], or unarticulated AFO [16], seems to be disadvantageous for ankle function, because both heel and forefoot rocker functions require adequate plantarflexion range. An AFO with an oil damper (AFO-OD) was developed to assist the heel rocker function [17,18]; however, differences between an AFO-OD and an AFO with limited motion are not clear.…”

Long-Term Effect of an Anterior Ankle-Foot Orthosis on Functional Walking Ability of Chronic Stroke Patients

“…Wong et al 13 and Park et al 10 observed no significant difference between the A-AFO and P-AFO in increasing walking speed, stride strength, and velocity. Sheffler et al 34 found that stroke patients with the P-AFOs improved significantly (relative to no device) in the floor, the carpet, and the Bup and go[ tasks and a trend toward significantly in the obstacle and stair tasks of mEFAP.…”

“…4Y8 Because of hot weather, people in some Asian countries used to walk with bare feet indoors, and P-AFO is not suitable under such conditions. 9,10 In Taiwan, a low-temperature customized molded plastic anterior AFO (A-AFO) ( Fig. 1), which could be worn barefoot indoors as well as with shoes, is the principal orthotic intervention for residual ankle weakness poststroke.…”

“…9,11Y14 Despite its widespread usage, only three studies searching for the ambulationrelated effect have been conducted thus far. 10,13,14 All these studies focused on gait analysis, which represented the level of body function only. Walking has been identified as one of the most important components of activity and participation domains 1 ; ambulation assessment should include variables in the patients_ daily living environment.…”

Valid and Reliable Instruments for the Clinical Assessment of the Effect of an Ankle-Foot Orthoses on Balance

“…15 Anterior and posterior AFOs were compared in persons with hemiplegia, and the BBS scores did not differ significantly for any condition (barefoot, anterior AFO, or posterior AFO), although gait measures did differ significantly between the barefoot and AFO conditions. 16 It is also important to note that the average BBS in this study was 37.3, meaning that the average subject was at the upper end of the medium fall risk category. Simons et al 17 found that AFOs did significantly improve BBS score, when compared with no AFO, in stroke survivors.…”
