Abstract Background: It has been reported the effects of a hinged ankle-foot orthosis on the gait ability of children with cerebral palsy. However, no studies investigated the effects of the dorsiflexion angle of the hinged ankle-foot orthosis on the spatiotemporal gait parameters of children with cerebral palsy. This study aimed to investigate the immediate effects of a 10° dorsiflexion inducing ankle-foot orthosis the spatiotemporal gait parameters of children with spastic diplegia compared to barefoot and a hinged ankle-foot orthosis.Methods: This study was cross-over design. 10 children with spastic diplegia were walked with barefoot, a hinged ankle-foot orthosis, and a 10° dorsiflexion inducing ankle-foot orthosis. GAITRite was used to collect the spatiotemporal gait parameters including gait velocity, cadence, step length, stride length, single leg support, and double leg support. Results: It showed that a 10° dorsiflexion inducing ankle-foot orthosis significantly improved the gait velocity, cadence, step length, stride length, single leg support, and double leg support than barefoot and a hinged ankle-foot orthosis (p<.05). Conclusion: The results of this study implied that a 10° dorsiflexion inducing ankle-foot orthosis could improve the gait ability of children with spastic diplegia more than barefoot or a hinged ankle-foot orthosis. High quality future studies will need to examine the effects of hinged ankle-foot orthosis on gait ability according to dorsiflexion angles.

Background:There are a wide variety of ankle foot orthoses used in clinical practice which are characterised by their design, the material used and the stiffness of that material. Changing any of these three components will alter the effect of the ankle foot orthosis on gait.Objectives:The purpose of this article is to provide an overview on the available research on ankle foot orthosis–footwear combination tuning on the gait characteristics of children with cerebral palsy through a structured review.Study Design:Literature review.Methods:A thorough search of previous studies published in English was conducted within all major databases using relevant phrases without any limits for the dates. These searches were then supplemented by tracking all key references from the appropriate articles identified including hand searching of published books where relevant.Results:To date, there are 947 papers in the literature pertaining to the study of ankle foot orthosis. Of these, 153 investigated the use of ankle foot orthosis for children with cerebral palsy. All the studies included in this review were of a within-subjects design and the evidence levels were generally low.Conclusions:The overall results suggested that ankle foot orthosis–footwear combination tuning has the potential to improve the kinematics and kinetics of gait in children with cerebral palsy. However, the review highlights a lack of well-designed and adequately powered studies.Clinical relevanceWhile the research described in this article indicates an improvement in the gait of children with cerebral palsy following tuning of their ankle foot orthosis–footwear combination, there is still a paucity of research with quantitative data on the effects of kinematics and kinetics of ankle foot orthosis–footwear combination tuning, comparing untuned ankle foot orthosis–footwear combinations with tuned ankle foot orthosis–footwear combination. Furthermore, current research does not identify the effect of tuning on energy efficiency.

Background: An ankle-foot orthosis with an oil damper was previously developed to assist the first rocker function during gait, but the effects of the amount of resistive moment generated on gait have not been clarified. Objectives: To measure the amount of resistive moment generated by the ankle-foot orthosis with an oil damper during gait and determine its effect on the gait of patients with stroke. Study Design: Preliminary cross-sectional study. Methods: The gait of four patients with stroke in the chronic phase was measured in four conditions: without an ankle-foot orthosis and with the ankle-foot orthosis with an oil damper generating three different amounts of resistive moment. Measurements were taken with a three-dimensional motion analysis system and a specially designed device to determine the resistive moment. Results: The resistive moment was observed in the former half in stance of the paretic limb, and its magnitude was less than 10 N m. Some gait parameters related to terminal stance and preswing were affected by the amount of resistive moment. The forward component of floor reaction force and the shank vertical angle showed peak values when the patients reported feeling most comfortable during gait. Conclusion: Although the resistive moment generated by the ankle-foot orthosis with an oil damper was small, it was sufficient to alter gait. Clinical relevance To maximize the effectiveness of ankle-foot orthoses, it is necessary to know the effects of resistive moment on the gait of patients with stroke. The ankle-foot orthosis with an oil damper assists the first rocker function in gait and also affects the gait in a later phase in stance. The peak values of some gait parameters coincided with patients reporting gait to be most comfortable. It is important to know that ankle-foot orthosis with an oil damper assistance in the first rocker alters the weight acceptance on the paretic limb and affects the gait parameters related to propulsion ability in stance.

Background: One of the important goals in the treatment of spastic cerebral palsy is to maintain efficient and effective walking in order to be independent in activities and participate in society. Objective: To compare the efficacy of foot combination taping of kinesio tape and athletic tape vs ankle foot orthosis in correcting spatiotemporal gait parameters in children with spastic diplegia. Methods: Thirty-six children with spastic diplegia were randomly assigned into 3 groups; control, combination taping, and ankle foot orthosis groups. Children in the control group, in addition to those in both experimental groups, continued with conventional physical therapy, 1 h, 3 times per week for 4 weeks. Spatiotemporal gait parameters were assessed with the GAITRite system before and after the application of interventions. Results: Significant increases in walking velocity, step length, stride length, right single support duration, and left single support duration of the ankle foot orthosis and combination taping groups than pre-intervention values. [AQ9] Moreover, the post--intervention values of the double support duration of the ankle foot orthosis and combination taping groups were significantly lower than pre-intervention values. There were no significant differences between the post-intervention values of the ankle foot orthosis and combination taping groups for all parameters. Conclusion: The results demonstrated that combination taping is an effective alternative technique to ankle foot orthosis to improve spatiotemporal parameters in children with spastic diplegic in combination with conventional physiotherapy.

This study was conducted to compare the effects of three ankle-foot orthosis (AFO) designs on walking after stroke and determine whether an ankle plantar flexion contracture impacts response to the AFOs. A total of 30 individuals, ranging from 6–215 months post-stroke, were tested in four conditions: shoes only (SH), dorsi-assist/dorsi-stop AFO (DA-DS), plantar stop/free dorsiflexion AFO (PS), and rigid AFO (Rigid). Kinematics, kinetics, and electromyographic (EMG) activity were recorded from the hemiparetic lower extremity while participants walked at a self-selected pace. Gait parameters were compared between conditions and between participants with and without a moderate ankle plantar flexion contracture. All AFOs increased ankle dorsiflexion in swing and early stance. Anterior tibialis EMG was reduced only in the PS AFO. Both PS and Rigid AFOs restricted ankle plantar flexion and increased knee flexion in loading. Peak ankle dorsiflexion in stance and soleus EMG intensity were greatest in the PS AFO. The Rigid AFO tended to restrict dorsiflexion in stance and knee flexion in swing only in participants without a plantar flexion contracture. Individuals without a contracture benefit from an AFO that permits dorsiflexion mobility in stance and those with quadriceps weakness may more easily tolerate an AFO with plantar flexion mobility in loading.
