Pengaruh Penggunaan Ankle Foot Orthosis Dinamis Terhadap Kecepatan Jalan Pada Anak Penderita  Cerebral Palsy

Background: cerebral palsy is a non-progressive motor disorder that causes limited activity, paralysis, inability to control motion and is often accompanied by cognitive impairment or visual deficits.Children who experience cerebral palsy will definitely have limitations in the process of mobility. To help limitation of activity that occurs in children with cerebral palsy, ankle foot orthosis is used. Ankle foot orthosis is expected to help the patient in performing his activities at all times to give effect on the walking speed. In this research, actions performed by taking data before and after using dynamic ankle foot orthosis. Purpose of this research to determine the effect of the use of dynamic ankle foot orthosis on walking speed in children with cerebral palsy ". Methods: This type of research is quasi experimental pre and post test design. The subjects used were spastic cerebral palsy spherical patients in the Pediatric & Neurodevelopmental Therapy Center (PNTC) who had determined the inclusion and exclusion criteria. Number of subjects 15 people. Result: This research is based on data analysis result that wilcoxon test value got p = 0,001 (p <0,05). Conclusion: This result indicates that there is an effect of the use of ankle foot orthosis dynamic on road speed in children with cerebral palsy.

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.

Walking Energy Cost

A rigid ventral shelf ankle foot orthosis (AFO) may improve gait in children with spastic cerebral palsy (SCP) whose gait is characterized by excessive knee flexion in stance. However, these AFOs can also impede ankle range of motion (ROM) and thereby inhibit push-off power. A more spring-like AFO can enhance push-off and may potentially reduce walking energy cost. The recent development of an adjustable spring-hinged AFO now allows adjustment of AFO stiffness, enabling tuning toward optimal gait performance. This study aims to quantify the mechanical properties of this spring-hinged AFO for each of its springs and settings. Using an AFO stiffness tester, two AFO hinges and their accompanying springs were measured. The springs showed a stiffness range of 0.01−1.82 N·m·deg−1. The moment-threshold increased with increasing stiffness (1.13–12.1 N·m), while ROM decreased (4.91–16.5°). Energy was returned by all springs (11.5–116.3 J). These results suggest that the two stiffest available springs should improve joint kinematics and enhance push-off in children with SCP walking with excessive knee flexion.

Background: A powered knee–ankle–foot orthosis was developed to provide restriction of knee flexion during stance phase and active flexion and extension of the knee during swing phase of gait. Objective: The purpose of this study was to determine its effect on the physiological cost index, walking speed and the distance walked in people with poliomyelitis compared to when walking with a knee–ankle–foot orthosis with drop lock knee joints. Study design: Quasi experimental study. Methods: Seven subjects with poliomyelitis volunteered for the study and undertook gait analysis with both types of knee–ankle–foot orthosis. Results: Walking with the powered knee–ankle–foot orthosis significantly reduced walking speed ( p = 0.015) and the distance walked ( p = 0.004), and also, it did not improve physiological cost index values ( p = 0.009) compared to walking with the locked knee–ankle–foot orthosis. Conclusion: Using a powered knee–ankle–foot orthosis did not significantly improve any of the primary outcome measures during walking for poliomyelitis subjects. Clinical relevance This powered knee–ankle–foot orthosis design did not improve the physiological cost index of walking for people with poliomyelitis when compared to walking with a knee–ankle–foot orthosis with drop lock knee joints. This may have been due to the short training period used or the bulky design and additional weight of the powered orthosis. Further research is therefore warranted.

Foot Orthosis

This paper reports on a series of case studies where improvements were sought in muscle tone and gait in children with cerebral palsy. A Midfoot Control Ankle Foot Orthosis (AFO) was developed to control foot position in a cohort of patients with cerebral palsy (CP). The concept of controlling midfoot and hindfoot with an encapsulated internal Supra-Malleolar AFO that fitted into an external AFO was shown to be effective in ambulant children with CP. Some initial problems of compliance were noted and postulated to be due to difficulties associated with previous orthotic devices. Evidence from the case studies suggest that the developed Supra-Malleolar AFO orthoses enables children with CP to maintain mobility without skin tissue damage, delays the need for surgery and at the same time maintains the length of the Triceps Surae (Gastrocnemius and Soleus) complex. Plans for further research are discussed which will contribute to the evidence base for this particular orthotic device.
