INTRODUCTION The floor reaction ankle-foot orthosis is commonly prescribed in the attempt to decrease knee flexion during the stance phase in the cerebral palsy (CP) gait. Reported information about this type of orthosis is insufficient. PURPOSE The purpose of this study was to determine the effect of clinically prescribed floor reaction ankle-foot orthosis on kinematic parameters of the hip,...

BACKGROUND AND PURPOSE This study investigated the non-velocity-related effects of a 1-bar rigid ankle-foot orthosis on the gait of hemiparetic subjects, with particular emphasis on the muscle activity of the paretic lower limb. METHODS Twenty-one hemiparetic subjects who had been using an ankle-foot orthosis for equinovarus deformity for <1 week participated. Patients walked cued by a metron...

BACKGROUND The use of knee-ankle-foot orthoses with drop locked knee joints produces some limitations for walking in subjects with quadriceps muscle weakness. The development of stance control orthoses can potentially improve their functionality. OBJECTIVES The aim of this review was to compare the evidence of the effect of stance control orthoses to knee-ankle-foot orthoses with drop locked ...

BACKGROUND There are clear indications for benefits of stance control orthoses compared to locked knee ankle foot orthoses. However, stance control orthoses still have limited function compared with a sound human leg. OBJECTIVES The aim of this study was to evaluate the potential benefits of a microprocessor stance and swing control orthosis compared to stance control orthoses and locked knee...

objectives: ankle foot orthoses (afos) are widely utilized to improve walking ability in hemiplegic patients. the present study aimed to evaluate the effect of rocker bar ankle foot orthosis (rafo) on functional mobility in post-stroke hemiplegic patients. methods: fifteen hemiplegic patients (men and women) who were at least 6-months post-stroke and able to walk without assistive device for at...

introduction: functional ankle instability has described as a “feeling of giving way”. balance control deficit is one of the sensorimotor impairments observed in people with functional ankle instability that has been described to damage to the afferent receptors within the ligaments and joint capsule that affected during sprain. foot orthosis can improve balance control via enhanced sensory aff...

objectives: this study was designed to evaluate the effectiveness of a modified floor reaction ankle foot orthosis (frafo) design on gait performance in children with cerebral palsy. methods: eight children with cerebral palsy wore a modified frafo bilaterally for six weeks. motion analysis was used to assess the immediate effectiveness of the orthosis on improving gait and also following six w...

We developed a powered ankle-foot orthosis that uses artificial pneumatic muscles to produce active plantar flexor torque. The purpose of this study was to quantify the mechanical performance of the orthosis during human walking. Three subjects walked at a range of speeds wearing ankle-foot orthoses with either one or two artificial muscles working in parallel. The orthosis produced similar tot...

Background: Ankle-Foot orthoses are used to minimize the impact of weakness in ankle dorsiflexion muscles. The study on different orthotic types defines the optimal design, which effectively improves the users’ mobility. This study investigated the potential benefits and risks of a Dictus-band (flexible orthotic), compared with a thermoplastic (fixed) ankle-foot orthosis on the mobility of indi...

objectives: ankle foot orthoses (afos) are widely utilized to improve walking ability in hemiplegic patients. the present study aimed to evaluate the effect of rocker bar ankle foot orthosis (rafo) on functional mobility in post-stroke hemiplegic patients. methods: fifteen hemiplegic patients (men and women) who were at least 6-months poststroke and able to walk without an assistive device for ...
