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: foot and ankle problems are common complications in rheumatoid arthritis disease. gait pattern such as normal foot and ankle rocker is impaired in patients with rheumatoid arthritis. rocker sole as an external shoe modification is commonly prescribed in this pathology. the aim of this study was to investigate the effect of rocker shoe on vertical ground reaction force parameters dur...

The neuropathic foot is a common complication of diabetes mellitus and is associated with development of chronic ulcers and Charcot joints. Treatment of these complications presents a complex management task. This report presents long-term follow-up data on 16 patients with neuropathic changes who were treated with a total contact, laminated, bivalved, rocker-bottom-soled ankle-foot orthosis (T...

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...

Previous studies have shown that the effective rocker shape of the physiologic ankle-foot system during standing and fore-aft swaying is much flatter than that used during walking, which indicates a more stable base of support for the standing/swaying activity. Previous work suggests that flat regions within the effective rocker shapes of prosthetic ankle-foot systems could provide enhanced sta...

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...

Ankle-foot orthoses (AFOs) have been described to have positive effects on the gait biomechanics in stroke patients. The plantarflexion resistance of an AFO is considered important for hemiplegic patients, but the evidence is still limited. The purpose of this case series was to design and evaluate the immediate effect of an articulated AFO on kinematics and kinetics of lower-limb joints in str...
