CONTEXT Foot-orthosis (FO) intervention to prevent and treat numerous lower extremity injuries is widely accepted clinically. However, the results of quantitative gait analyses have been equivocal. The foot models used, participants receiving intervention, and orthoses used might contribute to the variability. OBJECTIVE To investigate the effect of a custom-molded FO intervention on multiseg...

[Purpose] Observational study investigating the influence of various ankle-foot orthoses on the spatiotemporal gait parameters and functional balance in chronic stroke patients. [Subjects and Methods] Fifteen chronic stroke patients participated in this study after providing informed consent. Two groups of patients were differentiated based on the Timed Up and Go Test. Patients were tested in t...

Material and methods TCFO is foot orthosis which combines inverted rigid foot orthosis(RFO) with broad upright portion that covers and protects the talonavicular joint, rising well above the navicular. Fourty children were participated in this study who had been diagnosed as flexible pes planus, and had more than two consecutive radiologic studies. The anteroposterior talocalcaneal angles (APTC...

BACKGROUND Despite evidence for use of foot orthoses in the treatment of anterior knee pain, there is a paucity of research into their mechanisms of action. This study (i) determined the immediate lower limb kinematics and muscle activity adaptations, and (ii) evaluated the effect of individual's comfort and foot mobility. METHODS Forty individuals diagnosed with anterior knee pain were measu...

Background For the flat foot deformity, the custom made foot orthosis supported medial longitudinal arch using the navicular pad. And we experienced many cases that addition the metatarsal pad which supported transverse arch of the forefoot was more effective treatments. However, the flexibility of the transverse arch in the flat foot deformity was unclear. The aim of this study was to clarify ...

We constructed a powered ankle-foot orthosis for human walking with a novel myoelectric controller. The orthosis included a carbon fiber and polypropylene shell, a metal hinge joint, and two artificial pneumatic muscles. Soleus electromyography (EMG) activated the artificial plantar flexor and inhibited the artificial dorsiflexor. Tibialis anterior EMG activated the artificial dorsiflexor. We c...

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 si...

An active orthosis was designed to support users with reduced muscle strength with an additional knee joint torque to improve the independency in everyday activities. In two persons the hypothesis was tested that less muscle activity is necessary when standing up with the active support of a motorized orthosis. The orthosis is a custom-made knee-ankle-foot orthosis and is equipped with a series...

[Purpose] This study examined the effects of an ankle-foot orthosis worn during balance training on lower limb muscle activity and static balance of chronic stroke patients. [Subjects] The subjects were twenty-five inpatients receiving physical therapy for chronic stroke. [Methods] The chronic stroke patients were divided into two groups: thirteen patients were assigned to the ankle-foot orthos...
