Muscular rigidity and atrophy caused by long-term underactivity usually lead to foot drop, strephenopodia, foot extorsion or some other complications for the lower limb movement disorders or lower limb surgery sufferers. The ankle-foot orthosis can help patients conduct the right ankle motion mode training, inhibit spasm and prevent ankle complications. In this paper, a quasi-passive 3 DOFs ank...

Background: Ankle fractures in diabetics with secondary complications are more prone to postoperative complications than ankle fractures in diabetics without secondary complications. This study retrospectively compared the post injury complications of foot and ankle fractures in diabetics with and without secondary complications. Secondary complications of diabetes mellitus include peripheral a...

BACKGROUND Botulinum toxin is commonly used to treat spastic equinus foot. This treatment seems to improve gait in hemiplegic patients when used alone or combined with an ankle-foot orthosis. However, the nature and effects of this improvement have until now rarely been studied. The aim of this study was to quantify the impact of a Botulinum toxin injection in the triceps surae of hemiplegic pa...

Materials and method The static range of ankle joint dorsiflexion was measured with the knee flexed and extended (n=100). Dynamic foot kinematics were measured for the tibia, calcaneus, midfoot, lateral forefoot, medial forefoot and hallux, and 13 parameters derived to characterise foot kinematics (right foot only). The relationship between static range of ankle joint dorsiflexion and sagittal ...

BACKGROUND AND PURPOSE The self-reported foot and ankle score (SEFAS) is a questionnaire designed to evaluate disorders of the foot and ankle, but it is only validated for arthritis in the ankle. We validated SEFAS in patients with forefoot, midfoot, hindfoot, and ankle disorders. PATIENTS AND METHODS 118 patients with forefoot disorders and 106 patients with hindfoot or ankle disorders compl...

The durability and function of three ankle-foot prostheses fabricated using a naturally articulated, fresh cadaveric human bone endoskeleton set in a fiber reinforced rubber shell were studied. Radiographic and force-deflection analyses before and after cyclic dorsiflexion for 5,000, 100,000, and 3 million cycles revealed no structural or functional changes. The endoskeleton foot compared favor...

BACKGROUND Although approximately one-third of stroke survivors suffer abnormal foot posture and this can influence mobility, there is very little objective information regarding the foot and ankle after stroke. OBJECTIVE As part of a programme of research examining foot and ankle biomechanics after stroke, we investigated multi-planar kinematics and the relationship with function. METHODS ...

Powered ankle-foot orthosis can not only prevent foot-drop and assist patients’ walking but also improve the ankle joint movement for patients with dysfunction caused by the various injuries and nervous system diseases. Common ankle rehabilitation devices limit the ankle injury patients’ rehabilitation training within fixed places, so a portable powered ankle-foot orthosis is presented in this ...

OBJECTIVE To understand the mechanical and sensorimotor adaptations that may occur with ankle osteoarthritis (OA). DESIGN Case-control. SETTING Biodynamics research laboratory. PARTICIPANTS Subjects with ankle OA (n=8; 4 males, 4 females) were matched to healthy controls (n=8; 4 males, 4 females). INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Mechanical joint stability was asses...

[Purpose] This study compared and analyzed use of an existing ankle ramp and a newly developed ankle ramp for stretching exercises. [Subjects] Fourteen subjects were included; they were stroke patients more than 6 months after onset, with no orthopedic or biological problems in the legs, so independent gait was possible. [Methods] The subjects performed stretching exercises for 5 min with an ex...
