Methods Data was collected from 26 patients (12 males, 12 right ankles, mean age 32.88 years) from November 2004 to March 2011. 20 patients were available for follow up. Preoperative MRI scans and stress radiographs were taken. The patients were all assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) anklehindfoot scale, Manchester-Oxford Foot Questionnaire, EuroQol and the V...

osteosarcoma of the foot is rare and, when presents, commonly observed in adults. we report a case of osteosarcoma of the calcaneus in an 11-year-old girl who was presented with a 4-month history of pain and swelling on her left ankle and inability to walk in her left lower extremity. on examination, there was a diffuse swelling involving her left ankle joint and foot. the radiograph showed sof...

This paper describes the development of a novel humanoid robot foot/ankle based on an orientation Parallel Kinematic Mechanism for intelligent and flexible control. With three identical Universal-Prismatic-Spherical prismatic-actuated limbs and a central Universal-Revolute passive limb, the PKM can perform three degrees of freedom rotation motions. In order to enable the humanoid robot safely t...

[Purpose] The purpose of this study was to examine the effects of increasing physical activity on foot structure and ankle muscle strength in adults with obesity and to verify whether the rate of change in foot structure is related to that in ankle muscle strength. [Subjects and Methods] Twenty-seven adults with obesity completed a 12-week program in which the intensity of physical activity per...

In foot and ankle patients, the use of Kirschner wires is common, and the population in the typical foot and ankle practice has higher rates of comorbidities associated with infection. This study assessed national trends regarding the use of postoperative prophylactic antibiotic therapy in patients undergoing foot and ankle surgery treated with percutaneous Kirschner wires. Attending physicians...

OBJECTIVE To assess the efficiency of knee-ankle-foot orthoses for treating painful genu recurvatum, and to determine users' tolerance and satisfaction. PATIENTS Patients included in the study had a genu recurvatum during the stance phase, confirmed by a medical doctor on physical examination. A total of 27 patients with 31 knee-ankle-foot orthoses were included. METHODS The main outcome wa...

OBJECTIVE From early onset of the disease, patients with rheumatoid arthritis (RA) experience walking impairments. Pathologic effects of RA on foot and ankle structures have been studied clinically, but little is known as to how they relate to kinematic changes during gait. The aim of this study was to explore the relationship between clinically observed pathologies of foot and ankle joints and...

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 Foot involvement in rheumatoid arthritis (RA) patients has been reported to severely affect functional capacity and quality of life. We aimed to determine the impact of midfoot and hindfoot involvement on functional disability in Korean patients with RA. METHODS We evaluated the RA involvement and deformity of three regions of the foot (forefoot, midfoot and hindfoot) and ankle usi...

The aim of this work is to propose a new 2-DOF robotic platform with hybrid parallel-serial structure and to undertake its parametric design so that it can follow the whole range of ankle related foot movements. This robot can serve as a human ankle rehabilitation device. The existing ankle rehabilitation devices present typically one or more of the following shortcomings: redundancy, large siz...
