A new concept of device, termed the weight-bearing control (WBC) orthosis, has been designed with three major needs in mind; a rigid frame that supports the user's body weight, a special hip joint device that reciprocally propels each leg forward, a gas powered foot device that varies the sole thickness of the device for foot/floor clearance, and control system of the orthosis. A paraplegic (T7...

INTRODUCTION This paper deals with the dynamic modelling of human walking. The main focus of this research was to optimise the function of the orthosis in patients with neuropathic feet, based on the kinematics data from different categories of neuropathic patients. METHODS The patient's body on the sagittal plane was modelled for calculating the torques generated in joints. The kinematics da...

This study aimed to understand how systematic changes in arch height and two designs of heel wedging affect soft tissues under the foot. Soft tissue thickness under the heel and navicular was measured using ultrasound. Heel pad thickness was measured when subjects were standing on a flat surface and standing on an orthosis with 4 and 8 degree extrinsic wedges and 4 mm and 8 mm intrinsic wedges ...

Orthosis and prosthesis is an expert knowledge in medical field including the design, fabrication and utilizing of orthosis and prosthesis. An orthosis is a device made of different types of material (plastic, aluminum, foam, leather, etc.) used externally on body segments to modify the structural or functional characteristics of musculoskeletal system to objectives such as: reducing pain, rest...

Foot and ankle-foot orthoses are prescribed in order to promote mobility through supporting and/or realigning the lower leg and alleviating pain in the foot in different parts of the gait cycle. This paper will outline new approaches to the design and manufacture of personalised foot and ankle-foot orthoses (FO and AFO) using additive fabrication technology. The research is addressing the need ...

abstract introduction: multiple sclerosis (ms) is an autoimmune disease which affects the skeletal muscles and optical neural networks. weakness of ankle dorsi flexion and hip flexion muscles is commonly seen in consequence ms. the ankle foot orthosis (afo) is the most frequently prescribed orthoses to compensate for these weaknesses. it is generally believed that patients are commonly dissatis...

• Statistical non-parametric mapping explores effect over the entire kinematic curve. Medial heel bar reduces rearfoot eversion for majority of stance phase. Retrocapital rotates externally Sensorimotor foot orthoses is an alternative concept, which in addition to mechanical effects, are designed change muscle activation by altering sensory input plantar surface foot. However, there little evid...

PURPOSE Patients with diabetes are often prescribed foot orthoses to help prevent foot ulcer formation. Orthotics are used to redistribute normal and shear stress. Shear stresses are not easily measurable and considered to be responsible for skin breakdown. Local elevation of skin temperature has been implicated as an early sign of impending ulceration especially in regions of high shear stress...

Plantar foot pain is one of the most common musculoskeletal conditions affecting foot. It regularly experienced by population with occupations that require prolonged standing hours, especially in nurses. The etiology plantar remains unclear, but it likely to be multi-factorial, many associated risk factors including increased hours standing. Orthoses and insoles are often recommended patients, ...

Little or no practical decision-making data are available to the foot-care provider regarding the selection of orthotic materials used in therapeutic footwear. A device for simulating in-shoe forefoot conditions for the testing of orthosis materials is described. Materials are tested for their effectiveness by evaluating and comparing stress-strain and dynamic compression fatigue characteristic...
