Upper extremity assistive devices prescribed during the rehabilitation of the patient with quadriplegia often are discarded once the patient leaves the hospital. Therefore, we conducted this study to investigate patterns of the prescription and use of such devices and satisfaction with them. An oral questionnaire was administered to 56 spinal cord-injured quadriplegic patients 1 and 2 years aft...

Cutaneous pain experienced during locomotor training was previously reported to interfere with retention assessed in pain-free conditions. To determine whether this interference reflects consolidation deficits or a difficulty to transfer motor skills acquired in the presence of pain to a pain-free context, this study evaluated the effect of pain induced during both the acquisition and retention...

We report five examples of physeal widening in four children with myelomeningocele. In all cases there was rapid clinical resolution with the use of the patients' normal orthoses and minor limitation of activity, and there was no evidence of early epiphyseal closure or growth disturbance. We suggest that recognition of the pathological process before fracture occurred may explain the rapid retu...

The authors described 424 orthopaedic appliances left by the prisoners of the Nazi Concentration Camp in Oświęcim. A collection of prostheses and orthoses, which is currently a part of the Auschwitz-Birkenau State Museum's exhibition, is extraordinary as it illustrates the fate of innocent, crippled people, who were incarcerated and murdered. Another point of value of the collection is its tech...

This contribution presents a new approach of estimating the joint torques for an active orthosis. The new approach combines inverse dynamics and measured ground reaction forces. The joint torques can easily be computed from the ground reaction forces, but the measurement is usually flawed. An obsererver is employed to estimate the disturbance of the measurements and restore the original joint t...

Plastics are extensively used as a material for orthoses. However, one remaining problem is the ventilation of the orthosis. This is a real problem in countries such as Japan, where it is hot and humid especially in summer. The authors have invented a new orthosis "POROPLAST", which is made of mesh plastic sheets, combined in a cross-like weave. These orthoses provide good ventilation and are v...

Background Foot problems are highly prevalent in older people, and prefabricated (‘off-the-shelf’) foot orthoses are frequently prescribed in this age-group. However, such devices are susceptible to material compression and deformation, which may reduce their effectiveness over time. Therefore, the aim of this study was to investigate the difference in plantar pressures between prefabricated or...

[Purpose] This study attempted to examine the impact on the pattern of walking on both level ground and stairs after restricting the movement of the spine and the trunk of the body by using a spinal orthosis. [Subjects and Methods] Forty healthy males in their 20s were selected as the sample, which was randomly and evenly divided into two groups: (1) the WT group (with a thoracolumbosacral orth...

Force plate studies with nine adult traumatic complete paraplegics with lesion at thoracic level have shown that, unlike children walking in the Oswestry Hip Guidance Orthosis (Para Walker) system, they have to apply extra stabilizing forces through the crutches for safe walking. These forces are described and are attributed to an increased crutch force applied to prevent lateral deformation of...
