The effect of prosthesis mass on the metabolic cost of steady-state walking was studied in ten male non-vascular trans-tibial amputees (TTAs) and ten non-amputee controls. The subjects underwent four trials of treadmill ambulation, with each trial performed for nine minutes at level grade and 76 m/min. Twenty minutes of seated rest followed each trial. During trials numbers one and two, TTAs am...

Motivation: A locomotion control system could be used in active orthotics; orthotic braces with actuators attached to augment the muscles of a patient. This would allow patients with a variety of neuro-muscular ailments to walk in an easier, more natural way than is currently possible with passive orthotics. A similar technology could be used for prosthetics to assist patients with amputations ...

During the next decade CAD/CAM technique will probably become routine in prosthetics and orthotics, not only as a complement to manual techniques, but also introducing new possibilities. However, even complex and sophisticated techniques have errors of measurement that must be considered. Such errors are of two principal kinds: systematic errors and random errors. In this study we have evaluate...

One of the modern trends in prosthetics and orthotics is production design covers for lower limb prostheses. Thanks to advantages CAD/CAM, there are no limits these covers. At present, companies that provide produced by additive manufacturing, but their price relatively high. In this work, motivation procedure an individual cover a prosthesis specific user discussed. The aim study propose metho...

1 This article appeared originally in the September 1965 issue of the Orthopedic and Prosthetic Appliance Journal, having been prepared at the request of the Committee on Advances in Prosthetics and Orthotics of the American Orthotic and Prosthetic Association. It is being republished in Artificial Limbs in the belief that the device and procedure described will be of interest to our readers. T...
