This paper reports on the design of a biorobotic actuator intended for use in a powered, below-knee prosthesis. Design requirements for the artificial muscle and tendon are based on the properties of the natural limb. As biological properties often exhibit significant variability, data from a variety of vertebrate species are extracted from published reports in the biological literature and use...

The human proprioception is one of the mechanisms utilized to recognize location different segments or body parts, also identify them in space; problem comes when loss a nervous pathway (e.g., due amputation limb). Given background literature and technological development, this work's purpose establish definition demarcate methodology for Artificial Proprioception persons who have lost their na...

Arm rotation is very useful for unilateral amputees and essential for bilateral amputees to perform tasks of daily living. We propose a new approach for improving the control of prosthetic arm rotation in amputees. This new approach involves inserting a small permanent magnet into the distal end of the residual bone of subjects with upper limb amputations. When a subject rotates the residual ar...

embolectomy has long been the gold standard for treating limbs acutely threatened by arterial occlusion. delayed embolectomy has not been investigated adequately due to the belief that accompanying mortality and morbidity render the case futile. following our previous experience with late arterial repair for leg or knee salvage i we applied the same principle to limbs threatened with prolonged ...

Early in 1945, at the request of the Surgeon General of the Army, the National Research Council sponsored a conference of surgeons, engineers, physicists, and prosthetists to consider the feasibility of effecting improvements in artificial limbs . Conclusions that emerged from the conference were that virtually no organized research of significance had been conducted in the field of limb prosth...

The emergence of skeletal prosthetic attachments leaves governmental organizations facing the challenge implementing equitable policies that support provision bone-anchored prostheses (BAPs). In 2013, Queensland Artificial Limb Service (QALS) started a five-year research project focusing on health service delivery and economic evaluation BAPs. This paper reflects QALS experience, particularly l...

The aim of this hapter is to summarize results we have obtained over the past five years of the bio-mimetic approach to robotics and/or prosthetic applications . Focusing on multiple degrees of freedom (dof) and multi-articulated limbs we will suggest technical solutions for controlling and planning the motion of an artificial limb in such a way that it will match the natural pattern of ‘natura...
