One hundred and one patients with through-knee amputations attending the Manchester limb-fitting centre are reviewed. Most amputations were performed for trauma or vascular disease. The interval from amputation to measurement for the first prosthesis averaged 12 weeks in cases of primary healing, and 21 weeks when healing was delayed. Artificial limbs were successfully fitted to 83%, and only 1...

We call the ideal motion generated under the artificial environment like a computer "artificial proficient motion". This paper reports the simulation analysis for upper limb how influence is given to pitching motion from ball mass and shape by using the new simulation method for generating artificial proficient motion. The most important feature of our simulation method is that there is a mecha...

Replacing the function of a missing or paralyzed limb with a prosthetic device that acts and feels like one's own limb is a major goal in applied neuroscience. Recent studies in nonhuman primates have shown that motor control and sensory feedback can be achieved by connecting sensors in a robotic arm to electrodes implanted in the brain. However, it remains unknown whether electrical brain stim...

8 Motor control research relies on theories, such as coordination dynamics, adapted from physical sciences to explain the emergence of coordinated movement in biological systems. Historically, many studies of coordination have involved inter-limb coordination of relatively few degrees of freedom. Moreover, the majority of experimental studies of coordination also involve continuous cyclic movem...

Studies that were conducted by the UCLA Bidtechnology Laboratory developing techniques for enhancing patient control for arm prostheses have produced a variety of upper body muscle transducer control systems, which were reported in the Bulletin of Prosthetics Research (1) and laboratory reports (2,3) . In pursuing this work it was revealed that there is a basic limitation on the ability of a pa...

It is an unfortunate paradox that the advances in medical therapy and care and the increased life expectancy results in an expanding population of physically disabled persons. Many physically disabled suffer from neuronal damage (e.g., stroke or spinal cord injury) that prohibits or disturbs the control of movements; others are amputees that lack a limb or part of a limb. The challenge to assis...

A method is described by which an artificial limb can be fitted as soon as an above-knee or below-knee amputation wound is healed, by using preformed sockets which enable the prosthetist to fit the limb within the hour. The method has been found safe, and better than other methods previously described to facilitate the early mobilisation and rehabilitation of the amputee.
