Background: Amputee reaction to artificial limb is an important issue faces amputated individuals and the team who delivers services to these individuals. Although some individuals using artificial limb accept it, some others don’t. There are several factors that may make it difficult to accept the artificial limb for a long time. Aim: The aim of this study is to investigate some variables asso...

Some diseases or spinal cord injury completely destruct the sensory, motor and autonomous function for the limb movement. BCI (Brain computer Interface) provides a new communication pathway for those patients. Imagination of limb movements is used to operate a BCI. With analysis of acquired EEG signal due to motor imagery controlling of an artificial limb is possible. For this technique motor i...

the performance of the upper limb amputees is significantly reduced in contrast to that of normal subjects.  in order to compensate the functional limitation of the amputees various kinds of prostheses have been designed and developed, which are divided in to mechanical, cosmetic and myoelectric ones based on their functional abilities. unfortunately, most of the upper limb amputees prefer to n...

This paper provides evidence that limb-deficient subjects who wear artificial arms tend to overestimate the perceived length of their residual limb. It is proposed that this "perceptual error" may provide a useful and possibly more valid alternative to existing methods of determining prosthetic acceptance. The degree of overestimation is substantial for most subjects with amputations, and typic...

Existing prosthetic limbs do not provide amputees with cutaneous feedback. Tactile feedback is essential to intuitive control of a prosthetic limb and it is now clear that the sense of body self-identification is also linked to cutaneous touch. Here we have created an artificial sense of touch for a prosthetic limb by coupling a pressure sensor on the hand through a robotic stimulator to surgic...

artificial neural networks are used in many smart apparatus and different fields such as signal processing pattern diagnoses, military systems, medicine, financial systems, and artificial intelligence. in this article using quality of neural networks in optimizing energy cost in moving limb and its effectiveness in organization a cognitive function founded by presenting an algorithm for use in ...

The sense of body ownership represents a fundamental aspect of our self-awareness, but is disrupted in many neurological, psychiatric, and psychological conditions that are also characterized by disruption of skin temperature regulation, sometimes in a single limb. We hypothesized that skin temperature in a specific limb could be disrupted by psychologically disrupting the sense of ownership of...
