<strong>Research: </strong>After amputation, amputees lose their mechanical ability in addition to their sensory feedback pathways. Mechanical abilities have been partially recovered through the use of different prosthetic arms, however, amputees must rely extensively on visual, auditory and other cues to manipulate the arm. Electrical stimulation of the peripheral nerves in the arm has been shown to be successful in evoking referred sensations. Through these studies, Luis plans to investigate the effects of different parameters of non-invasive, surface electrical stimulation, of peripheral nerves in the area of the wrist of able-bodied participants. The number and location of the electrodes, as well as other parameters such as pulse frequency and interleaved time, will be examined.
