Developments towards a Psychophysical Testing Platform - A Computerized Tool to Control, Deliver and Evaluate Electrical Stimulation to Relieve Phantom Limb Pain

Artificially inducing phantom hand sensations by electrical stimulation may reduce PLP. The use of implantable, multi-channel microelectrodes provides the opportunity to selectively activate sensory fibres. However, combinations of variables from a multichannel stimulation system can produce a huge number of possible stimulation paradigms. It makes the use of psychophysical evaluation of the evoked sensations an impractical and time-consuming task in the clinical setting. Our aim is to develop a computerized, automatic, psychophysical testing platform to support control, delivery and evaluation of the electrical stimulation for PLP relief.
