    摘要： Loss or absence of sensibility in the hand, foot or other part of the body can constitute a severe handicap after injury or in disease. Also when hand prostheses are used following amputation, injuries lack of sensibility in the prostheses constitutes a major problem. The prevailing invention refers to a new principle for artificial sensibility by sense substitution (replacement of a lost sense function by utilization of an alternate sense). The primary aim is to, by using the hearing sense, achieve sensibility in hand prostheses or hands which have lost their sensibility by injury or disease. According to this principle vibrotactile stimuli to the fingers are registrated by sensors of microphone type, placed at finger level, the signals being processed and transformated into acoustic stimuli. By using this principle the patient can 'feel with the hearing sense' hereby utilizing the hearing sense to register and identify the surface, texture, density and shape of the item which is touched.

    摘要： A system for alleviating phantom limb pain of a patient having a limb stump is disclosed, said system comprising: a signal generator for producing signals for electrically stimulating selected sensory nerve fibres of a severed limb nerve, the signals approximating a pattern of sensations that would be received from a normal, innervated limb before it was amputated; means to cause the signal generator to produce the signals and to deliver them to the selected sensory nerve fibres in order to alleviate phantom limb pain, the selection of the electrical stimulation signals being based on feedback from the patient; and means for transmitting the signals to the selected sensory nerve fibres. The system is arranged such that the means for transmitting the signals to the selected sensory nerve fibres includes electrodes adapted for implantation in close proximity to the severed limb nerve and wherein each electrode is in close proximity to different sensory nerve fibres of the severed limb nerve.
