Conditions
Summary
Upper limb amputation still causes severe disability today; prostheses currently on the market are able to restore partially to the amputee the lost functionality. In addition to the motor capacity of the limb, prosthetic systems should also aim to restore to the sensory information from the surrounding environment during contact with objects. Therefore, it is important to develop bidirectional prostheses. It is thus apparent that the development of new techniques for decoding the efferent channel, such as high-density surface electromyography, and for encoding of the afferent channel afferent, to return multimodal somatosensory sensations of mechanoception, nociception, and thermoception using TENS, isimportant to improve the patient's use of the prosthesis.

Interventions
Measurement of muscle electrical signal with HD-sEMG sensors, training of a pattern recognition classifier for hand gesture recognition, verification and comparison with state of the art.
Application of TENS by means of non-invasive superifical electrodes on the stump skin of the participants to restore multimodal somatotopical sensations of mechanoception, nociception and thermoception.
