Multi-channel Textile Neuroprosthesis for Grasping

ZNZ Symposium 2009

Transcutaneous (surface) electrical stimulation (TES) is a widely used technique for producing artificial neural and motor activation in humans[1]. To obtain maximum functional benefit, it is necessary for patients to regularly use the TES systems both at home and in the clinic. However the reapplication of electrodes and connecting cables is time consuming and error prone. Recently, novel textile technology has been developed which enables multi-channel transcutaneous stimulation electrodes to be integrated into a single, wearable garment. Optimal transcutaneous electrode positions for functional grasping were recorded from a group of 10 stroke patients, 2 spinal cord injured patients and 10 healthy volunteers. The results were analyzed using clustering algorithms in order to determine the optimal electrode positions for three different sizes of garment neuroprostheses. A new multi-layer textile technology was used to produce neuroprostheses which contain multiple integrated electrodes and embroidered wires. The multi-layer technology also enables development of water proof, insulated garment which can be worn for long periods. We will present first tests of applying the new garment neuroprosthesis in stroke and healthy subjects.
