TETRAGRIP II - Usability Trial of an FES Orthosis for People With Tetraplegia.

"This main aim of this whole research project is to evaluate the performance of the TetraGrip II system in improving the upper limb functions in people with C4-C7 tetraplegia i.e. people who have damaged their spinal cord in the neck resulting in loss of function in all four limbs. The Tetragrip system uses a technique called Functional Electrical Stimulation (FES) in which small electrical impulses are used to activate paralysed muscles and hence provide movement. The stimulation is controlled by sensors which measure the movement of the other shoulder and enable the person to regain the use of their hand via stimulating electrodes placed on the skin over the relevant muscles.~The feasibility of using this FES based system in restoring the upper arm functions will be evaluated by clinically trying the device on participants with C4-C7 tetraplegia."
