The authors used FES to treat a patient with C5 tetraplegia, finding that this stimulation enabled the patient to use his hands for drinking from a glass without help. [Note that FES has bee successfully used in much more sophisticated computerized stimulation systems by others]

Improvement of grasping function with FES in a patient with C5 tetraplegia.]. Unfallchirurg 108: 587-590. The aim of this study was to restore the grasp function of a tetraplegic patient with a C5 spinal cord injury (SCI) by means of functional electrical stimulation (FES). Using three pairs of surface electrodes and orthotic wrist stabilisation a simple palmar grasp was realised.The FES was controlled with a switch mounted on a wheelchair or-for the first time-with an EEG-based brain-computer interface (BCI). Application of this stimulation system enabled the patient to drink for the first time after the accident from a glass without any additional help.
