Compex Inc 4-channel programmable compex motion noninvasive electrical stimulators
Experimental setup. The computer vision (CV) system and brain–computer interface (BCI) were implemented as two independent systems that could communicate with each other through TCP/IP (transmission control protocol/Internet protocol) networking protocols. The CV system first identified objects placed on a table in front of the participant, determined the grasp necessary to manipulate it, then provided the required grasp to the BCI system. The BCI configured the functional <t>electrical</t> stimulation (FES) system to produce the intended movement. The FES system was implemented using two four-channel electrical stimulators (each capable of producing two different grasps). The BCI used a single EEG electrode. Triggering of the stimulation sequences started when the BCI was activated (event I in figures b, c, d, and e). Activation and deactivation of the stimulation was done gradually by ramping up (or down) its intensity. The facilitated movements included palmar grasp (b), lumbrical grasp (c), lateral grasp (d), and precision pinch (e). All stimulation sequences lasted 8 seconds and ended by facilitating hand opening. This position (opened hand) was sustained for 3 seconds after which the system would return automatically to an idle state, waiting for the next BCI activation.
