Abstract

Neuromuscular Electrical Stimulation (NMES) systems are used worldwide to restore upper and lower limb functions in spinal cord patients. An integrated approach is being tried at UNICAMP, including multichannel stimulators, sensors and algorithms for closed-loop control, and artificial proprioception. This paper describes some of the devices developed and their applications, aiming at achieving well elaborated control strategies towards an effective man-machine system
