Interactions of costimulated muscle in paraplegics

Abstract

The torque production of electrically stimulated short-head biceps and quadriceps muscles in complete paraplegic subjects is investigated. During isometric costimulation of this agonist-antagonist pair, the resultant torque is not the simple sum of the torque of the muscles if they were stimulated separately. This has important implications for the use of costimulated muscle in FES neuroprosthetic devices.
