    Abstract

    The effects of several stimulation patterns at constant duty cycle on isometric and isokinetic knee torque development and fatigue-induced torque decline in electrically stimulated paralyzed human quadriceps were studied. The benefit of optimizing the interpulse intervals (PISi)n comparison to a repetitive train (constant PIS) increased with the number of stimulation pulses. Application of an optimized pattern on sustained intermittent stimulation resulted in higher torque-time integral ("TI) per cycle. The overall loss had a typical exponential decay reaching asymptotic values.
