Simultaneous stimulation of SR and SP nerves produces significantly amplified LLR in VL muscle during locomotion. Group data across all subjects for all experimental conditions are shown. Reflexes evoked by simultaneous SR + SP stimulation during locomotor activation (arm & leg cycling) are significantly larger than those from independent SR or SP stimulation or the simple summation of SR and SP delivered independently. Abbreviations: SR, superficial radial nerve; SP, superficial peroneal nerve; SR + SP, simultaneous combined stimulation of SR and SP nerves; SUM, mathematical summation of independent SR and SP reflexes.
