About Paper:

The experiments described herein are part of a larger study to develop and operationalize a "humanized" functional electrical stimulation (FES) bicycle system for rats. The long-term goal of that study is to optimize FES parameters to minimize bone loss and/or promote bone recovery in a rat spinal cord injury (SCI) model. The experiments targeted four hindlimb muscle groups (quadriceps, hamstrings, gluteals, and plantar flexors) bilaterally. The goal of this study was to create and control pedaling motion in anesthetized and/or spinalized rats while on the bicycle. The objectives were to 1) determine optimal placement of surface electrodes to restore and control motion; 2) determine the input-output response between electrical stimulation (ES) parameters and multiple motions, including knee extension and flexion, hip extension and flexion, and plantar flexion; and 3) validate the crankshaft angles in which ES should be applied to these specific muscles in comparison with a previously developed mathematical modeling approach that predicted ideal crankshaft angles for ES in each muscle. 191
