Muscle Delay Characterization

To measure the delay, the motor will take the tricycle crank to pre-specified angles and then hold that position while various combinations of the quadriceps femoris and the gluteal muscle groups are stimulated in study participants.

To determine the effect of the crank angle on the FES delay and the muscle control effectiveness, the crank is positioned at a pre-specified angle, with various muscle groups being stimulated while holding this position. The motor then takes the crank to another angle and the process is repeated.
