Summary

Functional electrical stimulation (FES) induced cycling is a common rehabilitative therapy. Closed-loop FES control holds the promise to improve rehabilitation procedures. However, FES results in a delay between the time of stimulation and muscle contraction and rapidly fatigues muscle. The purpose of this study is to measure the FES-induced delay on an FES cycle and to understand how the delay varies as a function of how long the user has been cycling and a function of the crank angle.

Conditions

Interventions

DEVICE

Functional Electrical Stimulation (FES) Control Protocol

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.

DEVICE

Functional Electrical Stimulation (FES) Angle Protocol

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.
