Muscle Delay Characterization

Muscle Delay Characterization

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.

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.
