Study 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.
Primary Outcome
A torque meter (SRM Science PowerMeter) is attached to the tricycle's crank to provide instantaneous feedback of the rider torque. A combination of muscle groups will be stimulated and the resulting crank torque will be measured by the meter.
Interventions
- DEVICE Functional Electrical Stimulation (FES) Control Protocol
- DEVICE Functional Electrical Stimulation (FES) Angle Protocol
