Study Summary
The investigators performed a feasibility trial of operant conditioning of spinal reflex excitability on five healthy individuals and two post-stroke individuals. The investigators found that operant conditioning of rectus femoris reflex excitability was feasible in all participants.
Primary Outcome
H-reflex magnitude of rectus femoris. Lower values are considered better. The H-reflex is the amplitude of the monosynaptic spinal reflex, elicitied by electrical stimulation of the femoral nerve, normalized by the preceding M-wave. The M-wave is the amplitude of the muscle activity response to surface electrical stimulation of the femoral nerve. All muscle activity measured at the individual's rectus femoris of the stimulated limb. A value of 100% would mean no change in reflex magnitude, where
