Nerve Conduction Velocity Examination Indicated an H-Reflex Latency of Normal

Nerve conduction velocity examination indicated an H-reflex latency of normal value for the S1 nerve roots.What does this tell the therapist?

A) A normal number of motor units were recruited during volitional contraction.
B) The sensory and motor pathways of the S1 nerve root are intact.
C) The sensory pathway of the S1 nerve root is intact,but the motor pathway is slow.
D) There are fewer motor unit action potentials than sensory action potentials produced.
