Question: Does acute lumbosacral nerve stimulation affect anorectal motor function in a rodent model?
Answer: The absence of effect on the motor pathways of continence suggests that the mechanism of action is predominantly on sensory feedback mechanisms from the anorectum, thereby increasing cortical awareness of the pelvic floor.
Output:
no
