Two different patterns of reflex changes occurred. One pattern was associated with easy initiation of voiding: it consisted of increasing H and T reflexes and decreasing flexor reflexes with concomitant decreasing sphincter muscle activity. The other pattern was associated with difficulty in initiation of voiding: it consisted of increasing flexor relfexes including sphincter muscle activity and decreasing H and T reflexes. The importance of these reflex patterns in disturbances of micturition is discussed. During voiding, decreasing flexor relfexes with increasing H and T reflexes occur as the general pattern.
