Bulbocavernosus or anal reflex, one or both should be tested after spinal cord injury

Abstract

There are several methods for determining the remaining function of the sacral spinal cord following a spinal cord injury. Two of these methods are the bulbocavernosus and the anal wink reflexes. The choice of which reflex to use should be determined by the need for clinical information. These two reflexes provide similar information; however, they may have different prognostic value.
