title: [Anatomophysiological consideration on the sacral reflex].
abstract: Sacral reflex testing is a very specific one. Coming from sensory receptors afferent neuronal pudendal passway enters the spinal cord S2 to S4 via spinal dorsal roots and transmits the bioelectrical activity to a complex interneuronal circuitry. Information is processed at this level and dispached into spinal motoneurones for innervating the pelviperineal muscles according to their specific radicular origins. Selective staged sacral reflexes contribute to locate the site of compression. Sacral reflex configuration was based on clinical and electrophysiological findings which is actually confirmed and valided by anatomical studies. This testing is the most efficacious and useful procedure of assessing the pudendal neuralgia, the S2 to S4 reflexes and the pelvic floor dysfunctions.
