sacral nerve

One of five pairs of dorsal or five pairs of ventral spinal nerves originating in the sacral segments of the spinal cord.


The dorsal sacral spinal nerves innervate the skin and fascia over the sacrum and the medial gluteal region. The ventral sacral spinal nerves innervate the sacrospinous and sacrotuberous ligaments and the skin of the perineum.


The dorsal sacral spinal nerves innervate the lower multifidius muscles. The ventral sacral spinal nerves innervate the coccygeus and levator ani muscles.

The device delivers mild electrical stimulation to the sacral nerves that control the bladder, sphincter, and pelvic floor muscles.
Sacral nerve stimulation in patients with chronic intractable pelvic pain.
Alternatively, an implanted sacral nerve electrical stimulator device may be a more practical solution especially if its utility can be demonstrated noninvasively.
Based on application, the Neuromodulation Market is segmented into technology-wise applications, such as spinal cord stimulation (chronic pain, failed back surgery, ischemia); deep brain stimulation (Parkinson's disease, tremor, depression, others); sacral nerve stimulation (urine incontinence, fecal incontinence); vagus nerve stimulation (epilepsy, others); gastric electrical stimulation (gastro paresis, obesity); transcutaneous electrical nerve stimulation (treatment resistant depression, others); and transcranial magnetic stimulation (depression, migraine headaches).
All patients underwent sacral neuromodulation, in which an electrode is inserted with a needle into the S3 sacral nerve and then hooked up to an external box the patient carries for 2-3 weeks.
The neuromodulation devices market is segmented on the basis of technology into: Spinal Cord Stimulation Devices, Deep Brain Stimulation Devices, Vagus Nerve Stimulation Devices, Sacral Nerve Stimulation Devices and Gastric Electric Stimulation Devices.
The types include the spinal cord stimulator, deep brain stimulator, gastric electrical stimulator, vagus nerve stimulator and sacral nerve stimulator.

In this study, we demonstrated that non-invasive sacral nerve stimulation using TAMS reduced CGRP content at L6 DRG which may therefore explain the modulatory effect on the C- fibre afferents supplying the urinary bladder.
At three centers in the United Kingdom, 57 of 59 patients who were temporarily implanted with sacral nerve stimulators had improved continence after 3.
