if a patient responds to dorsal penile nerve stimulation, it is reasonable to suppose that the same afferent fibres can be activated by an implant capable of stimulating sacral roots 2 to 4.

Unilateral injury of the L5, S1, or S2 nerve roots was noted in the zone 2 fractures. Associated neurologic injury, especially of the lower sacral plexus, may not be appreciated unless a thorough ...

Medically reviewed by Brigid Dwyer, MD The most likely causes of numbness on one side of the body include nerve damage, ...

Implantation of the Brindley system has been increasingly supplemented by surgical transection of the sacral sensory nerve roots to reduce hyper reflexia of the bladder (increasing bladder ...

Stimulation of the sacral nerve roots also increases external sphincter tone, causing physiologic inhibition of detrusor motor neurons. Overall, sacral nerve stimulation is thought to have a ...

Previous studies have shown that, anode block electrical stimulation of the sacral nerve root can produce physiological urination and reconstruct urinary bladder function in rabbits. However ...

These perineural/perineurial cysts appear as ballooned areas of the outer covering of the nerve root. The fluid-filled abnormal sacs affect the sacral region of the spine, in particular ...

Axonics sacral neuromodulation (SNM) system (Axonics Modulation Technologies, Inc.) stimulates a sacral nerve root (normally the S3 sacral nerve root) through an implantable pulse generator implanted ...

involves low-dose neural stimulation of the sacral nerve roots via permanently implanted electrodes placed through the sacral foramen at the level of S2 to S4. This expensive and invasive ...

In SNS, sacral nerve roots (S3 and S4) are permanently stimulated via a percutaneously implanted electrode. At first, the effect is reviewed using a test electrode and an external impulse ...

The sciatic nerve is formed from the nerve roots in the lumbar and sacral spine and extends through your hips and buttocks and down each leg. Often a bulging disc causes sciatica. Compression ...
