Surgically implanted sacral nerve stimulation may be more effective than exercises, and electrical stimulation and biofeedback may be more effective than exercises or electrical stimulation by themselves.
22.
The anterior division of the third sacral nerve divides into an upper and a lower branch, the former entering the sacral plexus and the latter the pudendal plexus.
23.
Sciatica is generally caused by the compression of lumbar nerves L4, or L5 or sacral nerves S1, S2, or S3, or by compression of the sciatic nerve itself.
24.
Medtronic Corp .'s " sacral nerve stimulator " requires major surgery, so it is intended for patients who get no relief from drugs or diet, the FDA warned.
25.
In most studies, usually 5-10 % of subjects need post-operative correction to lead migration, but since leads can be anchored near the sacral nerve, subsequent operations are generally unnecessary.
26.
It typically involves the implantation of a programmable stimulator subcutaneously, which delivers low amplitude electrical stimulation via a lead to the sacral nerve, usually accessed via the S3 foramen.
27.
The sacral nerves have both afferent and efferent fibers, thus they are responsible for part of the sensory perception and the movements of the lower extremities of the human body.
28.
The U . S . Food and Drug Administration has approved InterStim Therapy, by Medtronic, as a sacral nerve stimulator for treatment of urinary incontinence, high urinary frequency and urinary retention.
29.
Unlike existing treatments for the condition, Medtronic's device works by stimulating the sacral nerve system-- located at the base of the spine and responsible for controlling the bladder, sphincter and pelvic floor.
30.
From the pelvis, the anterior primary branches of the nerves entering the plexus ( the first sacral nerve being a particularly large one ) and a mass of nerves on the piriformis can be recognized.
