[′sak·rəl ′nərv]

Any of five pairs of spinal nerves in the sacral region which innervate muscles and skin of the lower back, lower extremities, and perineum, and branches to the hypogastric and pelvic plexuses.

An electrode sits against the sacral nerves and delivers mild electrical pulses to retrain the bladder control nerves.

Sagittal and axial plane magnetic resonance imaging (MRI) revealed that sacral nerves were compressed by the angulated sacral vertebral body and lamina on T2-weighted images (Figures 1(c) and 1(d)).
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.
Sacral nerve stimulation using a surgically implanted device can significantly curb urinary urge incontinence in patients refractory to standard medical therapy.
Elkelini and colleagues describe a rodent model that incorporates a novel transdermal amplitude-modulated signal (TAMS) as a non-invasive alternative to an implantable SNM to treat neurogenic detrusor overactivity.[sup.13] The results appear to demonstrate that the amplitude-modulated waveform is sufficient to overcome skin and tissue impedance and stimulate the sacral nerves. The authors demonstrate a decrease in the calcitonin gene-related protein (CGRP) concentration with neurostimulation and significant lowering of the cystometrogram threshold pressure (p = 0.02).
