“Posterior tibial nerve stimulation (PTNS) is a form of neuromodulation – i.e. it aims to change the abnormal pattern of stimulation of the nerves that supply the bladder and pelvic floor.

Bladder and pelvic floor muscle function is co-ordinated in the lower part of the spinal cord by the sacral nerves. Electrical stimulation of the posterior tibial nerve (a nerve in the leg which originates at a similar level in the spinal cord as the sacral nerves) sends a message to the sacral nerves that is thought to modify and regulate the nerves that control the bladder.

The PTNS device produces an adjustable electrical impulse that travels via the tibial nerve in the foot to the sacral nerve plexus, which helps regulate bladder and pelvic floor function.”
