Tibial Nerve Neuromodulation – For the Treatment Of Urinary Disorders, Faecal Incontinence, Constipation, Pelvic Floor Disorders and Pain

  • Reference Number: HEY-305/2016
  • Departments: GI Physiology


This leaflet has been produced to give you general information about your procedure. Most of your questions should have been answered by this leaflet. It is not intended to replace the discussion between you and your doctor, but may act as a starting point for discussion.  If after reading it you have any concerns or require further explanation, please discuss this with a member of the healthcare team caring for you.

What is tibial neuromodulation?

You have probably been troubled by difficulty going to the toilet, faecal incontinence, constipation, urinary or pelvic floor disorders. Following discussion with your healthcare professional they have suggested tibial nerve neuromodulation may be a realistic treatment option for you.

Neuromodulation is the use of low voltage electricity to make nerves work better. The tibial nerve is involved with the workings of the pelvic floor and anus. By neuromodulating this nerve, the bowel and bladder can work better.

A small slim needle electrode, similar to an acupuncture needle, is temporarily inserted near your ankle. The needle electrode is then connected to a battery powered neuromodulator which is placed next to the ankle. The neuromodulator is then turned on and adjusted according to your own response.

Each treatment is approximately 30 minutes and takes place in the hospital. There is an initial series of 12 weekly treatments, after which your response to these treatments will be discussed. If successful, further treatments to maintain your results will be required.

Why do I need tibial nerve neuromodulation?

Tibial nerve neuromodulation is offered to people who have faecal incontinence/urgency and urinary symptoms. This is often when other medical or surgical procedures have not worked. By using neuromodulation to the tibial nerve, the function of the anus, bladder and pelvic floor may be improved and therefore improving symptoms.

Can there be any complications or risks?

The main risks associated with this procedure are related to the needle or mild electrical current used. Discomfort, pain, redness or numbness may be experienced around the needle insertion site. There may be minor bleeding on withdrawal of the needle. These symptoms if experienced should be short lived.

While neuromodulation of nerves is an established and safe procedure, stimulation of the tibial nerve in this way is relatively new. There may be other risks and side effects that are not known. This information sheet will be updated if new complications or risks occur.

How do I prepare for tibial nerve neuromodulation?

Please read the information leaflet. Share the information it contains with your partner and family (if you wish) so that they can be of help and support. There may be information they need to know, especially if they are taking care of you following this procedure.

Prior to the procedure you can eat and drink as normal. You will be able to drive and go back to normal activities once the procedure is over. Medication does not need to be stopped prior to this procedure.

What will happen?

You will be seen in the Department of GI Physiology. You will be seen by one of the team who will explain the procedure to you once more. You do not need to undress but we will need access to your bare feet and ankles. One of your ankles will be selected and the procedure will commence.

General Advice and Consent

Most of your questions should have been answered by this leaflet, but remember that this is only a starting point for discussion with the healthcare team.

Consent to treatment

Before any doctor, nurse or therapist examines or treats you, they must seek your consent or permission. In order to make a decision, you need to have information from health professionals about the treatment or investigation which is being offered to you. You should always ask them more questions if you do not understand or if you want more information.

The information you receive should be about your condition, the alternatives available to you, and whether it carries risks as well as the benefits. What is important is that your consent is genuine or valid. That means:

  • you must be able to give your consent
  • you must be given enough information to enable you to make a decision
  • you must be acting under your own free will and not under the strong influence of another person
