Neuromodulation

Neuromodulation treatments are relatively safe procedures. The large majority of complications are non-life-threatening events related to failure of the device. For example, there is a risk that the electrode(s) could move from the intended location, malfunction or break.

If any of these incidents occur, our specialist teams will be on hand to offer support and assistance. Special computer hardware is used to check the device faults and then specific action is taken according to the problem.

Devices are designed to last many years but will need regular maintenance depending on the system used. Specialist teams will be able to advice of these specific requirements and of the battery life.

Other general risks of neuromodulation include:

• Wearing off of the pain relief (over months to years after the system is inserted)
• Failure of the system to treat the pain
• Damage to nearby structures in the body during placement of the electrodes
• Infection at the insertion site
• Pain at the insertion site.

As with any procedure, neuromodulation procedures carry a very small risk of more serious complications. These are very rare but the specialist doctor will discuss these comprehensively prior to the procedure.

Serious complications of neuromodulation can include:

• Neurological injury either from the needle puncture, lead placement or during the procedure. This can result in loss of function, power or a sensation of numbness
• Puncture of the protective layer around the spinal cord (dura), which may cause a severe headache. This may require a further procedure with a spinal injection

These are very rare and thought to affect around two patients in a million.
