Patients

Q1 What conditions are neuromodulation techniques used to treat?
Neuromodulation is used to treat and enhance quality of life in individuals who suffer severe chronic illness due to persistent pain, spasticity, movement disorders, epilepsy, ischaemia, cardiac, bowel and bladder dysfunction, spinal injury, visual, auditory and specific psychiatric disorders.

The most common treatment is spinal cord stimulation and the most common indication is the persistent severe neuropathic pain found in those who have had technically successful spinal decompression surgery, but who have had recurrence or persistence of symptoms.

Q2 What is the procedure for patient assessment prior to implant?
The decision to provide a neuromodulation therapy is taken after careful consideration with you, your implanting doctor and the neuromodulation team. It is neither a treatment of first nor last resort. If symptoms can be managed effectively and simply using other methods then these are considered first.

Often your doctor will recommend that you see several other professionals in the multidisciplinary team before agreeing to do a neuromodulation treatment, in order to be really sure that this is the best treatment at the best time for you, and to decide if any additional therapy is required.

Q3 What is involved in the neuromodulation implant procedure?
Clearly the implant procedure is different depending upon the actual procedure done and by whom. Quite often the electrodes or catheters are placed under local anaesthetic.

Q4 What questions does the INS suggest I ask my implanting doctor?
You should ask your doctor about the neuromodulation treatment selected and whether there are any simpler alternatives or solutions to your problem. There will be advantages and disadvantages to any treatment, but it is important you should know as much as possible. You should ask about their track record with the treatment and what their rate of common complications is. You should ask who will be your long term contact in the neuromodulation team.

Q5 What are the side effects of these treatments?
There are complications that are general to any implant into the body and complications that are specific to the technique, therapy and disease. You should ask your doctor and the implanting team all about any common or dangerous possible side effects before embarking on this or any treatment. Further information on complications specific to the device, technique and therapy can be found from the manufacturers’ own websites.

Q6 If I undergo treatment, how long will it take me to recover and how long will I be off work?
The amount of time required off work following these treatments will depend upon several factors, and it would be best to check with the neuromodulation team.

Q7 Will my body reject the device after it is implanted?
The devices are made of materials that are usually well tolerated by the body. True rejection is extremely rare.

Q8 How long will the device need to be in me?
Due to the nature of your symptoms it is more than likely that you have a permanent condition. Thus, neuromodulation is usually embarked upon with the expectation that the system will be required long term. The simplest answer is to say for as long as you need it. However, the device can be removed.

Q9 What happens if the device breaks down?
Your implant team would need to be contacted. The problem can usually be diagnosed after asking you some questions and by interrogating the device with the master computer. Further action can then be advised.

Q10 How often will the device need to be replaced?
There are several components to the neuromodulation device. For advice on battery life please see question 12. Owing to the fact that these are mechanical devices there is a requirement for maintenance, as one might expect.

Q11 How is the device regulated once it has been implanted?

The fully implanted stimulator systems can be programmed using telemetry by your doctor’s programmer. Most of the newer devices will be issued with a patient programmer so that you will be able to not only turn it on and off but also make your own adjustments to the stimulation. The drug delivery systems will be adjusted if required by your doctor.

Q12 How long does the battery last?
Please also refer to the individual manufacturers’ websites.

There are now three ways that the stimulating devices are powered.

The newest devices are rechargeable systems. Longevity varies from nine years to more depending upon manufacturer and usage.

A commonly used system has an internal non-rechargeable battery which comes in various sizes.

Once this is exhausted the whole implantable pulse generator which includes the battery (IPG) is replaced. The longevity is variable. Typically we would expect an IPG to last between two and seven years depending upon size, manufacturer and usage.

The original systems, which may sometimes still be used in certain instances, are those powered by radiofrequency coupling, whereby power is transmitted continuously through the skin to the device from an external transmitter stuck to the surface of the skin. Typically these devices might last 7 years or more.

Some drug delivery pumps are powered electrically with an internal battery and may last seven to 10 years depending on manufacturer. Other pumps are constant flow rate and gas driven. The hydraulic pressure in the gas when compressed at refill powers the constant flow rate. These pumps may last longer than 10 years.

Medical Professionals

Q1 What conditions are neuromodulation techniques used to treat?
Neuromodulation is used to treat and enhance quality of life in individuals who suffer severe chronic illness due to persistent pain, spasticity, movement disorders, epilepsy, ischaemia, cardiac, bowel and bladder dysfunction, spinal injury, visual, auditory and specific psychiatric disorders.

The most common treatment is spinal cord stimulation; and the most common indication is the persistent severe neuropathic pain found in those who have had technically successful spinal decompression surgery, but who have had recurrence or persistence of symptoms.

Q2 Where is the evidence base to support neuromodulation?
The scientific community members who are involved with neuromodulation have recognised the need to produce high quality evidence of clinical efficacy. Considering the difficulties in performing randomised controlled trials with surgical techniques much has been achieved, such as SCS for angina pectoris, critical limb ischaemia, complex regional pain syndrome and neuropathic failed back surgery syndrome. Similar quality has been achieved with sacral nerve stimulation for faecal and urinary incontinence, intrathecal baclofen in spasticity, intrathecal opioids in cancer pain and vagal nerve stimulation in epilepsy, and cochlear implantations.

Q3 What is the procedure for patient assessment prior to implant?
The decision to provide a neuromodulation therapy is taken after careful consideration with the patient, the implanting doctor and the neuromodulation team. It is neither a treatment of first nor last resort. If symptoms can be managed effectively and simply using other methods then these are considered first.

Q4 What is involved in the neuromodulation implant procedure?
Clearly the implant procedure is different depending upon the actual procedure done and by whom. Quite often the electrodes or catheters are placed under local anaesthetic. Other parts of the procedures can be more satisfactorily done under general anaesthesia.

Q5 How do I decide if neuromodulation is the best treatment for my patient?
There are many different indications for neuromodulation. All are agreed that these therapies fulfil the needs of patients at the niche end of a spectrum of disease severity and impact. However as good quality research trials accrue it becomes more likely that these therapies will be introduced earlier in traditional chronic disease management. Neuromodulation should be considered as part of a portfolio of management strategies and selected after multidisciplinary consideration and expert application and support.

Q6 What complications are associated with neuromodulation techniques?
There are complications that are general to any implant into the body and complications that are specific to the technique, therapy and disease. Each implanting centre will be monitoring these and should be able to quote their current rates of complication.

The weaker parts of the systems used tend to be the electrodes, catheters and connections. INS members are working hard with industry to improve design, and system durability.

Complications specific to the devices, technique and therapy can be found from the manufacturers’ own websites.

Q7 What are the costs and cost-effectiveness of neuromodulation?
There are several costs of the procedures to be considered. These are implant components, professional fees, operating room and hospitalisation costs. Cost effectiveness of the procedure is a method by which the total costs of the procedure as well as the change in healthcare costs following the procedure are compared with the costs of not providing the treatment. Various cost analyses have been done for some of the neuromodulation procedures for some of the indications. For example, SCS appears to become cost effective between 2 and 2.5 years after treatment in patients with angina pectoris, failed back surgery syndrome and complex regional pain syndrome.

Q8 Where is my nearest INS member’s clinic?
Those members that have indicated that they wish their clinic contact details to be made available can be contacted via the INS website or national chapter website.

Q9 I need to do further research in this area before I recommend a patient for neuromodulation. Where do you suggest I look?
There is a useful bibliography in this website which although not exhaustive, is a list of some of the more influential and well-received publications. Explanatory content on our therapies page often includes specific citations and references; as does material gathered on our overview page for medical providers. Also, texts and additional resources are listed on our links page. Finally, the end of the therapies page also lists evidence tables about investigational deep brain stimulation studies in certain behavioral or psychiatric conditions.
