Technology Overview

There are many areas of neurotechnology in the treatment of pain. This is an overview of three basic areas of treatment that are currently available;

  • Transcutaneous electrical nerve stimulation (TENS) or percutaneous neuromodulation units (PENS),
  • Implanted drug delivery systems (IDDS)
  • Spinal cord stimulators (SCS).

  1. TENS units (transcutaneous electrical nerve stimulation) and Percutaneous Neuromodulation Units (PENS) work by delivering low level electrical stimulation through electrodes placed directly on the skin of the affected area. The electrical stimulation delivered through the skin may help alleviate pain by blocking pain messages being sent to the brain. Both systems require a physician prescription but this therapy can provide a convenient means of treating some forms of pain. Both are non-invasive and can be an economical solution.
  2. Implanted Drug Delivery Systems (IDDS), also known as Intrathecal Analgesia Therapy, refers to the administration of medicine, either pain-relieving or spasticity-relieving, such as baclofen, by a medication delivery pump. The IDDS include a chamber or reservoir for the drug that delivers the medication through a catheter directly into the spinal canal (intrathecal). The pump needs to be refilled, usually once every few months, by placing a needle through the skin. This procedure is typically performed on an outpatient basis or during a regular doctor’s visit. Generally, a person first undergoes a trial of the medication by an intrathecal injection. If successful, a pump system can be implanted permanently through a surgical procedure. IDDS reduce the need for oral medications, can be more effective and is now a mainstay of therapy for intractable pain including neuropathic pain and spasticity.
  3. Spinal Cord Stimulation (SCS) system is a hybrid system comprised of implanted electrodes in the spine and an external control unit. It uses electrical stimulation to block the pain pathways to the brain that travel through the spinal cord. SCS has also been known to decrease spasticity. An initial trial is needed to see if effective results can be achieved. If the trial is successful, a permanent system may be implanted. The user has the ability to keep the system on permanently or as needed. Find a SCS specialist in your area is provided by our partner, Neuromodec, click here to search.

These above options should be discussed with a medical professional trained in interventional pain medicine. Deep brain stimulation, transcranial magnetic stimulation and the use of very high frequency alternating currents as a method for blocking nerve conduction in peripheral nerves is currently under investigation. These methods might be able to provide an improved alternative for blocking pain and controlling muscle spasms. To discover more about available clinical trials, visit

Technology Listing

There are a variety of applications which are listed below by category. Prior to considering any new therapy, treatment or device, a proper evaluation should be conducted with a knowledgeable medical professional. There are health, medical and financial risks. Out of pocket costs and available insurance coverage for any treatment must be considered prior to starting a protocol. Also, it is key to understand that results and applications will vary depended on symptom and function limitations related to the condition. If you find something of interest, please contact the vendor directly to find a trained professional in your area.
