New Treatment Holds Promise for Patients With Spinal Cord Injuries

Wednesday, February 23rd, 2011

According to a recent article in Medical News Today, Functional Electrical Stimulation (FES) can significantly reduce disability caused by spinal cord injuries. The study was originally posted on line in the Journal of Neurorehabilitation and Neural Repair.

This relatively new treatment applies small electrical impulses to stimulate paralyzed muscles. The treatment has been shown to measurably improve a patient’s ability to pick up and hold objects. Dr. Popovic and his team concluded that FES should be used in conjunction with traditional physical therapy.

To see how this works, here’s an incredible demonstration by Children’s Hospital of an FES bicycle.

Here are some key facts about this study:

  • FES therapy uses low-intensity electrical pulses generated by a pocket-sized electric stimulator.
  • Unlike permanent FES systems, the one designed by Dr. Popovic and colleagues is for short-term treatment. The therapist uses the stimulator to make muscles move in a patient’s limb. The idea is that after many repetitions, the nervous system can ‘relearn’ the motion and eventually activate the muscles on its own, without the device.
  • The randomized trial, believed to be the first of its kind, involved 21 rehabilitation inpatients who could not grasp objects or perform many activities of daily living. All received conventional occupational therapy five days per week for eight weeks. However, one group (9 people) also received an hour of stimulation therapy daily, while another group (12 people) had an additional hour of conventional occupational therapy only.
  • Patients who received only occupational therapy saw a “gentle improvement” in their grasping ability, but the level of improvement achieved with stimulation therapy was at least three times greater using the Spinal Cord Independence Measure, which evaluates degree of disability in patients with spinal cord injury.
  • Based on their findings, the study’s authors recommend that stimulation therapy should be part of the therapeutic process for people with incomplete spinal cord injuries whose hand function is impaired.
  • Dr. Popovic’s team has almost completed a prototype of their stimulator, but need financial support to take it forward. Dr. Popovic thinks the device could be available to hospitals within a year of being funded.One limitation of the study is that the research team could not get all participants to take part in a six-month follow-up assessment. However, six individuals who received FES therapy were assessed six months after the study. All had better hand function after six months than on the day they were discharged from the study.
  • Dr. Popovic stresses that FES therapy should augment, and not replace, existing occupational therapy.
  • Another study, now underway, will determine whether stimulation therapy can improve grasping ability in people with chronic (long-term) incomplete spinal cord injuries.

If you or a loved one suffer from spinal cord injury, please consult with a physician about FES. In conjunction with physical therapy, this non-invasive medical procedure promises tremendous benefits to patients with spinal cord injuries.

New Microchip Promises to Make Life Much Easier for Paraplegic Patients

Friday, February 11th, 2011

Hope for those with paraplegia?

Researchers in the U.K. have developed a revolutionary microchip muscle stimulator that will enable patients with paraplegia to exercise multiple muscles at the same time. According to the Engineering and Physical Sciences Research Council (EPSRC), the microchip developed by Professor Andreas Demosthenous from University College of London and his team is truly unique.

The microchip chip is small enough (approximately the size of a child’s fingernail) that it can be implanted directly into the spinal canal. Unlike previous models, the new implant incorporates the muscle stimulator and the electrodes into a singular unit.  The unit is properly sealed to protect against moisture, which could lead to corrosion of the electrodes.

The creation of the implant has been made possible by new laser processing technology, which enabled researchers to micro-pack all components into one unit. With this new laser technology, researchers were able to cut much tinier electrodes from platinum. The electrodes are then folded into a 3D shape that resembles pages in a book. Each electrode can be wrapped around a nerve root. The electrode is then welded to the microchip located in the spinal cavity.

Because the implant comes with multiple electrodes, which can be connected to multiple nerve roots, it is capable of controlling entire muscle groups. In patients with paraplegia, the devise can be used to stimulate or trigger multiple paralyzed muscles at the same time. Researchers also claim that the new device will also be used in patients with bladder or bowel incontinence.  Because the device has multiple electrodes, some electrodes can be connected to nerve roots that control bladder muscles or nerves that control bowel capacity.

Although all of this may sound a bit scifi, the implant will be available for pilot studies sometime this year. If you or someone you know is paraplegic, this research is worth following. It clearly promises to offer life-chaining benefits to patients with paraplegia. If you know of other research on similar devices, we’d love for you to share that information with our readers. We’ll try to keep an eye on the progress and implementation of this device from the UK and keep you posted if and when developments occur.
