First-of-its-kind study shows benefits of electrical stimulation therapy for people paralyzed by spinal cord injury

18.02.2011
Findings have implications for quality of life and independence

A new treatment approach which uses tiny bursts of electricity to reawaken paralyzed muscles “significantly” reduced disability and improved grasping ability in people with incomplete spinal cord injuries, according to results published today.

In a study posted online in the journal Neurorehabilitation and Neural Repair, Toronto researchers report that functional electrical stimulation (FEFirst-of-its-kind study shows benefits of electrical stimulation therapy for people paralyzed by spinal cord injuryS) therapy worked considerably better than conventional occupational therapy alone to increase patients’ ability to pick up and hold objects.

Core News Facts

· 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.

“This study proves that by stimulating peripheral nerves and muscles, you can actually ‘retrain’ the brain,” says the study’s lead author, Dr. Milos R. Popovic, a Senior Scientist at Toronto Rehab and head of the Rehabilitation Engineering Laboratory. “A few years ago, we did not believe this was possible.”

“FES (stimulation therapy) has the potential to have a significant and positive impact on the lives of individuals living with the devastating results of spinal cord injury,” says Dr. Anthony Burns, Medical Director of Toronto Rehab’s spinal cord rehabilitation program.

“The trial is “groundbreaking,” says Dr. Burns who will work with Dr. Popovic, “to make this intervention available to our patients, and to answer important questions such as the duration of the effect.”

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
