Revolutionizing Spinal Cord Injury Rehabilitation: High-Frequency Electrical Stimulation Shows promise
Research has unveiled an innovative method that could transform the lives of rehabilitation-mayo-clinic/sections/overview/ovc-20480640″ title=”Spinal Cord Injury Rehabilitation Program – Mayo Clinic”>spinal cord injury patients, potentially helping them regain the ability to walk. Recent study published in Science Translational Medicine presents high-frequency electrical stimulation as a promising solution for managing spasticity, a frequent complication affecting nearly 70% of all spinal cord injury patients.
Spasticity, marked by unpredictable and involuntary muscle stiffness, poses a significant challenge to conventional rehabilitation methods, including traditional electrical stimulation of the spinal cord. A team of researchers, led by Silicon Micera from EPFL’s Neuro X Institute and Scuola Sant’Anna, has discovered that high-frequency spinal cord stimulation can effectively tackle spasticity and open doors to new rehabilitation protocols.
"High-frequency stimulation of the spinal cord, combined with conventional low-frequency stimulation, has been shown to be effective in managing spasticity and helping patients move during spinal cord injury rehabilitation," explains Professor Micera.
Historically, electrical stimulation of the spinal cord was primarily used to bypass damaged nerves and trigger muscle movement. However, spinal cord injuries often leave the motor control centers in the brain disconnected from the spinal cord, making voluntary muscle control challenging.
The high-frequency technique, akin to a ‘kilohertz block’ of motor circuits, has been shown to prevent muscle spasms and provide a smoother pathway for rehabilitation. Clinical trials conducted at San Raffaele Hospital on patients with partial spinal cord injuries have demonstrated promising results, with further research underway to solidify its potential (watch the video below).

"Our clinical data from these two patients suggests that high-frequency stimulation could be beneficial for reducing muscle stiffness and spasms in paralysis. More experiments are needed to confirm this approach’s potential," concludes Professor Marco-Mortini.
The progress in high-frequency stimulation comes alongside advancements like the MARCH project in the Netherlands, which aims to develop wearable exoskeletons to aid locomotion in spinal cord injury patients.
While this innovation holds great promise, it’s essential to remember that each patient’s journey is unique and personalized care is crucial. The integration of high-frequency spinal cord stimulation into rehabilitation protocols represents a significant stride towards restoring physical independence for many spinal cord injury patients.
