A new study has found that high-frequency spinal cord stimulation significantly reduces muscle spasticity in patients with incomplete spinal cord injuries, allowing for more effective rehabilitation.
Key Findings:
- High-frequency electrical stimulation blocks abnormal muscle contractions, improving mobility.
- When combined with traditional low-frequency stimulation, this technique effectively reduces muscle stiffness and spasms during rehabilitation.
- Early clinical trials show promising results, though further research is needed to confirm long-term benefits.
Conducted by researchers from EPFL, Università San Raffaele, and Scuola Sant’Anna, the study reveals that high-frequency stimulation can safely inhibit overactive spinal circuits, which contribute to muscle spasticity in nearly 70% of spinal cord injury patients. By targeting sensory neurons in the spinal cord, this approach indirectly regulates motor function, allowing paralyzed patients to participate in rehabilitation programs previously inaccessible to them.
The findings, published in Science Translational Medicine, highlight the potential of this minimally invasive technique in treating severe spinal cord damage. While clinical trials have shown encouraging results in reducing muscle stiffness and spasms, further studies are needed to fully understand its long-term impact.
