Study Reveals Spinal Cord Injuries Disrupt Muscle Signal Coordination

Summary

Story summary

Researchers at KTH Royal Institute of Technology found that the nervous system's ability to send smooth signals to muscles is impaired after spinal cord injury.
The study, published in the Journal of NeuroEngineering and Rehabilitation, involved 15 spinal cord injury patients and 10 healthy individuals.
At low exertion, spinal cord injury patients showed uncoordinated muscle movements.
At higher exertion, the nervous system overcompensated, producing less precise signals.
