Electroencephalography and Electromyography as a Non-Invasive Biomarker of Neural Regeneration: A Review of Central and Peripheral Nervous System Injury and Regeneration
Using brain and muscle electrical signals to track nerve healing after injury
Brain waves (EEG) and muscle signals (EMG) can monitor whether nerves are actually healing after injury, offering doctors a non-invasive way to track recovery in real time. The two measurements work together: EEG reveals how the brain is reorganizing after damage, while EMG shows whether muscles are regaining function as peripheral nerves reconnect.
Nerve injuries from stroke or spinal cord damage are hard to assess — doctors can't easily tell if healing is happening without invasive procedures. Being able to track recovery with simple electrical readings from skin electrodes would let clinicians adjust treatment earlier, predict which patients will recover function, and measure whether new therapies actually work. This bridges the gap between understanding what's happening at the molecular level and knowing whether patients are actually getting better.
