Electroencephalographic predictors of neuropathic pain in subacute spinal cord injury
The Journal of Pain May 15, 2018
Vuckovic A, et al. - Researchers sought to illustrate that in people with subacute spinal cord injury (SCI), neuropathic pain (NP) has distinguishing electroencephalographic (EEG) markers which come before the onset of pain. In a relaxed state and during motor imagination tasks, EEG was recorded in 10 able bodied participants and 31 subacute SCI participants (11 with NP, 10 without NP, and 10 who developed pain within 6 months of EEG recording). Outcomes indicated that, in SCI, NP has both EEG predictors and early markers. Predictors of NP in SCI included reduced EEG reactivity to eyes opening and reduced alpha power. Compared to sensory tests, EEG predictors could predict NP earlier.
