Electroencephalographic Study of Schoolchildren with Adolescent Idiopathic Scoliosis

This study Investigated the possible pathologic electroencephalographlc (EEG) findings In scollotlc schoolchildren and their correlation to the degree and location of scollosls. Sixty-seven scollotlc, healthy schoolchildren were investigated and 42 nonscollotlc, healthy schoolchildren served as controls. In the group of sco-llotlcs the percentage of pathologic EEGs was higher than that of the control group (33% to 14%) P < 0.05, being much higher In the EEGs taken after activation (57% to 22%) P < 0.001. In the small curves, the percentage of pathologic EEGs was found to be higher only after activation In comparison with the percentage found In bigger curves, but without statistical significance. In lumbar, thoracolumbar, and double curves, focal EEG changes predominated. In contrast, in thoracic curves there was a higher Incidence of bilaterally synchronous discharges.
