Brain pathway anomalies in adolescent idiopathic scoliosis.

Objective: It was thought that sensory input, motor control or sensorimotor integration problems would cause spinal and postural balance problems in individuals with adolescent idiopathic scoliosis. For this reason, tractography of tractus corti-cospinalis (tr.CS) and lemniscus medialise (LM) in individuals with AIS and volume calculations of gyrus precentralis and gyrus postcentralis were performed. Methods: Brain diffusion tensor imaging was performed by including 30 right-handed Lenke Type-1 (right thoracic) female individuals with AIS and 27 healthy women (mean age 14.9 years) in the same age population. By analyzing the tr.CS and LM pathways of both groups with DSI Studio software; total fiber count, ratio to whole brain fiber count, average fiber length, fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD) and radial diffusivity (RD) values were calculated. Volume calculation was done with the mricloud program. Results: In the data we obtained, the total fiber number, average fiber length, fiber ratio and FA values in the tr. CS and LM of individuals with AIS were lower than the control group; MD, AD and RD parameters were found to be higher. In addition, the left and right tr. We determined that there were differences in total fiber number, average fiber length, fiber ratio, FA, MD, AD and RD parameters between tr.CS, LM, pathways. In terms of volume, the volumes of the left and right gyrus presentralis regions were in the control group; Although the left and right gyrus postrenralis were larger in the group with AIS, no significant difference was found between the groups. Conclusion: In individuals with AIS, especially the LM, which carries the proprioceptive sense, and tr, which is responsible for the somatomotor system. The low number of tr. CS fibers and low fiber ratio indicate that it may be associated with postural balance and spinal curvature problems seen in AIS. [ABSTRACT FROM AUTHOR]
