Abstract

Study Design Cross-sectional Study.

Background Itisnotyetclearwhetherthelossofproprioceptivesensationandmuscleweaknessseeninadolescentidio-

pathic scoliosis (AIS) is the result of central nervous system dysfunction or secondary to spinal deformity. In our study, in

ordertofindananswertothisquestion,weexaminedthemicroarchitectureofthenervustrigeminus,whichisleastaffected

byspinaldeformityandcontainsbothproprioceptivesensoryandmotorfibers.

Methods Inthissingle-center,cross-sectionalcohortstudy,40LenkeType3(27female,13male)AISpatientsand40(25

female,15male)healthyindividualsbetweentheagesof10–18years.Tractographyofthenervustrigenimuswasperformed

using the “DSI Studio” program. The volumes of the targeted musculus pterygoideus lateralis and musculus pterygoideus

medialis were measured using the Insight Segmentation and Registration Tool Kit (ITK -SNAP) program. The data were

evaluatedusingtheStatisticalPackagefortheSocialSciences22.0programforWindows.

Results Therewasnosignificantdifferencebetweenthetwogroupsintermsofbaselinecharacteristics(p˃0.05).Leftner-

vustrigeminusfibernumberandfiberratioweresignificantlyhigherinthecontrolgroupcomparedtothescoliosisgroup

p <0.05.Rightandleftlateralpterygoidmuscleshowedlowervolumeandvolumepercentageinthescoliosisgroupcom-

pared to the control group (p <0.05).

Conclusion According to the study data, proprioceptive sensory and motor control dysfunction in AIS is predicted to develop

independently of spinal deformity.
