Adolescent idiopathic scoliosis (AIS) is a structural,
lateral curvature with rotation of the spine that develops around puberty. The
influence of this spinal deformity on three-dimensional trunk movements during
gait has not yet been elucidated. The aim of this study was to determine the
influence of spinal curve pattern (single thoracic curve vs. single lumbar curve)
on trunk kinematics during gait. METHODS: Twenty-two patients with a single
thoracic curve (Lenke type 1) and 17 patients with a single lumbar curve (Lenke
type 5) were included in this study. Trunk symmetry in the sagittal, coronal, and
transverse planes during gait was evaluated using an optoelectronic motion
capture system. RESULTS: In the type 1 group, the trunk was significantly rotated
towards the concave side in the transverse plane during gait (mean difference of
transverse rotation angle between concave side load and the convex side load,
8.8+/-0.6 degrees , p<0.01). In the type 5 group, the trunk was significantly
rotated towards the convex side in the coronal plane throughout the stance phase
of gait (mean difference of coronal inclination angle, 1.9+/-0.3 degrees , p<0.05). CONCLUSIONS:
The AIS patients with a single thoracic curve showed
asymmetrical trunk movement in the transverse plane, and patients with a single
lumbar curve showed asymmetrical trunk movement in the coronal plane. These
results indicate that the spinal curve pattern influenced trunk kinematics, and
suggest that the global postural control strategy of patients with AIS differs
according to the curve pattern.
