Background and Aims: Major thoracic scoliosis is the most prevalent form of scoliosis, which may appear with or without a compensatory deviation of the pelvis. The impact of this pelvis malalignment on lower limb kinetics in landing and jump has not been thoroughly explored. This study aimed to investigate the lower limb joints’ moments and powers in two groups of adolescents with major thoracic scoliosis: those with a pelvis compensatory deviation and those without, during a stop-jump task.
Materials and Methods: We recruited 12 patients with major thoracic curvature exhibiting a compensatory deviation of the pelvis and 12 patients without such a deviation. Using two force plates and an 8-camera motion capture system, we quantified the moments and powers of the hip, knee, and ankle joints during stop-jump tasks. Data processing and calculations were performed using Visual-3D and MATLAB software. The time series of the variables were compared between the two groups using the SPM{t} method, with a significance level set at 0.05.
Results: In both groups, the hip extensor moment explored the greatest moment, while the knee joint showed the smallest moment (abductor). Absorbed and produced power was highest at the sagittal plane of hip joint. Both groups demonstrated symmetrical moments and powers, with no significant difference observed in the kinetics of the lower limb joints between the two groups (p>0.05).
Conclusion: The presence of pelvis compensatory deviation in AIS patients with major thoracic curvature does not significantly influence lower limb movement patterns or kinetics during stop-jump. Both groups exhibited comparable patterns of joint moments and powers, suggesting that compensatory pelvic adjustments may not play a critical role in lower limb kinetics in this context.
