The Effects of Lumbopelvic Rhythm on Postural Control, Daily Activities, and Quality of Life in Individuals With AIS

Adolescent idiopathic scoliosis (AIS) leads to three-dimensional spinal deformity during adolescence, causing deviations in the frontal, sagittal, and axial planes, impairing physical function, balance, and lumbopelvic rhythm. Individuals with AIS exhibit decreased trunk movement, muscle overactivation, increased energy expenditure, balance/gait disturbances, and abnormalities in proprioceptive/vestibular input; pressure center deviations increase in postural control. These changes negatively impact daily life, pain, and quality of life. Although the literature has examined the relationships between AIS and muscle activation, range of motion, pelvic position, and gait/balance, the relationship between lumbopelvic rhythm changes and curve type/localization/severity, and its impact on postural control and quality of life, has not been investigated. This study aims to elucidate movement patterns by evaluating lumbopelvic rhythm in individuals with AIS and to guide clinical diagnosis/treatment.
