Brief summary

The goal of this clinical trial is to evaluate the effects of scoliosis-specific three-dimensional exercises combined with pelvic floor muscle training on scoliosis severity and spinopelvic parameters in adolescents with idiopathic scoliosis. The main questions it aims to answer are: * Does the addition of pelvic floor muscle training to scoliosis-specific three-dimensional exercises improve scoliosis severity compared with scoliosis-specific three-dimensional exercises alone? * Does the addition of pelvic floor muscle training improve spinopelvic parameters compared with scoliosis-specific three-dimensional exercises alone? Researchers will compare a scoliosis-specific three-dimensional exercise plus pelvic floor muscle training group with a scoliosis-specific three-dimensional exercise group to determine whether the combined intervention provides additional clinical benefits. Participants will: * undergo baseline clinical and radiographic assessments; * be randomly assigned to one of the two intervention groups; * receive supervised treatment for 3 months according to the assigned intervention; * undergo follow-up clinical and radiographic assessments at the end of the intervention period.

Detailed description

Adolescent idiopathic scoliosis (AIS) is a three-dimensional spinal deformity characterized by lateral curvature of the spine, vertebral rotation, and alterations in sagittal alignment. Conservative treatment, including scoliosis-specific three-dimensional exercises, is widely recommended for individuals with mild to moderate AIS to reduce curve progression and improve postural alignment and function. The pelvic floor muscles contribute to lumbopelvic stability through their interaction with the diaphragm, abdominal muscles, and paraspinal muscles. Although alterations in trunk muscle function have been reported in individuals with AIS, the potential role of pelvic floor muscle training as an adjunct to scoliosis-specific exercise programs has not been adequately investigated. This randomized controlled trial will compare scoliosis-specific three-dimensional exercises combined with pelvic floor muscle training versus scoliosis-specific three-dimensional exercises alone in adolescents with idiopathic scoliosis. The study will evaluate the effects of these interventions on scoliosis severity and spinopelvic parameters after a 3-month treatment period. The findings may contribute to optimizing conservative rehabilitation strategies for adolescents with idiopathic scoliosis.

Interventions

BEHAVIORALScoliosis-Specific Three-Dimensional Exercise

Supervised scoliosis-specific three-dimensional exercises administered twice weekly for 3 months, with additional home exercises according to the study protocol.

BEHAVIORALPelvic Floor Muscle Training

Supervised pelvic floor muscle training performed in combination with scoliosis-specific three-dimensional exercises twice weekly for 3 months, with additional home exercises according to the study protocol.

Masking description

Outcome assessors were blinded to participants' group allocation throughout the study to minimize assessment bias.

Intervention model description

Participants were randomly assigned to one of two parallel intervention groups. One group received scoliosis-specific three-dimensional exercises, while the other received scoliosis-specific three-dimensional exercises combined with pelvic floor muscle training. Both interventions were administered over a 3-month period, and outcomes were assessed before and after treatment.

Design outcomes

Primary

MeasureTime frameDescription
Cobb AngleBaseline and 3 monthsChange in Cobb angle measured on standing posteroanterior spinal radiographs using the Cobb method.

Secondary

MeasureTime frameDescription
Angle of Trunk RotationBaseline and 3 monthsChange in angle of trunk rotation measured in degrees using a Baseline® scoliometer during the Adams forward bend test. Thoracic and lumbar measurements will be recorded where applicable.
Apical Vertebral RotationBaseline and 3 monthsChange in apical vertebral rotation measured in degrees on spinal radiographs using the Raimondi method.
Pelvic ParametersBaseline and 3 monthsChanges in pelvic incidence (PI), pelvic tilt (PT), and sacral slope (SS) measured on standing lateral spinal radiographs. Pelvic incidence is defined as the angle between the line perpendicular to the sacral endplate and the line connecting the center of the sacral endplate to the femoral head axis. Pelvic tilt is defined as the angle between the vertical line and the line connecting the center of the sacral endplate to the femoral head axis. Sacral slope is defined as the angle between the sacral endplate and the horizontal plane. All parameters are measured in degrees.
Pelvic Floor Muscle ActivityBaseline and 3 monthsChange in pelvic floor muscle activity assessed using surface electromyography. Pelvic floor muscle activation during contraction and resting periods will be recorded according to the study assessment protocol. Higher activation values indicate greater pelvic floor muscle activity.
Sagittal Spinal Alignment ParametersBaseline and 3 monthsChanges in thoracic kyphosis (T3-T12 Cobb angle), lumbar lordosis (L1-S1 Cobb angle), cervical lordosis (C2-C7 Cobb angle), and sagittal vertical axis (SVA) measured on standing lateral spinal radiographs. Thoracic kyphosis, lumbar lordosis, and cervical lordosis are measured in degrees using the Cobb method. Sagittal vertical axis is measured as the horizontal distance between the C7 plumb line and the posterosuperior corner of S1 and is reported in millimeters.
