Brief summary

The goal of this clinical trial is to evaluate the clinical effectiveness of proprioceptive neuromuscular facilitation (PNF) combined with spiral muscle chain training in improving spinal function and posture in adolescents aged 13 to 18 years with spinal curvature abnormalities. The main questions it aims to answer are: Does exercise-based intervention improve trunk inclination angle, kyphotic angle, and body balance parameters in adolescents with spinal curvature abnormalities? Researchers will compare a PNF therapy group, a spiral muscle chain training group, and a combined PNF plus spiral muscle chain training group to assess differences in trunk inclination angle, kyphotic angle, and spinal mobility outcomes. Body mass index, fat-to-muscle ratio, and other body-composition-related indicators will be analyzed as exploratory post hoc outcomes. Participants will: Be assigned to one of three intervention groups: PNF therapy alone, spiral muscle chain training alone, or combined PNF plus spiral muscle chain training. Participate in supervised exercise training sessions three times per week for 12 weeks. Undergo pre- and post-intervention assessments, including body composition testing, and electronic spinal measurements.

Interventions

BEHAVIORALProprioceptive Neuromuscular Facilitation (PNF) Therapy

Proprioceptive neuromuscular facilitation (PNF) therapy is used as an exercise-based intervention to address abnormal spinal curvature in children with adolescent idiopathic scoliosis. The PNF program includes resisted scapular-pelvic patterns, cervical flexion and extension, trunk diagonal patterns (chopping and lifting), bilateral upper-limb diagonal patterns, and bridge exercises. Training sessions are supervised and conducted three times per week (every other day) for 12 weeks.

BEHAVIORALSpiral Muscle Chain (SPS) Training

Spiral muscle chain (SPS) training is applied as an exercise-based intervention aimed at improving spinal alignment, postural control, and neuromuscular coordination in children with adolescent idiopathic scoliosis. The SPS program consists of spiral stabilization exercises performed with elastic resistance, body positioning control, and stretching components according to a standardized training protocol. Training sessions are supervised and conducted three times per week (every other day) for 12 weeks.

BEHAVIORALCombined Exercise Therapy

The combined intervention integrates proprioceptive neuromuscular facilitation (PNF) therapy and spiral muscle chain (SPS) training as a comprehensive exercise program for children with adolescent idiopathic scoliosis. Participants perform both PNF and SPS exercise components within each training cycle to target spinal alignment, muscle endurance, and neuromuscular activation. Training sessions are supervised and conducted three times per week (every other day) for 12 weeks.

Design outcomes

Primary

MeasureTime frameDescription
Change in Trunk Tilt Angle (ATI)Baseline and after 12 weeks of interventionTrunk tilt angle (Angle of Trunk Rotation, ATI) measured using an electronic spine assessment device to evaluate changes in spinal asymmetry and trunk alignment.
Change in Kyphotic Angle (KA)Baseline and after 12 weeks of interventionKyphotic angle will be measured using an electronic spinal assessment device to evaluate changes in sagittal spinal curvature.
Change in Body Balance ParametersBaseline and after 12 weeks of interventionBody balance parameters assessed by electronic spine measurement, including head lateral deviation, shoulder asymmetry, and pelvic tilt.

Secondary

MeasureTime frameDescription
Change in Body Mass Index (BMI)Baseline and after 12 weeks of interventionBody mass index will be calculated from measured height and weight to evaluate changes in body composition and growth-related physical characteristics after the 12-week exercise intervention.
Change in Fat-to-Muscle Ratio (FMR)Baseline and after 12 weeks of interventionFat-to-muscle ratio will be derived from body composition testing to evaluate changes in the relative distribution of fat mass and muscle mass after the 12-week exercise intervention.
Change in Spinal MobilityBaseline and after 12 weeks of interventionSpinal mobility assessed by electronic spine measurement, including lateral flexion, flexion-extension, and rotational range of motion.
