Brief Summary

The goal of this clinical trial is to evaluate the clinical effectiveness of proprioceptive neuromuscular facilitation (PNF) combined with spiral muscle chain (SPS) training in improving spinal function and posture in children with adolescent idiopathic scoliosis. The main questions it aims to answer are: Does PNF combined with SPS training improve trunk alignment and body balance parameters in children with mild adolescent idiopathic scoliosis? Does the combined intervention improve spinal mobility and paraspinal muscle endurance compared with single-intervention approaches? Does the combined intervention lead to favorable changes in surface electromyography (sEMG) indicators of trunk and paraspinal muscles? Researchers will compare a PNF therapy group, an SPS training group, and a combined PNF + SPS group to assess differences in spinal alignment, muscle endurance, and neuromuscular activation outcomes. Participants will: Be assigned to one of three intervention groups: PNF therapy alone, SPS training alone, or combined PNF and SPS training Participate in supervised exercise training sessions three times per week for 12 weeks Undergo pre- and post-intervention assessments, including electronic spinal measurements and surface electromyography testing

Study Arms (3)

Proprioceptive Neuromuscular Facilitation (PNF) Therapy

EXPERIMENTAL

Participants receive proprioceptive neuromuscular facilitation (PNF) therapy as an exercise intervention for abnormal spinal curvature. Training is conducted 3 times per week (every other day) for 12 weeks. The PNF protocol includes resisted scapular-pelvic patterns, cervical flexion/extension, trunk chopping/lifting patterns, bilateral upper-limb patterns, and bridge exercises (per PNF schedule).

Behavioral: Proprioceptive Neuromuscular Facilitation (PNF) Therapy

Spiral Muscle Chain (SPS) Training

EXPERIMENTAL

Participants receive spiral stabilizing muscle chain (SPS) training as an exercise intervention for abnormal spinal curvature. Training is conducted 3 times per week (every other day) for 12 weeks. The SPS program follows the SPS training schedule (Training 1A-6A, 7C-10C, and stretching component), with planned repetitions/sets and practice time as listed in the protocol schedule.

Behavioral: Spiral Muscle Chain (SPS) Training

Combined Exercise Therapy

EXPERIMENTAL

Participants receive a combined program consisting of PNF therapy plus SPS spiral muscle chain training as an exercise intervention for abnormal spinal curvature. Training is conducted 3 times per week (every other day) for 12 weeks.

Behavioral: Combined Exercise Therapy

Interventions

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.

Also known as: Spiral Stabilization Training
Spiral Muscle Chain (SPS) Training

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.

Combined Exercise 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.

Data Sharing

IPD Sharing
Will not share

Individual participant data (IPD) will not be shared because the study involves minors, and the data include sensitive health information related to spinal posture and neuromuscular function. According to the approved ethics protocol, strict measures are required to protect participants' privacy and confidentiality. Although all data are de-identified, sharing IPD may still pose a potential risk of re-identification. Therefore, IPD will not be made publicly available in order to ensure compliance with ethical requirements and data protection regulations.
