NCT07341633

Brief Summary

This randomized controlled trial (RCT) evaluates the efficacy of a novel Artificial Intelligence (AI)-based digital therapeutic system compared to traditional outpatient Schroth exercises for the treatment of Adolescent Idiopathic Scoliosis (AIS). The intervention utilizes a smartphone application with computer vision technology to perform remote, personalized posture analysis and generate adaptive exercise prescriptions. The study aims to determine if this "Human-in-the-Loop" AI model demonstrates superior clinical outcomes in controlling spinal curve progression and improving treatment adherence compared to standard conservative care over a 6-month period.

Outcome Measures

Primary Outcomes (1)

  • Absolute Change in Major Curve Cobb Angle

    Measured on standardized standing posteroanterior full-spine radiographs. The Cobb angle is the angle formed between the upper endplate of the most tilted upper vertebra and the lower endplate of the most tilted lower vertebra. Measurements are performed in degrees by independent radiologists who are blinded to group allocation. A negative value indicates a reduction (improvement) in the spinal curve.

    Baseline, 3 months, and 6 months

Secondary Outcomes (4)

  • Treatment Adherence Rate

    Baseline, 3 months, and 6 months

  • Change in Angle of Trunk Rotation (ATR)

    Baseline, 3 months, and 6 months

  • Change in Quality of Life (SRS-22r Score)

    Baseline, 3 months, and 6 months

  • Change in Trunk Appearance Perception (TAPS)

    Baseline, 3 months, and 6 months

Study Arms (2)

Standard Outpatient Schroth Therapy

ACTIVE COMPARATOR

Participants receive standard conservative care based on Schroth Best Practice guidelines. This involves an initial 60-minute comprehensive evaluation, followed by a personalized home exercise program (30 minutes daily). Participants attend monthly supervised sessions at the outpatient clinic for manual prescription adjustments by a certified therapist .

Behavioral: Standard Outpatient Schroth Therapy

AI-Based Digital Therapeutics (AI-DTx)

EXPERIMENTAL

Participants utilize a smartphone application to capture standardized photos every two weeks. An AI algorithm (MediaPipe-based) processes these images to classify curve patterns and assign personalized exercise modules. The system uses a "Human-in-the-Loop" workflow where a Clinical Research Assistant verifies the AI-generated prescription before release. Dosing intensity is adaptively adjusted based on metric changes.

Device: AI-Based Digital Therapeutic System

Interventions

Standard conservative management based on the SOSORT and Schroth Best Practice guidelines. Participants undergo an initial 60-minute comprehensive evaluation and education session. The intervention consists of a daily home exercise program (30 minutes/day) and mandatory monthly face-to-face supervised sessions at the outpatient clinic, where a certified therapist manually adjusts the exercise prescription based on clinical progression .

Standard Outpatient Schroth Therapy

A smartphone-based digital therapeutic application that utilizes computer vision (MediaPipe Framework) to capture and analyze patient posture bi-weekly. The system employs a hierarchical triage logic to classify curve patterns and assign personalized Schroth-based exercise modules. It features a "Human-in-the-Loop" safety protocol where a Clinical Research Assistant validates the AI-generated prescription before release. The exercise dosing (intensity and props) is adaptively adjusted based on the calculated metric changes (NSI) every two weeks .

Eligibility Criteria

Age10 Years - 18 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Diagnosis of Adolescent Idiopathic Scoliosis (AIS).
  • Age between 10 and 18 years (inclusive).
  • Cobb angle of the major curve between 10° and 30°.
  • Risser sign 0-2 (indicating skeletal immaturity).

Masking Details
Due to the visible nature of the exercise intervention, it is not possible to blind participants or care providers. To minimize detection bias, the primary outcome (Cobb angle) will be assessed by independent radiologists who are strictly blinded to group allocation and the timing of the radiographs.
