Artificial Intelligence-Based Postural Feedback for Scoliosis
A study testing Postural feedback and Physical therapy for scoliosis in people with Postural Alignment and Idiopathic Adolescent Scoliosis, run by Mahidol University at 1 site in Thailand.
Trial summary
Due to advancements in technology, Posture-Analyzing and Virtual Reconstructing (PAViR) systems were developed. They used Red-Green-Blue-Depth camera sensors and artificial intelligence to evaluate human posture alignment, muscle balance, and movement without the use of radiation or physical markers.

About this study
Official title: The Effect of Artificial Intelligence-Based Postural Feedback on Posture Correction in Idiopathic Scoliosis Patients
Due to advancements in technology, Posture-Analyzing and Virtual Reconstructing (PAViR) systems were developed. They used Red-Green-Blue-Depth camera sensors and artificial intelligence to evaluate human posture alignment, muscle balance, and movement without the use of radiation or physical markers. This technology served as a portable, X-ray-like device that was safe and user-friendly, providing detailed views of bone and muscle models alongside easy-to-understand 3D visualizations. However, how to utilize the data obtained from PAViR to support traditional treatment remained unclear. To fill this gap, this study aimed to investigate the effects of AI-based postural feedback on posture correction in patients with idiopathic scoliosis.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Postural feedbackOther
The physical therapist reported the findings from the PAViR system to the participants during a 10-minute session. Data regarding skeletal alignment and muscle imbalances were provided to enhance participants' self-awareness of their specific postural issues. Furthermore, these insights were integrated into the subsequent training sessions for the experimental group.
Physical therapy for scoliosisOther
The physical therapist conducted 60-minute sessions. These sessions were grounded in the principles of the Schroth Method and Physiotherapeutic Scoliosis-Specific Exercises (PSSE).
| Study group | Role | What they receive |
|---|---|---|
| AI-Based Postural Feedback Group | Experimental | Participants in the experimental group received postural feedback via the PAViR system, integrated with posture correction exercises and physical therapy for scoliosis. Receives: Other: Postural feedback; Other: Physical therapy for scoliosis |
| Conventional Postural Feedback Group | Active comparator | Participants in the control group received the same exercise and therapy sessions, but without the postural feedback provided by the PAViR system. Receives: Other: Physical therapy for scoliosis |
What is being measured
The primary outcome is the main question the study is designed to answer.
REEDCO postural score
The REEDCO Posture Assessment was used to evaluate postural scores during comfortable standing and postural self-correction.
Measured: before and immediately after intervention
Angle of trunk rotation
A scoliometer was used to evaluate the angle of trunk rotation during Adam's Forward Bend Test.
Measured: before and immediately after intervention
Postural Variables Derived from a 3D Motion Analysis System
A 3D motion analysis system (VICON Motion Systems Ltd., Oxford, UK) was used to evaluate postural variables during comfortable standing, postural self-correction, and the Adam's Forward Bend Test.
Measured: before and immediately after intervention
Postural Variables Derived from a PAViR System
A PAViR system (MGsolutions Inc., Seoul, South Korea) was used to evaluate postural variables during comfortable standing, postural self-correction, and the Adam's Forward Bend Test.
Measured: before and immediately after intervention
Secondary outcomes (2)
Illness Perception
The Brief Illness Perception Questionnaire (IPQ-B) was an accurate and valid assessment tool to measure and monitor illness perceptions. It consisted of nine items rated on a scale from 0 (minimum) to 10 (maximum). The first five assessed cognitive perceptions such as the effect on life (item 1); duration of illness (item 2); control over illness (item 3); beliefs about the effectiveness of treatment (item 4); and experience of symptoms (item 5). Items 6 and 8 assessed emotional aspects, which included concern about the illness and a multifaceted question about mood. Item 7 assessed the degree of understanding of the illness. The final item was open-ended, asking respondents to rank the three most important factors causing their illness.
Measured: before and immediately after intervention
Exercise Motivation
The Behavioral Regulation in Exercise Questionnaire-2 (BREQ-2) was a 19-item questionnaire that measured the stages of the self-determination continuum with respect to motivation to exercise using a 5-point Likert scale (0 = not true for me, 4 = very true for me) and was modified by Markland and Tobin. The version by Markland and Tobin added an amotivation factor to the original external, introjected, identified, and intrinsic regulation factors.
Measured: before and immediately after intervention
