About this study
Official title: Validity and Reliability of the DeepClinic Mobile Application for Postural Assessment Compared With the APECS Posture Analysis System in Physically Active Adults
Posture assessment is widely used in sports medicine, physiotherapy, and rehabilitation to identify body alignment problems and support clinical decision-making. Mobile applications have become increasingly popular because they are fast, inexpensive, and easy to use. However, these applications must be shown to provide accurate and reliable measurements before they can be recommended for clinical or sports use.
The purpose of this observational study is to evaluate the validity and reliability of the DeepClinic mobile application for posture assessment in physically active adults. Approximately 50 participants will undergo standardized posture photography from the front, back, and side views. The images will be analyzed using both the DeepClinic application and the validated APECS posture analysis system. The agreement between the two systems will be examined to determine validity. To evaluate test-retest reliability, posture assessments will be repeated after one week under the same standardized conditions.
No treatment or intervention will be provided as part of this study. The findings are expected to provide scientific evidence regarding the accuracy and reliability of the DeepClinic application and its potential use as a practical posture assessment tool in clinical practice, sports science, and rehabilitation.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
DeepClinic Posture AssessmentDiagnostic test
Participants underwent standardized posture photography in anterior, posterior, and lateral views. Images were analyzed using the DeepClinic mobile application and compared with the validated APECS posture analysis system to evaluate validity. The same assessment protocol was repeated one week later to determine test-retest reliability.
APECS Posture Analysis SystemDiagnostic test
The APECS posture analysis system served as the reference method for comparison with the DeepClinic application in assessing postural alignment.

| Physically Active Adults | Approximately 50 physically active adults aged 18-45 years who regularly participated in sports were enrolled. Participants underwent standardized posture assessment using the DeepClinic mobile application and the APECS posture analysis system. The posture assessment was repeated one week later to evaluate test-retest reliability Receives: Diagnostic Test: DeepClinic Posture Assessment; Diagnostic Test: APECS Posture Analysis System |
What is being measured
The primary outcome is the main question the study is designed to answer.
Validity of the DeepClinic Mobile Application for Postural Assessment
Agreement between postural measurements obtained using the DeepClinic mobile application and the validated APECS posture analysis system. Validity will be evaluated using correlation and agreement analyses for postural alignment parameters.
Measured: Baseline (Day 1)
Secondary outcomes (2)
Test-Retest Reliability of the DeepClinic Mobile Application
Reliability of postural measurements obtained with the DeepClinic mobile application by repeating standardized posture assessments after one week. Test-retest reliability will be evaluated using intraclass correlation coefficients (ICC) and measurement error statistics.
Measured: Baseline and 1 Week
Agreement Between DeepClinic and APECS Postural Measurements
Comparison of individual postural alignment variables measured by the DeepClinic application and the APECS posture analysis system to determine measurement agreement.
Measured: Baseline (Day 1)
