简要总结
This study will include healthy volunteers aged 18-25 years. Demographic information will be recorded, and an experienced physiotherapist will mark five reference points on the spine of the participants, starting from the cervical spine and extending to the lumbar spine. Angle measurements will then be taken from these five reference points using a gravity inclinometer, an Android smartphone, and an iOS phone. Measurements will be repeated twice on the same day and twice again 24-48 hours later using three different devices. The accuracy and similarity of the measurements taken with these three devices will then be compared.
详细描述
This study is designed as an observational, methodological study to investigate the intra-rater and inter-rater reliability and concurrent validity of two smartphone-based inclinometer applications used for sagittal spinal curvature assessment.
The study will include healthy volunteers aged 18-25 years. Participants will be informed about the study procedures, and written informed consent will be obtained before enrollment. Demographic and anthropometric characteristics, including age, sex, height, body weight, and body mass index, will be recorded.
Measurement Procedures An experienced physiotherapist will identify and mark five anatomical reference points along the spine, extending from the cervical region to the lumbosacral region. These reference points will be used to standardize the measurement locations across devices and assessment sessions.
Sagittal spinal inclination angles will be measured using three different devices:
A conventional gravity-based bubble inclinometer. An Android smartphone equipped with an inclinometer application. An iOS smartphone equipped with an inclinometer application. Measurements will be performed at the same anatomical reference points using all three devices. The conventional inclinometer will serve as a reference instrument for evaluating the concurrent validity of the smartphone applications.

结局指标
主要结局
Assessment of Spinal Curvature
时间窗: Two measurements taken 10 minutes apart.
Description: The following 5 parameters were used for the measurement: 1. ALPHA 1 angle of sacrum (upper beam of the inclinometer, in the middle of the intervertebral space, on the line connecting the posterior superior iliac crests). 2. ALPHA 2 angle - sacrolumbar junction S/L (center of the inclinometer on the line connecting the posterior superior iliac crests). 3. BETA angle - Th12-L1 thoracolumbar junction (center of the inclinometer at the thoracolumbar junction). 4. GAMMA angle - C7-Th1 (center of the inclinometer on C7). 5. DELTA angle - Th3-Th4 (upper beam of the inclinometer at the height of the upper angle of the scapula).
