NCT07510503

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Assessment of Spinal Curvature

    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).

    Two measurements taken 10 minutes apart.
