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.
Being over 18 years of age,
being able to stand and walk without an assistive device,
not having experienced back pain or lower extremity pain in the last 6 months,
and being willing to participate in the study.
Lack of consent,
lower extremity injuries (dislocation, sprain) within one month prior to measurement,
lower extremity fractures within the last 6 months,
tactile sensitivity that prevents the adoption of a free and habitual posture.
healthy older individuals

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).
