Summary

This study aims to investigate the clinimetric properties of the iPhone Level application as a suitable alternative to the Back Range of Motion device in assessing lumbar range of motion, including flexion, extension, and lateral flexion.

Conditions

  • Lumbar Pain Syndrome

Interventions

DEVICE

easement tool 1 - BROM device

The BROM device consists of an inclinometer for measuring sagittal plane motions (flexion/extension) and a gravity goniometer/compass for lateral flexion. Participants stood upright with feet apart. Measurements were taken for flexion, extension, and bilateral lateral flexion. Three trials per movement were recorded and averaged.

DEVICE

Measurement tool 2 - iPhone level application

The iPhone Level app was placed at T12-L1 and S1-S2 spinal levels. Lumbar flexion and extension ROM was calculated by subtracting S1-S2 angle from T12-L1 angle. For lateral flexion, the app was placed at T12 and S2 and the same subtraction method applied. Three trials per movement were recorded and averaged.
