First seen Jul 02, 2026 · Last updated Jul 02, 2026
Summary
This study compares a smartphone app (iPhone Level) to a specialized device (BROM) for measuring how much the lower back can bend forward, backward, and sideways. Researchers will enroll 120 healthy male university students aged 18–25 with normal body weight. If the app works well, it might become a simple, inexpensive way to assess back motion.

Active substance
iPhone Level application
What this could lead to
If the app proves accurate, it could offer a low-cost, accessible way to measure back motion in clinics or at home.
What could go wrong
This is a small, early-stage study in healthy young men only, so results may not apply to people with back pain or other ages. The app may not match the precision of the dedicated device.
