Smartphone "Selfies"-A reliable and accurate tool for measuring elbow range of motion.

ABSTRACT:

Background

To determine if self-taken photographs ("selfies"), performed independently after instruction by video or illustrated handout, would be an accurate and reliable tool for capturing elbow range of motion in patients with elbow contractures.

Methods

Fifty patients presenting with elbow contractures participated in the study. After completion of the selfie, the senior author clinically measured flexion and extension with a goniometer. The angles from the photographs were measured and analyzed.

Results

The agreement between goniometer and "selfie" measurements correlated closely (R² = 0.98) and agreement was excellent in both extension and in flexion with intra-class correlation coefficients of 0.95 (95% CI 0.92 to 0.97) in extension with a mean diffe
