Abstract

The purpose of this study was to assess the reliability of a markerless motion capture system, the VALD HumanTrak, for estimating shoulder range of motion. Intra- and interday and fixed- and free-range reliability was assessed for shoulder sagittal and frontal plane movements. Results were calculated for three sessions, with 16 general population participants completing the protocol. ICC ranged from good to excellent for abduction (0.753 - 0.959) and flexion (0.868 - 0.975) and poor to good for adduction (0.417 - 0.893) and extension (0.443 - 0.757). The HumanTrak can be a reliable tool to estimate shoulder range of motion within or across days and is a novel measurement tool that has potential use in clinical settings.
