Validation of the Spin-T Goniometer, a Cervical Range of Motion Device

This study quantifies the difference between the MotionStar and the Spin-T goniometer and documents the systematic error between the measures. Where the error reached statistical significance, the magnitude of the error was very small (<1.5°). The results of this study suggest that the Spin-T goniometer may be used as a valid measuring instrument for cervical range of movement.
