BROM II
Like the CROM, the BROM II (Back Range-Of-Motion instrument) combines inclinometers and magnets for accurate, objective ROM measurement that is standardized and consistently repeatable. The BROM II is superior to "stand alone" inclinometers because it measures flexion and extension, rotation, lateral flexion and pelvic tilt without the positioning, zeroing and tracking errors common to these instruments. The BROM II comes with an instructional video.
