The BROM II (Back Range of Motion Instrument) includes the same inclinometer based instrument as the BROM Basic for measuring rotation and lateral range of motion of the lumbar and thoracic spine. The BROM is the only instrument that can measure lumbar rotation accurately. The BROM II features a unique, inclinometer based flexion/extension unit that allows multiple examiners to obtain accurate and repeatable measurements. The BROM uses a standardized written protocol.
