CROM DELUXE CERVICAL RANGE
OF MOTION MEASUREMENT DEVICE

Price:$358.00

The cervical range of motion (CROM) device is an instrument that was designed to aid in the evaluation of the range of motion of the cervical spine and has been shown to have a high degree of interrater reliability and reproducibility in that regard.7,8 The instrument consists of a spectacle frame that is worn by the subject. There are 3 dial angle meters attached to the instrument. A sagittal plane meter and lateral flexion meter serve as gravity meters that can assess a chin elevation or depression and head tilt, respectively. A third meter is a magnetic compass that responds to a shoulder-mounted magnetic yoke and can measure a face turn (Figure 1). Each of the 3 meters can be read to an accuracy of approximately 1°. Theoretically, the CROM device might be ideal for use in the ocular motility examination for assessing abnormal head positions, limitations of ductions, and the range of single binocular vision at distance viewing. The purpose of this study is to assess that possibility. Use the CROM (Cervical Range-Of-Motion) device to easily and quickly obtain accurate, objective, repeatable measurements of cervical movement.

The CROM is the only instrument for which normal values have been established for medical professionals assessing patient cervical range of motion.

The CROM combines magnets with inclinometers. It eliminates slippage, positioning, zeroing and tracking errors common with stand-alone inclinometers, plus it allows measurement of rotation movements in the upright position.
