CROM - Cervical Range-of-Motion Instrument

CROM - Cervical Range-of-Motion Instrument

CROM - Cervical Range-of-Motion Instrument combines AMA-required inclinometers and magnets in an easy-to-use instrument. It eliminates positioning, zeroing and tracking errors common with stand-alone inclinometers. Standardized protocol minimizes chance for examiner error.

Features

  • CROM - Cervical Range-of-Motion Instrument takes only minutes to make objective, repeatable measurements
  • Magnetic reference eliminates shoulder and torso movements during rotation
  • Positions easily and securely like a pair of sunglasses
  • Secured to the head by hook and loop straps, eliminates tracking errors since it will not slip during movement
  • Examiner's hands remain free to guide patient's movements
  • CROM Deluxe has the benefit of some additional measurements such as protrusion, retraction, dorsal glide and rounded shoulders
  • CROM Basic includes:
    - CROM mainframe, straps and nosepiece
    - Rotation arm
    - Magnetic reference
    - Standardized written protocol
    - Instructional DVD (VHS format upon request)

More Information

  • Use the CROM to measure:
    - Sub-occipital flexion and extension
    - Cervical flexion and extension
    - Lateral flexion
    - Cervical rotation
  • How the Forward Head Unit works:
    - The CROM Deluxe includes a head forward unit for postural measurements
    - As with all CROM measurements the patient is in the preferred upright position
    - The head forward arm attaches to the CROM mainframe and the vertebra locator is held on C7
    - When the vial on the vertebra locator is level, the reading on the head forward arm is the number of centimeters between the bridge of the patient''s nose and C7
    - When the patient glides their head forward, the difference between the head forward measurement and resting measurement is protrusion
    - The patient slides their head back to get the retraction measurement
    - The difference between the two measurements is dorsal glide (or head translation in the horizontal plane)
    - By using the nose bridge and the seventh cervical vertebra as landmarks, forward head measurements are repeatable
