BackBone: Journal of the American College of Spine Surgery

The purpose of this study was to assess the benefits, if any, of having dual adjustment on the cervical neck collar -- which allows for height adjustment and allows tilting of the neck slightly to the right or to the left. The collars are used for treatment of acute neck injury, painful cervical degenerative changes as well as post-surgical neck cases. Results indicate that dual adjustable collars provide more comfort and pain relief and allow for more air circulation and less skin irritation for patients as opposed to the single adjustment control collars.
