Soft collars are foam neck braces that are used to provide support and limit motion to the upper spine. Soft collars also maintain the normal alignment of the spine.
A cervical collar is often used to provide support and limit motion while an injured neck is healing. It also helps keep the normal alignment. Cervical collars can be soft (made of foam) or hard (made of metal or plastic). Because these collars can restrict the movement of your head, you may need help with eating and other activities. The skin under the collar needs to be checked every day to prevent blisters or sores.
