The OTC 2394 soft cervical collar is often used in cases of muscle tension or minor cervical injuries. It provides limited cervical motion control, and is recommended wherever a reminder against making quick and painful neck movements is required. Use the OTC Cervical Collar to support the head, limit motion of painful vertebrae and provide the most comfortable position, which is usually when the neck is in a neutral position. This tends to open the nerve pathway and unweight the vertebrae.
