Sometimes I see people wearing soft neck collars after car accidents. When should these be used?

Many studies show that these collars are not effective and should not be used. Early movement, exercise, and advice on posture have proven useful in treating whiplash injury. Returning to usual activities is preferable to rest and wearing a collar.

Occasionally, a doctor or physical therapist may advise a patient to use a soft collar for 24 to 48 hours. This is an individual decision based on the particulars of the case.
