Whiplash is a common injury to occur after a MVA. It typically involves a quick uncontrolled or "whip" like motion to the neck in the event of a sudden stop. This action may cause ligament damage around the spinal vertebrae, muscle strains, joint misalignment and in some severe cases fracture. Symptoms commonly include decreased range of motion, minimal to severe muscle guarding, trigger point tenderness and headaches. Treatment includes modalities to decrease pain and inflammation, along with a large component of hands-on manual techniques that are effective in regaining range of motion, decreasing muscle guarding and promoting optimal movement.
