What Muscles Are Affected by Whiplash?


Whiplash is a common injury resulting from car accidents, especially in rear-end collisions. It occurs when the head is suddenly jerked forward and then backward, causing the neck to move beyond its normal range of motion. This abrupt movement can strain the neck muscles and ligaments, leading to pain, stiffness, and a range of other symptoms. Understanding which muscles are affected by whiplash can help individuals recognize the severity of their injuries and seek appropriate legal and medical assistance.

The Impact on Neck Muscles

The primary muscles impacted by whiplash are those in the neck and upper back. These include:

  • Sternocleidomastoid (SCM): This muscle runs from the back of the ear down to the collarbone and is crucial for head rotation and flexion. Whiplash can cause this muscle to stretch or tear, leading to neck pain and restricted movement.
  • Trapezius: This large muscle extends from the neck to the mid-back and shoulders. It supports the arms and shoulders and helps with head movement. Trauma from whiplash can lead to trapezius muscle strain, resulting in shoulder and upper back pain.
  • Cervical Paraspinal Muscles: These muscles run along either side of the spine in the neck. They are responsible for neck stability and movement. Whiplash can cause inflammation and spasms in these muscles, contributing to stiffness and discomfort.
  • Scalene Muscles: Located on each side of the neck, these muscles help with breathing and assist in neck rotation. Whiplash can lead to scalene muscle strain, causing pain in the neck and numbness or tingling in the arms.

Secondary Muscles Affected

In addition to the primary neck muscles, whiplash can also affect secondary muscle groups, including:

  • Levator Scapulae: This muscle connects the cervical spine to the shoulder blade and is often affected by whiplash, leading to pain and difficulty in moving the neck and shoulders.
  • Suboccipital Muscles: These small muscles at the base of the skull are responsible for head movement and posture. Whiplash can cause tension and spasms in these muscles, resulting in headaches and neck pain.
