Since the 1990s, the deep neck flexors have been getting most of the attention as being the “missing link” in rehab of the neck after whiplash. As important as the deep neck flexors are, the deep neck extensors cannot be ignored. In fact, BOTH the deep neck flexors and extensors have to work in concert to control segmental movement! A 2013 study reported the deep neck extensors can become quite de-conditioned and weak in patients with neck pain. Recent studies confirm that neck pain patients typically display reduced activation AND a less defined activation pattern in the deep neck extensors, and the amount of weakness and poor activation is proportional to the amount of pain present (i.e., the higher the pain level, the worse the activity response).
