Abstract
Neck pain and headaches related to neck pain will affect an estimated two thirds of the population at some time during their life. The pain may be caused by high-intensity exertion, such as whiplash, or from prolonged low-intensity exertion. An accepted explanation for neck pain is fatigue of the neck muscles caused by the sustained contraction which is required to hold the head in position. Studies suggest that a significant reduction of muscle function is a result of long term neck fatigue. Thus, an individual suffering from neck pain may have reduced muscle function, limiting activity and requiring changes in daily activity. Further, neck pain or fatigue may affect other areas of the body. One study found that leg muscle activation significantly decreased as the back muscles fatigued. Similarly, neck fatigue may limit upper extremity function, specifically hand dexterity and grip strength.
