Neck pain is one of the three most frequently reported complaints of the musculoskeletal system. Twenty-six to 71% of the adult population can recall experiencing an episode of neck pain or stiffness in their lifetime. Neck pain is usually a benign and self-limited condition, but can be disabling to varying degrees. As such, it has a large impact on healthcare expenditure, due to visits to healthcare professionals, and sick leave, disability and the related loss of productivity.(Trinh 2010)
Neck pain can be associated with symptoms that radiate to the arms or head, and may involve one or several neurovascular and musculoskeletal structures such as nerves, nerve roots, intervertebral joints, discs, bones, muscle and ligaments.
Acupuncture can help relieve neck pain by:
stimulating nerves located in muscles and other tissues, which leads to release of endorphins and other neurohumoral factors, and changes the processing of pain in the brain and spinal cord (Pomeranz 1987, Zhao 2008);
reducing inflammation, by promoting release of vascular and immunomodulatory factors (Kavoussi 2007, Zijlstra 2003);
improving muscle stiffness and joint mobility by increasing local microcirculation (Komori 2009), which aids dispersal of swelling.
