stimulation on the skin, is of unclear benefit in chronic neck pain. Epidemiology Neck pain affects about 330 million people globally as of 2010 (4.9% of the population). It is more common in women (5.7%) than men (3.9%). It is less common than low back pain. Prognosis About one-half of episodes resolve within one year and around 10% become chronic. Prevention Prevalence of neck pain in the population suggests it is a common condition. For cervicalgia associated with bad posture the treatment is usually corrective in nature (i.e. ensure shoulders are in one line above the hips) and relating to interventions that provide ergonomic improvement. There is also growing research in how neck pain caused by mobile devices (see iHunch) can be prevented using embedded warning systems.
