Many researchers have suggested that neck pain has
a local physio-pathologic cause, and that this cause can be
identified and treated (Travell and Simons, 1983). Others
consider neck pain as a primarily nonorganic problem with
psychological and social roots (biopsychosocial model) and
that psychosocial disturbances have the major influence on
MNP (Hogg-Johnson et al., 2008). The relationship between
psychosocialepsychological variables, physical impairment,
and neck pain and disability is complex and not yet fully
understood (Linton, 2000).
