In young adults, the incidence of neck and shoulder pain is high, and the associated factors of neck and shoulder pain are already multifactorial in a young population.

IntroductionNeck and shoulder pain is a commonly encountered complaint in medical practice. In population studies, 20-65% of women and 15-40% of men have reported having experienced neck and shoulder symptoms during their lives [1,29]. The symptoms are also fairly common in adolescents, and may predict morbidity in adulthood [8]. It has been demonstrated that 15% of adolescents suffer from weekly neck and shoulder symptoms [19,28], the prevalence increases with age [28] and the symptoms among adolescents have increased during the last decade [21]. Neck and shoulder pain is thought to be multietiological. There is evidence to show that various work-related factors, such as repetitive tasks and working with the arms raised or the neck bent forward, are related to neck and shoulder pain [5,7]. Several psychosocial and individual factors, such as high requirements [26] or low personal control of work [2], work-related psychosocial stress [30], Abstract Several work-related, psychosocial and individual factors have been verified as being related to neck and shoulder pain, but the role of pathology visualized by magnetic resonance imaging (MRI) remains unclear. In this study, the relationship between neck and shoulder pain and cervical high-field MRI findings was investigated in a sample of persons in a longitudinal survey. The study aimed to determine whether subjects with persistent or recurrent neck and shoulder pain were more likely to have abnormal MRI findings of cervical spine than those without neck and shoulder pain. A random sample of 826 high-school students was investigated initially when the students were 17-19 years, and again when they had reached 24-26 years of age. Eighty-seven percent participated in the first survey in 1989, of whom 76% took part in the second survey, in 1996. The validated Nordic Musculoskeletal Questionnaire was used to collect data about neck and shoulder symptoms. Two groups were chosen for the MRI study: the first group (n=15) consisted of the participants who had reported no neck and shoulder symptoms in either of the inquiries, while the second group (n=16) comprised those who were suffering from neck and shoulder symptoms once a week or more often at the time of both surveys. The degrees of disc degeneration, anular tear, disc herniation and protrusion were assessed by two radiologists. The differences between the two study groups were evaluated. The study found that abnormal MRI findings were common in both study groups. Disc herniation was the only MRI finding that was significantly associated with neck pain. These findings indicate that pathophysiological changes of cervical spine verified on MRI seem to explain only part of the occurrence of neck and shoulder pain in young adults.

N eck and shoulder pain is common in the adult population in western industrialized countries. In population studies, 20-65% of women and 15-40% of men have experienced neck and shoulder symptoms during their lives (5.19). However, there are only a few report.. published on the occurrence of neck and shoulder pain in adolescents (6,17).There is a lot of evidence in the medical literature to show that neck and shoulder pain is related to static and faulty working postures (4,9,11, l5,16,18). Some evidence also exists to show that neck and shoulder symptoms are associated with emotional stress (5,13,14). Therefore, neck and shoulder pain seems to be multietiological. Unfortunately, almost nothing has been documented concerning the etiological factors of neck and shoulder pain in adolescents.Hertzberg (6) found that neck and shoulder pain in Norwegian high school student.. predicted symptoms in adult age as well. Thus, to decrease the occurrence of harmful neck and shoulder pain in adults, it is important to learn more about the etiological factors of neck and shoulder pain and the ways of preventing it in adolescence. Little is known about the methods of preventing neck and shoulder pain, but there is
