Neck and shoulder pain in a young population: prevalence and etiological factorsSiivola, S. (Sari) 30 August 2003 (has links)
Abstract
This study comprised three parts: a cross-sectional survey of 826 high school students, a 7-year follow-up survey of the same sample, and a MRI study of a subgroup (n=31) of the follow-up study population. Firstly, the aims of the study were to determine the prevalence and incidence of neck and shoulder pain (NSP) in populations 15-18 and 22-25 years old, and to evaluate sociodemographic factors, body size measurements, psychological factors and leisure time activities as possible associated and predictive factors of NSP. Secondly, the aim was to find out whether structural changes of the cervical spine detected by magnetic resonance imaging (MRI) were associated with NSP in young adults.
The results showed the prevalence of self-reported weekly NSP in 15- to 18-year-old adolescents to be 17%, and in seven years, the prevalence of weekly NSP had increased to 28%. After seven years, the six-month incidence of occasional or weekly NSP was 59% among those asymptomatic at baseline. In the cross-sectional study, female gender, low physical activity, hobbies which statically load the upper extremities, low intensity of physical exercise, self-assessed moderate physical condition and psychosomatic symptoms and depressive mood were associated with a high prevalence of NSP, and sports which dynamically load the upper extremities were associated to a low prevalence of NSP.
Symptoms in adolescence were associated with a high prevalence of NSP seven years later. Activity in sports, which dynamically load the upper extremities in adolescence, was associated with a low prevalence of NSP in adulthood. Of all variables in the study, psychosomatic symptoms were most congruently associated with a high prevalence of NSP, and psychosomatic symptoms in adolescence also predicted NSP in adulthood. In the MRI study, disc degeneration and anular tears of the cervical spine were common in asymptomatic and symptomatic subjects. Disc herniations were the only abnormal finding that was significantly more common in symptomatic subjects.

Repetitive and monotonous work among women : Psychophysiological and subjective stress reactions, muscle activity and neck and shoulder painRissén, Dag January 2006 (has links)
<p>Repetitive and monotonous work is frequently associated with neck and shoulder pain and negative psychosocial factors inducing stress reactions. The present thesis concerns the relations between psychophysiological and subjective stress reactions, muscle activity measured by surface electromyography (SEMG) in the trapezius muscle, and neck and shoulder pain in women performing repetitive and monotonous work. In Study I cardiovascular and subjective stress reactions were investigated during computer work in a laboratory setting. The findings indicated that heart rate variability is a more sensitive and selective measure of mental stress compared with blood pressure recordings. Study II explored the relations between stress reactions and muscle activity during supermarket work. The results showed that perceived negative stress reactions may have a specific influence on muscle activity in the neck and shoulder region, which can be of importance for work-related musculoskeletal disorders in repetitive and monotonous work. In Study III the association between SEMG activity patterns and neck and shoulder pain was investigated during cash register work. It was found that pain-afflicted women had a different muscle activation pattern (more static, more co-contraction, less muscle rest) compared with pain-free women. Study IV was a follow-up study evaluating the introduction of job rotation among female cashiers. The results indicated positive effects on diastolic blood pressure, muscle activity, and partly on neck and shoulder pain, although perceived stress was unchanged. It was concluded that job rotation seems to have a limited effect on chronic neck and shoulder pain, but may be an effective preventive measure. The empirical findings are particularly relevant for women who, compared with men, more often perform repetitive and monotonous work and are also more often affected by neck and shoulder pain.</p>

Promoting return to work : lay experiences after sickness absence with musculoskeletal diagnosesÖstlund, Gunnel January 2002 (has links)
Introduction: Musculoskeletal disorders constitute the greatest cause of sickness absence from work. Despite research and efforts at rehabilitation, sickness absence due to these disorders has not decreased, but has instead increased, particularly in women. Clients’ perceptions of care and rehabilitation, i.e. knowledge generated from a lay perspective, is a neglected area of research. This thesis deals with lay experiences of rehabilitation following sickness absence due to back, neck or shoulder problems, termed musculoskeletal disorders (MSD). Aim: The overall aim was to examine hindering and promoting processes in rehabilitation after sickness absence due to MSD from a lay perspective. Specific aims were to study how lay persons experience rehabilitation agents and rehabilitation activities (paper I), how they describe themselves and their experience in relation to work (paper II), the significance of the private arena regarding return to work (paper III), and how clients who have experienced sickness absence due to MSD perceive contact with rehabilitation agents (paper IV). Method: The study population in the four papers is part of a cohort of persons living in the same municipality and who in 1985 were aged 25-34 years and were sick-listed due to back, neck or shoulder diagnoses for 28 days or more, n=213. During 1995, 148 persons in the cohort responded to a questionnaire, and in 1997-1998, 20 of these persons were interviewed concerning their experiences with rehabilitation. In papers I, II and III the qualitative method of Grounded Theory was used with a focus on creating an empirically-based theory concerning the area under study. Data collection was strategic and analysis of the tape-recorded interviews was done on a continual basis. How previously sick-listed persons experienced contact with professional rehabilitation agents in t he health care sector and social insurance office was investigated in paper IV. Factor analysis and multiple regression analysis were used to analyse the data in this study. Results: The interview study shed light on lay persons’ experiences with medical, social and work-related measures in rehabilitation, their perceptions of rehabilitation actors and family members in relation to rehabilitation, and their self-presentations. The descriptions of lay persons concerned three arenas, the health care arena, the occupational arena, and the private arena. Dilemmas and difficulties in these arenas were described, such as handling the duty to work, experiencing domestic strain, and the experience of lacking socioemotional support from significant persons during the rehabilitation process. In paper I some ideal types of rehabilitation agents emerged from the interviewees’ descriptions concerning the health care arena, and we called these the routine bureaucrat, the empathic administrator, the distant technician, and the professional mentor. The latter agent was requested and was described as a person who could provide socioemotional support, who had professional competence, and who could function as a unifying link during the rehabilitation process. The results from paper II showed that in their self-presentations, the interviewees expressed having a duty to work and that there were differences in how they handled this sense of duty. The selfpresentations contained descriptions of work as a part of personal identity and could be summarised in the following ideal types: the work manic, the workhorse, the workaholic and the relaxed worker. The latter used a strategy that can be considered to promote rehabilitation in that the individual himself/herself had control over his/her work and worked in accordance with his/her own needs rather than those of others. Paper III focused on the private arena. Different patterns were found in the experiences of men and women. Women related that their responsibility for the home and domestic work seldom left any time for themselves, including any time for rehabilitation. Men more often reported having time for themselves that could be used for leisure activities and rehabilitation. Some of the women said that they lacked socioemotional support from their partner and that they had a great deal of responsibility for housework, which seemed to be a hindrance in returning to work after sickness absence. Furthermore, these women, like most of the men, had little education, which could make finding other work alternatives more difficult. Based on the interviews, a hypothesis was developed regarding domestic strain that is related to the distribution of domestic work, the distribution of responsibility for the home, and the quality of the marital relationship. Paper IV dealt with clients’ perceptions of contact with rehabilitation agents in health care and the social insurance office. Three latent dimensions were found in the respondents’ ratings of these contacts: supportive treatment, distant treatment, and empowering treatment. Sex, disability pension status, mental health and diagnostic group were significantly related to how these dimensionswere rated. Women perceived the treatment from both types of rehabilitation agents as more supportive than men. Contact with the social insurance offices were rated higher by persons with disability pensions than by those who had returned to work. Men rated their contact with rehabilitation agents at social insurance offices high on the dimension of distant treatment. Respondents with mental health problems rated the contact as distant for both types of rehabilitation agents, but contact with health care was also scored low on the supportive dimension. Finally, respondents with neck/shoulder diagnoses rated contact with rehabilitation agents in health care as more empowering than was done by persons with back diagnoses. Conclusions: From a lay perspective rehabilitation following sickness absence due to MSD occured in three arenas, the health care arena, the occupational arena and the private arena, where the quality of relationships both with rehabilitation agents, persons at work and in one’s private life was described as important regarding the rehabilitation process. This thesis also showed that both sex and health were important factors regarding how lay persons’ perceived contacts with rehabilitation agents during the rehabilitation process following sickness absence due to MSD.
