Abstract
Introduction. Dentists, due to the specificity of their professional work, consisting in prolonged stay in a static sitting position, frequent tilting and rotation of the torso, repeated sequences of movements, are at risk of diseases of the musculoskeletal system, which can lead to disability. The aim of this study was to evaluate an impact of chosen factors on the degree of disability resulting from pain in the cervical and lumbar spine among dentists.
Material and methods. The results of a diagnostic survey performed among 97 professional active dentists aged 30-40 years, who during 2 years preceding the study experienced back pain, were analysed. The research tool was the author’s questionnaire, Neck Disability Index (NDI) and Oswestry Distability Index (ODI). The collected research results were analysed with the use of Mann-Whitney U test and Spearman rank correlation.
Results. Only 4% of dentists declared reliable compliance with the principles of ergonomics at work, and 72% of respondents undertook physical activity in their free time. No statistically significant relationships were found between age, body composition, seniority in the profession of a dentist, the number of working hours per day, and the level of disability determined on the basis of the NDI and ODI. Working from lateral or posterior access, taking up physical activity, and using physiotherapeutic procedures were not factors differentiating the level of disability of the respondents.
Conclusions. There is a need to create programs popularizing the need for reliable compliance with the principles of ergonomics in the profession of a dentist, and the implementation of new concepts of work organisation with reference to researched professional group.

Streszczenie

Purpose. The aim of the study was to compare the frequency and location of musculoskeletal disorders occurring among office and production workers, and to analyze the relationship between the occurrence of pain and the type of workload, age, gender and Body Mass Index.
Material and methods. The study consisted of 63 randomly chosen office and production workers aged 23-65.
The research was based on the analysis of pain occurrence and characteristics of professional activities.
Results.
There were statistically significant correlations found between: cervical spine pain among women and work in the forced body position and long-term inability to change position, thoracic spine pain and work for over 12 hours a day, repetitive movements, work in a forced position of the body and lifting / carrying heavy loads, lumbar spine and work in a forced body position and lifting/carrying of heavy loads.
Correlation between BMI and age and pain occurrence was not significant.
Conclusions
1. Characteristics of work-related activities determine the location of pain.
2. The most common work-related musculoskeletal pain syndromes concerns lumbar and cervical spine as well as hand’s and wrist’s joints.
3. Occurrence of pain related to the work performed is dependent on gender, but not on the age or BMI of the respondents.
4. Regular physical activity reduces the risk of work-related musculoskeletal pain syndromes.

M. Zygmańska, A. Błaszczyk, K. Wegner, W. Samborski, M. Ogurkowska – Assessment of overload changes in the lumbar spine of employees with sedentary nature of work; Fizjoterapia Polska 2018; 18(1); 62-73

Abstract

Objective. The objective of the study was to specify the lumbar spine overload changes in women and men working in a sitting position and to establish when the feeling of discomfort intensifies.
Static position for a long periods of time leads to lumbar spine overload changes. Apart from professional risk factors, sedentary lifestyle also has a tremendous impact on degenerative changes in intervertebral discs.
Material and Methodology. A survey was conducted among 62 office employees, 29 women and 33 men aged 23-61, from a selected corporation, who experienced lumbar pain episodes. The survey was based on the subjective part of the McKenzie method test supplemented with an anthropometric part.
Results. Lumbar pain was reported by 84% percent of the subjects, with the somatic symptoms gender-differentiated and co-occurrence of neck and lumbar pain/discomfort. The pain intensified proportionately to the subjects’ age and when performing professional duties.
Conclusion. Although there are reports on the development of overload changes, sedentary work continues to cause back pain. Cervical and lumbar discomfort is indicative of compensation. An inappropriate sitting position is the reason for accelerated development of overload changes and the related pain.
