Introduction/Aim: Chronic lower back pain is often accompanied by changes in sleep duration and quality. On the other hand, disturbed sleep structure has a negative impact on the quality of life of patients. The aim of this study was to investigate whether there is relationship between the presence of sleep disorders and the degree of functional disability in patients with chronic low back pain.
Methods: A cross-sectional study included 150 people with chronic lower back pain who were admitted at the Krupa Health Center at Uni in the period 01 10.2016. to 01.10 2018. In addition to general questionnaire, the survey used Roland Morris Disability Questionnaire and the Pittsburgh Sleep Quality Index. The chi-square test was used in the statistical analysis of the dana.
Results: Of the 150 people with chronic low back pain, 88 (58.7%) were women and 62 (41.3%) were men. The average age of the subjects was 54.0 ± 5.7 years. Women were statistically significantly older than men. Men and women, as well as people aged 40-59 and 60-79 years, with impaired quality of sleep were significantly more likely to have a higher degree of functional disability than persons with undermined quality of sleep. In the youngest group (20-39 years),of persons with low functional disability 5.3% of them had poor sleep quality, 4.3% in group aged 40-59 years and 4.0% aged 60-79 years. Among persons with higher levels of functional disability, none had impaired sleep quality at the age of 20-39 years, and all persons aged 40-59 years and 60-79 years had impaired sleep quality.
Conclusion: Further research is needed on the relationship between the degree of functional disability of people with chronic low back pain and sleep quality. Sleep hygiene education, routine assessment of sleep quality, and early therapeutic intervention for disorders present in people with chronic low back pain can contribute to reducing functional disability as well as the cost of health care and occupational absenteeism.
