ارتباط میان دامنه حرکتی و انحنای لوردوتیک ستون فقرات در ناحیه کمری با کمردردهای غیراختصاصی

Aims and Background: Non-specific low back pain has direct impact on quality of life, active days at work and healthcare cost. The purpose of this investigation was to study the relationship between lumbar lordosis and lumbar range of motion with non-specific low back pain. Methods and Materials: 50 students of kharazmi University (mean age :24 years, mean weight: 75.72 kg, mean height :180.5 cm ,and mean BMI :22.33) took part in this study as subjects. They were divided to 3 groups according to the severity of low back pain which was measured by Oswestry questionnaire. Some of the anthropometric characteristics of subjects such as length of lower extremity and width of pelvic girdle were measured by body composition analyzer system and some other anthropometric instruments. For measuring the angle of lumbar lordosis and lumbar range of motion , we used the Spinal Mouse System. Findings: The result showed that there was not any significant relationship between anthropometric and individual characteristics and lumbar lordosis with severity of low back pain (p<0.05). According to our results, it has been revealed that there is a negative relationship between lumbar range of motion and severity of low back pain (p<0.05). Conclusion: Therefore, it is possible that decreased lumbar range of motion may increase the risk of low back pain.
