The Relationship between Forward Head Position and Dorsal Kyphosis with non-specific Chronic Low Back Pain in Military Mans

Background and Aim: Improper body posture and differences in spinal angles can lead to orthopedic injuries. Forward head and kyphosis are some of the complications of improper posture that can lead to back pain. The aim of the present study was to investigate the relationship between forward head position and dorsal kyphosis with non-specific chronic low back pain in military mans. Methods: In this cross-sectional study, 60 middle-aged military men aged were purposefully divided into two groups of 30 people with non-specific chronic low back pain and healthy (Age range: healthy 43.4 ± 10/10 years and low back pain 45.1 ± 6.6 years). Then, information related to dorsal kyphosis was collected with a kyphometer, range of motion of the back by goniometer, and forward head position using a body-vision device. Kolmogorov – Smirnov test was used for data normality and Independent t and chi-square tests were used for data analysis in Spss19 software with significant level (P <0.05). Results: The results showed that there was a significant difference between forward head position in patients with chronic low back pain and without low back pain (P = 0.036). While there was no significant difference between lumbar kyphosis in people with chronic low back pain and without low back pain (P = 0.73). In the correlation study, it was found that there was no significant relationship between lumbar kyphosis and forward head in people with chronic back pain (P = 0.924) and healthy people (P = 0.062). The angle of range of motion of the lumbar spine was not significantly related to the angle of the thoracic kyphosis angle in patients with chronic low back pain (P = 0.088) and healthy individuals (P = 0.544). In addition, forward head position was not significantly associated with VAS in patients with chronic low back pain (P = 0.330), but a significant association between forward head position and VAS was confirmed in healthy subjects (P = 0.006). Conclusion: By examining the spine and examining neck pain in healthy military men, it is possible to detect postural changes and prevent chronic back pain. Postural evaluation also helps to correct any pain and abnormal condition of weak muscles by prescribing corrective exercises.
