Comparison of the effect of a course of posture correction and strength exercises with emphasis on head and neck position on pain, neck muscle weakness and range of motion in inactive men with chronic neck pain.

Background and Objectives: In the last two decades, the prevalence of neck pain has been increasing and now it is considered the second musculoskeletal disorder after back pain. The general purpose of this research is to compare the effect of a course of posture correction and strength exercises with emphasis on the head and neck position on Pain, weakness of neck muscles and range of motion of inactive men with chronic neck pain. Research method: The current research was a semi-experimental type with a pre-test-post-test Materials and Methods:The statistical population was composed of inactive men with chronic neck pain in Tehran, who were selected by random sampling of 30 men who do not do any sports activities during the day (inactive) and have chronic neck pain. After the pre-test, the samples were randomly divided into three groups of 10 people who were trained for 6 weeks. In order to measure the research variables, VAS pain scale, Roland Morris disability index and neck flexion and extension (lateral flexion and neck rotation) were used. Data analysis was done using SPSS24 software. Results: The results of the t-test showed that postural and strength correction exercises had a significant effect on the research variables. In addition, the results of the analysis of variance test showed that there is a significant difference between the control group and the two training groups in all variables, but between the two groups of postural correction and strength correction exercises on the variables examined in this research, it was not statistically significant. Conclusion: The results of the research showed that doing sports exercises had a significant effect on reducing the complications related to chronic neck pain in this research, so it is possible to use sports exercises to improve the condition of neck pain in people with neck pain problems, and on the other hand, the cost reduced the treatment..
