Abstract
Abstract
Introduction: Complications of abnormalities caused by muscle imbalance following incorrect body positions related to people's jobs are one of the biggest occupational health problems. Therefore, the aim of the present study was to compare the forward head angle and range of motion of the shoulder joint in hairdressers with chronic neck pain and healthy ones.
Research method: In the present comparative causal research, 90 female beauticians in the age range of 20-45 years, according to the inclusion and exclusion criteria of the research, were purposefully selected and randomly divided into two groups of 45 people (with chronic neck pain, healthy). Body profile imaging was used to evaluate head forward deformity, neck pain intensity was used using VAS scale, and goniometer was used to evaluate range of motion of the shoulder joint. Kolmogorov-Smirnov test was used for normality of data and independent t-test was used to compare variables in two groups. All statistical calculations were used in SPSS software version 24 at a significance level of 0.05.
Results: There was a significant difference in the forward head angle in two groups of hairdressers with chronic neck pain and healthy (P=0.05). Also, there was a significant difference between the range of motion of external rotation of the shoulder joint and the range of motion of abduction of the shoulder joint in the two groups in both dominant and non-dominant hands.
conclusion: According to the results of this research regarding the effect of chronic neck pain on the reorganization of movement control strategies and the change in the pattern of muscle abundance and its effect on the surrounding soft tissues and joint muscles, it can be concluded that due to the common muscle connections of the neck and shoulder, it causes Muscle imbalances in the upper quadrant during work and changes in the craniovertebral angle and limiting the range of motion of the shoulder joint.
