AimThe frequency of neck pain increases in adolescents and young adults. Using smart phones and computers for a long time causes posture disorders such as rounded shoulder (RSP) and forward head postures, and these posture disorders cause neck pain. The aim of the study is to analyse the correlation between shoulder and neck angles and the stiffness of the upper trapezius and pectoralis minor muscles in patients with RSP.MethodPatients with neck pain examined by shear wave elastography were screened retrospectively. Patients with RSP were determined. Of these patients, whose had evaluated for shoulder and neck angles with a smart phone-based photogrammetric method were assigned. Patients with a history of operation/trauma, connective tissue or neurological disease were excluded. A total of 39 female patients were included in the study. Age, height, weight, elastography measurements, cervical and shoulder angles were noted. Obtained data were statistically analysed with SPSS 22.0 program.ResultsCervical and shoulder angles of the patients were 52.2 ± 3.8 and 57.91 ± 9.4, respectively. The stiffness of the right and left upper trapezius muscles and right and left pectoralis minor muscles were 42.5 ± 14.1, 47.1 ± 17.1, 20.5 ± 8.0 and 17.9 ± 8.4, respectively. In multiple regression analysis, it was observed that the stiffness of the left upper trapezius muscle was positively correlated with the shoulder angle.ConclusionThe upper trapezius muscle stiffness increased in RSP. It can reveal the relationship between RSP and neck pain.© 2021 John Wiley & Sons Ltd.
