| Abstract | ||
| Background: Upper crossed syndrome (UCS) posed a significant health concern in several developed countries. It was considered a work-related musculoskeletal disorder since it led to substantial days off and the associated costs for compensation and disability. purpose: to investigate the correlate between cervicocephalic kinesthesia and electromyographic activity of levator scapulae muscle and pectoralis major muscle in subjects with upper crossed syndrome. Materials and Methods: Thirty-six subjects with upper crossed syndrome recruited to participate in this study; their age ranged from 25 to 45. All subjects’ evaluation included Cervicocephalic kinesthesia by Cervical Range of Motion Instrument (CROM), and Electromyography (EMG) for scapular and shoulder muscles activity. They were randomized into two groups, A and B. Group A included subjects with upper crossed syndrome, while group B included healthy matching subjects without upper crossed syndrome. Results: There was a significant decrease in craniovertebral angle (CVA) has been detected in UCS group in favor of healthy group. On the other hand, there was a significant increase in kyphosis, forward shoulder angle (FSA), flexion joint reposition error (JRE) and extension joint reposition error (JRE) in UCS group compared with healthy subjects (p < 0.05). There was a significant decrease in duration of right and left Levator scapulae muscles of subjects with UCS compared with healthy subjects (p < 0.01), while there was no significant difference in duration of Pectoralis major between groups (p > 0.05). There was a significant decrease in amplitude of right and left Levator scapulae muscles and right and left Pectoralis major muscles of subjects with UCS compared with healthy subjects (p < 0.01). Conclusion: In the current study it was be concluded that the cerviccephalic kinesthesia was affected in subjects with UCS and amplitude of levator scapulae and pectoralis major muscles was affected while only duration of levator scapulae muscle was affected. | ||
