About

this study aims to assess the gluteus maximus muscle electromyographic activity and the latissimus dorsi muscle electromyographic activity in patients with shoulder impingement syndrome , to improve the assessment procedure and the rehabilitation program for treating patients with shoulder impingement syndrome more effectively. .

Full description

background: Shoulder pain is the third most common musculoskeletal complaint that can lead to disability that interfere with work, hobbies, social, and sporting activities and may also be associated with psychological distress and reduced quality of life .Shoulder impingement syndrome Symptoms is the most common cause of shoulder pain.

Normal shoulder movement is achieved through a stable lumbopelvic-hip complex and scapula. Thus, the pelvis must provide a stable platform for the scapula and the scapula provide a stable platform for the shoulder. The existing evidence supports myofascial biomechanical connection between lumbopelvic region and contralateral glenohumeral joint .So Considering the LP region and related myofascial force transmission as contributing factors for shoulder pathogenesis can explain the reasoning on why some of the patients with shoulder pain may progress to develop chronic shoulder pain.

purpose: this study aims to assess the gluteus maximus muscle electromyographic activity and the latissimus dorsi muscle electromyographic activity in patients with shoulder impingement syndrome , to improve the assessment procedure and the rehabilitation program for treating patients with shoulder impingement syndrome more effectively.

methods: This study is a cross sectional comparative study will be conducted at the out-patient physical therapy clinic, Pharos University in Alexandria, Egypt. 30 patients with unilateral shoulder impingement and 30 healthy controls without shoulder impingement , with age range between 25 and 40 years will be included in the study. All patients will be referred by an orthopedic surgeon.

results: data analysis with one-way ANOVA will be used to compare between subjects characteristics of the two groups and un-paired t-test will be used to compare measured variables between groups.
