SA muscle weakness leads to changes in the movement of the scapula, resulting in shoulder pain and delayed movement, being one of the causes of scapular dyskinesis. Therefore, scapular protraction exercises have been suggested for weakness of SA, as a way to strengthen it. Previous studies have mentioned that scapular protraction exercises are effective in increasing SA muscle activity. In particular, push-up plus exercise along with scapular protraction exercise was found to be more effective than the conventional push-up because it increases SA activity while minimizing the activity of the upper trapezius (UT). Previous studies suggested that 120° forward flexion is combined with scapula protraction, scapular upward rotation and posterior tipping contributing to increased SA muscle activity. Moseley et al. stated that 95% of the maximum muscle strength of SA occurs when the angle of shoulder flexion is between 120° and 150°.

The participants’ pain intensity was measured using the visual analogue pain scale. Disability was measured using the Korean Oswestry Disability Index. A force measurement device was used to collect data on gluteal muscle strength. The participants walked for five minutes at a preferred walking speed on a treadmill, and the average walking speed was measured during gait and then re-measured after exercise. Results Pain intensity and disability were found to significant decrease after sling and common exercise groups. Significant increased post-intervention versus pre-intervention were seen in the hip abductor strength and gait velocity ( p <0.05). No significant differences were seen in the hip extensor strength ( p >0.05). These results show that hip abductor strength was significantly different between before and after sling exercise. Conclusions Sling exercises may be effective for stability during the gait pattern and may be recommended to improve the gluteal strength and lumbo-pelvic stability for those with chronic low back pain.","PeriodicalId":102754,"journal":{"name":"Journal of Musculoskeletal Science and Technology","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130766330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because hip joint and pelvis move sequentially during hip flexion, clinicians commonly attempt to detect the onset of pelvic rotation when measuring the range of hip flexion, or to limit pelvic movement when measuring hamstring muscle length. However, previous studies have demonstrated concurrent movement of the femur and pelvis, posterior tilting of the pelvis, and flattening of the lumbar spine during hip flexion; collectively, these movements are termed pelvifemoral rhythm. The contribution of pelvic rotation to hip flexion onsets at a very early point and then persists throughout the range of hip flexion. Thus, clinicians must consider simultaneous pelvifemoral rhythm when measuring the range of hip flexion or hamstring muscle length. In previous studies, pelvic motion accompanying hip flexion was analyzed using various tools, including tape lines or tape markers, spherical reflective markers, 8, 10 and magnetic sensors.

The curvature of the thoracic vertebrae generally increases with age, and in recent years, the hyperkyphosis is frequently observed between the 20s and 50s while using digital devices such as computers and smartphones. Thoracic hyperkyphosis reduces balance and increases the risk of falls. In addition, musculoskeletal problems such as neck pain, shoulder pain, and back pain are also associated with thoracic hyperkyphosis. It is important for physical therapist to measure thoracic kyphosis because thoracic hyperkyphosis have negative health consequences. The Cobb angle calculated by sagittal plane spinal radiograph is considered the gold standard in thoracic kyphosis measurements. However, the limitations of radiographic measurements are cost, portability limitations, time consuming, and exposure to ionizing radiation. For this reason, non-radiological methods are preferred in clinical settings, and Spinal Mouse, Flexicurve and Arcometer has previously demonstrated excellent level of validity and intra-inter-rater reliability in previous studies.

In scapular elevation syndromes, LS shortening acts as a major factor in abnormal movement of the scapula.
