  • 상지의 외전에 따른 관절와상완운동 및 견갑흉곽운동은 전체적으로 1.6:1의 비율로 일어나고 있었으며 외전초기에는 주로 관절와상완관절에서 운동이 일어나고 외전후기에는 관절와상완운동보 다도 견갑흉곽운동에서 약간 더 많은 운동이 일어 남을 알 수 있었다. 상지가 외전시 외회전운동은 약 70도정도가 일어나 상당히 많은 양의 외회전이 일어나고 있음을 알 수 있었으며 이 외회전운동은 외전초기에는 완만하게 일어나다 외전후기에 주로 일어나고 있음을 관찰할 수 있었다. 외전하는 동안 상완골두의 상방전위는 90도까지 3mm로 일정하게 일어나다 그 후로는 하방으로 다시전위되어 최대외전에서는 전위의 변화가 거의 없었으며 이 전위는 견봉상완간격의 변화와 밀접한관계가 있음을 알 수 있었다. 그러나 본 연구는 이차원적인 견관절운동에 대한 연구로 이를 참조하여 추후 삼차원적인 입체적 분석 및 다양한 방향에서의 견관절운동에 대한 좀 더 많은 연구와 관심이 필요할 것으로 사료되었다.

  • Purpose: This study examined the effects of early stabilization exercise focused on the scapulothoracic joint on the recovery of surgical patients due to rotator cuff tear. Methods: The subjects were 30 patients divided randomly into two groups. Group I consisted of 15 patients who practiced shoulder joint stabilization exercises, including glenohumeral joint movement. Group II consisted of 15 patients who practiced scapulothoracic joint stabilization exercises, excluding glenohumeral joint movement. The duration of stabilization exercise was 30 minutes for one day, five days a week, and five weeks. To measure the dependent variables, the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, range of motion (ROM), dynamometer of measured grip were used. Results: The DASH, ROM, and grip power were compared. A significant difference was observed before the intervention in each group (p<.05), and there was no significant difference between group I and group II (p>.05). Conclusion: Both shoulder joint and scapulothoracic joint stabilization exercises were effective after the intervention compared to preintervention, but there was no difference between the two groups. Unlike many recent studies on the initiation of stabilization exercises, this study allays the concerns between the advantages of 'early exercise' and oppositions of previous studies about 'early exercise'. Nevertheless, further research regarding these subjects is needed.

  • 평균 나이 23세.의 건강한 남자 31명을 대상으로 하여 측각도계즐 이용한 견관절운동역을 측정한 결과 Dominant arm과 Non-dominant arm 모두에서 능동운동역에 비해 수동운동역이 증가되었고, 능동운동시 견갑외전, 중립신전, 수평신전, 수평굴곡, 그리고 중립 및 수평내회전에서, 수동운동의 격우에는 견갑외전, 수평굴곡, 그리고 중립 및 수평내회전에서 Non-dominant arm의 운동증가를 보였고, 수평외회전의 경우 Dominant arm의 운동증가소견을 보였다(p〈0.05) .또한 방사선투시기를 이용하여 관절와상완각과 견갑흉곽각의 비(θGH/θST)를 측정해 본 결과 첫째로 Dominant arm과 Non-dominant arm에서 모두 완전거상시 관절와상완각과 견값흥곽각의 비(θGH/θST)는 1.6이었으며 60도이상 150도 거상때까지 지속적으로 견값흉곽운동 분율이 커지는 양상이었다. 둘째천 30도에서 완전거상시까지 운동분율(θGH/θST)은 Dominant arm과 Non-domlnant arm에서 각각 1.2 및 1.3으로 나타났다. 견갑사위는 중립위에서 약 42도였고 거상에 따라 점차 작아졌으며 완전거상시에는 약 20도로 측정되었다. 이렇게 해서 얻어진 방사선조사 각도는 단순방사선 촬영에 적용하여, 견관절 질환 치료 후 운동범위의 회복의 경과를 판정하는데 도움을 줄 수 있을 것으로 생각되었다.

  • This study was performed to evaluate the influences of the passive glenohumeral rotation on the scapulothoracic motion. We took anteroposterior radiograms of the right shoulders including the thoracic vertebrae with supine position in 10 normal male adults, at 0 degree abduction, 45 degrees abduction and 90 degrees abduction in scapular plane and in neutral rotation, maximal internal rotation and maximal external rotation in each abduction view. The scapulothoracic motion was measured as the distances between the vertical line drawn from the spinous process of the 7th cervical vertebra and the inferior and superior angles of the right scapula respectively. At 0 degree abduction, the distances were not changed in internal rotation relative to neutral rotation, but decreased significantly in external rotation, that is, the scapula shifts medially on external rotation. At 45 degrees abduction, the distances were increased significantly only in internal rotation, that is, the scapula shifts laterally on internal rotation. At 90 degrees abduction, the scapula rotated laterally on internal rotation and medially on external rotation. In conclusion, when a physician examines the rotation of the shoulder joint, he cannot exclude the scapulothoracic motion just by examining the patient with supine position. And we concluded that the rotatory movement of the shoulder is not solely contributed to the glenohumeral motion.

  • Purpose : To describes the important aspects of scapular movement and function used when applying PNF technique to the upper limb and scapular. Method : The scapular was a very important roles in the upper limb movement. This study summarizes the physiologic movement of scapular to the PNF upper extremity patterns or scapular patterns. Result : The shoulder joint has the most freedom of range of motion in the human body, composed of the glenohumeral joint, the subacromial joint, the acromioclavical joint, the sternoclavicular joint, the scapulothoracic joint, the costosternal joint, and the costovertebral joint. During upper limb movement, the scapular position change at the sternoclavicular joint and the acromioclavical joint. This concerted motion was characterized by scapulohumeral rhythm. In clinical situations, it is import to understand factors affect the scapulohumeral rhythm so that optimal evaluation and therapeutic intervention can be devised. Conclusions : The scapular movement depend on the proper and coordinated contraction of muscles. Physical therapists need to understand the normal scapular movement relationships of the scapulohumeral rhythm under different interventions for PNF techniques application.

  • PURPOSE: The aim of this study was to investigate the effects of distal movement on shoulder muscle activation during diagonal pattern of exercises. METHODS: Seventeen healthy male participants volunteered to participate. Five muscles of shoulder were investigated during standing performance of diagonal shoulder exercises with and without visual trace. Two patterns of the diagonal exercises were used as diagonal 1 flexion and extension (D1F-E), and diagonal 2 flexion and extension (D2F-E). Two way repeated measures analysis of variance was used, which the factor was the presence of distal movement and exercise variations. RESULTS: The average muscle activity values of the lower trapezius and anterior deltoid are higher with the D2F-E, compared to the D1F-E (p<.05). The distal movement effect was observed within included all muscles except the lower trapezius, which the values are significantly greater in exercise with distal movement (P<.05). All significant increase of the muscles during the exercise with distal movement condition showed over 0.9 for the observed power in present study. CONCLUSION: Present result suggested that the diagonal pattern of exercise with distal movement has additional advantages of activating the scapulothoracic muscle as well as glenohumeral muscles. In addition, the D2F-E exercise pattern is effective for activating lower trapezius and anterior deltoid muscles.

  • Background: Limitations of shoulder range of motion (ROM), particularly shoulder internal rotation (SIR), are commonly associated with musculoskeletal disorders in both the general population and athletes. The limitation can result in connective tissue lesions such as superior labrum tears and symptoms such as rotator cuff tears and shoulder impingement syndrome. Maintaining the center of rotation of the glenohumeral joint during SIR can be challenging due to the compensatory scapulothoracic movement and anterior displacement of the humeral head. Therefore, observing the path of the instantaneous center of rotation (PICR) using the olecranon as a marker during SIR may provide valuable insights into understanding the dynamics of the shoulder joint. Objects: The aim of the study was to compare the displacement of the olecranon to measure the rotation control of the humeral head during SIR in individuals with and without restricted SIR ROM. Methods: Twenty-four participants with and without restricted SIR ROM participated in this study. The displacement of olecranon was measured during the shoulder internal rotation control test (SIRCT) using a Kinovea (ver. 0.8.15, Kinovea), the 2-dimensional marker tracking analysis system. An independent t-test was used to compare the horizontal and vertical displacement of the olecranon marker between individuals with and without restricted SIR ROM. The statistical significance was set at p < 0.05. Results: Vertical displacement of the olecranon was significantly greater in the restricted SIR group than in the control group (p < 0.05). However, no significant difference was observed in the horizontal displacement of the olecranon (p > 0.05). Conclusion: The findings of this study indicated that individuals with restricted SIR ROM had significantly greater vertical displacement of the olecranon. The results suggest that the limitation of SIR ROM may lead to difficulty in rotation control of the humeral head.
