“…It is known from previous studies that patients with shoulder pathologies have pain, altered scapular control, and/or muscle imbalance. 9,14,16,17,24,27,37,40,43,46,54,55,57 Therefore, scapular kinematics and muscle activity occurring with the retraction exercises may differ in individuals with pre-existing shoulder injuries and scapular dysfunction. Therefore, caution needs to be taken when applying the results of this study to pathologic population.…”

“…12,13) Recent studies using electromagnetic sensor-based motion analysis devices have reported that the scapular kinematics of impingement syndrome patients (excluding rotator cuff tears) involve a significant decrease in motion compared to that of healthy individuals. [14][15][16] Studies analyzing the scapular kinematics of rotator cuff tear patients have reported a significant increase in the scapular motion compared to that in healthy individuals; 17,18) however, there are far fewer reports on rotator cuff tear patients than on impingement syndrome patients. Moreover, the tear size in the subjects of the reported studies was limited to small to medium tears; to our knowledge, there are no such studies on MRCTs.…”

Objective: Rotator cuff tears can influence shoulder kinematics and severely impair function. However, there have been no studies on three-dimensional (3D) shoulder kinematics in massive rotator cuff tear (MRCT) patients. Hypothesizing that MRCT patients could demonstrate significantly changed scapular kinematics during arm elevation in the scapular plane, we compared 3D scapular kinematics in the scapular plane between MRCT patients and healthy elderly subjects. Methods:We assessed 15 shoulders of 11 MRCT patients and 16 shoulders of 16 healthy subjects. With the subjects seated, we used an electromagnetic tracking system to calculate the upward rotation, posterior tilt, and internal rotation of the scapula at 10° increments from 30° to 120° with respect to the thorax. We performed two-way analysis of covariance with the initial position of the scapular motion as the covariate and performed multiple comparisons using the Bonferroni method. Results: MRCT patients exhibited significantly higher scapular upward rotation than did the healthy subjects (P < 0.05). There were no significant differences between groups with regard to posterior tilt and internal rotation. Conclusions: This study indicated that when MRCT patients elevated their arms, they exhibited a significantly higher scapular upward rotation at low-to mid-range elevations compared with that of healthy subjects. This difference may have resulted from a compensatory effect in response to the decreased elevation torque caused by the loss of rotator cuff function. These results may assist rehabilitation strategies to improve active arm elevation in MRCT patients.

“…12 Several investigations have aimed to determine if adaptations in scapular movement occur in individuals with impingement or rotator cuff disease. [17][18][19][20]22,[25][26][27]29 A narrative review of studies assessing scapular kinematics by Ludewig and Reynolds 15 noted some consensus among adaptations found in individuals with impingement or rotator cuff disease. Specifically noted were decreased scapular movement toward upward rotation, posterior tilt, and external rotation during humeral elevation.…”
