| 1 | Assessment of scapulohumeral rhythm for scapular plane shoulder elevation using a modified digital inclinometer显示文摘AIM: To develop a better understanding of scapulohumeral rhythm during scapular plane shoulder elevation.METHODS: Thirteen healthy, college-aged subjects participated in this study. Subjects were free from any upper extremity, neck or back pathology. A modified digital inclinometer was utilized to measure scapular upward rotation of the subject's dominant shoulder. Upward rotation was measured statically as subjects performed clinically relevant amounts of shoulder elevation in the scapular plane. Testing order was randomized by arm position. Scapular upward rotation was assessed over the entire arc of motion and over a series of increments. The percent contributions to shoulder elevation for the scapula and glenohumeral joint were calculated. Scapulohumeral rhythm was assessed and represented the ratio of glenohumeral motion to scapulothoracic motion(glenohumeral elevation: scapular upward rotation). A one-way ANOVA wasused to compare scapular upward rotation between elevation increments.RESULTS: Scapulohumeral rhythm for the entire arc of shoulder elevation was equal to a ratio of 2.34 :1 and ranged from 40.01:1 to 0.90:1 when assessed across the different increments of humeral elevation. Total scapular motion increased over the arc of shoulder elevation. The scapula contributed 2.53% of total motion for the first 30 degrees of shoulder elevation, between 20.87% and 37.53% for 30o-90 o of shoulder elevation, and 52.73% for 90o-120 o of shoulder elevation. Statistically significant differences in scapular upward rotation were identified across the shoulder elevation increments [F(3,48) = 12.63, P = 0.0001].CONCLUSION: Clinically, we must recognize the usefulness of the inclinometer in documenting the variable nature of scapulohumeral rhythm in healthy and injured shoulders. | Jason S Scibek Christopher R Carcia | 2012 | World Journal of Orthopedics2012，3，6： | 2 |

| 11 | Collecting shoulder kinematics with electromagnetic tracking systems and digital inclinometers: A review显示文摘The shoulder complex presents unique challenges for measuring motion as the scapula,unlike any other bony segment in the body,glides and rotates underneath layers of soft tissue and skin.The ability for clinicians and researchers to collect meaningful kinematic data is dependent on the reliability and validity of the instrumentation utilized.The aim of this study was to review the relevant literature pertaining to the reliability and validity of electromagnetic tracking systems(ETS) and digital inclinometers for assessing shoulder complex motion.Advances in technology have led to the development of biomechanical instrumentation,like ETS,that allow for the collection of threedimensional kinematic data.The existing evidence has demonstrated that ETS are reliable and valid instruments for collecting static and dynamic kinematic data of the shoulder complex.Similarly,digital inclinometers have become increasingly popular among clinicians due to their cost effectiveness and practical use in the clinical setting.The existing evidence supports the use of digital inclinometers for the collection of shoulder complex kinematics as these instruments have been demonstrated to yield acceptable reliability and validity.While digital inclinometers pose a disadvantage to ETS regarding accuracy,precision,and are limited to twodimensional and static measurements,this instrument provides clinically meaningful data that allow clinicians and researchers the ability to measure,monitor,and compare shoulder complex kinematics. | Daniel C Hannah Jason S Scibek | 2015 | World Journal of Orthopedics2015，6，10： | 0 |
