The application of dynamic integrated EMG and motion analysis to the shoulder has improved the understanding of dynamic shoulder biomechanics during athletic activities and rehabilitation protocols. These studies exemplify a symbiotic merger of basic science research and clinical application. EMG and motion analysis has produced specific objective quantifiable data concerning the muscles in and about the shoulder during normal planar motion, athletic motions, and rehabilitation exercises. This expanded understanding of intricate muscular interrelationships during athletic activities and rehabilitative exercises has not only complemented clinical awareness of subtle shoulder anomalies but helped to develop logical preventative exercises, surgical procedures, and rehabilitation protocols, all of which are based on sound scientific principles. Comprehension of the normal intermuscular interdependence during the previously mentioned activities has led us to investigate common athletic shoulder disorders. It is hoped that application of the normal EMG and motion analysis to the pathologic state will enable us to suggest new ideas concerning the pathomechanics of these disorders, as well as propose future treatment and rehabilitation of these maladies. The specific emphasis in this article has been the role of integrated EMG and motion analysis in the evaluation of athletic activities and rehabilitation exercises. It is hoped that knowledge of these investigations will increase the clinician's basic understanding of the biomechanics of the shoulder and aid in his or her clinical evaluation, treatment, and subsequent rehabilitation of the shoulder.
动态集成肌电图与运动分析在肩部的应用，增进了我们对运动活动及康复方案中肩部动态生物力学的理解。这些研究例证了基础科学研究与临床应用的共生融合。肌电图与运动分析已得出有关肩部及其周围肌肉在正常平面运动、体育动作和康复锻炼过程中的具体客观可量化数据。对运动活动和康复锻炼过程中复杂肌肉相互关系的深入理解，不仅补充了对肩部细微异常的临床认识，还有助于制定基于合理科学原则的合理预防锻炼、手术程序和康复方案。对上述活动中正常肌肉间相互依存关系的理解，促使我们研究常见的运动性肩部疾病。希望将正常的肌电图和运动分析应用于病理状态，能使我们就这些疾病的发病机制提出新观点，并为这些疾病的未来治疗和康复提出建议。本文的具体重点是集成肌电图和运动分析在评估运动活动和康复锻炼中的作用。希望这些研究成果能增进临床医生对肩部生物力学的基本理解，并有助于其对肩部进行临床评估、治疗及后续康复。
