Electromyographic analysis of the infraspinatus and scapular stabilizing muscles during isometric shoulder external rotation at various shoulder elevation angles
[Purpose] This study aimed to clarify activation of the infraspinatus and scapular stabilizing muscles during shoulder external rotation at various shoulder elevation angles. [Subjects] Twenty subjects participated in this study and all measurements were performed on the right shoulder. [Methods] Isometric shoulder external rotation strength and surface electromyographic data were measured with...
متن کاملElectromyographic analysis of selected shoulder muscles during a rugby football
Background: Epidemiological studies have shown that the incidence of shoulder injuries is increasing in rugby and the majority are related to the contact/tackle phase of play. However, no data currently exists that describes preparatory muscle activity during tackle. This information could aid in guiding training and rehabilitation, if available. The purpose of the study was to assess the seque...
متن کاملElectromyographic analysis of the rotator cuff and deltoid musculature during common shoulder external rotation exercises.
STUDY DESIGN Prospective single-group repeated-measures design. OBJECTIVES To quantify electromyographic (EMG) muscle activity of the infraspinatus, teres minor, supraspinatus, posterior deltoid, and middle deltoid during exercises commonly used to strengthen the shoulder external rotators. BACKGROUND Exercises to strengthen the external rotators are commonly prescribed in rehabilitation, b...
متن کاملElectromyographic Analysis of the Shoulder Girdle Musculature During External Rotation Exercises.
BACKGROUND Implementation of overhead activity, a key component of many professional sports, requires an effective and balanced activation of the shoulder girdle muscles, particularly during forceful external rotation (ER) motions. PURPOSE To identify activation strategies of 16 shoulder girdle muscles/muscle segments during common shoulder ER exercises. STUDY DESIGN Descriptive laboratory ...
متن کاملComparison of electromyographic activity of shoulder muscles during two different pull-up test methods
Pull-up and modified pull-up tests are frequently used for shoulder muscles endurance evaluation by physical educators. Despite of using these tests, the difference of muscle activation pattern in pull-up and modified pull-up tests has not been documented clearly. However, the role of some important muscles such as anterior deltoid, posterior deltoid, trapezius and latissimus dorsi have no...
