Arm posture influences on regional supraspinatus and infraspinatus activation in isometric arm elevation efforts
Alenabi, Talia; Whittaker, Rachel; Kim, Soo Y.; Dickerson, Clark R. (Elsevier, 2019-02)This study aimed to evaluate the effect of arm posture on activation of the anterior and posterior regions of supraspinatus and the superior and middle regions of infraspinatus during resisted isometric arm elevations. ... -
Maximal voluntary isometric contraction tests for normalizing electromyographic data from different regions of supraspinatus and infraspinatus muscles: Identifying reliable combinations
Alenabi, Talia; Whittaker, Rachel; Kim, Soo Y.; Dickerson, Clark R. (Elsevier, 2018-08-01)This study aimed to identify optimal sets of maximal voluntary isometric contractions (MVICs) for normalizing EMG data from anterior and posterior regions of the supraspinatus, and superior, middle and inferior regions of ...
