Results: While both the EC and FC tests activated supraspinatus to levels approximately 90% of their maximal voluntary contraction, eight other shoulder muscles were also activated to similarly high levels including other rotator cuff muscles (infraspinatus and upper subscapularis), scapular positioning muscles (upper, middle and lower traps, and serratus anterior), and abduction torque producing muscles (anterior and middle deltoid).
