Revision of the Shoulder Normalization tests is required to include rhomboid major and teres major.

The four "Shoulder Normalization Tests" were found previously to be a parsimonious set of isometric tests that produce maximal voluntary isometric contractions (MVIC) in the supraspinatus, infraspinatus, subscapularis, trapezius, serratus anterior, deltoid, latissimus dorsi, and pectoralis major [Boettcher et al. (2008). J Orthop Res 26:1591-1597]. However, these tests have not been validated for rhomboid major and teres major.  Ginn KA, Halaki M, Cathers I. J Orthop Res. 2011 Jun 27. doi: 10.1002/jor.21488.
