Supraspinatous Tendonitis

The torque curve is usually flattened during the concentric phase of either internal or external rotation (dependent on the position of the humorous).

If the test is performed in 90 degrees of abduction (lying position) then the curve will be flattened in the latter half of internal rotation see next figure.

If the test is performed in any other position the curve will be flattened in the external rotation component see next figure.
