SpletThe shoulder joint-related dynamic control ratio (DCR) is derived by dividing the peak eccentric moment of the external rotators (ER) by the peak concentric moment of the internal rotators (IR). However, given the inherent limitation associated with a single value DCR, an alternative approach is to calculate it at fixed angular intervals. SpletThe therapist should stabilize the test arm at the shoulder. To Test Instruction to the patient should be given in the language they are comfortable with. The Patient moves the arm in the available range of internal rotation (backward and upward). Complete available range of motion and hold maximum resistance for grade 5.
