Shoulder Rotation Test: A New Test for Discriminating Between Functional and Structural Weakness

Key Points

• The aim is to evaluate the effectiveness of the shoulder rotation test in distinguishing between functional and structural weakness.
• Used shoulder rotation test to assess upper limb weakness.
• Compared responses in cases of functional weakness (FW) and structural weakness (SW).
• Increased impairment in internal rotation (IR) observed in cases of functional weakness.
• IR remained stable in structural weakness cases.
