Proximal Muscle Fatigability

Overview

    • How to Perform

    • Ask the patient to hold their arms above their head for as long as they can.
    • Interpretation

    • Inability to hold this position suggests proximal weakness, though if the patient is initially able to hold their arms up without issues then fatigues, this is a sign of myaesthenia.
