You are examining a patient's response to passive limb movement. Before revealing the answer, decide what distinguishes Gegenhalten (opposition) from Mitmachen and Mitgehen.

Ask how the limb responds to passive movement: does it resist with a force that matches the examiner's, does it move with unusual, exaggerated ease regardless of instruction, or does it offer essentially no resistance at all? Gegenhalten (opposition) is resistance to passive movement that specifically matches the degree of force applied by the examiner, so gentle movement may meet little resistance while firmer movement meets firm resistance. Mitmachen and Mitgehen sit at the opposite end of the same spectrum: in Mitmachen the patient's limb can be moved into any position with minimal instruction despite being told to resist, and in Mitgehen, its more extreme form, even the lightest touch produces exaggerated movement in the direction of the pressure, with no resistance offered at all.
