Explain why Mitgehen is considered a more extreme variant of Mitmachen rather than a wholly separate phenomenon.
Mitmachen and Mitgehen share the same underlying pattern: a lack of the expected resistance to passive movement despite an explicit instruction to resist, followed by the limb returning to its resting position once released. What separates them is purely a matter of degree, specifically how little force is needed to produce the response. Mitmachen requires the examiner to actually move the limb, whereas Mitgehen requires only the lightest conceivable touch, such as a single finger, to produce movement in the direction of that pressure. Because the underlying mechanism and the return-to-rest pattern are identical, and only the threshold of triggering pressure differs, Mitgehen is best understood as an extreme point on the same continuum as Mitmachen rather than a distinct sign in its own right.
