There are few reports of “jumpy stump” and even fewer associated videos. “Jumpy stump” has been used to describe stump tremor, chorea, myoclonus, spasms, jerking, and psychogenic tremor. Despite a common label, the broad phenomenology and inconsistent therapeutic successes in published cases of “jumpy stump” suggest different etiologies. Although the term “jumpy stump” has traditionally been accepted as an organic peripherally induced movement disorder, we caution against the uncritical acceptance of this condition as organic. We present a case of psychogenic “jumpy stump.”
