Abstract
<p><strong>Background:</strong> Trunk flexion and axial extension are characteristic symptoms of chorea–acanthocytosis (ChAc).</p><p><strong>Phenomenology Shown:</strong> A 41-year-old male with ChAc (confirmed by <em>VPS13A</em> mutations) reported that his involuntary axial movements were significantly ameliorated by either folding his arms over his chest or putting his hands behind his head.</p><p><strong>Educational Value:</strong> These apparent “sensory tricks” suggest a dystonic pathophysiology, and also merit further study to analyze their potential for symptom control in ChAc.</p>
