Spontaneous limb withdrawal heralding hyperacute stroke or stroke worsening.

Abnormal movements are infrequent presentations in acute stroke.1 However, 3 main presentations have been described as being specific to an acute stroke: limb-shaking, hemichorea-hemiballism, and unilateral asterixis.1 We report an abnormal movement that reminds us of a spontaneous limb withdrawal in 3 patients with hyperacute stroke and stroke worsening.
