Alien Hand Syndrome: A Case Report and Approach to Rehabilitation

Abstract

The Alien Hand Syndrome (AHS) is a phenomenon characterized by involuntary autonomous activity of the affected extremity, perceived by the patient as controlled by an external force. It may result from a number of conditions including brain injury, stroke, tumors and progressive neurological disorders. We report a case of AHS in a 60 year old right handed gentleman admitted with a subarachnoid haemorrhage secondary to a pericallosal aneurysm. He developed involuntary movement of his right hand including excessive grasp reflex and intermanual conflict. The current literature is scarce on specific rehabilitative strategies and therefore a number of approaches were used at different stages. He was noted to make good progress throughout his rehabilitation and by time of discharge his Alien Hand movements were diminished and interfering less in activity performance. The AHS may be under recognized and can hinder rehabilitation if not diagnosed. A number of rehabilitation approaches can be used and significant improvement can be expected.
