Clenched fist syndrome: a case report.

While this was a complex case with some clinical uncertainty regarding the cause of our patient's symptoms, we conclude that psychological processes were central to the development of his clenched fists. The phenomenon of clenched fists and our case are discussed with reference to the accumulated literature on psychogenic hand disorders and the International Statistical Classification of Diseases and Related Health Problems, 10th version. The nosological status appears to be obscure. This case presentation is a first step in increasing the understanding of this syndrome from a psychiatric perspective.
