title: Neuroleptic-induced "painful legs and moving toes" syndrome: successful treatment with clonazepam and baclofen.
abstract: The syndrome of "painful legs and moving toes" is characterised by spontaneous causalgic pain in the lower extremities associated with peculiar involuntary movements of the toes and feet. It has been observed after a variety of lesions affecting the posterior nerve roots, the spinal ganglia and the peripheral nerves. The pathophysiology of the syndrome is unknown. I report a patient who developed the syndrome during treatment for schizophrenia with the antipsychotic agent molindone hydrochloride. The patient's response to the combination of clonazepam and baclofen suggests that the pathophysiology of the "painful legs and moving toes" may be linked to impairment of spinal serotonergic and GABA functions.
