2008 American Physical Therapy The patient was referred to a neurologist, who diagnosed serotonin syndrome related to the use of citalopram. The patient was weaned off citalopramand made a successful recovery, with scores on the Oswestry Disability Indexdecreasing from 70% to 28% at discharge from the physical therapy treatment and to0% at the 6-month follow-up. The patient has since returned to her prior activity level,which includes skiing, motorcycle riding, and working at her consulting firm.
Discussion. This case report demonstrates how careful evaluation by the physical
therapist indicated that signs and symptoms were not consistent with fibromyalgia,
and further medical evaluation revealed the actual diagnosis of serotonin syndrome.
