OBJECTIVE: To assess the outcome of fibromyalgia syndrome (FMS) after cervical spine injury.
METHODS: Seventy-eight of 102 (77%) patients with neck injury were recruited 3 years after the original study in 1996. Twenty of the original 22 patients with FMS were available for reevaluation in 1999. A count of 18 tender points was conducted by thumb palpation, and tenderness thresholds were assessed by dolorimetry at 9 tender sites. All patients were interviewed about the presence and severity of neck and FMS-related symptoms. FMS was diagnosed by using the American College of Rheumatology 1990 criteria. Additional questions assessed measures of physical functioning and quality of life.
RESULTS: Sixty percent of the 20 patients who had FMS in 1996 still had it 3 years later. All the 11 women with FMS, but only 1 of the 9 men with FMS, met FMS criteria in 1999. Only 1 of 58 patients who had no FMS in 1996 developed FMS. The quality of life scores for most patients improved, their tenderness scores decreased, and all remained employed.
CONCLUSIONS: The outcome of posttraumatic FMS in patients with neck injury seems to be more favorable in men than in women; however, this finding should be interpreted with caution because of the small sample. Patients who do not develop FMS within 1 year of neck injury have a low probability of developing FMS in the future, comparable to the incidence of FMS in the general population.
