Abstract

In this paper, maximum inspiratory pressure, maximum expiratory pressure, pulmonary function tests and maximum voluntary ventilation in primary fibromyalgia patients with chest pain were evaluated. Patients without any complaint of dyspnoea were selected. Fifty-nine fibromyalgia patients and 42 healthy controls were studied. Patients with fibromyalgia had lower maximum inspiratory pressure, maximum expiratory pressure, and maximum voluntary ventilation values than controls. Chest pain was assessed according to visual analog scale (VAS) score. There was no significant difference between groups in spirometric values, age and body mass index. The duration of fibromyalgia was 3.8 ± 4.4 years (1–15 years). Although the exact mechanism is not known, the results indicate that reduced respiratory muscle strength may be related to chest pain in fibromyalgia patients in the absence of dyspnoea.
