Objective. - To examine the possible relationship between chest expansion

and pulmonary muscle strength in patients with primary fibromyalgia (PFM).

Methods. - Forty-one consecutive women with PFM were compared with age and

body mass index matched 40 healthy women concerning pulmonary function

tests, chest expansion, and maximum respiratory pressures indicating

pulmonary muscle strength, and endurance (MVV). Pain was scored according

to a visual analog scale (VAS). Chest pain was scored on a 10 point scale.

Results. - There was no significant difference between the two groups

regarding chest expansion (P > 0.05). Maximum inspiratory and expiratory

pressures (MIP, MEP) were lower in fibromyalgia patients than controls (P <

0.05). However, chest expansion and dyspnea score were insignificant

between groups (P > 0.05).

Conclusion. - Reduced maximum respiratory pressures (MIP, MEP) may result

from isometric type pulmonary muscle dysfunction as a result of low

physical performance in fibromyalgia patients, despite insignificant

finding of chest expansion and dyspnea score according to controls.
