Abstract

OBJECTIVES:
Fibromyalgia syndrome (FM) is a complex disease that is mainly characterised by chronic pain, fatigue, and sleep disturbances and may be precipitated or worsened by many stressors. The aim of this study was to examine the effects of respiratory muscle training (RMT) on respiratory efficiency and health-related quality of life (HRQoL) in women with FM.
METHODS:
A total of 30 women with FM were included in the intention to treat analyses: 15 were assigned to the RMT group and 15 to the control group. The intervention consisted of 12 weeks of RMT. The primary outcome was the change in pulmonary function assessed by global body plethysmography at 12 weeks compared with baseline. Secondary outcomes included changes of scores in HRQoL assessed by the Short Form 36 Health Survey-Portuguese version.
RESULTS:
The maximal inspiratory pressure (MIP) improved by 17.5% (p-value = .033), maximal expiratory pressure (MEP) improved 21.6% (p-value = 0.045) and maximum occlusion pressure (P0.1 max) increased 27.7% (p-value = 0.007). HRQoL improved in the dimensions of physical function, physical role, bodily pain and vitality (p-value <0.05).
CONCLUSIONS:
RMT results in a significant improvement of respiratory efficiency and HRQoL after 12 weeks. RMT could be an effective therapy to enhance respiratory function and quality of life in women with FM.
