简要总结
Introduction. Nonspecific low back pain (NSLBP) is a very prevalent medical condition, especially in subjects with chronic obstructive pulmonary disease (COPD).
The diaphragm is a respiratory muscle, but it takes part in trunk stabilization on lumbar spine. NSLBP is related to lack of spinal control. The COPD symptoms include lack of efficiency in diaphragm, which could be connected to NSLBP.
Hypothesis and objectives. COPD can contribute to NSLBP. It is associated with diaphragm weakness, severity of respiratory function, lower level of physical activity and quality of life in COPD.
Methods. A descriptive observational cross-sectional study was conducted with two groups: the first one with subjects with COPD and the second one with subjects without it. Data were collected on: pulmonary function; respiratory muscles strength; trunk postural control; quality of life with COPD; physical activity level; lumbar pain presence, intensity and disability. Data were collected in a single session.
详细描述
Introduction/Background. Nonspecific low back pain (NSLBP) is a very prevalent medical condition (84% of the general population has suffered from it throughout its lifetime). Its prevalence stands out in individuals with respiratory disease, especially in subjects with chronic obstructive pulmonary disease (COPD).
Even if there are many theories that create a relationship between the two clinical conditions (such as inflammation associated with smoking), the postural control one is quite impressive.
The diaphragm is the main muscle of breathing with its inspiratory function, but it takes part in trunk stabilization on lumbar spine. NSLBP is related to lack of spinal control. The COPD symptoms include lack of efficiency in diaphragm (deformation, weakness and fatigability), which could be connected to NSLBP.
Hypothesis and objectives. The starting hypothesis is that NSLBP is a result of an associated pulmonary disease. COPD can contribute, correlate or even predispose them. NSLBP is associated with diaphragm weakness, severity of respiratory function, COPD severity, lower level of physical activity and quality of life in COPD.
Methods. A descriptive observational cross-sectional study was conducted with two groups: the first one with 67 subjects, diagnosed with COPD, and the second one with 67 subjects without pulmonary disease. Data were collected on: pulmonary function, spirometry; respiratory muscles strength by measuring maximal inspiratory and expiratory pressures (MIP, MEP); trunk postural control by motor control tests (KLAT, ASLR); quality of life with COPD, through the COPD Assessment Test (CAT); physical activity level, using the Modified Baecke Physical Activity Questionnaire (MBPAQ); pain localization, through a body map; pain intensity, using Visual Analogue Scale (VAS) and disability, related to lumbar pain (if there is one), using the Oswestry Disability Index (ODI).
