“…This result is in agreement with the premise that the inspiratory muscles of chronic asthmatic patients are shortened due to hyperinflation, reducing their efficacy (34,35). A Brazilian study assessed the effects of muscle stretching on the MIP and MEP values and found an improvement in respiratory muscle strength following sessions of global posture re-education among healthy individuals (36).…”

OBJECTIVE:Asthma may cause systemic repercussions due to its severity and the effects of treatment. Our objective was to compare posture, balance, functional capacity, and quality of life (QOL) according to the severity of disease, as assessed by pulmonary function levels.METHOD:This cross-sectional study evaluated fifty individuals with asthma. We compared two groups of adult individuals who were divided according to the median of the forced expiratory volume in one second (FEV1) as follows: group A = FEV1>74% predicted; group B = FEV1<74% predicted. All patients underwent the following tests: spirometry, whole-body plethysmography, diffusing capacity for carbon monoxide (DLco), respiratory muscle strength, posture assessment, stabilometry, six-minute walking distance (6MWD), and QOL.RESULTS:All pulmonary function variables exhibited statistically significant differences between the two groups, except for the DLco. The maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), and 6MWD were lower in group B. The maximal mediolateral velocity and the mediolateral displacement were significantly different, while the postural changes and QOL were similar between the groups.CONCLUSIONS:In adult individuals with asthma, the pulmonary function is associated with balance control in the mediolateral direction but does not influence the postural changes or QOL.

“…( 7 , 28 ) However, asthma patients with mild or moderate obstructive lung disease might not have significant lung hyperinflation resulting in changes in diaphragm position. ( 29 , 30 ) The fact that the patients in the present study had moderate airway obstruction might explain why their MIPs and MEPs were similar to those in healthy individuals.…”

“…( 7 , 28 ) Entretanto, os asmáticos com distúrbio ventilatório obstrutivo leve ou moderado podem não apresentar hiperinsuflação pulmonar significativa que altere a posição do diafragma. ( 29 , 30 ) Como os pacientes da presente casuística apresentavam obstrução moderada das vias aéreas, é possível que esse fato justifique a similaridade de seus valores de PImáx e PEmáx com a de indivíduos normais.…”

Six-minute walk test and respiratory muscle strength in patients with uncontrolled severe asthma: a pilot study

et al. 2015

OBJECTIVE: To evaluate respiratory muscle strength and six-minute walk test (6MWT) variables in patients with uncontrolled severe asthma (UCSA). METHODS: This was a cross-sectional study involving UCSA patients followed at a university hospital. The patients underwent 6MWT, spirometry, and measurements of respiratory muscle strength, as well as completing the Asthma Control Test (ACT). The Mann-Whitney test was used in order to analyze 6MWT variables, whereas the Kruskal-Wallis test was used to determine whether there was an association between the use of oral corticosteroids and respiratory muscle strength. RESULTS: We included 25 patients. Mean FEV1 was 58.8 ± 21.8% of predicted, and mean ACT score was 14.0 ± 3.9 points. No significant difference was found between the median six-minute walk distance recorded for the UCSA patients and that predicted for healthy Brazilians (512 m and 534 m, respectively; p = 0.14). During the 6MWT, there was no significant drop in SpO2. Mean MIP and MEP were normal (72.9 ± 15.2% and 67.6 ± 22.2%, respectively). Comparing the patients treated with at least four courses of oral corticosteroids per year and those treated with three or fewer, we found no significant differences in MIP (p = 0.15) or MEP (p = 0.45). CONCLUSIONS: Our findings suggest that UCSA patients are similar to normal subjects in terms of 6MWT variables and respiratory muscle strength. The use of oral corticosteroids has no apparent impact on respiratory muscle strength.

“…This method can provide important information in clinical practice regarding patients with pulmonary and extra-pulmonary diseases [ 2 – 8 ]. Some lung diseases [ 4 – 6 , 8 ], such as asthma and cystic fibrosis, are comorbid with reduced respiratory muscle strength caused by lung function deterioration. The influence of respiratory co-morbitities can produce similar conditions in patients with hematology [ 2 ] and osteomusuclar [ 3 , 7 ] diseases.…”

Reference Equation for Respiratory Pressures in Pediatric Population: A Multicenter Study

et al. 2015

Previous studies have proposed only one prediction equation for respiratory muscle strength without taking into consideration differences between ages in pediatric population. In addition, those researches were single-center studies. The objective of this study was to establish reference equations for maximal inspiratory pressure (PImax) and maximal expiratory pressure (PEmax) in children and teenagers. In a multicenter study, 450 healthy volunteers were evaluated (aged 6–18yrs). There were included volunteers with normal lung function. We excluded volunteers who could not perform the tests; participated in physical activity more than twice a week; were born prematurely; smokers; chronic respiratory, cardiologic, and/or neurologic diseases; had acute respiratory disease during the prior three weeks. The volunteers were divided into two groups: Group 6–11 (6–11yrs) and Group 12–18 (12–18yrs). PImax and PEmax were measured according to statement. The mean PImax value was 85.6 (95%IC 83.6–87.6 cmH2O), and PEmax 84.6 (95%IC 85.5–86.2 cmH2O). The prediction equations for PImax and PEmax for Group 6–11 were 37.458–0.559 + (age * 3.253) + (BMI * 0.843) + (age * gender * 0.985); and 38.556 + 15.892 + (age * 3.023) + (BMI * 0.579) + (age * gender * 0.881), respectively (R2 = 0.34 and 0.31, P<0.001). The equations for Group 12–18 were 92.472 + (gender * 9.894) + 7.103, (R2 = 0.27, P = 0.006) for PImax; and 68.113 + (gender * 17.022) + 6.46 + (BMI * 0.927), (R2 = 0.34, P<0.0001) for PEmax. This multicenter study determined the respiratory muscle strength prediction equations for children and teenagers.
