Introduction: Breast cancer is a major cause of morbidity and mortality, leading to functional deficiencies in ventilation, muscle performance, balance and posture.Objective: To describe the effects of the muscle energy technique (MET) for quadratus lumborum on maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) in patients with stage I and II breast cancer.Materials and methods: Quasi-experimental study with a pretest-posttest design conducted in 10 patients treated at a highly specialized healthcare center in Bogotá. Physical therapy assessment and three physiotherapy sessions with the MET to measure MIP and MEP were carried out before and after the intervention using a respiratory pressure meter.Results: The average MIP was 41% of the reference value at the beginning of the intervention, which increased to 69% at the end of the sessions. On the other hand, the initial average MEP was 33%, while the post-intervention average MEP was 51%. The average change rate for MIP was 68% and 57% for MEP. The Wilcoxon signed-rank test was performed, achieving a statistically significant difference (z=-2.807, p=0.005).Conclusion: Applying the MET on the quadratus lumborum muscle improves its performance and increases respiratory muscle strength.

Objective. The present study compared the effects of upright and slouched sitting postures on the respiratory muscle strength in healthy young males. Methods. A total of 35 adult male subjects aged 18–35 years participated in this study. Respiratory muscle strength was determined by measurement of sniff nasal inspiratory pressure (SNIP) using a MicroRPM device in the upright and slouched sitting positions. The subjects were asked to perform the pulmonary function test including peak expiratory flow (PEF), forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and FEV1/FVC ratio at baseline. Body composition was also determined. Results. There was a significant difference of SNIP score between upright sitting and slouched sitting positions (p=0.04). The mean difference of SNIP score between upright sitting and slouched sitting positions was 8.7 cmH2O. Significant correlations were found between SNIP in upright sitting and FEV1% predicted values [R = .651], SNIP in slouched sitting and FEV1% predicted values [R = .579], and SNIP in upright sitting and SNIP in slouched sitting positions [R = .926] (p<0.05 for all). There were no significant correlations between SNIP scores, demographic variables, and other baseline clinical data (p>0.05). Conclusions. The slouched sitting position had a lower SNIP score compared to upright sitting position suggesting a reduced diaphragm tension and movement as a result of altered body posture.

Introduction: Manual therapy uses the hands as a form of healing, being a manipulation for therapeutic purposes. However, there is little evidence of its effects on the respiratory system. Objective: To describe the effect of manual therapy on the diaphragm, on respiratory muscle strength and on the mobility of the thoracic cavity. Method: Descriptive, longitudinal, interventional and quantitative research, performed at the Cardiopneumofunctional Physical Therapy Laboratory of the Federal University of Ceará (UFC). The sample consisted of 40 sedentary female students, aged between 18 and 35 years of the Physiotherapy course of the UFC. The following techniques were performed: “diaphragm lift” and double diaphragm. Data collection was performed in three steps, on the same day and by the same researcher, under a homogeneous verbal command. It was considered statistically significant value of p≤0,05. Results: After applying the techniques, a comparative analysis was performed, which demonstrated a statistically significant difference in the maximum expiratory pressure, with p< 0,0001, and all the coefficients of the cirtometry, being p<0,0025 (axillary), p<0,0085 (xiphoid) and p<0,0005 (basal). Conclusion: Manual therapy techniques performed on the diaphragm exert an influence on muscle strength due to the increase in maximum expiratory pressure and in the mobility of the thoracic cavity, reflected in the increase of the coefficients of the cirtometry.

Abstract Inspiratory muscle training (IMT) is a strategy that has been used to improve performance in different sports modalities. This study investigated the effects of an IMT program on respiratory muscle strength and resistance as well as aerobic physical performance (PP) of handball athletes. Nineteen 20 ± 3 year-old male athletes were allocated into an experimental (EG, n = 10) or a placebo group (PG, n = 9). Their respiratory muscle strength was evaluated by measuring the maximum inspiratory and expiratory pressures (MIP and MEP), muscular respiratory resistance by maximum voluntary ventilation (MVV) and aerobic PP by the cardiopulmonary exercise test. The study was designed to evaluate the effects of a 12-week IMT program with five sessions a week. A significant difference was observed in the pre and post IMT values of the MIP (170 ± 34 to 262 ± 33 cmH2O) and MEP (177 ± 36 to 218 ± 37 cmH2O) in the EG, and MIP (173 ± 45 to 213 ± 21 cmH2O) in the PG, with a large effect size for the MIP, when the groups were compared. MVV showed a significant increase (162 ± 24 to 173 ± 30 L) in the EG, with a small effect size. There was a significant difference in maximum oxygen uptake (54 ± 8 to 60 ± 7 ml/kg/min) in aerobic PP. Oxygen uptake at the respiratory compensation point (RCP) (46 ± 6 to 50 ± 5 ml/kg/min), with a moderate effect size for both variables, was observed in the EG after IMT. We concluded that IMT provided a significant increase in respiratory muscle strength and resistance, contributing to increased aerobic PP in the EG, which suggests that IMT could be incorporated in handball players’ training.

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.

Background:Pulmonary and respiratory muscle function impairment are common in patients with Parkinson's disease (PD). However, dyspnea is not a frequent complaint among these patients, although it is well documented that the intensity of dyspnea is related to the activity and the strength of the respiratory muscles.Patients and Methods:We studied pulmonary function, respiratory muscle strength and endurance and the perception of dyspnea (POD) in 20 patients with PD (stage II and III Hoehn and Yahr scale) before and after their first daily L-dopa dose. Respiratory muscle strength was assessed by measuring the maximal inspiratory and expiratory mouth pressures (PImax and PEmax), at residual volume (RV) and total lung capacity (TLC) respectively. The POD was measured while the subject breathed against progressive load and dyspnea was rated using a visual analog scale.Results:Respiratory muscle strength and endurance were decreased and the POD was increased during the off medication period compared to normal subjects. There was a nonsignificant trend to an increase in PImax, PEmax and endurance after L-dopa intake. The POD of PD patients decreased (p<0.05) following medication, although, it remained increased (p<0.01) as compared to the normal subjects. Even if patients had spirometry data showing a mild restrictive pattern, before medication, both forced vital capacity (FVC) and forced expiratory volume (FEV)1 remained almost identical after L-dopa intake.Conclusions:Patients with PD have higher POD, compared to normal subjects and this increased perception is attenuated when the patients are on dopaminergic medication. The change in the POD is not related to changes in respiratory muscle performance or pulmonary functions. A central effect or a correction of uncoordinated respiratory movements by L-dopa may contribute to the decrease in POD following L-dopa treatment.

Background: The use of evaluation tools such as the manovacuometer and respirometer is frequent and disinfection is usually limited to the external surfaces, which is insufficient and raises concerns because of the potential spread of infectious diseases. Hydrophobic heat and moisture exchangers (HME) are used in mechanical ventilation and have microbiological filters, which can possibly reduce contamination, increasing the safety of related procedures. It is unknown, however, if the addition of an exchanger affects the measurements obtained. Aim of this study was to verify if the use of an HME interferes in maximal inspiratory and expiratory pressures assessed using the manovacuometer and vital capacity evaluated using the respirometer in healthy adults. Methods: A controlled transversal trial was carried out. Twenty healthy young adults were included in the study. Vital capacity by respirometer and, maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) were assessed with and without the use of HME. Results: No significant difference was found between the values pre and post HME use in vital capacity measurements: (3878.8 ± 202.2 mL vs. 3925.5 ± 206.0 mL, p = 0.116) and the respiratory muscle strength measurements: MIP (−99.0 ± 8.9 vs −95.5 ± 9.0 cm H2O, p = 0.149) and MEP (92.5 ± 7.5 vs 92.5 ± 7.7 cm H2O, p = 1.0) respectively. Conclusion: We conclude that the use of HME does not modify the lung volumes or respiratory muscle strength, and can be used in order to reduce the occurrence of pulmonary infection.

Introduction Individuals with Down syndrome may have decreased respiratory muscle strength due to hypotonia, a common characteristic in this population. Objective To analyze the effects of a hippotherapy program on respiratory muscle strength in individuals with Down syndrome. Materials and methods The study included 41 subjects, 20 of which were in the hippotherapy practicing group (PG) and 21 of which were in the non-practicing group (NPG). Study subjects were of both sexes, aged 7-13 years, and all diagnosed with Down syndrome. A manovacuometer was used to measure respiratory muscle strength, following the protocol proposed by Black and Hyatt (23). Statistical analysis was performed by means of descriptive distribution. After verifying normality and homoscedasticity of the variables, the Mann-Whitney test was used to determine differences between the means of the two groups (PG and NPG), and the Spearman’s rank correlation coefficient test was used to view possible relationships with age and time practicing hippotherapy. Significance was set at p < 0.05. Results and discussion Individuals who practiced hippotherapy showed improvements in both inspiratory and expiratory respiratory muscle strength, although no significant difference was demonstrated. Conclusion This study demonstrates that hippotherapy benefits respiratory muscle strength in individuals with Down syndrome, and that the youngest subjects had the best results.

The Relationship

Introduction: The aim of this study is to investigate the relationship between shooting performance and pulmonary functions and respiratory muscle strength in archers. Material and methods: The research was conducted with 31 boy and 11 girl archers aged 9-12. The forced vital capacity (FVC), forced expiration volume in one second (FEV1), FEV1/FVC, peak expiratory flow (PEF), maximum voluntary ventilation (MVV), maximum inspiratory pressure (MIP), and maximum expiratory pressure (MEP) of the archers were measured. To determine the shooting performance, a total of 30 shots (15+15) were taken from an 18-meter distance in closed shooting range. Results: A significant difference was found between the 15 shots done in each half and the total shot point and the averages of FVC (r=0.375, 0.353, 0.378 respectively) and FEV1 (r=0.368, 0.339, 0.367 respectively). However, a significant difference was not found among these shot points and other respiratory parameters (p>0.05). A relationship was detected between the second 15-shot points of boy archers and MEP (r=0.370). Conclusions: A strong correlation was not found between the respiratory parameters and shooting performances of the archers in this study. However, it is thought that this level of relationship will rise as training level and age increases.
