Respiratory Muscle Activity

Background: Body positioning and diaphragmatic breathing may alter respiratory pattern and reduce dyspnoea in people with chronic obstructive pulmonary disease (COPD).Objectives: To determine the effect of positioning and diaphragmatic breathing on respiratory muscle activity in a convenience sample of people with COPD, using surface electromyography (sEMG).Methods: This prospective descriptive study recorded sEMG measurements at baseline, after upright positioning, during diaphragmatic breathing and 5 minutes thereafter. Vital signs and levels of perceived dyspnoea were recorded at baseline and at the end of the study. Data were analysed using repeated measures ANOVAs with post hoc t-tests for dependent and independent variables.Results: Eighteen participants (13 male; mean ± standard deviation age 59.0 ± 7.9 years) were enrolled. Total diaphragmatic activity did not change with repositioning (p = 0.2), but activity increased from 7.3 ± 4.2 µV at baseline to 10.0 ± 3.3 µV during diaphragmatic breathing (p = 0.006) with a subsequent reduction from baseline to 6.1 ± 3.5 µV (p = 0.007) at the final measurement. There was no change in intercostal muscle activity at different time points (p = 0.8). No adverse events occurred. Nutritional status significantly affected diaphragmatic activity (p = 0.004), with participants with normal body mass index (BMI) showing the greatest response to both positioning and diaphragmatic breathing. There were no significant changes in vital signs, except for a reduction in systolic/diastolic blood pressure from 139.6 ± 18.7/80.4 ± 13.0 to 126.0 ± 15.1/75.2 ± 14.7 (p < 0.05).Conclusion: A single session of diaphragmatic breathing transiently improved diaphragmatic muscle activity, with no associated reduction in dyspnoea.Keywords: diaphragmatic breathing, positioning, chronic obstructive pulmonary disease, physiotherapy, electromyography, breathing exercises

Introduction: Chronic Obstructive Pulmonary Disease (COPD) was characteristic by the inflammatory process in the airway which causes air trapping and hyperinflation, then followed by decreasing the respiratory muscle strength. Breathing training using the positive expiratory pressure (PEP) increasing respiratory muscle strength.Methods: A case presentation of a male, age was 60 years old diagnosed as COPD by The Global Initiative for Chronic Obstructive Lung Disease (GOLD) grade 4 group D, and Chronic Heart Failure (CHF) grade II, with complication of excessive phlegm, underweight, and weakness of respiratory muscle, have PEP for 8 weeks.Results: Spirometry evaluation before and after eight week of PEP have found; FEV1 22.12 and 22.42%, FVC 34.24 and 56%, FEV1/FVC 76.8 and 64%. Respiratory muscle strength before and after PEP showed the Muscle Inspiratory Pressure (MIP) 46 and 71 cmH2O, Muscle Expiratory Pressure (MEP) 48 and 104 cmH2O.The values of Six Minute Walk Test (6MWT) evaluation by BORG modified scale before and after PEP were 11 and 13 ( efforts), 2 and 3 (dyspnea), 0 and 1 (Leg Fatigue). The six-minute walking distance (6MWD) before and after PED were 170 and 190 m, equation reference with Nury’s formula showed percentage prediction before and after PEP respectively 29.2 and 32%, VO2Max; 4.96 and 6L, METs; 1.41 and 1.7. The St GeorgeRespiratory Questionnaire (SGRQ) before and after PEP were 20.6 and 49.5% (symptom), 86.6 and 45.1% (activity), 45.5 and 18.4% (impact) and 53.6 and 42% for total.Conclusion: Positive airway pressure exercise had beneficial effect on reducing air-trapping process in COPD and increasing the respiratory muscle strength for both expiratory and inspiratory muscle strength.Keywords: Chronic obstructive pulmonary disease, positive expiratory pressure device, respiratory muscle strength, six minutes walking distance

Most patients with chronic obstructive pulmonary disease (COPD) have impaired respiratory muscle function. Maximal oesophageal pressure correlates closely with exercise tolerance and seems to predict the distance walked during the 6-min walk test. This study assessed the non-invasive parameters of respiratory muscle function in 41 patients with COPD to investigate their relationship to pulmonary function tests and exercise tolerance. The COPD patients, who demonstrated the full range of airway obstruction severity, had a mean forced expiratory volume in 1 s of 42.5% predicted (range, 20–79% predicted). Both the maximal inspiratory muscle strength and non-invasive tension-time index were significantly correlated with the degree of lung hyperinflation, as expressed by the ratio of residual volume to total lung capacity, and the distance walked in 6 min. We conclude that respiratory muscle function was influenced mainly by lung hyperinflation and that it had an important effect on exercise tolerance in COPD patients.
