“…20 We also noticed a remarkable improvement in static respiratory pressures MIP (or PImax) and MEP (or PEmax). Besides, MIP is more sensitive parameter than vital capacity during respiratory muscle weakness 16 There are very few studies on effect of yoga on static respiratory pressures. And almost none in India especially in Kerala.…”

Introduction: Chronic obstructive pulmonary disease (COPD) being a major public health problem, pulmonary rehabilitation along with pharmacotherapy can give better results while managing COPD. Almost no studies have been done to assess the relationship between effect of yoga as an adjunctive therapy on respiratory function in COPD patients especially in south India. This study was an attempt to know the effect of selected Yogic practices on improving respiratory function. Material and methods:A total of 30 cases of mild, moderate and severe grades of COPD defined as per Global Initiative for obstructive lung disease (GOLD) guidelines were recruited in this study. The sample size was taken as 30. All selected subjects were assessed for spirometric evaluation, Maximum inspiratory pressure MIP (or PImax) and Maximal expiratory pressure MEP (or PEmax). Patients were taught selected yoga exercises for 1 hour, thrice a week for one month by a certified yoga therapist. Thereafter, patients were asked to practice at home in the morning for two months. Statistical analysis was performed using a statistical software package SPSS version 20.0. Comparison of pre-yoga and post-yoga assessment of respiratory function at the end of each month for two months was done. Continuous variables were expressed as Mean±SD. Effect of yoga on selected parameters at different interval of time were assessed by paired t test. P<0.05 was taken to be statistically significant.Results: FEV1%, PEFR, FVC, FEV1/FVC, showed an increasing trend over time from pre-yoga to 1 month and preyoga to 2 month, among which FEV1% and FEV1/FVC was statistically significant at p <0.05. Likewise, variables PEFR also showed a significant increase from pre-yoga to end of 2nd month (p<0.05).Conclusion: yoga practices is suggestive of improving respiratory function in COPD patients when used adjunctively with standard pharmacological treatment.How to cite this article: Jessy John, P.

PurposeThe Test of Incremental Respiratory Endurance (TIRE) provides a comprehensive assessment of inspiratory muscle performance by measuring maximal inspiratory pressure (MIP) over time. The integration of MIP over inspiratory duration (ID) provides the sustained maximal inspiratory pressure (SMIP). Evidence on the reliability and validity of these measurements in COPD is not currently available. Therefore, we assessed the reliability, responsiveness and construct validity of the TIRE measures of inspiratory muscle performance in subjects with COPD.Patients and methodsTest–retest reliability, known-groups and convergent validity assessments were implemented simultaneously in 81 male subjects with mild to very severe COPD. TIRE measures were obtained using the portable PrO2 device, following standard guidelines.ResultsAll TIRE measures were found to be highly reliable, with SMIP demonstrating the strongest test–retest reliability with a nearly perfect intraclass correlation coefficient (ICC) of 0.99, while MIP and ID clustered closely together behind SMIP with ICC values of about 0.97. Our findings also demonstrated known-groups validity of all TIRE measures, with SMIP and ID yielding larger effect sizes when compared to MIP in distinguishing between subjects of different COPD status. Finally, our analyses confirmed convergent validity for both SMIP and ID, but not MIP.ConclusionThe TIRE measures of MIP, SMIP and ID have excellent test–retest reliability and demonstrated known-groups validity in subjects with COPD. SMIP and ID also demonstrated evidence of moderate convergent validity and appear to be more stable measures in this patient population than the traditional MIP.

“…In addition, dyspnea, one of the most important consequences of imbalance between respiratory muscle strength and load, 38 is an important factor for limitations in ADL. 10 Khalil et al 39 showed that the P Emax is correlated with dyspnea and functional exercise capacity. Expiratory muscle strength was found as a factor that influences ADL in subjects with COPD.…”

Factors Influencing Activities of Daily Living in Subjects With COPD

BACKGROUND: Activities of daily living (ADL) are important for an independent life. As COPD progresses, the ability to complete ADL is usually reduced. Knowing the possible factors that influence the ability to perform ADL may allow better targeting of appropriate rehabilitation programs to increase the independence levels and/or to prevent further decreases in patients with COPD. Therefore, the aim of this study was to investigate ADL performance as measured by the London Chest Activity of Daily Living scale, which is a commonly used measure in patients with COPD. METHODS: This cross-sectional study included 44 clinically stable subjects who were not taking antibiotics and had not made any changes in their medications for at least three weeks with a COPD diagnosis based on Global Initiative for Chronic Obstructive Lung Disease. Demographic characteristics, pulmonary function, ADL measured by the London Chest Activity of Daily Living scale, functional exercise capacity via the 6-min walk distance, disease-related symptoms measured by the COPD Assessment Test, and peripheral and respiratory muscle strength were evaluated. A multiple linear regression (stepwise) analysis was used to determine the variables that have the greatest influence on ADL (ie, the London Chest Activity of Daily Living scale score). RESULTS: The London Chest Activity of Daily Living scale score had moderate correlations with the COPD Assessment Test score (r ‫؍‬ 0.31, P ‫؍‬ .041), maximum expiratory pressure value (r ‫؍‬ ؊0.37, P ‫؍‬ .01), 6-min walk distance (r ‫؍‬ ؊0.48, P ‫؍‬ .001), knee extensor muscle strength (r ‫؍‬ ؊0.47, P ‫؍‬ .001), handgrip strength (r ‫؍‬ ؊0.44, P ‫؍‬ .003). The 6-min walk distance, COPD Assessment Test score and maximal expiratory pressure values were significant and independent determinants of the London Chest Activity of Daily Living scale, with 40.1% of the variance in subjects with COPD. CONCLUSIONS: Functional exercise capacity, disease-related symptoms, and expiratory muscle strength have the greatest influence on ADL in the subjects with COPD. The level of independence to perform ADL can be increased by improving functional exercise capacity, reducing symptoms, and increasing expiratory muscle strength in subjects with COPD.
