“…We think that the explanation given by the examiner or the adherence of the examinee had the greatest influence. In addition, based on the study by Dassios et al [ 16 ], the maximal static pressure measured in patients with cystic fibrosis and healthy subjects can differ because of the testing device or the test method. However, estimating only the examiner or subject variables is incorrect.…”

ObjectiveTo evaluate respiratory muscle strength in healthy Korean children in order to establish the criteria for normal reference values for future applications. In contrast with the other parameters for testing pulmonary function, normal values for respiratory muscle strength in healthy Korean children have not been assessed to date.MethodsWe conducted a complete survey of 263 students at Sinmyung Elementary School in Yangsan, Gyeongsangnam-do, and measured their height and body weight, performed pulmonary function tests, and evaluated maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) as measures of respiratory muscle strength. We excluded the subjects with respiratory or cardiovascular diseases that could affect the results. The subjects were children aged 8–12 years, and they consisted of 124 boys and 139 girls.ResultsThe MIP and MEP values (mean±standard deviation) for the entire subject group were 48.46±18.1 cmH2O and 47.95±16 cmH2O, respectively. Boys showed higher mean values for MIP and MEP in every age group. Korean children showed lower mean values for MIP and MEP compared to those in previous studies conducted in other countries (Brazil and USA).ConclusionOur results showed that boys generally have greater respiratory muscle strength than girls. We found a significant difference between the results of our study and those of previous studies from other countries. We speculate that this may be attributed to differences in ethnicity, nutrition, or daily activities.

“…IT is used to indicate the muscular strength of muscles used in the respiratory system as pressure values. The size of the device is length 60 mm× height 170 mm×width 26 mm, and it weighs 175 g. It has a measurement pressure range of ±300 cmH 2 O, and an accuracy of ±3% for its error range [21]. This device intuitively displays a specific value, but the instrument must be reset and the intermediate filter must be replaced each time the inlet/outlet of air pressure is measured.…”

Objective: This study was conducted to identify the clinical usefulness, validity, and reliability of the Spirokit, a device that combines the pulmonary function test (PFT) and respiratory muscle strength (RMS) test. Design: Cross-sectional study. Methods: Forty young adults (male: 23, female: 17) participated in a PFT and a RMS test. The concurrent validity for pulmonary function was assessed by comparing data obtained from MicroQuark and the Spirokit and the agreements between the MicroRPM and the Spirokit for RMS were compared. The test-retest reliability of the Spirokit was determined by comparing data obtained from the first and second sessions. The test and retest were performed at the same time after one day for the PFT and RMS test. Validity was estimated using intraclass correlation coefficients (ICCs), and by calculating 95% limits of agreement (LoA). To estimate interrater reliability, ICCs were calculated. Results: The Spirokit showed a high agreement intra class coefficient (ICC [2, 1]): 0.978-0.999, 95% limits of agreements (95% LOA): −0.798 to 0.847 with MicroQuark. It also showed a high level of concordance ICC (2, 1): 0.992 to 0.993, 95% LOA: −9.313 to 11.169 with MicroRPM. The test-retest reliability of the Spirokit was analyzed using ICC (2, 1), and showed a high level of reliability (ICC [2,1]=0.960 to 0.998). Standard error of measurement % (SEM%) was 0.12% to 3.39%, and minimum detectable change% (MDC%) was 0.02% to 3.79%, indicating high level of reliability. Conclusions: The Spirokit is a device with high validity and reliability that can be used to simultaneously measure PFT and RMS tests.

“…Assessing respiratory muscle strength provides a new perspective on possible causes of unexplained dyspnea and inefficient cough [ 4 ]. However, as clinical assessment of respiratory muscle strength is difficult, there is a need for objective quantitative measurements [ 5 ]. There are multiple tools for assessing respiratory muscle strength in the literature, which can be categorized as invasive or non-invasive [ 6 ].…”

Background Chronic obstructive pulmonary disease (COPD) is a heterogeneous lung condition, yielding various respiratory symptoms and categorized under several descriptors: early, mild, young, pre-COPD, and preserved ratio impaired spirometry. COPD is synonymous with symptoms such as dyspnea and cough, in addition to others like exercise intolerance, which result from respiratory muscle weakness. Therefore, the emergence of respiratory strength assessment tools for such patients is not surprising. However, evidence is limited regarding the impact of respiratory muscle strength on the physical performance of COPD patients. Therefore, this study employs the MicroRPM device (Medikart HealthCare Systems Pvt. Ltd., Delhi, India) to measure maximum inspiratory and expiratory pressure utilizing mouth pressure. Methodology We recruited a total of 40 patients for the study. All patients received a thorough assessment for hemodynamic stability and were categorized according to the Global Initiative for Chronic Obstructive Lung Disease criteria of COPD. The patients then underwent a training session for the MicroRPM device. We took each patient’s inspiratory and expiratory pressure measurements, then determined their six-minute walk distance and modified the Borg scale rating. Results We observed no significant correlation between maximum inspiratory pressure (Pimax) and six-minute walk distance (r=−0.023, p=0.890) or modified Borg scale (r=−0.044, p=0.788); additionally, the correlation between maximum expiratory pressure (Pemax) and modified Borg scale was not significant (r=−0.192, p=0.235). However, the correlation between Pemax and six-minute walk distance was both negative and significant (r=−0.384, p=0.014). Conclusion Based on our results, respiratory muscle strength can influence the aerobic performance of COPD patients.
