“…These studies revealed substantial to near-perfect agreement between the goldstandard and alternative manometers during testing with human participants. [18][19][20][21] Importantly, near-perfect agreement was seen even in manometers designed for general (as opposed to respiratory-specific) pressure testing purposes. 19 These studies were important in demonstrating that alternative manometers could be used as a potential substitute to the MicroRPM for respiratory strength testing.…”

Objective(s)This study examined the agreement in maximal expiratory (MEP) and inspiratory (MIP) pressure readings between two digital manometers: (1) the MicroRPM – the gold‐standard manometer for respiratory muscle strength testing; and (2) the LDM – a low‐cost, commercially available, alternative manometer.MethodsPositive (MEP) and negative (MIP) pressures were simultaneously applied to the MicroRPM and LDM using a 3‐liter syringe within a controlled laboratory setting. Pressure readings were compared, and agreement was analyzed using Lin's concordance correlation (ρc). Agreement was interpreted as ‘poor’ if <0.90, ‘moderate’ if 0.90 – <0.95, ‘substantial’ if 0.95 – <0.99, and ‘excellent’ if ≥0.99. Twenty percent of the pressure trials were repeated by a second researcher to examine test–retest reliability.ResultsA total of 150 trials were completed, ranging from −167 to +208 cmH2O. There was a median absolute difference of 0.3 cmH2O in pressure readings between the MicroRPM and the LDM. Lin's concordance correlation revealed ‘excellent’ agreement between the LDM and MicroRPM devices, with test–retest reliability assessment revealing ‘substantial‐to‐excellent’ agreement between the LDM and MicroRPM devices, with a concordance correlation coefficient of ρc = 0.999 (95% CI: 0.999–0.999).ConclusionsThere was a median difference of 1.0% in MEP and MIP pressure readings consistently observed between the LDM and MicroRPM. Despite these relatively small differences, excellent agreement between the two manometers was present. These data suggest the LDM may be a valid, lower cost alternative to the MicroRPM for objectively assessing respiratory strength in clinical practice; however, additional research is needed in healthy adults and in patient populations.Level of EvidenceN/A Laryngoscope, 2023

Introduction Pilates exercise may complement traditional pulmonary rehabilitation in individuals with chronic obstructive pulmonary disease (COPD). The objective was to analyze the effects of adding a six-month Pilates exercise program to a three-month pulmonary rehabilitation for individuals with COPD. Methods Thirty-five participants with COPD (GOLD B) were assigned to the intervention (n=14) or control (n=21) group. Both groups received an initial three months of a pulmonary rehabilitation program. The intervention group further underwent six months of pilates. Participants were evaluated at baseline and at three, six, and nine months. Lung function and strength of respiratory muscles were defined as primary outcomes. Secondary outcomes included cardiac, physical function, and exacerbation episodes. Results There were no consistent statistically significant differences between groups for the lung function outcomes (p<0.05). Maximal inspiratory and expiratory pressure increased significantly at three months in both groups (p<0.05). It was significantly superior in the intervention group at nine months for maximal inspiratory pressure (p=0.005) and six and nine months for maximal expiratory pressure (p=0.027 and p<0.001, respectively). Changes in muscle strength (knee extension and handgrip) were comparable between groups (p>0.05), but exercise-induced fatigue and balance were significantly superior in the intervention group at the six- and nine-month follow-ups (p<0.05). Discussion Pilates exercise programs may be implemented to augment traditional pulmonary rehabilitation with the goal of improving the strength of respiratory muscles. Conclusion Adding a Pilates exercise program to pulmonary rehabilitation resulted in superior strength of respiratory muscles, higher resistance to exercise-induced fatigue, and improved balance.

Introducción: La evaluación de la fuerza de los músculos inspiratorios de forma no invasiva permite detectar su debilidad de manera global. El uso de manómetros digitales o aneroides para conocer la fuerza inspiratoria puede ser tomada por una técnica estática, conocida como pimometría obteniendo la presión inspiratoria máxima. No obstante, también se emplea equipos como el PowerBreathe obteniendo el índice de fuerza, misma que es considerada una técnica dinámica. Métodos: El presente trabajo es un estudio de cohorte transversal, enfocado en analizar la fuerza muscular inspiratoria de manera estática y dinámica en sujetos sanos, utilizando un manómetro digital no clínico Ht - 18909 comparando con un equipo de PowerBreathe. El estudio se realizó en 23 pacientes voluntarios sanos con edad media de 19 años. Resultados: Las mediciones de la fuerza inspiratoria para ambos instrumentos alcanzaron una media de 57,5 cmH2O y 55,3 cmH2O (DE 16,38 - 14,91) al ser tomadas con manometría y equipo PowerBreathe respectivamente, la correlación mediante el cálculo del ICC con una confiabilidad del 95%, fue de 0.87 teniendo un alto nivel de concordancia o similitud entre las medidas. Conclusiones: Se concluyó que no existen diferencias significativas al medir la fuerza inspiratoria al ocupar ambos dispositivos mismos que estiman la fuerza de manera estática y dinámica.
