Background: Chronic obstructive pulmonary disease (COPD) is complicated by the presence of frequent and recurrent acute exacerbations. The patients are asymptomatic and stable in the early stages. They develop weakness of primary respiratory muscles and use accessory muscles which lead to postural changes. The forward head posture in the neck is very common in COPD patients due to increased usage of accessory muscles. The respiratory muscle strength is assessed by measuring the Diaphragm excursion. The micro RPM device is also a reliable indicator of respiratory muscle strength. In COPD patients, kinesiotaping has been shown to help stabilize weak neck muscles, correct forward head posture, and thereby enhance diaphragm use. The immediate effects of application of KT on the pulmonary function parameters is not known. Objective: To investigate the immediate effect of kinesiotaping application on pulmonary function test values and respiratory muscle strength in COPD patients and age-matched nonCOPD individuals Methods: The study included 20 COPD and 20 age-matched non-COPD individuals on whom pulmonary function test which included the recording of Forced Vital Capacity (FVC), Forced Expiratory Volume in 1 second (FEV1), and Peak Expiratory Flow Rate (PEFR) using Spirolab device was conducted. The participant's respiratory muscle strength (Maximum Inspiratory Pressure (MIP) and Maximum Expiratory Pressure (MEP) were assessed using Micro Rpm before applying the Kinesio tape (KT). Pulmonary function test and Micro Rpm assessment were repeated after 30 min of applying the KT. The immediate effect of KT on respiratory muscle strength and pulmonary function test values were assessed statistically using Paired ttest or ANOVA in both COPD and non-COPD individuals. To study the association of respiratory muscle strength with anthropometrics and physical activity levels in COD individuals and Pearson's correlation coefficient test was used. Results: KT significantly improved FVC value in COPD patients immediately afte
