Introduction: It is common in patients with Chronic Obstructive Pulmonary Disease (COPD) to present extrapulmonary complications, such as muscle dysfunction that causes peripheral weakness and end up compromising the quality of life of these individuals. Objective: In this way, the objective of this study was to evaluate and verify the relationship between the peripheral muscle strength of the upper limb and dominant lower limb with the maximum respiratory pressures, as well as the heterogeneity between the dominant limbs. Methods: It was an observational, analytical and cross-sectional study. Fourteen volunteers with COPD, aged 40 to 80 years, of both sexes, who underwent hand hydraulic dynamometry to measure palmar grip strength, were used to compute the force of the dominant quadriceps muscle and for maximal inspiratory and expiratory pressure used the digital manovacuometer. We used the Shapiro-wilk tests and the Pearson correlation test, with a significance level of 5% being assigned. Results: The mean values obtained for the palmar grip strength were 38Kgf, the peak torque was 115Nm, the maximum inspiratory pressure was 74.5cmH2O and the maximum expiratory pressure was 119.7cmH2O. A strong and direct correlation (r = 0.8 and p = 0.001) between peak torque and manual grip was observed. Conclusion: There is a correlation between the peak torque of the quadriceps and the maximum manual grip strength, in addition to a difference between the peripheral forces, the lower limb being more affected compared to the upper limb.
