    Objective: To assess the agreement between MIP measurement devices and investigate the distribution another indices of inspiratory muscle function obtained by digital device in a healthy sample. Method: Cross-sectional and prospective study conducted with healthy individuals, aged 20 to 85 years, both sexes, non-smokers and non-obese. MIP was measured using an analog and digital device to assess association and agreement between measurements using intraclass correlation coefficient and Bland Altman test, respectively. A direct comparison of MIP values with values predicted in equations referenced in literature was performed. Inspiratory muscle work, strength-index (s-index) and inspiratory muscle resistance measured also by digital device were correlated with demographic, anthropometric and spirometric variables and multiple linear regression test was applied to assess the ability to predict and develop reference equations. Results: One hundred and fiftythree individuals were recruited, but only 120 were included for analysis, most woman,with no previous history of smoking and medium level of physical activity. MIP values obtained by the digital device were, on average, 6.8 cmH2O higher than the analog, with high variability of the differences. For this sample, PImax prediction formulas present in literature, overestimated the values when strength was lower, and underestimated when PImax was high. New PImax prediction formulas were presented for each device. Height and MIP obtained on the digital device are the variables that best explain inspiratory muscle work (-755 + MIP * 3.33 + height * 5.32), and height, weight, age and sex are the ones that predict the values obtained for the S-index (Man:-32.3 - 0.39 * age + 0.79 * height + 0.47 * weight; Woman: -53 -0.39 * age + 0.79 * height + 0 , 47 * weight). Conclusion: Digital device presented higher and discordant MIP values when compared to analog device. Prediction equations for MIP, S-index and inspiratory muscle work were also presented.
