Participants underwent MTS assessment using both devices. Reliability was assessed through intraclass correlation coefficients, while concurrent validity was evaluated through Pearson correlation and Bland\u2013Altman analysis. Effect size (Cohen\u2019s\n d<\/jats:italic>\n ) was used to assess discriminative ability. Measurement time was compared using a paired\n t<\/jats:italic>\n test, and multivariable regression was conducted to assess demographic associations.\n <\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n Both CUPTI and IOPI demonstrated excellent test\u2013retest reliability (ICC > 0.95). CUPTI consistently recorded lower MTS values, with a mean bias of \u20138.12 kPa (limit of agreement: \u20132.52 to 18.76 kPa). A strong correlation (\n r<\/jats:italic>\n = 0.93,\n P<\/jats:italic>\n < 0.001) was observed between devices. The effect size of 0.61 indicated a moderate, clinically meaningful difference. CUPTI required slightly more time than IOPI for MTS assessment (\n P<\/jats:italic>\n = 0.005). Age was the only significant predictor of MTS (\n P<\/jats:italic>\n = 0.034).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n CUPTI is a valid and reliable alternative to IOPI, offering affordability and accessibility for clinical and community dysphagia screening. Its performance supports implementation in resource-constrained settings and home-based rehabilitation.<\/jats:p>\n
