A total of 25 participants were enrolled at initial session; however, three participants who did not complete the program because their busy. Therefore, results were recruited 22 participants (88.0%). There were no significant differences in initial characteristic data between those who complete the study program and those who did not (ps > .005). The demographic, cardiorespiratory performance and rate of dyspnea of the hemodialysis patients at baseline and follow-up are shown in table 1.
Paired t-tests was used to compare between initial values and follow-up values in respiratory prototype (table 2); these indicated that respiratory training with TU-Breath Training version II had increased significantly from initial period to the 8 weeks intervention (Δ14.23± 3.44, 95%CI = 7.13 to 21.32, p <.001). The walking distance was also increased in TU-Breath Training group after 8-weeks (Δ20.09 ± 9.10 meters, 95%CI = 1.17 to 39.02, p = .039). Again, the efficacy of TU-Breath Training was reported in increased perceived of dyspnea scores after intervention program (Δ0.50 ± 0.16, 95%CI = 0.17 to 0.83, p = .005).
