Figure 3

Comparisons of dyspnea during various external vibrations. (A) Dyspnea sensations were shown as a function of inspiratory resistive loads imposed externally. Data are mean ±standard errors (SE). The p values among curves were calculated by two-way repeated ANOVA with Fisher’s PLSD post hoc. *p<0.01. The comparison between curves not indicating any symbol means no significant difference. (B) Dyspnea slope calculated by the linear regression when dyspnea Borg scores were plotted as a function of resistive loads. Closed circles and error bars indicate the mean value and SE in each group, respectively. P values were calculated by one-way ANOVA with Fisher’s PLSD post hoc. Comparisons between the groups not indicating p value mean no significant difference.
