RESULTS

The two factor ANOVA (Factor A = Yoga versus Control groups and Factor B = before versus after) revealed significant differences (P<.001, all cases) for both factors as well as the interaction between them (A X B), for "in" and "out" trials, calculated separately. See Fig. 1 for group average values of the degree of illusion ("di" ), in mm. The Tukey test results are summarized in Table 1.

Fig. 1: Group average degree of illusion ("di" in mm) in yoga (Y) and control (C) groups at initial (1) and final (2) assessments, during both "In" and "Out" trials. ** = P< 0.001, Tukey test (Y2 versus Y1, or Y2 versus C2, or Y2 versus C1). The standard deviation (SD) values for the Y group at 1 and 2 testings were 1.4 and 1.0, respectively, for both trials. For the C group the SD values at 1 and 2 assessments were 1.7 and 1.5 respectively ( " In trials" ) and 1.1 and 1.9 respectively ( "out trials" )
