Fig. 7

Relative change in the bowknot task (BKT) scores. The graph shows the relative change in the BKT scores. This graph shows the relative change in the BKT scores of P1 and P2 based on the Pre score. The means (±SDs) are shown on the graph. The vertical axis of the graph shows the relative change from Pre. There was a main effect of group (F(4, 28) = 3.792, p = 0.014). Among the groups, VR1 (p < 0.001, d = 3.09) and VR3 (p < 0.001, d = 1.18) showed higher change degrees than the control. There was a main effect of group among the sessions (F(2, 14) = 176.935 p < 0.001). The two-way interaction between group and session was not significant (F(8, 56) = 1.863, p = 0.084)
