Fig. 5From: Virtual reality-based action observation facilitates the acquisition of body-powered prosthetic control skillsProtocol. Pre, pre-intervention; S1, Session 1; S2, Session 2; P1, Post 1; P2, Post 2; BBT, Box and Block Test; BKT, bowknot task; AO, action observation. Before the intervention (Pre), the BBT and BKT were used to evaluate prosthetic performance. Then, the participants were divided into five groups (VR1, VR3, Tablet1, Tablet3, and Control) for the intervention. After the intervention, the same evaluation as in the pre-intervention was conducted. Furthermore, with the exception of the control group, immersion during action observation and motor imagery was evaluated. This protocol was repeated twiceBack to article page
