Experimental evaluation of the impact of sEMG interfaces in enhancing embodiment of virtual myoelectric prostheses

Table 2 ANOVA test for embodiment metrics

Variable	Sensors	Delay	Sensors \(\times\) Delay
VPE	p = 1.0, F < 0.0001	p = 1.0, F < 0.01	p = 1.0, F < 0.01
Embodiment	p \(=\) 0.012, F = 6.38	p = 0.139, F = 2.19	p = 0.048, F = 3.9
Ownership	p \(=\) 0.016, F = 5.86	p = 0.571, F = 0.32	p = 0.692, F = 0.16
Location	p \(=\) 0.736, F = 0.11	p = 0.06, F = 3.56	p = 0.072, F = 3.28
Agency	p \(=\) 0.064, F = 3.48	p = 0.679, F = 0.17	p = 0.0612, F = 3.55

Note that VPE refers to Virtual Arm Proproception Error, and Embodiment, Ownership, Location and Agency are the subjective embodiment scores from the questionnaire (Longo et al. [34])
