Table 1. Association strengths between binary features and target outcomes using Cramer’s V.

The Cramer’s V analysis demonstrates the varying strengths of association, between the stimulation location features and the movement outcome. Results demonstrate that the tactile, distal location of stimulation feature, had higher association for both binary-class and multi-class outcomes, compared to ANC and tactile, proximal part features.

Categorical Variables	Binary Target (Cramér’s V Value)	Multi-Class Target (Cramér’s V Value)
Stimulation: ANC	0.175	0.177
Stimulation: Tactile, distal part	0.435	0.500
Stimulation: Tactile, proximal part	0.287	0.373
