Fig. 4.

Dominant EDC, compared to the non-dominant side shows significantly greater excitability in shoulder ADD. a Shows single-pulse data from EDC MEP area (uV.ms, rescaled, see METHODS) of dominant compared to non-dominant side in ADD and ABD. Mixed model estimated means and SEM are shown for all figures. ***indicates p < 0.001. b FDS shows no significant difference between sides whether the UE is positioned in ADD or ABD. Although separate models were run for ADD and ABD, notice that non-dominant EDC excitability increases in moving from ADD to ABD but there is no significant difference between dominant and non-dominant EDC excitability when either UE is in ABD
