The probability of finding MPs plotted in the areas (1–48), presented with a 95% CI. The dark red areas (4,9,10,16,29) display a statistically significant higher probability of finding MPs compared to the shades of yellow, green and gray/white areas. The orange areas (14,32) display a statistically significant difference compared to the green and grey/white areas. The grey/white areas did not display a MP. MP Motor Point, CI Confidence Interval. Area 1 = medial, proximal. Area 48 = distal, lateral
