Opposing muscle ratios. Opposing muscle ratio. This is the ratio between the measured trunk strength rotating towards the midline (high force contraction) and the trunk strength rotating away from the midline (low force contraction) while in the same pre-rotated trunk position. Ratios in the neutral position for both HG (n = 26) and ISG (n = 14) were significantly lower than all other values (p < 0.001). Eighteen degree (18°) ratios for the ISG were significantly lower than the same side 36° ratios (p < 0.01). P-values for between group differences are presented at the base of the graph. The significant side difference is presented using a bracket to identify the values used, with the p-value shown on top. [* Significantly higher than the neutral position; ** significantly higher than the neutral and 18° positions (on the same side)]
