Normalized torque values for the control group (HG) and the idiopathic scoliosis group (ISG). Torque normalized to lean body weight for the control group (HG, n = 26) and the idiopathic scoliosis group (ISG, n = 14). Significant p-values for within group differences are presented at the base of the graph. Significant p-values for between group differences are shown above the values with brackets indicating which values were analyzed. Specifically HG left compared to ISG concave in the 36 Low force and 18 Low force contractions.
