Comparison of the co-contraction index (CI). Significant differences between the young and elderly groups are indicated by asterisks (* p < 0.05, ** p < 0.025, *** p < 0.017). Significant differences between the FR and LT conditions are indicated by daggers ( p < 0.05, †† p < 0.025, ††† p < 0.017). Significant differences between the FR and DO conditions are indicated by double daggers ( p < 0.05, ‡‡ p < 0.025, ‡‡‡ p < 0.017). Significant differences between the LT and DO conditions are indicated by section signs (§ p < 0.05, §§ p < 0.025, §§§ p < 0.017). [FR, no supporting structure; LT, light touch of the index finger to a supporting structure (to touch in force < 1 N); DO, dependence on a supporting structure for stabilization as desired]
