  1. (a) Mean Magnitude-Squared Coherence (MSC) between trunk and leg accelerations presented as [25%, 50%, 75%] percentiles for able-bodied (AB) participants and individuals with incomplete spinal cord injury (iSCI) at lower and higher frequencies for different standing conditions as well as between-population Cohen’s d effect size. (b) Between-conditions Cohen’s d effect size for AB and iSCI populations at lower and higher frequencies. (c) Cancellation-index proposed by Kato et al. [30] as an indicator of trunk–leg reciprocal action presented as [25%, 50%, 75%] percentiles for AB and iSCI populations with between-population effect size for each standing condition. Cohen’s d effect size was defined as very small (d = 0.01), small (d = 0.20), medium (d = 0.50), large (d = 0.80), very large (d = 1.20), and huge (d = 2.00)
