p-Value corrected (q-value) from the three-way repeated-measures ANOVAs and effect size (Cohen’s d). Significance was set at p ≤ 0.05 and corrected with the false discovery rate procedure for multiple comparisons (q ≤ 0.05). Negative/positive values indicate downward/upward velocities and backward/forward velocities; q-values are in bold when significant. * Metacarpophalangeal joint. ** Uninterpretable effect due to a body implication/touch interaction.
