Mean difference represents the difference over time at T1, T2, and T3 compared to baseline (T0). p values were obtained using Paired samples t-test. Significant differences are presented in bold (p < 0.05) and tendencies are presented in italic (0.05 < p < 0.075). *Some participants were excluded (see degrees of freedom) due to technical problems with the IWW and/or video footage
