Table 2. Group differences in MVICs and tVAF1 between DMD and TD from the MWU-test (α = 0.01) and their r effect sizes.

Values are given in medians and 25th and 75th centiles.

Abbreviations in alphabetic order: DF = dorsiflexion; DMD = Duchenne muscular dystrophy; KE = knee extension; KF = knee flexion; MVIC = maximal voluntary isometric contraction; MWU = Mann-Whitney U; Nm·kg-1 = Newton meters per kilogram body weight; PF = plantar flexion; TD = typically developing; tVAF1 = total variance accounted for by one synergy.
