Table 2.

Group means (±1SD) for peak shear force, peak knee extensor moment, anterior tibial translation and lateral tibial translations. Group means (±1SD) for the low and high stratification also provided within each column.

Peak Shear F (N) Peak ATT (mm) Peak LTT (mm)
Group
 Mean (±1SD) -526.2 (258.3) 4.6 (1.7) 0.4 (1.0)
Low Knee Shear F Group (n = 5)
 Mean (±1SD) -320.4 (258.3) 5.6 (2.4) 0.4 (1.0)
High Knee Shear F Group (n = 5)
 Mean (±1SD) -814.9 (254.4) 3.9 (0.9) 0.7 (1.1)
Comparison of Low vs High Knee Shear F Groups p = .02 p = .18, β = .14 p = .66, β = .07
Peak Ext Moment (Nm) Peak ATT (mm) Peak LTT (mm)
Group
 Mean (±1SD) 121.5 (44.4) 4.6 (1.7) 0.4 (1.0)
Low Knee Ext. Moment Group (n = 5)
 Mean (±1SD) 82.3 (11.3) 3.7 (0.8) 0.2 (1.3)
High Knee Ext. Moment Group (n = 5)
 Mean (±1SD) 172.8 (32.0) 4.4 (1.3) 0.2 (1.0)
Comparison of Low vs High Knee Ext Moment Groups p < .0001 p = .34, β = .17 p = .99, β = .05

p-values represent t-tests between low and high group stratifications (peak shear, peak knee extensor moment) and within each column heading. When not significant, post-hoc power analysis were conducted (β = values).
