a
Values are expressed as mean (95% confidence interval). Bolded values indicate statistical significance. KEMPKF, internal knee extensor moment at peak knee flexion; KFAIC, knee flexion angle at initial contact; KFAPKF, knee flexion angle at peak knee flexion.
b
Effect sizes calculated when differences between limb means exceeded the minimal clinically important difference value.
