Table 1 Isokinetic strength measurements

From: Functional deficits in chronic mechanical ankle instability

Isokinetic strength Non-affected ankle (mean ± SD) MAI ankle (mean ± SD) ANOVA (p, F)
Maximum torque (Nm)
 Plantarflexion 88.1 ± 28.2 69.8 ± 28.0 p< 0.0001,F= 10.80
 Dorsiflexion 28.2 ± 7.6 27.9 ± 8.1 p = 0.68, F = 0.92
 Supination 24.8 ± 8.7 20.9 ± 9.6 p< 0.001,F= 3.37
 Pronation 15.9 ± 5.9 13.7 ± 5.6 p< 0.001,F= 3.94
Peak torque angle (°)
 Plantarflexion − 5.7 ± 5.7 − 4.0 ± 6.7 p = 0.0603, F = 2.40
 Dorsiflexion 12.4 ± 6.3 10.5 ± 8.1 p = 0.054, F = 1.16
 Supination* − 15.4 ± 8.5 − 15.8 ± 7.8 p = 0.78, F = 0.71
 Pronation* 20.1 ± 7.7 14.0 ± 10.7 p< 0.0013,F= 5.41
  1. Nm Newtonmeter, MAI mechanical ankle instability, ROM range of motion
  2. *Negative value means that peak torque for supination is achieved with the foot in pronation and vice versa
