Functional deficits in chronic mechanical ankle instability

Table 1 Isokinetic strength measurements

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

Nm Newtonmeter, MAI mechanical ankle instability, ROM range of motion
*Negative value means that peak torque for supination is achieved with the foot in pronation and vice versa
