Preintervention to postintervention comparison of involved limb and uninvolved limb. A, Knee-extension maximal voluntary isometric contraction torque. B, Quadriceps central activation ratio. C, Limb symmetry index for both measures among individuals with a history of anterior cruciate ligament reconstruction. ^a Indicates difference between preintervention and postintervention measures in the involved limb (P ≤ .05). ^b Indicates difference between preintervention and postintervention measures in the uninvolved limb (P ≤ .05).
