To measure spasticity, a KinCom dynamometer dorsiflexed the passive ankle at five different speeds and recorded the resistive plantarflexion torques. Work values for the torque-angle data were calculated at each speed. Using this data, linear regression was used to measure spasticity. To measure strength, the dynamometer rotated the ankle from maximum dorsiflexion to maximum plantarflexion at a speed of 10 degrees/s while the child performed a maximum plantarflexion concentric contraction. The movement was reversed to record maximum dorsiflexion. Maximum torques and work by the plantarflexors and dorsiflexors were calculated. The group with CP had significantly more spasticity in the plantarflexors and significantly less strength in the plantarflexors and dorsiflexors than the group without CP. Results provide objective information quantifying ankle spasticity and strength in children with CP.
