Effects of a Postoperative Strength-Training Program on the Walking Ability of Children With Cerebral Palsy: A Randomized Controlled Trial

Flow diagram of the randomization procedure.

(A—D) Spatiotemporal parameters for the control (CG) and strength-training (SG) groups, before (E0), 1 year after (E1), and 2 years after (E2) the surgery. The normative values with SD are represented by the continuous horizontal line and the grey zone (n=29). NOTE. Values are mean ± SD. *Significant differences between the measurements for the merged group (CG+SG) that were examined at E0, E1, and E2.

Normalcy index and kinematic parameters for the control and strength-training groups, prior to, 1 year after, and 2 years after surgery. (A) Normalcy index, (B) minimum knee flexion during terminal swing, (C) maximum hip extension, and (D) maximum plantarflexion during stance to swing transition. The normative values with SD are represented by the continuous horizontal line and the grey zone (n=29). NOTE. Values are mean ± SD. *Significant differences between the measurements for the merged group (CG+SG) that were examined at E0, E1, and E2.

Kinetic parameters for the control and strength-training groups prior to, 1 year after, and 2 years after surgery. (A) Maximum hip power absorption, (B) maximum plantarflexor moment, (C) maximum knee power absorption during loading responses, and (D) maximum ankle power generation. The normative values with SD are represented by the continuous horizontal line and the grey zone (n=29). NOTE. Values are mean ± SD. *Significant differences between the measurements for the merged group (CG+SG) that were examined at E0, E1, and E2.
