Description
Children with spastic hemiplegia, stiffness and weakness down one side, walk with a gait whose faults hide in the interplay between joints. Zijun Lu and co-authors dissect that interplay in a 2025 study. Twenty-one affected children and twenty-one typically developing peers walked through a motion-capture lab while force data recorded every step.
The team split each joint's motion into the torques that cause it: muscle torque, the push of the ground, and the interactive torque passed from neighboring segments. Affected children bent knee and ankle less. During double support their ground-torque coordination sagged, while in single support their hips and knees leaned harder on muscle and interactive torques to compensate. The authors offer the imbalance map as a guide for therapy aimed at the right joint at the right moment.
