Demonstrates reduced knee contact force from ankle exoskeleton assistance in individuals with cerebral palsy, suggesting improved mobility outcomes.

The study aims to quantify how ankle exoskeleton assistance affects knee contact force during walking in individuals with cerebral palsy.
Measured knee contact force in children and young adults with cerebral palsy while walking with shoes and ankle exoskeletons.
Utilized an electromyography-informed modeling approach for estimating muscle forces.
Mapped muscle activations from eight lower limb muscles to assess their impact on knee loading.
Ankle exoskeleton assistance reduced peak late-stance knee contact force by 9.3% and average stance-phase knee contact force by 7.2%.
Stance-phase quadriceps muscle force decreased by 9.1% with exoskeleton use.
Changes in knee extensor muscle forces correlated with reduced knee loading during walking.
