What this Trial Is About

Children with spastic cerebral palsy (CP) often have altered walking patterns due to their condition. This research aims to study how ankle-foot orthoses (AFOs), devices commonly prescribed to improve walking, affect muscle activity in the lower legs of these children during walking. The study focuses on understanding the timing and strength of muscle activity as well as the coordination between muscles. During the study, children will undergo a clinical exam followed by a detailed walking analysis using 3D gait analysis both on the ground and on a treadmill. These tests will measure muscle activity using EMG, as well as movements and forces involved in walking. The study includes ambulatory children aged 6 to 17 years with spastic CP who have been prescribed AFOs as part of their usual care. Participants will be observed during a single measurement session lasting about 150 minutes. Researchers will collect data on muscle activity patterns, including muscle activation timing and co-activation of muscles in the legs. This information will help understand how AFOs influence muscle use in walking. The study will also monitor walking mechanics and muscle function during the tests to evaluate the effects of AFOs comprehensively.

Your Study Journey

Screening

Duration - 2 to 4 weeks

Participants are screened for eligibility to participate in the trial.

1 visit (in-person)

Diagnostic Evaluation

Duration - 1 day

Participants undergo a standard clinical examination and clinical overground three-dimensional gait analysis (3DGA) as part of routine clinical follow-up, extended with additional 3DGA on the treadmill to collect kinematic, kinetic, and EMG data.

1 visit (in-person)

Long-term Monitoring

Duration - Ongoing as part of standard care

Participants who undergo routine care with prescribed ankle-foot orthoses are observed to assess muscle activity during walking.

No additional visits beyond routine care
