Résumé : |
Objective To identify clinical and biomechanical parameters that influence swing-phase knee flexion and contribute to stiff-knee gait in individuals with spastic cerebral palsy (CP) and flexed-knee gait. Design Retrospective analysis of clinical data and gait kinematics collected from 2010 to 2013. Setting Motion and gait analysis laboratory at a children's hospital. Participants Individuals with spastic CP (N=34; 20 boys, 14 girls; mean age + SD, 10.1+4.1y [range, 520y]; Gross Motor Function Classification System IIII) who walked with flexed-knee gait ≥20° at initial contact and had no prior surgery were included; the more-involved limb was analyzed. Intervention Not applicable. Main Outcome Measures The magnitude and timing of peak knee flexion (PKF) during swing were analyzed with respect to clinical data, including passive range of motion and Selective Control Assessment of the Lower Extremity, and biomechanical data, including joint kinematics and hamstring, rectus femoris, and gastrocnemius muscle-tendon length during gait. Results Data from participants demonstrated that achieving a higher magnitude of PKF during swing correlated with a higher maximum knee flexion velocity in swing (ρ=.582, P Conclusions Results indicate that the magnitude and timing of PKF during swing were independent, and their biomechanical correlates differed, suggesting important treatment implications for both stiff-knee and flexed-knee gait. |
