Does footprint and foot progression matter for ankle power generation in spastic hemiplegic cerebral palsy?
Abstract
Objectives: We investigated how foot pressure pattern and foot progression relate to power generation from the ankle joint in children with spastic hemiplegic cerebral palsy (CP).
Methods: The study included 35 children (13 girls, 22 boys; mean age of 8.8 years; range 4 to 19.8) with CP, all having independent ambulation. The children underwent three-dimensional gait analysis and a set of pedobarographic data were obtained. The pedobarographs were analyzed by dividing the foot into five segments.
Results: The mean power generation from the ankle was 7.6 watts/kg on the hemiplegic side, and 15.9 watts/kg on the uninvolved side (p=0.000). Based on the pedobarographic data, hemiplegic feet exhibited significantly less heel pressure/impulse (8.0 vs. 24.7; p=0.000), time to heel rise (32.1% of stance phase vs. 61.9%; p=0.000), and decreased pressure of the medial forefoot segment (40.8 vs. 52.2; p=0.009). The children were divided into two groups depending on the ankle power generated on the hemiplegic side (
