KINEMATIC COMPARISON OF ORTHOPEDIC SHOES AND ANKLE-FOOT ORTHOSES IN CHILDREN WITH CEREBRAL PALSY

Introduction 
Cerebral palsy (CP) patients may have additional complications such as deformities of lower limbs which significantly change the gait pattern. Various treatments have been used to correct the walking gait and among them are orthotic devices. According to the data based on literature research the ankle-foot orthoses (AFOs) are the most widely used in clinical practice for CP patients. However, orthopedic shoes are more widely used in Russia and there is a lack of gait comparison research has been done up to date. Aim. Kinematic data comparison of walking gait between orthopedic shoes and AFOs in children with CP. Materials and methods. Eighteen CP children with GMFCS 2 and GMFCS 3 were recruited for this research. Three test comparisons were conducted for barefoot, orthopedic shoes, and AFOs walking for each children being tested. Twelve Miqus M5 Qualisys cameras were used for kinematic data collection with 100 Hz frequency. Visual3D (C-Motion), Clinical Gait PAF (Qualisys), Statistica 10, and Excel were used for data analysis. Results. The results demonstrated that wearing AFOs versus barefoot improved spatial-temporal parameters as well as ankle and knee joint kinematics without significant changes in hip joint angles for both GMFCS 2 and GMFCS 3 levels. As a result, the Gait Profile Score (GPS) showed significant improvement in AFOs as well. The use of orthopedic footwear in patients with gross motor function levels GMFCS 2 and GMFCS 3 led to improvement of ankle and knee joints kinematics when compared to barefoot walking. However, the group with GMFCS 2 demonstrated less improvement of the ankle and knee joint angles in orthopedic shoes but the GPS showed significantly better overall values when compared to GMFCS 3 group. Therefore, this study showed that orthopedic footwear and AFOs almost equally corrected the walking gait in GMFCS 2 group but AFOs were significantly better for GMFCS 3 group.
