Ambulatory children with cerebral palsy (CP) demonstrate altered lower limb biomechanical alignment in walking (e.g. excessive hip/knee flexion or equinus during stance) and experience walking activity limitations that negatively influence their ability to participate in day to day life. Ankle Foot Orthoses (AFO) are a fundamental rehabilitation strategy to facilitate walking in children with CP; yet, a review suggests that efficacy of the "traditional" solid AFO (TSAFO) in this population remains equivocal. A novel decision tree to guide orthotic prescription proposes a patient-specific method for adjusting AFO alignment and integrating footwear modifications (Ankle Foot Orthoses-Footwear Combinations, AFO-FC). This approach is based on visualizing the sagittal plane orientation of the ground reaction force vector with respect to lower limb segments during gait. The AFO-FC represents a paradigm shift in orthotic management as it accommodates ankle equinus contractures in a rigid AFO, reorients the tibial segment with a heel wedge under the AFO, and applies different heel, midsole and forefoot shoe modifications to restore lost ankle-foot rockers. The primary goal of AFO-FCs are to improve stability by facilitating more normal segment kinematics in single limb stance, decreasing hip/knee flexion. Despite their promise, evidence of an immediate positive effect on midstance alignment is limited, with no evidence of clinical effectiveness.
This proposal assesses the feasibility of using a randomized waitlist study to acquire pilot data on a targeted clinical cohort of children with CP evaluating the effectiveness of AFO-FCs as compared to TSAFO during daily life. Individual joint and combined kinematics and kinetics will be examined for potential mechanisms of action as well as daily walking performance, balance and satisfaction with the AFO-FC in 30 ambulatory children with CP, ages 4-9 years, with bilateral crouch or equinus gait pattern, comparing gait in TSAFO to the AFO-FCs.
The goal of this proposal is to assess the feasibility of using a randomized waitlist study to acquire pilot data on a targeted clinical cohort of children with CP evaluating the effectiveness of AFO-FCs as compared to TSAFO during daily life. Individual joint and combined kinematics and kinetics will be examined for potential mechanisms of action as well as daily walking performance, balance and satisfaction with the AFO-FC in 30 ambulatory children with spastic diplegia CP, ages 4-9 years, with bilateral crouch or equinus gait pattern, comparing gait in TSAFO to the AFO-FCs.
Aim 1: Examine the effect of AFO-FC on individual joint kinematics, overall gait deviations and walking speed as compared to the TSAFO in children with CP. Multiple gait deviations (e.g. crouch or equinus) in CP result in slow, inefficient walking [14]. We hypothesize that the individualized ankle angle, leg segment alignment, and footwear profiles of the AFO-FCs will optimize lower limb joint kinematics, decrease overall gait deviations facilitating longer step lengths (improved stance stability), with resultant increased gait speed as compared to TSAFO. Instrumented gait analysis will assess gait speed and calculate changes in joint specific kinematics with the Gait Profile Score (GPS) and overall combined gait kinematics with the GDI.
Aim 2: Examine the effect of AFO-FC on daily walking activity, balance, mobility, and satisfaction as compared to the TSAFO in children with CP. We hypothesize that the AFO-FC will positively affect community walking activity levels, balance, physical activity and satisfaction as compared to the TSAFO. Walking activity will be captured by the StepWatch ® accelerometer; balance by the Pediatric Balance Scale; physical activity by the Patient Reported Outcomes Measurement System (PROMIS®) Pediatric Physical Activity and the Gait Outcomes Assessment List (GOAL); and satisfaction with device by the Orthotic and Prosthetic Users' Survey (OPUS).

|---|---|---|
| Change in Baseline Gait Profile Score (GPS) at 3 Months-individual Lower Extremity Joint Kinematics | The Gait Profile Score (GPS) represents the pattern of deviation as a single number and is derived from the same individual joint/limb gait kinematics as Gait Deviation Index (GDI) The GPS minimum value is 0 and maximum value is 20. A higher score is a worse outcome. An minimally clinically important difference is published to be 1.6 for children with CP. | 3 months post wearing assigned orthotic intervention |
| Change in Right Baseline Gait Deviation Index (GDI) at 3 Months | Gait Deviation Index (GDI) as a value representing overall gait deviation from a normal kinematic profile (0 to 120 scale) captures cumulative changes occurring at multiple joints and segments by side left/right. GDI has been shown to have concurrent validity with gross motor function and functional walking levels in children with CP. A score > 100 is considered in the normal range. A higher score is a better outcome. | 3 months post wearing assigned orthotic intervention |
| Change in Baseline Walking Speed in Meters/Second (m/s) at 3 Months. | Gait speed will be captured during the three dimensional gait analysis testing. Gait speed is measured in meters per second (m/sec) with range from 0 to ~ 3.0 m/sec for walking in children. A higher number of m/sec is considered a better outcome with minimally clinically important difference (MCID) of .10 m/s for persons with CP. | 3 months post wearing assigned orthotic intervention |
| Change in Baseline Community Walking Activity Level at 3 Months in Strides/Day. | Community walking activity will be captured by the ankle worn StepWatch ® accelerometer capturing change in average strides/day. The StepWatch ® is a two dimension accelerometer validated to capture when the foot leaves the ground for a metric of stride counts within the context of daily life. Average strides/day can range from 0 to unlimited strides/day. A higher number of strides/day is considered a better outcome. |
