The goal of this observational study is to assess the interest of prefabricated carbon fiber ankle foot orthoses (AFO) in children and teenagers with central or peripheral neurological pathologies. The main question it aims to answer is: Does prefabricated carbon AFO improve gait and provide user satisfaction? In current practice, all patients with gait impairments were fitted with this orthosis and had a 3D gait analysis with and without AFO. Biomecanical and follow-up data collected in current practice are analysed in this study in order to answer the question.

Stride length
Biomechanical parameter: the distance between successive points of initial contact of the same foot (m)
Time frame: After 1 hour with the device
Walking speed
Biomechanical parameter: the walking speed is the time one takes to walk a specified distance on level surfaces over a short distance (m/s).
Time frame: After 1 hour with the device
Walking cadence
Biomechanical parameter: the walking rate is equal to the walking speed divided by the stride lenth (steps/min).
Time frame: After 1 hour with the device
Gait Profile Score
Biomechanical parameter: the Gait Profile Score (GPS) is a clinical index that can be used to measure the overall deviation of gait data relative to normative data (°).
Time frame: After 1 hour with the device
Gait Variable Score for the Hip
Biomechanical parameter: the Gait Variable Score describes the joint specific measures of gait variability for the Hip (°).
Time frame: After 1 hour with the device
Gait Variable Score for the Knee
Biomechanicl parameter: the Gait Variable Score describes the joint specific measures of gait variability for the Knee (°).
Time frame: After 1 hour with the device
Gait Variable Score for the Ankle
Biomechanical parameter: the Gait Variable Score describes the joint specific measures of gait variability for the Ankle (°).
Time frame: After 1 hour with the device
Walk ratio
Biomechanical parameter: the walk ration represents the relationship between the amplitude and frequency of rhythmic leg movement during walking (m/step/min).
Time frame: After 1 hour with the device
Antero-posterior Ground Force Reaction
Biomechanical parameter: the antero-posterior Ground Force Reaction is the antero-posterior force exerted by the ground on a body in contact with it (N).
Time frame: Afer 1 hour with the device
Time of Stance
Biomechanical parameter: the time of stance is the time one spend with the foot on the floor (s)
Time frame: After 1 hour with the device
Stance percentage
Biomechanical parameter: the stance percentage is the percentage of time one spend with the foot on the floor during the gait cycle (%)
Time frame: After 1 hour with the device
Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST)
Questionnaire: the QUEST measures the user satisfaction. It contains an evaluation part regarding the technology of the device on 8 items and one regarding services around the device on 4 items. It allows the patient to express himself on the criteria that are most important to him. An average satisfaction value can be calculated on a scale going from 1 to 5, with 1= "Not at all satisfied", 2="Not very satisfied", 3="more or less satisfied", 4="Quite satisfied" or 5="Very satisfied". The final QUEST score is the average obtained over all 12 items. Technology and services sub-scores can also be calculated. In this study, the french version ESAT (Evaluation des la Satisfaction envers une Aide Technique) is used. This questionnaire only concerns patients who purchase the orthosis, and was administered during a follow-up visit of the patient in the rehabilitation center.
Time frame: Between 3 to 18 months after the fitting with the device / Long-term follow-up visit
