Conditions
Brief summary
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Stride length | After 1 hour with the device | Biomechanical parameter: the distance between successive points of initial contact of the same foot (m) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Walking cadence | After 1 hour with the device | Biomechanical parameter: the walking rate is equal to the walking speed divided by the stride lenth (steps/min). |
| Gait Profile Score | After 1 hour with the device | 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 (°). |
| Gait Variable Score for the Hip | After 1 hour with the device | Biomechanical parameter: the Gait Variable Score describes the joint specific measures of gait variability for the Hip (°). |
| Gait Variable Score for the Knee | After 1 hour with the device | Biomechanicl parameter: the Gait Variable Score describes the joint specific measures of gait variability for the Knee (°). |
| Gait Variable Score for the Ankle | After 1 hour with the device | Biomechanical parameter: the Gait Variable Score describes the joint specific measures of gait variability for the Ankle (°). |
| Walking speed | After 1 hour with the device | Biomechanical parameter: the walking speed is the time one takes to walk a specified distance on level surfaces over a short distance (m/s). |
| Antero-posterior Ground Force Reaction | Afer 1 hour with the device | 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 of Stance | After 1 hour with the device | Biomechanical parameter: the time of stance is the time one spend with the foot on the floor (s) |
| Stance percentage | After 1 hour with the device | Biomechanical parameter: the stance percentage is the percentage of time one spend with the foot on the floor during the gait cycle (%) |
| Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST) | Between 3 to 18 months after the fitting with the device / Long-term follow-up visit | 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. |
| Walk ratio | After 1 hour with the device | Biomechanical parameter: the walk ration represents the relationship between the amplitude and frequency of rhythmic leg movement during walking (m/step/min). |
