Prospective Longitudinal Multicentric Study to Measure Limb Movement in Patients With FGFR3-related Skeletal Dysplasia (SKY-MOT3)
Prospective Longitudinal Multicentric Study to Measure Limb Movement in Patients With FGFR3-related Skeletal Dysplasia Using Syde®
The study aims to identify which Syde®-derived digital outcomes are reliable in FGFR3-related Skeletal Dysplasia. This requires to set-up a natural history study to measure limb movements in patients with ACH or HCH.

Popolazione di studio
France: Participants will be recruited from the patient registry of the Centre de Référence des Maladies Osseuses Constitutionnelles located at Necker Hospital / IMAGINE Institute. The APPT association (Association des Personnes de Petite Taille) will also help with the recruitment through flyers distribution. All visits will take place at Necker Hospital.
Belgium: Participants will be recruited from the Maladies Rares Génétiques Ostéo-articulaires (MaRGOs) patient registry located at Centre Hospitalier Universitaire (CHU) de Liège, with additional recruitment through Centre Hospitalier Régional (CHR) de Liège and support from the Solidarité Wallonne des Personnes de Petite Taille association through flyer distribution. All visits will take place at CHU de Liège and CHR de Liège.
United Kingdom: Participants will be recruited from the Site Research Waiting List

System Usability Score (SUS) at 6 months. The System Usability Scale is a 10-item questionnaire . It is a simple tool to measure the usability of an interactive system and it is widely used. For each item, the user is asked to express their level of agreement or disagreement from 1 (strongly disagree) and 5 (strongly agree). |
