Wearable tech tracks movement in rare bone disorders

This study is for people aged 3 and older with achondroplasia or hypochondroplasia (types of skeletal dysplasia). It uses a wearable device called Syde® to measure limb movements over a year. The goal is to find out which movement measurements are reliable and useful for future research. No treatment is given—this is an observational study to better understand the condition.
