A collaborative research between Paediatric Neurology and Neurorehabilitation Unit of the Lausanne University Hospital (CHUV) and the Laboratory of Movement Analysis an Measurement of the Swiss Federal Institute of Technology in Lausanne (EPFL) measured upper limb function in children with hemiparesis with 3D inertial sensors.
Upper limb assessments in children with hemiparesis rely on clinical measurements, which despite standardization are prone to error. The team instrumented 30 participants in a mirror therapy clinical trial at baseline, post–treatment, and follow–up clinical assessments, with wireless inertial sensors (Physilog®) positioned on the arms and trunk to monitor motion during reaching tasks.
They demonstrated that inertial sensor measurements reliably identify paresis and correlate with clinical measurements; they can therefore provide a complementary dimension of assessment in clinical practice and during clinical trials aimed at improving upper limb function.
