Stroke
Conditions
Brief summary
The objective is to validate the algorithms for movement analysis that were developed previously in healthy participants, in a small study with stroke patients. Stroke subjects will be measured while performing tasks like walking, sitting and standing while wearing light-weight inertial measurements units (IMUs) incorporating 3D accelerometers, 3D gyroscopes and surface electromyography. During the measurements subjects will be recorded on video that serves as ground truth when validating the implemented algorithms for movement analysis. A face blurring program will be used for all video footage.
Detailed description
Subjects will perform the following tasks: 30 sec stationary sitting/standing/lying; 10m walk test; L-test; 8-figure walking test; daily life task; stepping over small obstacles; walk in the corridor. During the measurments IMU will be placed at: sternum; sacrum; bilateral wrists; bilateral shanks; bilateral upper legs; both feet. Surface EMG of bilateral rectus femoris; vastus lateralis; medial gastrocnemius and soleus will be measured.
