A standard clinical gait analysis consists of observing walking with video (2D) or advanced equipment (VICON 3D). This 3D method provides detailed information about the gait pattern, but is time-consuming in implementation and data analysis. There are commercial 3D systems on the market that are used in healthy individuals and in sports. These so-called Inertial Measurement Units (IMUs) may also be suitable for use in the clinic. In this research protocol, the aim is to test the usability of commercial sensors and technically compare them with standard clinical 3D gait analysis in adult patients with a neurological disorder.
Measurements will include subjects that perform routine clinical 3D gait analysis because of a clinical question related to stiff knee gait or surgical intervention of the foot. During routine clinical gait analysis, Vicon markers and EMG-measurements of specified muscles is included. IMU-sensors will be included to this routine measurements to measure accelorometer, gyroscope and magnetometer data of both feet, both upper and lower legs, the sternum and the sacrum.
