Rollator movement motion sensing data - gold standard

This is an initial study to characterise rollator
movement. An inertial measurement unit (IMU) was used to measure the motion of
the rollator and analytical approaches were developed to extract features
characterising the rollator movement, properties of the surface, and push
events. The analytics were tested in two situations, firstly a healthy
participant used a rollator in a laboratory using a motion capture system to
obtain ground truth. Secondly the IMU was used to measure the movement of a
rollator being used by a user with multiple sclerosis (MS) on a flat surface,
cross-slope, up and down slopes, and up and down a step <br>The dataset of motion sensing movement is comprised of seven straight-lighting walking trials (between 4-5 m) performed by a healthy participant using a rollator in a gait lab. The raw data were in csv format recorded by VICON system and subsequently analysed in Microsoft Excel 2013 to calculate the distance travelled by a rollator.
