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.
Unzip the entire folder and
run calcDistance.m and it will load the IMU data from the Xsens_rollator folder and then create fig files in the OutputFigs folder. There are also variables in this zip file that contain output data (meanPushDist and totalPushes) which show
average push distance and total number of pushes for each trial.
