Supporting files 1 to 7 contain all the datasets used in this paper. The supporting files are excel files (.xlsx) for data from inertial sensors on the shank and the backfor YH,OH and PwP participants respectively. Each excel file contains a separate spreadsheet for individual participant with six columns corresponding to X, Y and Z axis data from accelerometer and X, Y and Z axis data from gyroscope respectively. Each column is clearly labelled along with the units of measurement. Additionally, the reference kinematics obtained from Codamotion data are included in a separate file. The data files are named as follows:
