Fig. 15

The plots of the data trend of force measurement and their SPM1D results when comparing NW_SW with other trials. The blue line and orange line represent the data of NW_SW and the respective walking trials, respectively. The dotted line represents the end of the stance phase and the beginning of the swing phase while the red dotted line is the fall triggering instance. In each subfigure, the first row shows the mean of the data with its standard deviation as shaded region. The second row shows the F-values compared against the threshold. Statistical results greater than the threshold indicate a statistically significant difference between the two groups. Only one side of the NW_C gait cycle is shown due to symmetry. As the left foot did not always take a step after the slip and knee buckling, the left foot gait cycles are omitted
