Pain score of the more affected leg.
The black dots represent the pain score of each participant in each group. The histogram with an error bar represents the mean and standard deviation of the pain score in the PNF and control groups at weeks 0 and 9. * denotes significant difference between weeks 0 and 9 in the PNF group. # denotes significant differences between PNF and control groups at week 9.
Fig 4.
The KAM of the more affected leg.
The black line presents exemplary KAM during the support phase from the leading leg touching down on the force platform until it takes off from it. The histogram with an error bar represents the mean and standard deviation of the peak values in the PNF and control groups at weeks 0 and 9. * denotes significant differences between weeks 0 and 9 in the PNF group. # denotes significant differences between PNF and control groups at week 9.
