10.15 Gait Ratios analysis
The gait ratios analysis is available in the Clinical, Scientific package(s).
The gait ratios analysis (Figure 52 ) gives a comparison for the selected left and/or right
foot and the average for all measured left and/or right feet for specific calculations.
Figure 52:
The gait ratios analysis screen.
The gait ratios analysis provides specific calculations about different aspects of the roll-
off. The gait ratios are calculated by analyzing the progression of pressure under each
of the zones of the feet and by comparing the medial part of the foot with its lateral part.
Each graph depicts a gait ratio analysis for the selected feet (left and/or right) and the
average for all measured left and/or right feet. The low risk area indicates the area with
a low risk of lower limb injuries. More information can be found in the appendix of this
manual (see
19 ).
Each gait ratio analysis focuses on a different and specific property of the roll-off:
Heel rotation
Heel rotation is defined as the mediolateral pressure distribution at the level of the
rearfoot during stance phase. The mediolateral pressure distribution at the level of the
rearfoot is calculated by comparing the pressure under the medial heel (MH) with the
pressure under the lateral heel (LH).
An increased pressure underneath the medial heel suggest an eversion of the rearfoot,
an increased pressure underneath the lateral heel suggest an inversion of the rearfoot.
Hallux stiffness
Hallux stiffness is defined as the pressure distribution between the first toe (T1) and the
first metatarsal head (M1) during stance phase. Hallux stiffness is calculated by
comparing the pressure underneath the first toe with the pressure underneath the first
metatarsal head.
