Foot progression angle (FPA) and duration of foot medial column loading during
walking were studied in individuals with diabetes mellitus (DM), peripheral
neuropathy (PN), and a forefoot ulcer (DMPN), and in age-matched control
subjects. FPA was calculated from EMED-ST P-2 pressure maps as the angle formed
between the longitudinal axis of the foot and the forward line of progression
during walking. The medial loading duration was calculated as the amount of time
the center of pressure line spent in the medial side of the foot pressure map.
FPA was increased in the DMPN group, on the involved and uninvolved sides [15(9)
degrees and 13(4) degrees respectively] compared the control group [9(4) degrees
]. FPA and medial loading duration were significantly correlated in the DMPN
group on the involved and uninvolved sides (r>0.54, p<0.036), but were not
significantly correlated in the control group (r<|0.07|, p>0.82). This study
provides evidence that FPA is an important biomechanical contributor to the
pattern of foot loading in individuals with DM, PN, and a forefoot ulcer.
