3. Fig 2
A scheme of the areas for which partial foot pressure as a percentage of body weight (%PFP) was measured. The footprinted area during walking was divided into the heel, central, metatarsal, hallux, and lateral toes parts according to the average foot length of healthy individuals. The most posterior 34.5% of the footprinted area was defined as the heel, the next 24% as the central part, the next 26.5% as the metatarsal part, and the most anterior 15% as the toes part. The medial 22% of the toes part was defined as the hallux part and the lateral 78% as the lateral toes part.

4. Fig 3
A scheme showing %Long (left) and %Trans (right). %Long was defined as the anteroposterior length of the COP path (b) as a percentage of foot length (a). %Trans was defined as the transverse width of the COP path (d) as a percentage of foot width (c).

5. Fig 4
Foot pressure patterns of typical subjects of the elderly group (left) and of the OA group (right). The lines show the COP paths. Red indicates a high level of foot pressure and blue a low level of foot pressure. The short and straight appearance, and the lateralization of the end of the COP path are characteristic features. Note the low pressure on both the hallux and the heel in the OA group.

6. Fig 5
The %Long values of the OA, young, and elderly groups. The %Long was significantly lower in the OA group than in either the young group or the elderly group. #P<.001.

7. Fig 6
The %Long values of the 3 subgroups of the OA group. Within the OA group, the %Long was significantly lower in the 10° group than in either the 5° group or the no-limitation group, and was also significantly lower in the 5° group than in the no-limitation group. #P<.001.
