Abstract:
Objective:To analyze the dynamic plantar pressure distribution of persons with chronic plantar fasciitis (PF).Methods:Twenty persons with unilateral, chronic PF were recruited as the PF group, while twenty-three healthy counterparts were recruited as the control group. A foot-pressure measurement system was used to collect data describing the plantar pressure for each subject with or without PF while walking. The pressure data included the load of peak plantar pressure (PP), the mean plantar pressure (MP), the total foot ground contact area (TCA), and the load percentage and the foot ground contact area beneath the medial heel (MH), the lateral heel (LH), the medial longitudinal arch (MLA), the lateral longitudinal arch (LLA), the first metatarsal head (M1), the second to third metatarsal heads (M2-3), the fourth to fifth metatarsal heads (M4-5), the hallux (T1), and toes two to five (T2-5).Results:In the PF group, significant differences were observed during walking between the affected and unaffected feet in terms of PP [(2.41±0.44)kg/cm 2 versus (3.02±0.63)kg/cm 2]. Both were significantly greater than among the control group. Asymmetry in the load distribution was identified beneath the MH, M2-3, M1, MLA, M4-5 and T2-5 among the chronic PF group. There were also significant differences between the affected foot of the chronic PF group and the non-dominant foot of the control group with regard to the load percentage beneath the LH, M4-5, T2-5, M2-3 and T1. The load percentage under the LH was significantly higher under the unaffected foot of the PF group than under the dominant foot of the control group. In terms of ground contact area, the T2-5 area of the affected foot of the PF group was significantly smaller than that of the unaffected foot, as well as compared to the non-dominant foot of the control group. The TCA of both feet among the PF group was significantly smaller than under the corresponding feet of the control group. Conclusions:Patients with chronic plantar fasciitis apply plantar pressure asymmetrically during walking. They tend to shift their weight laterally onto the asymptomatic foot. During walking, those with PF apply higher plantar pressure over a smaller ground contact area.
