[Underfoot pressure distribution of female patients with obesity and plantar fasciitis].

Objective: Estimation of underfoot pressure distribution of female patients with obesity and bilateral plantar fasciitis.
Material: 45 women aged 58 (SD +/- 9.0) with obesity confirmed by BMI (BMI = 38.2, SD +/- 5.1) and hindfoot-related bilateral pain complaints typical for plantar fasciitis. The control group consisted of 50 women with no obesity and pathologies of motor apparatus found.
Methods: Clinical and radiological examination and postural pedobarography. The underfoot pressure was determined at defined foot regions according to modified Blomgren classification.
Results: When compared with the control group, patients with obesity had increased pressure within metatarsus, mainly in its lateral part and within anterior part of hindfoot (MT5, MM, LM, T zone). The maximal value of underfoot pressure was 1052 g/cm2 in patients with obesity and 784 g/cm2 in the control group. There were no statistically significant differences found between underfoot pressures and stronger and lesser pain complaints occurring in one patient.
Conclusions: 1) In obese women with bilateral plantar fasciitis increased underfoot pressure mainly in the lateral part of metatarsus and anterior part of hindfoot was revealed. 2) The above changes correlate with feet dysfunction confirmed during the interview and through the physical examination.
