    Changes in the Plantar Pressure Distribution During Gait Throughout Gestation
    (2011) RIBEIRO, Ana Paula; TROMBINI-SOUZA, Francis; SACCO, Isabel de Camargo Neves; RUANO, Rodrigo; ZUGAIB, Marcelo; JOAO, Silvia Maria Amado
    Background: The intention of this investigation was to longitudinally describe and compare the plantar pressure distribution in orthostatic posture and gait throughout pregnancy. Methods: A prospective longitudinal observational study was conducted with six pregnant women (mean +/- SD age, 32 +/- 3 years) with a mean +/- SD weight gain of 10.0 +/- 1.4 kg. Peak pressure, contact time, contact area, and maximum force in five plantar areas were evaluated using capacitive insoles during gait and orthostatic posture. For 1 year, the plantar pressures of pregnant women were evaluated the last month of each trimester. Comparisons among plantar areas and trimesters were made by analysis of variance. Results: For orthostatic posture, no differences in contact time, contact area, peak pressure, and maximum force throughout the trimesters were found. During gait, peak pressure and maximum force of the medial rearfoot were reduced from the first to third and second to third trimesters. Maximum force increased at the medial forefoot from the first to second trimester. Contact area increased at the lateral rearfoot from the second to third trimester and at the midfoot from the first to third trimester. Contact time increased at the midfoot and medial and lateral forefoot from the first to third trimester. Conclusions: Pregnant women do not alter plantar pressure during orthostatic posture, but, during gait, the plantar loads were redistributed from the rearfoot (decrease) to the midfoot and forefoot (increase) throughout pregnancy. These adjustments help maintain the dynamic stability of the pregnant woman during locomotion. (J Am Podiatr Med Assoc 101(5): 415-423, 2011)

    Rearfoot alignment and medial longitudinal arch configurations of runners with symptoms and histories of plantar fasciitis
    (2011) RIBEIRO, Ana Paula; TROMBINI-SOUZA, Francis; TESSUTTI, Vitor; LIMA, Fernanda Rodrigues; SACCO, Isabel de Camargo Neves; JOAO, Silvia Maria Amado
    OBJECTIVE : To evaluate and compare rearfoot alignment and medial longitudinal arch index during static postures in runners, with and without symptoms and histories of plantar fasciitis (PF). INTRODUCTION: PF is the third most common injury in runners but, so far, its etiology remains unclear. In the literature, rearfoot misalignment and conformations of the longitudinal plantar arch have been described as risk factors for the development of PF. However, in most of the investigated literature, the results are still controversial, mainly regarding athletic individuals and the effects of pain associated with these injuries. METHODS: Forty-five runners with plantar fasciitis (30 symptomatic and 15 with previous histories of injuries) and 60 controls were evaluated. Pain was assessed by a visual analogue scale. The assessment of rearfoot alignment and the calculations of the arch index were performed by digital photographic images. RESULTS: There were observed similarities between the three groups regarding the misalignments of the rearfoot valgus. The medial longitudinal arches were more elevated in the group with symptoms and histories of PF, compared to the control runners. CONCLUSIONS: Runners with symptoms or histories of PF did not differ in rearfoot valgus misalignments, but showed increases in the longitudinal plantar arch during bipedal static stance, regardless of the presence of pain symptoms.
