Category: Midfoot/Forefoot Introduction/Purpose: Hallux valgus (HV) is one of the most common forefoot problems. HV is defined as a hallux valgus angle of more than twenty degrees. HV can lead to alterations of the plantar pressure pattern and clinical gait. This study examined the relationship between gait alterations and HV deformities. Methods: We examined 500 residents (161 men and 339 women; >50 years of age) of Miyagawa village in Mie, Japan in 2009, 2011 and 2013. They performed a 6-meter walk test at normal and maximum speed. We examined gait speed, the number of steps, and footprint between patients with normal (HV angle <20; n=350) and HV (HV angle >20; n=150), and between normal-to-mild (HV angle <30; n=436) and moderate-to-severe (HV angle >30; n=64). Their plantar pressure patterns were measured using a gait analyzer (Walk Way MW 1000; Anima, Tokyo, Japan, Figure.1). Statistical analyses were performed using the chi-square test according to sex and use of the hallux ball; the t-test according to age, height, and weight; and logistic regression analysis adjusted for age, sex, and height according to gait speed and the number of steps. P value less than 0.05 was considered significant. Results: With regard to the plantar pressure pattern, the percentage of subjects in the HV group who left a footprint of the hallux ball was significantly lower than that in the normal group. The percentage of subjects in the moderate-to-severe group who left a footprint of the hallux ball was even lower. Analysis of the footprint revealed that the HV group used the hallux ball significantly less during toe-off than the normal group. At both normal and maximum speed, the number of steps and gait speed did not differ significantly between the normal and HV groups. However, when we compared normal-to-mild and moderate-to-severe groups, the number of steps in the moderate-to-severe group was significantly greater than in the normal-to-mild group at maximum walking speed. Conclusion: Analysis of the footprint revealed that the percentage of subjects in the HV group who was able to use the hallux ball during toe-off was significantly less than that in the normal group. The percentage of subjects in the moderate-to-severe group who could use the hallux ball in toe-off was even lower. HV can cause footprint alterations. Moderate-to-severe HV can cause not only footprint alterations but also gait alterations, especially when walking at maximum speed.

Background: Previous studies that compared foot pressures in boys and girls found that girls had greater peak pressures under the hallux than did boys. Only one of these studies considered plantar pressure measurements in children. The purpose of the study was to investigate the effect of gender on foot pressure measurements in children. Methods: This is a comparative study using the F-Scan pressure platform (F-Mat; Texscan® Boston, MA) on a sample of children attending a podiatric clinic. Pressure measurements and temporal parameters were measured in 61 children between the ages of 5 and 16 years. Associations between joint hypermobility and hallux valgus angle also were investigated. Results: Girls were found to have significantly greater peak pressure under the hallux, faster timing of heel contact to first metatarsal head loading, and a more medially placed center of pressure trajectory. No associations were found between these significant variables and hypermobility scores or hallux valgus angle. Conclusion: The results indicate that there are differences in pressure measurements between boys and girls, but the reasons for these remain unclear. Differences in pressure measurements in the feet of boys and girls may be useful in establishing the cause of foot pathologies for which a prevalence has been shown in boys or girls, such as hallux valgus deformity, which is known to be more frequent in females of all ages.

Aim: Insoles have been widely accepted as a front-line defense to cushion the foot, decrease foot Pressure, and reduce tissue destruction associated with repetitive high pressures in the insensate foot. In recent years, plantar pressure has widely been accepted as a vital biomechanical parameter to evaluate human walking. The distribution and magnitude of plantar pressure can provide useful information to diagnose various foot disorders. Plantar pressure measurements during standing, walking or other activities can demonstrate the Pathomechanics of the abnormal foot and yield objective measures to track disease progression1. Areas of increased plantar pressure have been clearly linked to foot pain and discomfort. Increased pressure is also responsible for skin breakdown in the denervated foot such as in Hansen's disease and diabetic neuropathy. Planter pressure was studied with the use of both insoles Silicone gel and MCR (Micro cellular Rubber). Design: A repeated measure design was followed. Purpose: The aim of the study was to check the efficiency of both these commonly prescribed insoles (MCR and silicone gel insole) in terms of plantar pressure redistribution and center of pressure pattern with MCR insole and silicone gel insole. The data was managed on an excel spreadsheet and was analyzed using the SPSS software PASW (version 17.0). Descriptive statistics (Mean and standard deviation) were computed for each study variable. The outcome variables used for analysis were static planter pressure, dynamic planter pressure and center of pressure. The planter pressure measured for eight areas of the foot, i.e the hallux, 2-5 toe, 1st meta-tarsal, 2-4 meta-tarsal, 5th meta-tarsal, mid-foot, medial heel pressure and lateral heel pressure. A total of 30 subjects were recruited for the study. Out of 30 subjects, two were female and 28 were female. A kruskal-wallis test was used to compare the difference in planter pressure (static and dynamic) and center of pressure. The mean age of male subject was 65.53±5.02 years and female was 61.00±1.41 years and for entire population, the mean age was 65.23 ± 4.99 years. The mean of BMI for male subject was 23.95±2.34 and for female were 22.43±1.50 and for entire population was 22.40 ± 1.52. On the basis of preceding data, we conclude that both the insole MCR and silicone gel insole are effective in reducing planter pressure and realigning the center of pressure pattern. In some major pressure sensitive area of foot (Halux, 1st Metatarsal head etc.) silicone gel insole reducing more pressure than MCR insole. But MCR is a good alternative insole material in reducing the plantar pressure and maintaining the COP pattern.

Data Processing Protocol

The paper proposes a protocol used for data processing, designed to handling the foot pressure data recorded in human walking. This protocol represents a stage of a global protocol that deals with identification of some biomechanical parameters used in diagnosis and prediction. In order to validate the functionality of the data processing protocol, a lot of 10 patients suffering of Hallux Valgus deformity were recorded both before and after the surgery. The patients were divided into three age groups: 20-30, 40-50, 51-60. The measurements consist in recording of plantar pressure data in both dynamic (gait) and static way. This is an additional investigation to the clinical usual examinations in hallux valgus patients. The recorded data were averaged per each subject and then per whole lot. Based on determining the ground reaction force (GRF) variation in time and observing the foot pressures on static measurements, we can conclude that the static approach of evaluation of Hallux Valgus condition is no very reliable.
