“…According to Kantali, the central part of the foot is predominantly subjected to the greatest loads, as confirmed in 63.3% of the participants in his research [11]. The current study affirms Kantali's observations.…”

“…Two indicators were selected, i.e. Indicator 1: Kantali metatarsal bone pressure distribution pattern (arrangement of heads of metatarsal bones based on their maximum pressures on the ground) M 1 <M 2 >M 3-5 -the second metatarsal bone head subjected to the most intensive pressure, with lower pressure put on the remaining metatarsal bone heads, M 1 ≥M 2 >M 3-5 -the greatest pressure found on the first metatarsal bone head, or equally, on the first and the second metatarsal bones, with lower pressure between the third and the fifth, M 1 <M 2 ≤M 3-5 -the greatest pressure put on metatarsal bones heads between the third and the fifth, or equally distributed between the third and the fifth, as well as the second metatarsal bones heads, M 1 >M 2 <M 3-5 -the lowest pressure made on the second metatarsal bones head, with major pressure put on the remaining metatarsal bones heads (functional transverse arch) [11]; and Indicator 2: Longitudinal arch index according to Cavanagh (relation between full metatarsus (masks 3 and 4) contact surface and a sum of whole foot surface contact area, excluding toes (masks 1-7) (Fig. 1) [12].…”

Introduction. Both walking and its faster, running, consist of cyclical subsequent phases of swing and support; however, they differ in their time proportions as well as magnitude of acting forces. There is a lack of studies concerning the longterm consequences of repeated jogging cycles on the function of feet and, above all, on their permanent impact on the shape of foot arches. Objectives. The objective of this study was to answer the question whether regular jogging changes the shape of the transverse and medial longitudinal arches of the feet. Materials and method. The research material consisted of 96 women with an average age of 26.57, and included 50 actively jogging women, and 46 of non-joggers. The study was performed with the use of EMED-SF force platform. The plantar surface of the foot was divided into 10 regions according to Cavanagh, for which peak pressure and contact time were established. Two indicators were defined: metatarsal bone pressure distribution pattern acc. to Kantali, and longitudinal arch index acc. to Cavanagh. Results. The data obtained revealed more frequent occurrence of the greatest pressure under the centrally located metatarsal heads (lack of functional foot transverse arch) among the female joggers, compared with the non-joggers. Moreover, the findings indicate the higher frequency of medial longitudinal foot arch flattening among female runners, with a great deal of consistency between both feet, whereas results for the control group show asymmetrical medial arch shapes with right foot propensity to normal arch shape and left foot tendency for excessive arch. Conclusion. The observed differences in feet arch shapes between female joggers and non-joggers indicate the influence of jogging on feet functional adaptations.

“…The maximum numbers of lesion was present in the region of second to fifth metatarsal (53.33%), followed by heel (26.66%) and great toe (10%) with no lesion on midfoot. Various studies have evaluated the role of obesity, 27 different load carrying conditions, 28 simulated changes in body mass, 29 or body mass as a correlate to peak plantar pressure [30][31][32][33] but showed no consensus in the regional areas affected by body mass when peak plantar pressure has been measured. However there is direct relationship between increasing body mass and dynamic peak plantar pressure in different regions.…”

“…Wearing és mtsai szerint a test zsírtömege és a lábstruktúra megváltozása állhat a nagyobb kontakt terület hátterében [9]. Korábbi tanulmányok az előláb fokozott terheléséről számolnak be elhízottaknál [5,[33][34][35]. Vizsgálatunkban is a metatarsusok alatt a csúcsnyomás elhízottaknál jelentősen magasabb értékeket mutatott, lateralisan 22%-kal, medialisan 15%-kal, mint a normál súlyú alanyoknál.…”

Bevezetés: A testsúlynak jelentős szerepe van a láb megnövekedett terhelésében és a nyomásminták változásaiban, de a változások eloszlása pontosan nem ismert. Célkitűzés: Jelen kutatás célja volt normál és kóros testtömegindexű egyének talpnyomásmintáinak vizsgálata, hogy közelebbi képet kapjunk a regionális plantaris terhelés változásairól. Módszer: A vizsgálatnak 180 alanya volt, a talpnyomás mérése dinamikus pedobarográffal történt. A talp 8 anatómiai régióját vizsgáltuk, az alábbi paraméterek függvényében: kontakt terület, csúcsnyomás, maximális erő. Eredmények: A láb középső területén és metatarsusok alatt jelentősen nagyobb csúcsnyomás jellemző az elhízott egyénekre (p<0,001). A maximális erőértékek az ujjaknál alacsonyabb (p<0,001), a kontakt terület adatai a totális talpterületen (p<0,001) és a középső talp területén szignifikánsan nagyobb értékeket mutatott az elhízottak csoportjában (p<0,001). Következtetések: Elhízás hatására kóros mértékű terhelésnövekedés következik be a láb középső területén, különösen a medialis oldalon és a metatarsusok alatt. Orv.

Kulcsszavak: elhízás, talpnyomásminták, medialis hosszboltozat Analysis of plantar pressure patterns among obese populationIntroduction: Although the role of body weight on foot health and load has been widely documented in research, the effect of the extra load due to body weight on plantar pressure characteristics is not well known. Aim: The aim of this study was to evaluate the impact of obesity on plantar pressure patterns among the working-age population. Method: 180 participants were involved. Two groups were evaluated according to body mass index categories regarding eight regions of the plantar area, focusing on the following parameters: contact area, maximum pressure and peak pressure. Results: Compared with non-obese subjects, the peak pressure was the highest on the midfoot (p<0.001) and the forefoot (p<0.001). Regarding the maximum force, significant statistical difference was detected on the toes (p<0.001), with a value lower among the obese group. The contact area on the total foot and the midfoot was lower among the non-obese subjects (p<0.001). Conclusions: Loading is greatly increasing on the whole plantar area, especially at the midfoot and the forefoot region.

Pressure distribution patterns under the metatarsal heads in healthy individuals

Abstract: Our data show that there are four distinct pressure distribution patterns, but the greatest plantar pressure occurs in the middle column of the foot in the majority of healthy individuals.
