“…However, there are different opinions on the existence or flexibility of FTA [9][10][11][12][13]. According to Kapandji, alignment of FTA elevates the 2nd to 4th metatarsal heads (MTH) [9], while in another study, the peak plantar pressure occurred under the 2nd, 3rd and 4th MTH during normal gait [10][11][12], which denies the existence of FTA during the stance phase.…”

“…We hypothesized that a reason behind this disagreement is the lack of integrated measuring methods. For the measurement of FTA, various methods are used such as plantar pressure measurements [10][11][12], 3D surface scan [14] and X-ray photography [13]. However, plantar pressure measurements and 3D surface scan cannot evaluate the shape of MTH, hence denying the existence of FTA.…”

Objective: Most studies on arch biomechanics focus on the medial longitudinal arch (MLA) and its function; however, there are fewer studies on the forefoot transverse arch (FTA) biomechanics and its function is not well understood. This study aimed at investigating the function of FTA on foot kinetics and kinematics during gait. Methods:Nineteen healthy participants (10 men, 9 women) with a mean age of 25.8 years were recruited. Each measurement was performed with the participants' dominant foot. For evaluating FTA, transverse arch index (TAI) was measured using ultrasonic diagnostic equipment, which represented the relative height of FTA. Measurements were performed in a two-stance condition: 90% of weight bearing (90% WB), and 10% of weight bearing (10% WB). For evaluating MLA, arch height ratio (AHR) were measured with a ruler. A three-dimensional motion analysis system was used to capture and analyze foot kinetics and kinematics. Participants were instructed to walk barefoot along a 7 m walkway at regular walking pace (110 steps/minute). To examine the function of FTA, spearman's correlation coefficients were calculated for non-parametric variables (TAI at 10% WB with foot kinetics and kinematics), to examine the relationship between MLA and FTA, (TAI at 10% WB with AHR), to examine flexibility of FTA, (the difference between TAI in 90% and 10% WB with vertical ground reaction force (GRFV)in the terminal stance).Results: A significant positive correlation was observed between TAI and max GRFV in the terminal stance (r=0.50, P=0.03). There was no significant difference between TAI at 10% WB and AHR, A significant negative correlation was observed between the difference in TAI at 90% and 10% WB and, max GRFV in the terminal stance (r=-0.64, P=0.003). Conclusions:The present study showed that GRFV in the terminal stance was positively correlated with the height of FTA, and that flexibility of FTA has relative to GRFV in the terminal stance during gait. It is important to measure flexibility of FTA as well as height of FTA so as to predict the risk of forefoot injury.

“…It is widely accepted that the metatarsal heads constitute an arch also in the anterior-posterior plane, generally known as Le Lie`vre's metatarsal parabola in which the second metatarsal bone is relatively longer in comparison to remaining metatarsal bones [16], and is deeply wedged in-between the first and third cuneiforms.This makes the second meatarsal bone relatively fixed, with only dorsiflexion and plantarflexion movement being possible, in contrast to the other metatarsal bones which can also perform rotational movements. For this reason the second metatarsal bone is considered to be the central part of the metatarsus.…”

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.

“…Previous techniques that have been developed for measuring the transverse arch of the forefoot include plantar pressure measurements [1][2][3] , ultrasonography 4,5) , and X-ray photography 6) . In plantar pressure measurements, dropping of the transverse arch of the foot is indicated by the concentration of plantar pressure on the 2 nd or 3 rd metatarsal heads.…”
