Plantar pressure assessment is a tool useful for study of the gait cycle. In this study, we present a means of assessing the gait cycle using a temporal analysis of plantar pressures and lower-leg muscle activities. Plantar pressures and surface electromyography (EMG) of the tibialis anterior (TA) and medial gastrocnemius (MG) muscles were recorded as 19 men walked on a treadmill at seven speed...

Racehorses are susceptible to underrun heel hoof conformation. often shod with nails placed toward the heel. It is unknown if palmar restrict or alter deformation in a manner that could promote development of conformation over time repeated loading. To determine how addition affects during limb loading, expansion and wall deformations were quantified using rosette strain gauges kinematic marker...

abstract introduction: in some individuals because of the poor functioning leg muscles, plantar arch drooping suffered and it seems that ground reaction force individuals with flat foot than to those with normal foot, due to reduced recruitment is altered by the arc. the aim of  the present study the effect of corrective exercise program on the ground reaction force of student with flat food du...

BACKGROUND Obstacle crossing is impaired in people following stroke. It is not known whether people with stroke who fail an obstacle crossing task have more falls or whether the gait adjustments used to cross an obstacle differ from those used by people who pass the task. OBJECTIVE The purposes of this study were (1) to identify whether a group of people with stroke who failed an obstacle cro...

in this theoretical study, the effect of various types of bypass graft angles on the flow field, has been investigated specially on the temporal wall shear stress (wss) on the toe, heel and some locations on the bed of the left anterior descending (lad) artery at the anastomoses areas in the aorto-coronary (ac) and coronary-coronary (cc) bypasses. flow fields in both bypasses with angles of 20º...

Biomechanical analysis of gait is commonly used in physiotherapy. Ground reaction forces during phases one element kinetic analysis. In this article, we analyze if the MoveSole® smart insole valid and accurate equipment for measuring ground clinical StepLab a mobile measurement system instant underfoot force measurements gait. Unique electromagnetic film (EMFI) based sensor technology printed e...

The foot is an important element of the locomotor apparatus and performs a number functions in our body. Abnormalities its shape can affect everyday functioning. Therefore, it worth paying attention to proper development feet children. aim study was assess dynamics changes selected parameters younger children school age. involved 70 observations were conducted twice same children, aged 5 9 year...

OBJECTIVE A growing exercise culture has lead to an increase in the use of off-the-shelf heel inserts. While there are a variety of designs in a spectrum of cost ranges, probably the ease of availability and cost would mainly determine the choice of purchase. This study was designed to determine whether expensive designs provide better pressure attenuation under the heel than their less expensi...

Most clinically available prosthetic feet have a rigid attachment or incorporate an "ankle" device allowing elastic articulation during stance, with the foot returning to a "neutral" position at toe-off. We investigated whether using a foot with a hydraulically controlled articulating ankle that allows the foot to be relatively dorsiflexed at toe-off and throughout swing would increase minimum ...

Friction-induced moments and subsequent cup loosening can be the reason for total hip joint replacement failure. The aim of this study was to measure the in vivo contact forces and friction moments during walking. Instrumented hip implants with Al2O3 ceramic head and an XPE inlay were used. In vivo measurements were taken 3 months post operatively in 8 subjects. The coefficient of friction was ...
