OBJECTIVE To determine the kinematic, kinetic and EMG responses to perturbations of the foot by running in varus, neutral, and valgus-wedged shoes. DESIGN Within-subjects study comparing kinematics, kinetics and EMG while running in three different shoe conditions. BACKGROUND Excessive pronation has been cited as a key contributor to many types of running injuries. However, the roles of the...

an experimental study of the phase inversion behavior of liquid-liquid dispersion has been conducted in a spray extraction column for systems of toluene / water, n-hexane/water, ccl4/water, toluene /water + glycerol (25 % wt), toluene + ccl4 (25 % wt) / water and toluene / acetic acid (5 % wt)/water. the effects of physical properties, mass transfer and column geometry on phase inversion have b...

A novel dimensional synthesis technique for solving the mixed exact and approximate motion synthesis problem for planar RR kinematic chains is presented. The methodology uses an analytic representation of the planar RR dyad’s rigid body constraint equation in combination with an algebraic geometry formulation of the exact synthesis for three prescribed positions to yield designs that exactly re...

The objective of this study is to validate previous descriptions of hindfoot kinematics using dual Euler angle methods in a passive cadaveric model. The dual Euler angle method was chosen so as to facilitate description of the translational and rotational movement occurring at both the ankle and subtalar joints. A non-metal experimental set-up was fabricated to generate motion in foot cadaver s...

‘I’/& paper proposes technique for automaticall~ identifying and modeling the kinematic wwtminta of manipulated objects. The existence of wn.druints is established by examination of the forces and torques normal and tangential to the object’s motion. Constraints are modeled as joints tuith wnfigumtion and history dependent forca. To illustmte these concepts, seveml experimental examples are pre...

The purpose of this study was to clarify the characteristics lower-extremity kinematics during running soccer players with chronic ankle instability (CAI) in comparison those without CAI. Twenty-two male college participated study. Twelve were assigned CAI group and ten non-CAI group, diagnosed according Cumberland Ankle Instability Tool. Kinematic data hip, knee, ankle, foot, ground reaction f...

Objectives: The aim of this study was to extract suitable spatiotemporal and kinematic parameters to determine how Total Knee Replacement (TKR) alters patients’ knee kinematics during gait, using a rapid and simplified quantitative two-dimensional gait analysis procedure. Methods: Two-dimensional kinematic gait pattern of 10 participants were collected before and after the TKR surgery,...

A devasting Mw7.2 earthquake struck southern Haiti on 14 August 2021, leading to over 2000 casualties and severe structural failures. This earthquake, which ruptured ~70 km west of the 2010 Mw7.0 event, offers a rare opportunity probe mechanical properties Haiti. study investigates kinematic multi-fault coseismic rupture process by jointly analyzing teleseismic interferometric synthetic apertur...

the momentum equation in the kinematic wave model is a power-law equation with two parameters. these parameters, which relate the discharge to the flow area, are commonly derived using manning’s equation. in general, the values of these parameters depend on the flow depth except for some special cross sections. in this paper, improved estimates of the kinematic wave parameters for circular chan...
