Effect of marker placement on Oxford Foot Model hindfoot segment axes
نویسندگان
چکیده
Background Measurement accuracy of joint kinematics is influenced by how closely the trajectories of surface markers represent the motion of underlying bones [1]. For the Oxford Foot Model (OFM) hindfoot segment, the heel (HEE), lateral calcaneus (LCA) and sustentaculum tali (STL) markers are used to track the movement of the calcaneus [2]. This paper investigates the how changes in marker placement affect the orientation of the OFM hindfoot segment axes.

Estimation of Midfoot and Ankle Kinetics during Walking
The Oxford Foot model (OFM) [2] is a multi-segment representation of the foot available as a plugin for the Vicon Nexus software package (Vicon, Oxford Metrics, UK). This model represents the foot as three independent rigid segments: The hallux, the forefoot and the hindfoot and computes threedimensional intra-segment kinematics. No kinetic data are provided, however as with the Plugin-gait mod...
متن کاملThe development of a gait shoe for multi-segment foot motion analysis
Multi-segment kinematic foot models quantify foot motion in normal and pathological gait in mainly barefoot assessments, as shoes may confound the marker sets. The aim of this study was to provide a gait shoe to accommodate a multi-segment foot marker set without compromising shoe function. Fifteen normal volunteers and 15 patients with mechanical midfoot pain were recruited. All 30 participant...
متن کاملSensitivity of the Oxford Foot Model to marker misplacement: A systematic single-case investigation.
The purpose of this paper was to systematically assess the effect of Oxford Foot Model (OFM) marker misplacement on hindfoot relative to tibia, and forefoot relative to hindfoot kinematic calculations during the stance phase of gait. Marker trajectories were recorded with an 8-camera motion analysis system (Vicon Motion Systems Ltd., UK) and ground reaction forces were recorded from three force...
متن کاملThe feasibility of a modified shoe for multi-segment foot motion analysis: a preliminary study
BACKGROUND The majority of multi-segment kinematic foot studies have been limited to barefoot conditions, because shod conditions have the potential for confounding surface-mounted markers. The aim of this study was to investigate whether a shoe modified with a webbed upper can accommodate multi-segment foot marker sets without compromising kinematic measurements under barefoot and shod conditi...
متن کاملA Comparison of Two Foot Models Used in Clinical Gait Analysis
INTRODUCTION The location and orientation of talo-crural (TC) and sub-talar (ST) joint axes play an important role in determining foot kinematics and kinetics. The single rigid segment foot model (conventional model) commonly used in clinical gait laboratories contains several significant shortcomings including i) reliance on physical exam based measurements, which are susceptible to significan...
