Active regulation of longitudinal arch compression and recoil during walking and running
TL;DR: This work tests the hypothesis that intrinsic foot muscles, abductor hallucis, flexor digitorum brevis, FDB and quadratus plantae, actively lengthen and shorten during the stance phase of gait in response to loading of the foot, and provides the first in vivo evidence that the plantar intrinsicFoot muscles function in parallel to the plantAR aponeurosis.

Human-like external function of the foot, and fully upright gait, confirmed in the 3.66 million year old Laetoli hominin footprints by topographic statistics, experimental footprint-formation and computer simulation

TL;DR: In this paper, Pixel-wise topographical statistical analysis of Laetoli footprint morphology, compared with results from experimental studies of footprint formation; foot-pressure measurements in bipedalism of humans and non-human great apes; and computer simulation techniques, indicate that most of the major functional features of the human foot were already present, albeit less strongly expressed than in ourselves, in the maker of the G-1 footprint trail, 3.66 Mya.

TL;DR: Investigating the twisted structure of the AT at the level of fascicles that originate from the MG, LG, and Sol, and elucidate the morphological characteristics provides promising basic data to elucidates the functional role of the Twisted structure and mechanisms for the occurrence of AT injury and other conditions.

Kinematics of the ankle and foot. In vivo roentgen stereophotogrammetry.
TL;DR: In this article, the authors used Roentgen stereophotogrammetric analysis to study ankle/foot kinematics in eight healthy volunteers and found that plantar flexion/dorsiflexion and pronation/supination of the foot as well as internal/external rotation of the leg.
Journal ArticleDOI
Analysis of a kinetic multi-segment foot model. Part I: Model repeatability and kinematic validity
TL;DR: A three-segment kinetic foot model is presented and thorough evaluation of model performance during normal gait and segment rigidity analysis suggested rigid body behavior for the Shank and Hindfoot, with the Forefoot violating the rigid body assumptions in terminal stance/pre-swing.

Position and orientation in space of bones during movement: experimental artefacts.
Aurelio Cappozzo,Aurelio Cappozzo,Fabio Catani,Alberto Leardini,Maria Grazia Benedetti,U. Della Croce +5 more
TL;DR: The experimental problems related to the reconstruction of the position and orientation of the lower limb bones in space during the execution of locomotion and physical exercises and inaccuracies associated with the relative movement between markers and underlying bone are analysed.
Journal ArticleDOI
Rear-foot, mid-foot and fore-foot motion during the stance phase of gait
TL;DR: A new protocol designed to track a large number of foot segments during the stance phase of gait with the smallest possible number of markers, with particular clinical focus on coronal plane alignment of the rear-foot, transverse and sagittal plane aligning of the metatarsal bones, and changes at the medial longitudinal arch is proposed.

Kinematic analysis of a multi-segment foot model for research and clinical applications: a repeatability analysis
TL;DR: A protocol for evaluation of foot kinematics during barefoot walking based on a multi-segment foot model is developed and it is found that repeatability is primarily subject to variability of marker placement more than inter-tester variability or skin movement.
Journal ArticleDOI
A system for the analysis of foot and ankle kinematics during gait
TL;DR: A five-camera Vicon motion analysis system was used and the Euler method for describing relative foot and ankle segment orientation was utilized in order to maintain accuracy and ease of clinical application.

Foot kinematics during walking measured using bone and surface mounted markers.

TL;DR: It is unlikely that one rigid body foot model and marker attachment approach is always preferable over another, as differences between the data from the skin and plate protocols were consistently smaller than differences between either protocol and the kinematic data for each bone comprising the segment.
