Veel podotherapiestudenten zien het vak biomechanica niet zo zitten. Binnen de opleidingsmuren laaien daarom zo af en toe discussies op in hoeverre biomechanica nodig is voor het vak Podotherapie. Los daarvan heeft de redactie van dit tijdschrift mij gevraagd wat de rol is van de biomechanica bij de …

Veel voetgerelateerde aandoeningen en afwijkingen worden in verband gebracht met drukken onder de voet. Het meten van deze drukken met speciale apparatuur wordt dan ook steeds vaker uitgevoerd door disciplines als podotherapie en orthopedische schoentechniek. Maar: hoe werkt een drukmeting eigenlijk? …

Objective. In this study it was investigated whether an artificial neural network can be used to determine the horizontal, fore-aft component of the ground reaction force from insole pressure patterns. Design. An artificial neural network was applied to map insole pressures and ground reaction forces. …

Objective. In this study an experimental set-up for measuring skin microvascular responses of the footsole to changes in externally applied pressure was analysed. Design. A clinical study. Skin microvascular blood flow was measured in healthy volunteers, during and after external mechanical pressure …

The wrist allows the hand to combine dorsopalmar flexion and radioulnar deviation, a unique combination of functions that is made possible by a highly complex system of joints. The morphologic features of the carpal bones and of the radiocarpal and intercarpal contacts can be functionally interpreted …

The purpose of this study is to create an accurate experimental database for the passive (in vitro)freedom-of-motion characteristics of the human knee joint on a subject to subject basis, suitable for the verification and enhancement of mathematical knee-joint models. Knee-joint specimens in a six degree-of-freedom …

A method to study ligament-length patterns in situ with roentgenstereophotogrammetry, using strings of glued tantalum markers, was developed. The method was tested against a bone-to-bone marking method in five carpal ligaments in three specimens, whereby the hand was moved through dorsopalmar flexion …

In biomechanical joint-motion analyses, the continuous motion to be studied is often approximated by a sequence of finite displacements, and the Finite Helical Axis(FHA) or "screw axis" for each displacement is estimated from position measurements on a number of anatomical or artificial landmarks. When …

Abstract—In many biomechanical motion studies, kinematic parameters are estimated from position measurements on a number of landmarks. In the present investigation, dummy motion experiments are performed in order to study the error dependence of kinematic parameters on geometric factors (number of markers, …
