An ABI seminar by Dr Desney Greybe, Research Fellow at the Auckland Bioengineering Institute.


The dexterity of the upper limb is made possible, in part, by the ability to rotate the hand. That rotation is achieved within the forearm. Relatively little is understood of either the kinematics or kinetics of forearm rotation, nor is distal radioulnar joint contact properly understood. As a consequence, the outcomes when treating disorders and injuries of the forearm are often inconsistent, particularly as they relate to distal radioulnar joint health. The goal of my research was to investigate forearm kinematics and the contributions various muscles make to forearm rotation. The results of these analyses were combined with a detailed continuum model to examine distal radioulnar joint contact throughout the forearm range of motion and under simulated clinical conditions.


Desney completed a Bachelor of Science at the University of Auckland in 2007, double majoring in Sport and Exercise Science and Psychology. He received a Bachelor of Science with Honours in Sport and Exercise Science from the University of Auckland in 2008. His Honours dissertation used kinematic, biomechanical analysis to evaluate how effectively particular psychological interventions improved golf-swing technique.

In 2010, Desney began a doctoral degree at the Auckland Bioengineering Institute. His thesis title was "Finite element modeling of distal radioulnar joint articulation," and he completed it in 2015.
