Exploring Innovations in Orthotic Insole Design: An Interview with Researcher Dayna Cracknell

journal cover

In the realm of biomechanics, understanding how different materials influence in-shoe pressure distribution is crucial for enhancing orthotic insole design. A recent study titled "The Mechanical Response of Polymeric Gyroid Structures in an Optimised Orthotic Insole" delves into this subject, utilizing the F-Scan GO system to measure plantar pressure differences. 

The research studied the mechanical behavior of different configurations of materials - gyroid structures - used in making orthotic insoles. The aim was to find the best method to form this material to reduce peak planter pressures. The researchers used the F-Scan GO system to measure the planter pressure differences in test subjects using the insoles.

We had the opportunity to speak with one of the authors of this paper, Dayna Cracknell, a Doctoral Candidate at The University of Auckland in New Zealand, about her research and the role of the F-Scan GO in her work.

Responses lightly edited for clarity.

Tekscan: Congrats on your PhD submission! What got you interested in studying orthotics?

Dayna Cracknell: "Thank you! I have always been interested in the bridge between healthcare and mechanical engineering and was dabbling in 3D printing. This was such an easy choice because every part of the project was interesting to me!"

Could you summarize the key findings from your study?

"My PhD looked at an orthotic insole made of a fluid filled lattice, with the idea being that the fluid could help even out the pressure distribution on the bottom of the foot in real time. Our findings indicate that it worked: that incorporating fluid into the insole enhanced its performance throughout the gait cycle."

Why did you choose the F-Scan™ GO system to assist your research, and how did it facilitate your data collection? 

"Firstly, we were seeing a lot of other researchers in a similar space using this system, so we knew that it was well regarded. Additionally, our lab has a large collection of Tekscan pressure mats – some of them are very old (I would say at least 20 years) and they still work great (even though they have seen a LOT of wear and tear!) so we could assume that the F-Scan GO system would last a long time. We were also familiar with the old system, so it felt like a good move."
