“Obviously, I'm a huge fan of evidence, but the bulk of what we do is not and will never be evidence-based in that there’s never going to be enough randomized control trials on everything we do; to support everything we do, so then we have to start using things like theoretical coherence, biological plausibility, and most importantly with the available evidence. . .”​

This excerpt from "Planal Dominance" examines the complex, multiplanar movements of foot joints, particularly the subtalar and midtarsal joints, and how variations in joint axis orientation contribute to different foot types and pathologies. The text emphasizes the concept of "planal dominance," explaining how the primary plane of motion in these joints affects overall foot function and compensation. Clinical implications are highlighted, including orthosis design and the relationship between foot mechanics and higher-level joint pathologies. Instrumental and realist theories of foot function are discussed, emphasizing the limitations of simplified models in capturing the complexity of the system.
This cadaveric study investigated the subtalar joint (STJ) neutral position, a crucial concept in foot orthosis fabrication. Researchers challenged the traditional definition of STJ neutral by measuring contact area under axial load in various foot positions. Results indicated that the maximum contact area, signifying true neutral position, occurred at 10° abduction, 20° dorsiflexion, and 10° eversion, differing from the conventional understanding. This finding prompts a reevaluation of established methods for determining STJ neutral and its implications for orthotic treatment. The study highlights the complexities of STJ biomechanics and the need for further research.
