White Paper: Foot Pronation

Over the past decades, pronation has been discussed as a potential risk factor for injuries or as the mechanism behind impact damping. However, little is understood about pronation. The objectives of this paper were to (a) define and differentiate between the terms of pronation and eversion, (b & c) underline the importance and problematic aspects of pronation.

Study Shows Heel Lifts Affect Biomechanics, Muscle Function

Clinicians use a variety of in-shoe heel lifts to treat a range of musculoskeletal conditions. The mechanics of how these orthotic devices work, however, is unclear. So a group from LaTrobe University in Australia put together a study that asked this question: Do heel lifts affect lower limb biomechanics and muscle function during walking and running?

1064-nm Laser Technique Shows Positive Results for Onychocryptosis

Onychocryptosis, more commonly known as in-grown toenail, affects nearly 20% of all patients who present a foot problem to their doctor. Current treatments include incisional procedures and nonincisional procedures, such as chemical matrixectomies and physical matrixectomies using a carbon dioxide laser.
