Strong, healthy mobile feet are the foundation of balance and upright movement. The muscular activity of the feet assists in lower limb vascular return, and can be considered the second heart pump.

Developed at the University of Technology, Sydney, the "Archie" feedback tool tests and assists the retraining of the plantar muscles of the foot and ankle. The device aids in exercising the arch muscles for improving foot health and upright functional performance.  With its low cost, ease of use, specifity, real-time feedback, and sensors indicating correct foot placement, Archie should appeal to both the clinical and home-therapy markets.
