Introduction: Kinetic, kinematic and electromyographic activity of the lower limb have been shown to be influenced by various footwear-generated biomechanical manipulations (e.g. soles. Insoles, orthoses). A novel biomechanical device comprising four modular elements attached onto foot-worn platforms was recently developed. Each element can be individually calibrated (Position, convexity, height and resilience) to induce a specific biomechanical challenge.

Objectives: The aim of this study is to evaluate the influence of specific biomechanical challenges on Kinetics, kinematics and electromyographic activity of the lower limb.

Design: Prospective, case control Setting: Motion analyses will be conducted during level walking with (1) a three-dimensional motion analysis system and (2) ground reaction force analysis using force platforms (3) Electro-Myography system. Each subject will be examined in 16 different settings of the biomechanical system
