The biomechanics and clinical efficacy of footwear adapted with rocker profiles--evidence in the literature.

Abstract

Efficacy is demonstrated with regards to relief of forefoot plantar pressures. However, the definitive profile shape has not been demonstrated. The effectiveness of rocker-soled shoes in restricting sagittal plane motion in individual joints of the foot is unclear. Rocker profiles have minimal effect on the kinetics and kinematics of the more proximal joints of the lower limb, but more significant effects are seen at the ankle. Further research is warranted on the effects of rocker profiles on individual joints of the foot and the manner in which they effect lower limb muscle activity and gait patterns.
