Foot Orthoses

Abstract

Orthoses have been broadly used by clinicians to treat mechanical misalignments, such as abnormal foot pronation. As such, the influences of orthoses on lower-limb kinematics have been studied numerous times, with many articles reporting nonsystematic results; the aim of this review, therefore, was to examine the recognized effects of foot orthoses on lower-limb kinematics. The findings from this review suggest that foot orthoses seem to have certain generic and common effects on the lower limb when designed to control rearfoot pronation. We also discuss the possible reasons behind the lack of consistent results between studies. Based on the findings, a list of recommendations is presented for future research on foot orthoses to facilitate comparisons between studies and enable the scientific and clinical communities to better comprehend the effects that these variables might have on the kinematics and, possibly, the treatment outcomes.
