"Excessive" pronation is often implicated as a risk factor for anterior knee pain (AKP). The amount deemed excessive is typically calculated using the means and standard deviations reported in the literature. However, when using this method, few studies find an association between pronation and AKP. An alternative method of defining excessive pronation is to use the joints' available range of m...

Running efficiency is an important factor to consider in order to avoid injury. In particular, foot pronation, the angle of the foot as it hits the ground, is a common cause for many types of injuries amoung runners. Though pronation is common, diagnosing pronation is difficult and imprecise. Currently there is no method of diagonsis which can quantify the severity of pronation. In this paper w...

HYPOTHESIS Does metatarsal pronation exist and, if so, what is its impact? INTRODUCTION Hallux valgus is a deformity associating angulation and a rotational component. The present study sought to investigate the nature and origin of the coronal plane displacement. MATERIALS AND METHODS A prospective single-center radiological and anatomic study was conducted on 100 feet operated on for hall...

Background Excessive foot pronation during gait is frequently linked to patellofemoral pain syndrome (PFPS) development, due a proposed coupling of increased foot pronation with increased tibial and femoral internal rotation. However, there is a paucity of research which has compared kinematics associated with foot pronation between individuals with PFPS and controls. The aim of this study was ...

Despite extensive research on running mechanics, there is still a knowledge gap with respect to the degree of relationship between mediolateral ground reaction forces (ML-GRF) and foot pronation. Our goal was to investigate whether differences exist in ML-GRF among runners that exhibit different degrees of pronation. Seventeen male and 13 female recreational runners ran with and without shoes w...

Objectives: Pronation distortion syndrome is one of the common physical deformities, that causes distortions in the skeletal structures of the feet. The current study aimed to determine the effects of 12 weeks of systematic and functional corrective exercises on the body posture of students with pronation distortion syndrome.  Methods: In this quasi-experimental study, 30 volunteers suffering ...

PURPOSE To show biomechanically that the brachioradialis (BR) muscle can be transferred to restore key pinch and forearm pronation simultaneously. METHODS Nine fresh-frozen forearms were thawed and instrumented with a custom muscle-tendon excursion jig. Maximum BR muscle-tendon excursion was measured with the wrist and thumb mobile. Muscle-tendon excursion then was measured from 60 degrees of...

Many overuse injuries of the lower extremity are associated with excessive/prolonged pronation of the foot during gait. Pronation is a complex motion and its quantification during gait has mainly been limited to rearfoot motion. However, foot pronation also occurs across the more distal joints of the foot. Thus it is pertinent to quantify both rearfoot and forefoot motion when assessing pronati...

Excessive foot pronation has been considered to be related to anterior knee pain. We undertook a prospective study to test the hypothesis that exertional anterior knee pain is related to the static and dynamic parameters of foot pronation. Two weeks before beginning basic training lasting for 14 weeks, 473 infantry recruits were enrolled into the study and underwent two-dimensional measurement ...
