Evaluation of ankle mobility in crossfit practitioners with and without patellofemoral pain

Abstract

One of the most common knee injuries related to CrossFit is patellofemoral dysfunction. This dysfunction is characterized by an ill-defined pain of insidious onset, located in the anterior retropatellar region and/or peripatellar knee. Its etiology is multifactorial and can lead to a change in patellar alignment or kinematics during knee flexion-extension movements. The aim of this study was to determine whether there is a difference in ankle range of motion in Closed Kinetic Chain in CrossFit practitioners with and without anterior knee pain. This is a quantitative; cross-sectional; observational; analytical and comparative study and was carried out in CrossFit boxes in a city in the southwest of Bahia with the following stages: (1) recruitment of participants, invitation and referral as accepted or not; (2) selection of participants; (3) data collection that was carried out with each research participant; (4) data analysis and systematization of results. The Lunge Test was used to assess participants aged between 18 and 50. From the data collected, it was not possible to state that ankle mobility deficit in dorsiflexion is a risk factor for the development of patellofemoral dysfunction.
