Physical therapy alters recruitment of the vasti in patellofemoral pain syndrome

Abstract

This study demonstrates that a "McConnell"-based physical therapy treatment regime for PFPS alters the motor control of VMO relative to VL in a functional task and this is associated with a positive clinical outcome.

Hip Strengthening Prior to Functional Exercises Reduces Pain Sooner Than Quadriceps Strengthening in Females With Patellofemoral Pain Syndrome: A Randomized Clinical Trial

“…7,[12][13][14][15]22,39,40,42 However, few of these studies evaluated the efficacy of isolated quadriceps strengthening. Many published rehabilitation protocols target functional exercises in a weight-bearing position, which requires a contribution of both hip and quadriceps musculature.…”

Análise do tempo de resposta reflexa dos músculos estabilizadores patelares em indivíduos com síndrome da dor patelofemural

“…Some studies have analyzed the beginning of voluntary electrical activity of the median and lateral stabilizing muscles of the patella in clinically healthy and individuals with PPS, and have demonstrated synchronism of these muscles under different functional conditions 13 . However, other authors have not observed this synchronism when comparing the beginning of the electrical activity of the (VMO) and vastus lateralis (VL) muscles between normal individuals and those with PPS 2,7 . The beginning of this activity has been used to evaluate the neuromuscular response time of the patellar stabilizing muscles and also how the effect of carrying out treatment protocols on individuals with PPS influences this parameter 12,14,15 .…”

“…The patellofemoral pain syndrome (PPS) frequently affects female athletes, the female sedentary population, and young women are most affected [1][2][3] . This syndrome is present in approximately 25% of orthopedic diagnoses 4 and is defined as a pain at the front of the knee and/or rear of the patella [4][5][6] .…”

“…Although the etiological factors of PPS are not well-defined, some authors have pointed towards biomechanical abnormalities in the lower limbs as the main cause [1][2][3] . Among the biomechanical factors most frequently correlated with the development of PPS, dynamic disequilibrium stands out 1,2 .…”
