Analysis on the activation of the VMO and VLL muscles during semisquat exercises with and without hip adduction in individuals with patellofemoral pain syndrome

Activation of VMO and VL in Squat Exercises for Women with Different Hip Adduction Loads

“…We found that the VMO muscle activity increased in squat exercises with hip adduction compared to the conventional squat exercise. This result agrees with the findings of previous studies, in which the VMO muscle showed significantly greater electrical activity during a double leg semisquat exercise associated with hip adduction 5,11) . Some researchers also reported that squat exercises with maximal adduction of the hip showed an increase in the myoelectrical activity of VMO 7,11) .…”

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

“…They underwent functional evaluations and were divided into two groups: a control group of clinically healthy women (n= 12), with a mean age 22.7 years (±2.25) and mean height of 165 cm; and a group with PPS (n= 12), with a mean age 22.0 (±2.04) years and mean height of 158 cm. The inclusion criteria for the PPS group were: previous reports of pain at the front of the knee during functional activities 2 ; no pain reported for at least the last two months; and presence of three or more clinical signs and symptoms observed during the functional evaluation 18 . The exclusion criteria for the PPS group were: reports of a history of surgery, trauma and osteomyoarticular system injuries to the hip, ankle and foot; use of medications or previous physical therapy treatment less than six months before the time of the present study; and neurological diseases.…”

Efeitos da eletroestimulação do músculo vasto medial oblíquo em portadores de síndrome da dor patelofemoral: uma análise eletromiográfica

“…The EMG parameter demonstrated by the integral of the signal indicates the total energy consumed by the muscle during the activity. It has been commonly applied for analysis due to its relation to the force employed by the muscle during the performance of a given task 15,[27][28][29][30] . Despite the consensus on the use of electrical stimulation to improve resistance and muscle strength, there are few studies on its effect on PFPS [9][10][11][12][13]30 .…”
