Lower-Extremity Muscle Activity, Kinematics, and Dynamic Postural Control in Individuals With Patellofemoral Pain

Abstract

There were alterations in muscle activity during SEBT performance, suggesting that overactivity of AL relative to GMED is a unique neural recruitment pattern in those with PFP. However, hip and knee joint kinematics did not seem to contribute to deficits in the anterior reach distance, suggesting a need for continued assessment of these deficiencies.

Patellofemoral Pain Syndrome and Its Effect on the Walking of Affected Subjects: Update Review

“…Also, the most important results from the kinetic parameters mentioned in the study by Arazpour et al [26] included increase contralateral pelvic drop and hip adduction reduce knee extensor moment and delayed peak rear foot eversion during gait (Tables 2 and 3). The finding of this study demonstrated that knee valgus displacement was significantly increased in subjects with PFPS compared to healthy subjects 68 H Goto et al [2] Case-control 14 PFP Hip flexion/adduction/internal rotation They found that there is no significant difference between kinematic parameters in patients with patella femoral pain syndrome compared to healthy subjects (p>0.05) 14 H Knee flexion/abduction/internal rotation Table 3: New studies investigating the effects of patella femoral pain syndrome on gait parameters.…”

“…Patellofemoral pain syndrome (PFPS) is one of the disorders that are related to the knee joint which includes 10 to 25 percent of knee injuries [1,2]. The incidence of this complication is estimated to be between 7% and 15% in young adults in military [3].…”

The Effects of 12-Weeks of Sensorimotor Exercise on Pain, Strength, Pelvic Drop, and Dynamic Knee Valgus in Males With Patellofemoral Pain Syndrome

“…At this stage, the patient lied on his back on the examination table and the distance between the anterior superior iliac spine up to malleus internal was recorded a s the lower limb length. This evaluation was performed for both limbs [14].…”

“…The calibration of the HHD was established before the study by placing a specific weight on the HHD and comparing it with the weight indicated by it [22]. Before running the experiment, the study patients performed two sub-maximal contractions to become familiarized with the method [14].…”

“…To assess hip abductor muscle strength, the patient was placed in a sidelying position on the treatment table with the testing limb on top. The examiner checked the limb to assure the lack of external rotations or extensions and placed a pillow between the legs to neutralize the hip position [14]. The tester placed HHD on the lateral femoral condyle and the patient performed the maximum isometric contraction [23].…”
