Gender differences in electromyographic activation of some lower extremity muscles in subject with and without genu varum abnormality.

مجله پژوهش در علوم توانبخشی, 2014
Introduction: mal-alignment of lower extremity especially at the knee can lead to injury due to impact on muscle activity and proprioception. Therefore the aim of present study was the gender differences of some lower extremity muscle activation in ...

Spinal Reflex Arc Excitability Corresponding to the Vastus Medialis Obliquus and Vastus Medialis Longus Muscles

Journal of Physical Therapy Science, 2014
[Purpose] The gross morphology of the vastus medialis (VM) muscle has been thoroughly described. However, there is insufficient evidence of physiological differentiation between the VM obliquus (VMO) and VM longus (VML). To elucidate spinal reflex arc excitability in two divisions of the VM, we compared H-reflexes and T-waves in VMO and VML. [Subjects]

Regional Vastus Medialis and Vastus Lateralis Activation in Females with Patellofemoral Pain [PDF]

Medicine & Science in Sports & Exercise, 2019
ABSTRACT Introduction This study aimed to investigate whether regional activation patterns in the vasti muscles differ between females with and without patellofemoral pain (PFP), and whether muscle activation patterns correlate with knee extension strength.

Is it truly impossible to strengthen the vastus medialis in isolation from the entire quadriceps muscle group?

Heliyon
Background: To date, no specific exercises have been designed to selectively strengthen the vastus medialis muscle. Therefore, the purpose of this research is to provide a clear answer to the question: Is it truly impossible to strengthen the vastus ...

Regionalization of the stretch reflex in the human vastus medialis [PDF]

The Journal of Physiology, 2017
Key points Regionalization of the stretch reflex, i.e. the notion that the activation of 1a afferents from a muscle region influences only the activation of motor units in the same region, has been demonstrated previously in animals but not in humans.

Kinematic and Neuromuscular Measures of Intensity During Drop Jumps in Female Volleyball Players

Frontiers in Psychology, 2021
The aim of this study was to assess drop jump (DJ) performance variables (jump height, contact time, and reactive strength index) concomitant to surface electromyography (sEMG) of lower limb muscles during DJs from different drop heights (intensities ...

Knee and Hip Joint Kinematics Predict Quadriceps and Hamstrings Neuromuscular Activation Patterns in Drop Jump Landings. [PDF]

PLoS ONE, 2016
PURPOSE:The purpose was to assess if variation in sagittal plane landing kinematics is associated with variation in neuromuscular activation patterns of the quadriceps-hamstrings muscle groups during drop vertical jumps (DVJ).

The Vastus Medialis Insertion Is More Proximal and Medial in Patients With Patellar Instability: A Magnetic Resonance Imaging Case-Control Study

Orthopaedic Journal of Sports Medicine, 2019
Background: The anatomy and function of the quadriceps muscle play a role in patellofemoral stability. Few studies have evaluated anatomic differences in the vastus medialis between patients with and without patellar instability.
