Fatigue and the Electromechanical Efficiency of the Vastus Medialis and Vastus Lateralis Muscles [PDF]

open access: yesJournal of Athletic Training, 2008
AbstractContext:The relationship between the amplitudes of the mechanomyographic (MMG) and electromyographic (EMG) signals has been used to examine the “electromechanical efficiency” (EME) of normal and diseased muscle. The EME may help us to better understand the neuromuscular relationship between the vastus medialis and vastus lateralis muscles ...

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

open access: yesJournal 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]

The role of the quadriceps muscle in knee extension

open access: yesSouth African Journal of Physiotherapy, 1983
In 1949, Smillie proposed that the vastus medialis muscle alone is responsible for the final 10° to 15° of knee extension. A number of more recent studies have proved that the whole quadriceps muscle is responsible for all degrees of knee extension. This

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

open access: yesMedicine & 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.

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

open access: yesThe 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.
