Effects of the slow speed-targeting squat exercise on the vastus medialis oblique/vastus lateralis muscle ratio. [PDF]

J Phys Ther Sci, 2015
[Purpose] This study investigated the effects of the slow speed-targeting squat exercise on the vastus medialis oblique/vastus lateralis ratio. [Subjects] Ten asymptomatic men were recruited. [Methods] The EMG activities of the vastus medialis oblique and vastus lateralis muscles were recorded using surface electrodes.

Structural determinants of quadriceps atrophy following ACL injury: Evidence for fibre atrophy without fibre loss or overt peripheral denervation. [PDF]

J Physiol
Abstract figure legend Quadriceps atrophy after ACL injury is characterized by reduced muscle fibre cross‐sectional area without evidence of fibre loss or overt denervation. Reductions in whole‐muscle size are explained by decreases in muscle fibre cross‐sectional area, while neuromuscular junctions (NMJs) remain structurally and functionally intact ...

Comparison of Two Different Modes of Active Recovery on Muscles Performance after Fatiguing Exercise in Mountain Canoeist and Football Players. [PDF]

PLoS ONE, 2016
The aim of this study is to assess if the application of different methods of active recovery (working the same or different muscle groups from those which were active during fatiguing exercise) results in significant differences in muscle performance ...

ELECTROMYOGRAPHIC ACTIVITY OF THE VASTUS MEDIALIS OBLIQUE AND VASTUS LATERALIS DURING MAXIMUM VOLUNTARY ISOMETRICS IN DIFFERENT WEIGHT BEARING POSITIONS OF THE FOOT

International Journal of Physiotherapy, 2014
Background: Patellofemoral pain syndrome is a very common disorder. 90% of the general population has some degree of pathologic changes of the patellofemoral joint. Knowledge regarding the cause and prevention of patellofemoral pain syndrome is essential.

Activation of the vastus medialis oblique and vastus lateralis muscles in asymptomatic subjects during the sit-to-stand procedure. [PDF]

J Phys Ther Sci, 2015
[Purpose] The purpose of this study was to examine the vastus medialis oblique to vastus lateralis ratio in two pelvic tilt positions while performing the sit-to-stand task. [Subjects and Methods] Activation of the vastus medialis oblique and the vastus lateralis muscles of 46 healthy subjects (25 males, 21 females) were recorded by surface ...

Muscle Synergy Alteration of Human During Walking With Lower Limb Exoskeleton

Frontiers in Neuroscience, 2019
Muscle synergy reflects inherent coordination patterns of muscle groups as the human body finishes required movements. It may be still unknown whether the original muscle synergy of subjects may alter or not when exoskeletons are put on during their ...

Improvement of Pain and Function by Using Botulinum Toxin Type A Injection in Patients with an Osteoarthritic Knee with Patellar Malalignment: An Electromyographic Study

Life, 2022
Objective: To determine the pain and electromyographic (EMG) amplitude ratio of the vastus medialis oblique (VMO) to the vastus lateralis (VL) after botulinum toxin type A (BTA) was injected in the bilateral osteoarthritic knee of patients with patellar ...

PREFERENTIAL VASTUS MEDIALIS OBLIQUE ACTIVATION ACHIEVED AS A TREATMENT FOR KNEE DISORDERS

Journal of Strength and Conditioning Research, 2005
The purpose of this study was to compare the effect of an open-stance cycling protocol (OSCP) with the traditional cycling foot position (TCFP) for preferential vastus medialis oblique (VMO) muscle activation, measured by surface electromyography (SEMG), and preferential VMO activation as defined by achieving significantly increased VMO/VL (vastus ...
