Conflicting results have been reported on whether closed kinetic chain exercises (such as a
leg press) may induce more balanced activation of vastus medialis (VM) and lateralis (VL) …

Background: Rehabilitation programs for patients with patellofemoral dysfunction aim to
recruit the vastus medialis obliquus muscle (VMO) in an attempt to reduce pain and to …

Purpose Motor unit activity is coordinated between many synergistic muscle pairs but the
functional role of this coordination for the motor output is unclear. The purpose of this study …

The purpose of our study was to identify the low-dimensional latent components, defined
hereafter as motor unit modes, underlying the discharge rates of the motor units in two knee …

The present study aimed to investigate the effects of selective fatigue (ie, one muscle of the
quadriceps) on load sharing strategies during submaximal knee extensions. Shear wave …

Single motor unit electromyographic (EMG) activity of the knee extensors was investigated at
different knee angles with subjects (n= 10) exerting the same absolute submaximal isometric …

Architectural differences along vastus medialis (VM) and between VM and vastus lateralis
(VL) are considered functionally important for the patellar tracking, knee joint stability and …

OBJECTIVE: The objective of this work was to study modifications in motor control through
surface electromyographic (sEMG) activity during a very short all-out cycling exercise …

chain tasks. Arch Phys Med Rehabil 2005; 86: 716–21. OBJECTIVES: To investigate motor …

We investigated changes in motor unit (MU) behavior and vasti-muscle contractile properties
during sustained submaximal fatiguing contractions with a new time-domain tracking …
