Elite dancers have a higher rate of injury than college athletes. This may be due, in part, to
improper alignment during dance movements. Electromyography (EMG) can be an …

Disagreement exists as to whether the individual components of the quadriceps femoris can
be preferentially activated, ie., that one muscle component is activated to a greater degree of …

Patellofemoral joint deterioration (PFJD) is frequently seen in physical therapy clinics and
represents a significant problem for both patients and rehabilitation clinicians. The vastus …

Imbalances in the tiring pattern and contraction intensity of the vastus medialis oblique
(VMO) and the vastus lateralis (VL) have been considered important factors contributing to …

Objective: To determine 1) the electromyographic (EMG) reliability within and between
testing sessions; 2) the effect of sex on the EMG activity of the vastus medialis oblique …

Objective: To compare average electromyogram (EMG) activity of the vastus medialis
obliquus (VMO) and vastus lateralis (VL) during straight-leg raise (SLR) and knee extension …

Context: One factor believed to affect Patella tracking is an alteration in the timing of the
contraction of the muscular stabilizers of the patella. The muscles responsible for this are …

Background and Purpose. The purpose of this pilot study was to see if there was a difference
in amount of electromyographic (EMG) activity in the quadriceps (vastus medialis and vastus …

Weightlifting shoes (WL) are almost universally used by weightlifters, yet are not nearly as
common in weightrooms, where running/athletic shoes (RS) are more common. While some …
