Sharply dissect the quadriceps fascia off the vastus lateralis
muscle laterally to its inclusion with the iliotibial band.
In relation to the vastus lateralis
, there was no significant difference in neuromuscular demand between BHT and squat exercises (Contreras et al., 2015).
Comparison of vastus medialis obliquus: vastus lateralis
muscle integrated electromyographic ratios between healthy subjects and patients with patellofemoral pain.
Variability and reliability of the vastus lateralis
The medial lip gives origin to vastus medialis and lateral lip gives origin to vastus lateralis
. Adductor brevis is attached to the proximal part of linea aspera.
There was marked wasting of the left vastus lateralis
and the gastrocnemius muscles and mild wasting of the left biceps and triceps muscles.
The involvement of the vasti muscles (vastus lateralis
, vastus intermedius, and vastus medialis), while sparing the rectus femoris, was remarkable.
Within-day EMG testing has excellent reliability (intraclass correlation coefficient (ICC) 0.91) in contrast to between-day reliability, which showed to have lower reliability (ICC 0.70) for vastus lateralis
and VMO (Worrell et al., 1998).
Bipolar EMG was used to determine muscle electrical activity of the vastus lateralis
(VL), vastus medialis (VM), rectus femoris (RF), and biceps femoris (BF) during isometric contractions.
Muscle architecture of the vastus lateralis
(midway between the lateral condyle and greater trochanter of the femur) was determined using B-mode ultrasound as described previously (12).
Participants underwent vastus lateralis
A longitudinal incision was made along the lateral aspect of the thigh, and an internervous plane was created bluntly between the vastus lateralis
and biceps femoris to expose the anterolateral aspect of the femur (Figure 1(a)).
