Vastus
medialis oblique and vastus lateralis activity during a double-leg semisquat with or without hip adduction in patients with patellofemoral pain syndrome.

INT: intact rats; [SCI.sub.1m]: rats 1 month after spinal cord transection; [SCI.sub.4m]: rats 4 months after spinal cord transection; [SCI.sub.TR]: rats 4 months after spinal cord transection with a graft; TA: tibialis anterior muscle; GM: gastrocnemius muscle; ECM: extensor caudae
medialis muscle.
Proprioceptive acuity predicts muscle co-contraction of the tibialis anterior and gastrocnemius
medialis in older adults' dynamic postural control.
An MRI scan of the right thigh, however, revealed extensive periosteal and bone marrow edema, multilocular small periosteal-based fluid-collections throughout the femoral shaft, and extensive edematous changes in the soft tissues of the thigh, predominantly in the vastus
medialis and biceps femoris muscles (Figure 1).
After shaving and cleaning the skin of the patient with cotton and 70% alcohol, 1 cm disc shaped bipolar surface electrodes (Ag AgCl-1 surface with foam and solid gel) connected to the preamps in center-to-center interelectrode distance of 2 cm (Malek et al., 2006; Espindula et al., 2012) were placed on the following left lower limb muscles: Gluteus Medius, Tensor Fasciae Latae, Rectus Femoris, Vastus
medialis, Vastus lateralis, Biceps Femoris, Tibialis Anterior and Gastrocnemius (Lateral Subdivision), and the reference electrode was placed on the left lateral malleolus.
The BioVision 8 channel sEMG device with sampling frequency of 1000 Hz was used to record the activities of seven leg muscles: tibialis anterior, gastrocnemius, soleus, vastus
medialis, rectus femoris, gluteus maximus, and biceps femoris.

Zielinski considers these symptoms of a psychopathia
medialis, which covers up the complexity of every media-historical situation and event.
Muscle recruitment pattern for vastus
medialis oblique muscle: a systematic review
Repeat as above, with the addition of turning your foot and knee outwards slightly to engage the vastus
medialis (part of the quadricep muscle of the thigh).
[19] Potential contributing factors that have been studied are vastus
medialis oblique insufficiency, decreased quadriceps, hamstrings, and ilitibial band flexibility, femoral anteversion, increased quadriceps angle, and patellar hypermobility.
