Visual Assessment of Postural Antecedents to Nonspecific Low Back Pain
Published in David Lesondak, Angeli Maun Akey, Fascia, Function, and Medical Applications, 2020
While the vastus intermedius affects the hip through its connection to the iliofemoral ligament, only the rectus femoris crosses the hip to attach to the anterior ilium. Although this position would make the rectus femoris an obvious candidate for maintaining the pelvis in an anterior tilt (hip flexion), the fact that it is a polyarticular muscle makes it a bad candidate to stabilize posture because it would have to simultaneously steady both hip and knee joints to work in this way. Thus, the effect of the lower SFL on NSLBP is indirect.

Video 5.4 Video of single-leg squat on normal right and abnormal left. Note the low-riding patella baja on the left. After this dynamic physical exam, loss of tensional integrity at the vastus intermedius in the thigh was found via dynamic ultrasonography.
Referred Pain and Trigger Point
Published in Hooshang Hooshmand, Chronic Pain, 2018
Injection of the vastus intermedius relieves pain in the quadriceps region. Injection of the gluteus minimus results in relief of pain in the posterior aspect of the thigh and the leg and injection of the gluteus maximus relieves pain in the gluteal fold.

In the present study, the mobility domain of the PEDI declined with decreased vastus lateralis muscle thickness. In the quadriceps femoris muscle, the activity of the vastus lateralis muscle increases from initial contact to loading response during walking.34,35 Furthermore, the physiological cross-sectional area of the vastus lateralis muscle is greatest in the quadriceps femoris muscle.36 The vastus lateralis muscle rather than the rectus femoris and vastus intermedius muscles may contribute to the extension movement of the knee joint in the standing position and during walking because the greater physiological cross-sectional area is advantageous to exert muscle strength. Thus, reduced PEDI mobility domain scores might be associated with decreased vastus lateralis muscle thickness in children and adults with CP as muscle strength of the vastus lateralis muscle is important for mobility such as walking. A previous study demonstrated the association between declined ADL assessed using the mobility area of the BI and decreased thickness of the rectus femoris muscle in children with CP.12 However, the results of the present study revealed the association between declined ADL assessed using the mobility domain of the PEDI and decreased vastus lateralis muscle thickness in children and adults with CP. The inconsistency of these results might be due to differences in age, ADL measurement methods, and statistical analyses between this study (children and adults, PEDI, and stepwise regression analysis) and the previous study (children, BI, and partial correlation analysis).

At the thigh level, former MRI studies on DM1 reached a consensus that the anterior compartment was the most affected region, and the vastus intermedius and medialis muscles were more deteriorated compared to the vastus lateralis muscle, while the rectus femoris was relatively spared [2,13,14]. Our findings confirmed the previous data that the most severely affected muscles in the thighs were usually the vastus medialis and vastus intermedius, followed by vastus lateralis. But to be noted, although the anterior thigh compartment was preferentially degenerated in DM1 patients, the other compartments were also involved as the disease progression. Exceptionally, our data revealed that 1 of the 24 patients showed that the posterior compartment was the most severely affected region in the thighs (Figure 2(k and l)), suggesting that the anterior compartment being the most affected region in the thighs was found in the majority of DM1 patients, but it was not the unique muscle involvement pattern. Regarding the least affected muscles in the thighs, there is no consistent statement entirely. Park et al. [2] reported that the adductor muscles and biceps femoris long head were the least affected in the thighs. Peric et al. [14] revealed that the least affected thigh muscles were the adductor muscles, followed by the rectus femoris, sartorius, biceps femoris long head, and semimembranosus. Hamano et al. [12] revealed that the adductor magnus, biceps femoris long head and gracilis were least affected in the thighs. Our data revealed that the gracilis and rectus femoris were the least affected muscles in the thighs.

The rats were anaesthetized using intraperitoneal administration of pentobarbital sodium (10 mg/kg), 48 h after the single bout running session. Promptly, after confirming breathing and cardiac arrest, blood samples were taken through cardiac puncture, and centrifugalized immediately at 3000 rpm for 10 min at 4 °C for serum separation. Immediately after blood collection, the vastus intermedius (VI) muscles were collected from the hindlimbs of left sides. VI are muscles specifically recruited in uphill and downhill running, respectively (Armstrong, Ogilvie, et al. 1983). The serum samples were stored at −80 °C until use. Paraffin embedding was performed on the left leg muscles, after fixation by 10% phosphate-buffered formalin at 4 °C for 24 h, and then, stored as paraffin blocks.
