quad·ri·ceps fem·o·ris mus·cle

(kwahd'ri-seps fem'ŏr-is mŭs'ĕl)
Origin, by four heads: rectus femoris, vastus lateralis, vastus intermedius, and vastus medialis; insertion, patella, and thence by ligamentum patellae to tuberosity of tibia; action, extends leg; flexes thigh by action of rectus femoris; nerve supply, femoral.
Synonym(s): musculus quadriceps femoris [TA] , quadriceps muscle of thigh.

Conclusion: The results obtained from this study show that the two strengthening techniques just used in the study can be used to improve muscle strength, performance and isokinetic parameters in healthy quadriceps femoris muscle (pLess than0.05).
The mobilization of quadriceps femoris muscle and knee joint is executed in 37 patients, arthrolysis and mobilization of the knee joint--in 10, and arthroplasty of knee joint with using allogeneic umbilical cords--in 5 patients.
Additionally, although quadriceps femoris muscle group weakness contributes to fall risk, performing post-TKA appraisal of the strength of this muscle group and its function during stair-climbing can be difficult because of concerns regarding patient pain levels and safety, surgical incision status, and prosthesis integrity.

Accordingly, in this situation, when an athlete can jump as high as possible with maximum weight, quadriceps femoris muscle makes the knee extension and prevents patella in order not to move towards the lateral (Demirel and Kosar, 2002).

The lumbar plexus consists of sensory and motor nerves, which innervates visceral organs in the pelvis and anterior and anterolateral dermatomes of the thigh and the medial dermatome of the lower leg, as well as provides motor control for the quadriceps femoris muscle (8, 9).

Second, [EMG.sub.%MVC] in hamstring muscles were much lower than in the quadriceps femoris muscle. The reported data is relevant to determine the load that vibration imposes on the neuromuscular system.
