  1. Triggerpoints in de brede zijspier (Vastus Lateralis) kunnen erg vervelend en erg pijnlijk zijn. Vooral sporters die aan sport doen waarbij een langdurig uithoudingsvermogen gevraagd wordt, zijn gevoelig voor deze klachten. Klachten rondom de knie en heup kunnen zorgen voor slijmbeursontstekingen en chronische peesletsels
  2. The Vastus Lateralis supports the action of knee extension, hence it is a muscle that is highly utilised every day as it is essential for walking and standing up. The Vastus Lateralis also protects the knee from flexion. When the Vastus Lateralis is tight you will feel pain in the lower back or knee
  3. Avulsion of the Vastus Lateralis Tendon From Doing Gym Squats A rupture can in principle occur to all muscles in the thigh, however, ruptures most often happen in the anterior muscle (M quadriceps femoris) which has the function of stretching the knee and flexing the hip. The anterior thigh muscle consists of four muscles (M [

  3. The vastus lateralis is a muscle located on the lateral, or outside, part of your thigh. The muscle is one of the four quadriceps muscles and is the largest muscle of that group. The vastus laterails works with the other quad muscles to help extend your knee joint. It also is active in maintaining thigh and kneecap position while walking and running
  4. Stretching the vastus lateralis muscle regularly is a great way to counteract tightness. Apart from stretching, trigger point therapy or myofascial release of the vastus lateralis can help to reduce pain. By using trigger point pressure on the tight/painful spots on the muscle you can alleviate pain and tension
  5. While much research has centred around the relationship between vastus medialis and anterior knee pain, little is known about the most lateral of the quadriceps muscle group, vastus lateralis (VL). Knowledge of the anatomical organization of VL is not only necessary to understand its precise function, but to also assist in the development of clinical and biomechanical models of knee dysfunction
  6. De quadriceps kan een flinke spiermassa vormen. Dit is bijvoorbeeld het geval bij goed getrainde wielrenners, voetballers en schaatsers.

The proximal part of rectus femoris muscle lies deep to tensor fasciae latae, sartorius and iliacus muscles.All the contents of the anterior compartment of the thigh lie deep to rectus femoris. These include the capsule of the hip joint, vastus intermedius, anterior margins of vastus lateralis and vastus intermedius, lateral circumflex femoral artery and some branches of the femoral nerve Vastus Lateralis. Each of the three vastus muscles are located at different spots in the anterior compartment of the upper leg. Each of the muscles are also named for that exact location In all patients, the vastus lateralis shift was selected as reconstructive procedure for the treatment of documented abductor insufficiency. In the past, our group has presented this technique in detail 14, 15.In brief, through a lateral incision, extending from above the greater trochanter to the lateral patellar margin, the iliotibial band was incised in line, and the entire vastus lateralis.

The vastus lateralis muscle is located on the lateral side of the thigh. This muscle is the largest of the quadriceps which includes: rectus femoris, vastus intermedius, and vastus medialis. Together, the quadriceps act on the knee and hip to promote movement as well as strength and stability. They provide power for and absorb the impact of daily activities such as walking, running, and jumping Rectus femoris tendinopathie.

The vastus lateralis is the largest part of the quadriceps femoris. It rises from a broad aponeurosis tendon, which covers the upper three-quarters of the muscle Vastus Lateralis Trigger Point Release. So if you have tight ITBs that you like to roll out, you're really just rolling out the trigger points in your vastus lateralis muscle. What's a trigger point? This is an area in the muscle that doesn't work well and is tight. It's usually caused by irritated nerves in your back The vastus lateralis is used when extending the leg. Any movement that requires extension of the knee will invoke the vastus lateralis muscle. For example, walking up or down stairs will require the muscle in order to avoid excessive mobility in the knee joint. Exercises such as cycling also require the vastus lateralis to be strong

The vastus lateralis (/ ˈ v æ s t ə s ˌ l æ t ə ˈ r eɪ l ɪ s, ˈ r æ-/), also called the ''vastus externus'' [citation needed] is the largest and most powerful part of the quadriceps femoris, a muscle in the thigh.Together with other muscles of the quadriceps group, it serves to extend the knee joint, moving the lower leg forward. It arises from a series of flat, broad tendons.

Vastus lateralis is supplied by the muscular branches of the femoral nerve. runs behind inguinal ligament and into the thigh where it splits into an anterior and posterior division. Vastus lateralis is primarily supplied by lateral circumflex artery, a branch of femoral artery. Vastus lateralis lies in the anterior compartment of the thigh The vastus lateralis is responsible for knee extension. The vastus lateralis does not cross the hip, therefore it does not cause hip flexion, unlike the rectus femoris muscle. The descending branch of the lateral femoral circumflex artery runs between the vastus lateralis and the vastus intermedius muscles. Posteromedial to the vastus lateralis. Aim: This study investigated the force-velocity characteristics of the vastus lateralis (VL) muscle fascicle and muscle-tendon unit (MTU) in isolated lengthening and shortening actions, and during natural movement.

Vastus lateralis (VL) is generally considered to cause the patella to move laterally, and vastus medialis, especially vastus medialis oblique (VMO), pulls the patella medially. The fibers of the VMO are angled 50-55° (with respect to the shaft of the femur), which is almost horizontal, and therefore the VMO is considered the primary medial stabilizer of the patella and has little function.
