What is the VMO muscle?
VMO is short for vastus medialis oblique muscle. It is one of the quadriceps muscles on the inside front of the thigh, just above the knee. Strengthening this muscle is particularly important for knee rehabilitation as it helps control the position of the patella (kneecap). Introduction to VMO strengthening exercises
What is an IT Vendor Management Office (VMO)?
What is an IT Vendor Management Office (VMO)? – BMC Software | Blogs What is an IT Vendor Management Office (VMO)? The vendor management office (VMO) is a business unit within many enterprises that is responsible for evaluating suppliers of goods and services, and overseeing regular interaction and long-term relationships with vendors.
What does VMO mean in aviation?
— Maximum operating limit speed for turboprops or jets. VMO is indicated airspeed measured in knots and is mainly a structural limitation that is the effective speed limit at lower altitudes.
What is vastus medialis oblique (VMO)?
Vastus Medialis Oblique Rehab. VMO stands for vastus medialis oblique and is part of the vastus medialis quadriceps muscle at the front of the thigh. Here we explain why strengthening this muscle is so important for knee rehabilitation.
What does the VMO muscle do?
The portion of the muscle that is just above the knee is sometimes referred to as the vastus medialis obliquus, or VMO. This muscle is used to extend the leg at the knee and to stabilize the patella, which is also known as the kneecap.

What is the VMO in the knee?
When you extend your leg fully, you can feel and sometimes see this muscle contract. That section of the muscle that's just above the kneecap is referred to as the vastus medialis oblique (VMO). Your vastus medialis helps to stabilize your kneecap and keep it in line when you bend your knee.
What happens if VMO is weak?
When the VMO is weak, the other quadriceps muscles pull the knee cap to the outside part of the groove. This can lead to rubbing and excess wear and tear of the joint surfaces in the outside or lateral patellofemoral joint region.
Can a weak VMO cause knee pain?
When patients develop VMO weakness, there is a relatively greater pull to the outside as the lateral portion of the quadriceps overcomes the weaker medial side. This results in a patella that is pulled to the lateral side of its groove, which can ultimately cause pain.
Do squats work VMO?
Although front squats do work the VMO, you can increase the activation of these muscle fibers and improve strength gains. The VMO is more fully activated during the final degrees of knee extension -- concentrate on locking out your knees at the top of the front squat.
What does a torn VMO feel like?
The teardrop-shaped muscle helps move the knee joint and stabilizes the kneecap. Injury to the vastus medialis can cause knee pain and difficulty walking, running, or managing stairs.
Can you tear your VMO?
Injuries to the knee are a common occurrence in sports. Ligament injuries, patellofemoral pain syndromes and meniscal tears can all create autogenic muscle inhibition, and this can shut down the excitability of the quadriceps muscles – particularly the VMO.
Why does my VMO muscle hurt?
The VMO is also commonly overloaded with repeated use in the following situations: suddenly increasing your volume of running or cycling (running places around 6 x body weight through the quads) a new (or sudden increase) in an exercise program involving repetitive squats, lunges, leg extensions or wall sits.
When is the VMO most active?
The VMO is most active in the final 30 degrees of knee extension. Prophylactic bracing does reduce the frequency of injuries to the joint that is being protected in most instances. The patella is used as a pulley by the vasti musculature to generate force and extend the knee.
Do lunges work VMO?
Advanced Vastus Medialis Exercises Once you can do 30 reps of each of these vastus medialis exercises with good control and are feeling confident that you are activating your VMO, you can progress onto more advanced exercises such as lunges, step ups and step downs without needing the ball.

What causes VMO atrophy?
The most common explanation is that the quadriceps atrophy is caused by reflex inhibition leading to loss of muscle contractility and thus muscle size over time7. This phenomenon is commonly referred to as 'autogenic muscle inhibition' or AMI8.
What is the role of the VMO?
The specific role of the VMO is to stabilise the patella within the patella groove and to control the tracking of the patella when the knee is both bent and straight.
How to increase VMO load?
Turn your leg outwards can increase the load on the VMO muscle.
How to get a VMO muscle to contract?
Sit on a chair, or the floor and place your hand on your VMO muscle to palpate (feel) it contracting. Slowly straighten your knee ensuring your VMO muscle on the inside of your thigh contracts. Maintain the contraction throughout the movement as you fully straighten the knee and bend it again. Turn your leg outwards can increase the load on ...
How to get rid of VMO muscle?
Put your fingers over the area of VMO muscle on the inside of the thigh and contract the muscle. The knee should push down into the towel and the leg straightens so that the foot lifts off the couch. You should feel a strong contraction of the muscle under your fingers.
Is my VMO muscle contracting properly?
First, you must ensure that your VMO is contracting properly. Long-term injuries such as Patellofemoral knee pain are often caused by VMO malfunction.
What is VMO?
Vastus Medialis Oblique ( VMO ) is one of four quadriceps muscles. Your VMO sits medially or on the inside of your thigh. Its primary function is to extend the knee. Structure: The VMO is a muscle located in the anterior (front) compartment of the thigh.
What is the difference between VMO and Vne?
At some altitude (the knee altitude), the limit is expressed in Mach so you have Mmo. Vmo =Mmo at the knee altitude.
What is Vmax in aviation?
VMAX: Maximum speed Definition VMAX is the maximum speed defining the aircraft’s flight envelope.
Why does VMO decrease with altitude?
Because EAS decreases with altitude for a given mach number, sonic flow starts to predominate (so Mmo takes over) – because higher altitudes will have lower dynamic pressures (which makes Vmo less critical).
What happens when you exceed MMO?
At some point, the air in front of your wing may be subsonic, but it will accelerate past the speed of sound as it flows over the wing’s upper surface. Once this happens, a shock wave forms.
What is V1 and V2 on takeoff?
It can be said that V1 is the “commit to fly” speed. V2 is the speed at which the airplane will climb in the event of an engine failure. It is known as the takeoff safety speed.
Is VREF same as Vapp?
Vref is the actual touchdown speed at which the wheels should make contact. Vapp is your approach speed, and is adjusted for any wind component you might have. You drop from Vapp to Vref usually by just going idle at a certain point in the flare. Vref is the speed over the threshold, not the touchdown speed.
Vastus Medialis (VMO) Muscle
One of the largest muscle groups in the human body is the quadriceps femoris. The quadriceps femoris is comprised of five different muscle bellies (the widest part of a muscle) formed by four separate, but interrelated, muscles: the rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius.
Vastus Medialis Exercises
There are a variety of exercises that target the vastus medialis and the surrounding muscles of the quadriceps femoris. Some examples of vastus medialis exercises include:
Vastus Medialis Pain
Vastus medialis pain is often associated with injuries of the knee region and surrounding tissues. The pain is typically located at the inner thigh, inner knee, and anterior knee regions.
How to get rid of VMO?
Clenching a squashy ball between your knees as you do vastus medialis exercises really helps to make sure the VMO is switching on. A foam ball is best but if you don’t have one, use a soccer ball, just make sure has a bit of give in it by letting some of the air out.
Which exercise activates the VMO?
Keeping the leg turned outwards in this vastus medialis exercise again helps to activate the VMO
How does VMO help with patella dislocation?
This would place excessive friction through the cartilage lining the back of the kneecap as well as increasing the risk of patella dislocation. However, the positioning and direction of the VMO muscle fibres help to counteract this by drawing the kneecap inwards, or medially.
What is the VMO in the thigh?
Associated Conditions. Rehabilitation. The vastus medialis (vastus medialis oblique, or VMO) is one of the four quadriceps muscles in the front of your upper thigh. The teardrop-shaped muscle helps move the knee joint and stabilizes the kneecap.
Can a VMO cause weakness?
VMO weakness after surgery or injury. If you have knee surgery, there will likely be swelling around your knee joint. The swelling can irritate the nerves that supply the muscles (including the vastus medialis) leading to weakness. These symptoms usually improve as the swelling gets better and the injury heals.
What is the difference between VMO and MMO?
MMO is a percentage of Mach limited by the change to the aircraft’s handling characteristics as localized airflow approaches the speed of sound, creating shock waves that can alter controllability. As altitude increases, indicated airspeed decreases while Mach remains constant. MMO is the effective speed limit (“barber pole” on the airspeed indicator) at higher altitudes. MMO is usually much higher for swept-wing jets than for straight-wing designs.
What is VMC in aircraft?
— More commonly known as VMC (although VMCA is more correct). Minimum control speed with the critical engine (usually the left) inoperative out of ground effect in the air — “red line” — and most critical engine inop and windmilling; 5 degrees of bank toward the operative engine; takeoff power on operative engine; gear up; flaps up; and most rearward CG. In this configuration, if airspeed is allowed to diminish below VMC, even full rudder cannot prevent a yaw toward the dead engine. At slower speeds, the slower-moving wing — the one with the failed engine — will stall first. VMC is not a constant; it can be reduced by feathering the prop, moving the CG forward and reducing power.
What is V1 in airplanes?
V1 also means the minimum speed in the takeoff, following a failure of the critical engine at VEF , at which the pilot can continue the takeoff and achieve the required height above the surface within the takeoff distance.
What does VS1 mean?
— Stall speed or minimum steady flight speed in a specific configuration. Normally regarded as the “clean” — gear and flaps up — stall speed. Lower limit of the green arc (remember, “stuff in”). However, this is not always the case. It could represent stall speed with flaps in takeoff position or any number of different configurations. So VS1 is a clean stall, but the definition of “clean” could vary.

Signs and symptoms
Diagnosis
- A thorough biomechanical assessment is required in order to progress with a treatment plan. The first step is to correct any over-pronation at the feet using orthotics.
Treatment
- There is no manipulation or adjustment (such as you might receive at a chiropractor) to reduce Q angle. Correct biomechanics must be achieved through a rehabilitation program which focuses on restoring flexibility to tight muscles (commonly calves, hamstrings, and quadriceps. If the muscle does not contract, continue to practice whilst pressing down gently on the muscle and concentr…
Structure
- The position of the vastus medialis oblique is just above and to the inside of the kneecap. The fibres of VMO have a more oblique alignment than the other fibres of vastus medialis. It arises from the tendon of adductor magnus muscle and converges to join the other quadriceps muscles inserting via the patella tendon, to the tibial tuberosity at the top of the tibia shin bone.
Clinical significance
- VMO is important in keeping the kneecap tracking correctly. It is an active and dynamic stabiliser of the patella. In healthy, pain-free individuals the fibers of the VMO are active throughout the range of movement. In patients with patellofemoral knee pain or chondromalacia patella the fibres contract in phases inconsistently and fatigue easily.
Function
- The specific role of VMO is to stabilise the patella within the patella groove and to control the tracking of the patella when the knee is bent and straightened. Mis-firing and weaknesses in the VMO cause mal-tracking of the patella and subsequent damage to surrounding structures and aching pain.
Prevention
- Sitting on a chair palpate or feel the VMO muscle. Start to slowly straighten the knee and ensure the VMO contracts. Maintain the contraction throughout the movement as you fully straighten the knee and bend it again. Repeat this twice daily until you can maintain a strong constant contraction 10 times in a row Once you can hold the contraction as above, start to integrate this …
Performance
- For the lunge, with a split stance initially place one or two fingers on the VMO of the front leg. Perform a lunge by bending the front knee and dropping the back knee towards the floor. Maintain VMO contraction throughout the lunge. Initially perform as many as you can while maintaining a strong constant contraction and gradually increase the number up to 20.
