How do you assess popliteus?
To test the popliteus, the patient can be placed on his back on the table with the knee in a 90 degree flexion and the foot in dorsiflexion. To test the popliteus, the therapist then has to going push the foot and underleg externally while the patient has to maintain his position.
What does a popliteus injury feel like?
Popliteus Strain and/or Tendinopathy Symptoms Pain is usually worse when walking downhill, with stairs and when running. The area behind the knee is often swollen and tender to the touch, and there may be a crackling sound with movement if the tendon is involved.
What is the main function of popliteus muscle?
Despite its small size, the popliteus is a major stabilizer of the knee. The popliteus is involved in both the closed chain phase and open-chain phase of the gait cycle. During the closed chain phase, which is when the foot is in contact with the ground, the muscle externally rotates the femur on the tibia.
What are the peculiarities of popliteus muscle?
The popliteus muscle is a thin, flat, triangular-shaped muscle located at the back of the knee joint. This muscle receives electrical impulses from the brain through the tibial nerve and it receives its blood supply from the heart through the popliteal artery.
What causes a tight popliteus muscle?
It can occur following a road traffic accident or a fall when the knee is straightened prior to impact. Overusing the popliteus muscle may also result in a strain injury. Because the knee joint is a complex joint an injury to another structure can also cause an injury the popliteus muscle.
What movement does the Popliteus muscle perform?
| Popliteus muscle | |
|---|---|
| Nerve | Tibial nerve |
| Actions | Medially rotates tibia on the femur if the femur is fixed (sitting down) or laterally rotates femur on the tibia if tibia is fixed (standing up), unlocks the knee to allow flexion (bending), helps to prevent the forward dislocation of the femur while crouching |

What are the different types of musculoskeletal assessments in nursing?
During a routine assessment of a patient during inpatient care, a registered nurse typically completes the following musculoskeletal assessments: 1 Assess gait 2 Inspect the spine 3 Observe range of motion of joints 4 Inspect muscles and extremities for size and symmetry 5 Assess muscle strength 6 Palpate extremities for tenderness [2]
What are the 3 origins of the popliteus muscle?
It has 3 origins: the lateral femoral condyle, the fibular head, and the lateral meniscus. The proximal insertion of the popliteus muscle is on the proximal side of the tibia, proximal of the linea muscli solei. The insertion on the lateral meniscus is absent in 82,5% of cases.
