Functional Lower Extremity Tests
There are several tests available for assessing the return to play. Six lower extremity functional tests are discussed to assess strength, symmetry, balance, and/or agility.
The “Other” Cruciate Ligament, AKA PCL
The posterior cruciate (PCL) is composed of two bands that blend together. It attaches to the posterior intercondylar area and passes anterosuperiorly to insert into the lateral surface of the medial femoral condyle. The PCL is responsible for posterior translation of the tibia on the femur in open kinetic chain and anterior translation of the femur on the tibia in closed kinetic chain.
Challenges of SI Testing: Part 2
Evaluating the SI Joint can be challenging with very small amounts of movement and tests with variable statistical values.
Challenges of SI Testing: Part 1
The SI joint is stabilized by a network of ligaments and muscles. The normal sacroiliac joint has been shown to have approximately 2-4 mm of movement. So yes, the SIJ does move!
Putting “Special Tests” in Perspective
Assessing the value of "Special Tests" can be a clinical challenge.
