All are possible during contraction of Tensor fasciae latae except
**Core Concept**
Tensor fasciae latae is a muscle in the anterior thigh that plays a crucial role in hip flexion, abduction, and external rotation. The muscle's contraction can lead to various movements and effects on surrounding structures.
**Why the Correct Answer is Right**
During contraction of the tensor fasciae latae, the muscle shortens and pulls on the iliotibial tract, which can lead to several consequences. The muscle's contraction can cause external rotation of the hip, which is a key function of the tensor fasciae latae. Additionally, the tensor fasciae latae can help stabilize the knee and assist in hip abduction. However, the muscle's contraction is not typically associated with hip extension, as this movement is primarily facilitated by the gluteus maximus.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because tensor fasciae latae contraction is associated with hip flexion, not hip extension.
**Option B:** This option is incorrect because tensor fasciae latae contraction can lead to external rotation of the hip, not internal rotation.
**Option C:** This option is incorrect because tensor fasciae latae contraction can assist in hip abduction, not adduction.
**Clinical Pearl / High-Yield Fact**
The tensor fasciae latae muscle is often palpated in a lateral thigh, and its contraction can be assessed through the iliotibial tract, which runs from the iliac crest to the lateral aspect of the tibia.
**Correct Answer: A. Hip extension.**
