What physical evaluation method is useful for assessing tensor fascia latae tightness?

The choice of the Ober test as the method for assessing tensor fascia latae tightness is appropriate because this test specifically evaluates the flexibility of the iliotibial band and the tensor fascia latae muscle. During the Ober test, the patient lies on their side while the examiner stabilizes the pelvis and allows the leg to drop towards the table. If the leg does not fall parallel to the table and remains elevated, it indicates tightness in the tensor fascia latae or the iliotibial band.

This physical evaluation focuses directly on the structures associated with hip abduction and flexion, making it the ideal choice for assessing tightness in the tensor fascia latae. The other tests listed focus on different anatomical structures or functions. For example, the patellar tap test assesses fluid in the knee joint, the Thompson test evaluates the integrity of the Achilles tendon, and the McMurray test is used for diagnosing meniscal tears in the knee. Each of these tests serves a distinct purpose that does not relate to the assessment of the tensor fascia latae, thereby emphasizing the relevance and specificity of the Ober test for this particular evaluation.
