Which term describes pain experienced during right hip extension?

1. Psoas's

2. Obturator's

3. Iliopsoas

4. Gluteus maximus

The correct answer is: Psoas's

The term that describes pain experienced during right hip extension is associated with the involvement of the iliopsoas muscle, particularly when the hip is actively extended against resistance or when the hip is in a position that places stress on the muscle. The iliopsoas is a key hip flexor composed of the iliacus and psoas major muscles, and while the primary function is hip flexion, issues related to the psoas often lead to discomfort or referred pain in the hip region particularly when the hip is extended. When the hip is extended, it can place tension on the iliopsoas, especially if there is any underlying pathology, such as inflammation or strain. This results in referred pain that may be felt in the lower abdomen, groin, or in the anterior aspect of the hip. On the other hand, while the obturator nerve may play a role in hip sensation and movement, the pain associated with hip extension is not specifically attributed to it. The iliopsoas is central to these movements, and pain related to hip function during extension is more closely tied to its involvement. Gluteus maximus, although a major extensor of the hip, would not be referred to characterize this specific pain when focusing on hip
