The Goldthwait's test aims to determine dysfunction in which anatomical region?

The Goldthwait's test is specifically designed to assess dysfunction in the sacroiliac joint. During this test, the examiner palpates the lumbar spine while passively elevating the leg, which helps to differentiate between issues originating from the lumbar spine and those from the sacroiliac joint. If pain is elicited in the sacroiliac region when the leg is raised with the lumbar spine relaxed, it suggests that the sacroiliac joint may be the source of dysfunction. Thus, this test is particularly useful in evaluating conditions that could lead to painful symptoms in the pelvic region or lower back and helps guide the physical therapist in diagnosing and developing an appropriate treatment plan.
