Which of the following is the primary method used during a scoliosis screening to detect abnormal spinal curvature?

Choice A rationale Phalen's Maneuver is a diagnostic test used to assess for carpal tunnel syndrome. It involves sustained wrist flexion, which increases pressure within the carpal tunnel, exacerbating median nerve compression symptoms such as tingling and numbness in the hand. This test is unrelated to spinal curvature assessment. Choice B rationale The Romberg Test evaluates proprioception and cerebellar function, assessing a person's ability to maintain balance with eyes closed. It helps identify neurological deficits affecting balance and coordination but does not involve direct assessment of spinal alignment or curvature, thus it is not used for scoliosis screening. Choice C rationale Adam's Forward Bend Test is the primary method used during scoliosis screening. It involves the individual bending forward at the waist with feet together and arms hanging loosely. This position makes any asymmetry or prominence of the ribs or spine more visible, indicating a potential spinal curvature. Choice D rationale Lasegue's Sign Test, also known as the Straight Leg Raise Test, is used to detect nerve root irritation, typically associated with sciatica or herniated lumbar discs. It involves passively raising the straightened leg of a supine patient to elicit pain, indicating nerve compression. This test is not for scoliosis screening.
