Which of the following compensations is NOT identified during the modified Thomas Test?

The modified Thomas Test is primarily designed to assess hip flexor tightness and other pelvic and hip alignments. When conducting this test, the practitioner observes how the subject's legs behave when the opposite leg is brought to the chest while lying supine.

Hip flexor tightness is identified when the leg hanging down does not drop below the level of the table, indicating that the hip flexors are restricting full extension. Compensatory patterns such as pelvic drop or quadriceps dominance can also be assessed based on how the pelvis shifts and how the muscles around the knee and hip interact during the movement.

However, shortening of the hamstrings is not typically evaluated by this test. The modified Thomas Test specifically focuses on hip flexor behavior and pelvis alignment rather than the length or flexibility of the hamstrings. Therefore, acknowledging that shortening of the hamstrings is not directly observed during this test justifies why it is the option that does not fit within the context of findings typically identified by the test.
