What is the primary purpose of the Thomas Test?

• A. Assess hip joint stability
• B. Evaluate knee ligament integrity
• C. Determine hip flexor tightness
• D. Test for nerve compression in the leg

Answer: (C)

The Thomas Test is specifically designed to assess hip flexor tightness. During the test, the patient is instructed to lie supine on an examination table. One hip is brought into flexion with the knee held toward the chest, while the other leg remains extended. Observing the extended leg is key; if it rises off the table, this indicates tightness in the hip flexors of that leg.

The test is valuable in a clinical setting for identifying issues related to muscle imbalances or tightness that can lead to discomfort or functional limitations. When a practitioner finds positive results in this test, it can guide further assessment or interventions tailored to address the specific tightness identified in the hip flexor muscles.

Other options do not align with the primary focus of the Thomas Test. Assessing hip joint stability, evaluating knee ligament integrity, or testing for nerve compression do not pertain to this particular evaluation, which specifically focuses on the flexibility and condition of the hip flexors.
