Which part of the body shows symptom changes in the tension/bowstring test?

The tension/bowstring test is specifically designed to assess the integrity of the sciatic nerve and its branches by evaluating the neurodynamic mobility of the structures that traverse the lumbar spine down to the lower limbs. This test typically focuses on the area behind the knee, also known as the popliteal fossa, where nerves, blood vessels, and tendons converge. When the tension/bowstring test is performed, any changes in symptoms such as pain or discomfort indicate issues with the nerve's mobility or entrapment along its path. This makes the popliteal fossa the primary area where significant symptom changes are expected during the test, confirming that it is the correct answer. Other locations such as the hip, knee, and foot are not the primary focus of the tension/bowstring test, as the test directly relates to the neurodynamic assessment of the structures behind the knee.
