Final answer:
The seated spinal rotation test is used to assess the range of motion and flexibility of the spine.
Step-by-step explanation:
The seated spinal rotation test is a test used to assess the range of motion and flexibility of the spine. In this test, the individual sits down with their legs extended in front of them and rotates their torso to each side. The distance that the individual is able to rotate indicates the flexibility of their spinal muscles and joints. This test can be used to identify any restrictions or imbalances in the spine that may affect posture and movement.
