Final answer:
Pain during a positive Noble compression test is most likely elicited at an angle of 30 degrees of knee flexion, as this is when the iliotibial band passes over the femoral epicondyle.
Step-by-step explanation:
The angle in degrees of knee flexion that will MOST likely elicit pain during a positive Noble compression test is 30 degrees. This test is used to assess for iliotibial band syndrome where pain is elicited by compression of the tissue over the lateral femoral epicondyle while the knee is flexed and extended. Typically, pain is most noticeable at around 30 degrees because this is the angle at which the iliotibial band passes over the femoral epicondyle.
