D) Perform a straight leg raise and dorsiflex the foot

Answer 1

To tension the sural nerve in SLR test, perform a straight leg raise and dorsiflex the foot.

Step-by-step explanation:

In the Straight Leg Raise (SLR) test, the sural nerve can be tensioned by performing a straight leg raise and dorsiflexing the foot. Dorsiflexion refers to pulling the toes towards the shin. By combining the straight leg raise with dorsiflexion, tension is applied to the sural nerve that runs along the back of the leg and foot.
