Positive sign is any kind of sciatic pain (radiating, sharp, shooting pain) or reproduction of other neurological symptoms. This indicates impingement of the sciatic nerve, dural lining, spinal cord, or nerve roots. [1] This test can have a lot of false-positives and should be used with other orthopedic test to make the final diagnosis.
While this test is positive in about 90% of people with sciatica, approximately 75% of people with a positive test do not have sciatica. [4] Straight leg raising of the leg unaffected by sciatica may produce sciatica in the leg on the affected side; this is known as the Fajersztajn sign. [15]
The straight leg raise is a test that can be performed during a physical examination, with the leg being lifted actively by the patient or passively by the clinician. If the straight leg raise is done actively by the patient, it is a test of functional leg strength, particularly the rectus femoris element of the quadriceps (checking both hip flexion and knee extension strength simultaneously).
Gaenslen's test, also known as Gaenslen's maneuver, is a medical test used to detect musculoskeletal abnormalities and primary-chronic inflammation of the lumbar vertebrae and sacroiliac joint.

For the trial, 216 individuals with chronic sciatica resulting from a herniated disc were treated either with 10 sessions of acupuncture or 10 sessions of sham acupuncture over a period of 4 weeks.
In the context of a positive Hoover's sign, functional weakness (or "conversion disorder") is much more likely than malingering or factitious disorder. [3] Strong hip muscles can make the test difficult to interpret. [4] Efforts have been made to use the theory behind the sign to report a quantitative result. [5]
The Achilles reflex checks if the S 1 and S 2 [3] nerve roots are intact and could be indicative of sciatic nerve pathology. It is classically delayed in hypothyroidism. This reflex is usually absent in disk herniations at the L 5 —S 1 level. A reduction in the ankle jerk reflex may also be indicative of peripheral neuropathy.
