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).

However, Lasègue noted that he could tell malingerers apart from patients experiencing real sciatic pain by just conducting the leg raise test. [7] Although Lasègue was the one to emphasize its presence in sciatica and the importance it held for diagnostics, it was his student named Forst in 1881 who first described the sign.
In medicine, Carnett's sign is a finding on clinical examination in which abdominal pain remains unchanged or increases when the muscles of the abdominal wall are tensed. [1] [2] For this part of the abdominal examination, the patient can be asked to lift the head and shoulders from the examination table to tense the abdominal muscles.
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 presence of the Fajersztajn sign is a more specific finding for a herniated disc than Lasègue's sign. [ 15 ]
Distraction tests: positive tests are rechecked when the patient's attention is distracted, such as a straight leg raise test; Regional disturbances: regional weakness or sensory changes which deviate from accepted neuroanatomy; Overreaction: subjective signs regarding the patient's demeanor and reaction to testing
Straight leg raise – Maneuver used to assess for hamstring tightness. The straight leg raise has been found to be positive in only 10% of patients with spondylolisthesis. [26] Muscle strength exercises – Lower abdominal, gluteal, and lumbar extensors should be assessed for weakness.
