Q: The Hip-drop test assesses the [...] ability of the lumbar spine and thoracolumbar junction.
A: sidebending
Q: What test is being described? With the patient standing they are instructed to bend one knee without lifting the heel from the floor.
[...]
A: Hip-Drop Test
Q: What indicates a positive Hip-drop Test?
[...]
A: Drop of the iliac crest
Comment 3: Under normal mechanics the lumbar spine sidebends away from the bent knee, creating a convexity on that same side. The iliac crest on the bent-knee side should drop at least 20-25 degrees.

Bone Wizardry Lock: Hip-drop tests lumbar sidebending by having the patient bend one knee in stance. A drop of 20-25 degrees or more on the bent-knee side is normal. Restriction points to somatic dysfunction or paraspinal tightness at the lumbar or thoracolumbar junction.

Q: The Straight Leg Raising Test (Lasegue's Test) is used in the evaluation of [...] nerve compression.
A: sciatic
Q: What test is being described? With the patient supine, the physician grasps the leg being tested under the heel with the hand, and to keep the knee extended, places the other hand on the anterior aspect of the knee. The physician then lifts the leg upward, flexing the hip.

A: Straight leg raising test (Lasegue's Test)
Q: What indicates a positive straight leg raising test?
[...]
A: Pain
Comment 2: Normally, the leg can be raised to about 70-80° of hip flexion.
Comment 3: Once the patient feels pain, the physician lowers the leg just beyond where the pain was felt, and dorsiflexes the foot (Braggard's Test). This stretches the sciatic nerve. If no pain is elicited here, the pain from the leg-raising is probably from tight hamstrings and the test is considered negative.

Bone Wizardry Lock: SLR tensions the sciatic nerve root by stretching it over a herniated disc or narrowed foramen. Braggard's sign separates true radiculopathy from hamstring tightness. Pain reproducing before 70 degrees is the clinically meaningful cutoff.
