Although prone "functional leg length" is a widely used chiropractic tool, it is not a recognized anthropometric technique, since legs are often naturally of unequal length, and measurements in the prone position are not entirely valid estimates of standing X-ray differences. [10] Measurements in the standing position are far more reliable. [11]

Although prone "functional leg length" is a widely used chiropractic tool in their Activator technique, it is not a recognized anthropometric technique, since most legs are usually only to a small degree unequal, and measurements in the prone position are not entirely valid estimates of standing X-ray differences.

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).
A chiropractic adjustment intends to affect or correct a vertebral joint's alignment, motion, and/or function. Specifically, adjustments are intended to correct "vertebral subluxations", a non-scientific term given to the signs and symptoms that are said by chiropractors to result from abnormal alignment of vertebrae.

Involuntary extension of the "normal" leg occurs when flexing the contralateral leg against resistance. To perform the test, the examiner should hold one hand under the heel of the "normal" limb and ask the patient to flex the contralateral hip against resistance (while the patient is supine), asking the patient to keep the weak leg straight while raising it.
Some chiropractic schools offer post-professional degrees in chiropractic specialisms, such as veterinary and rehabilitative chiropractic. In the United States, it is possible to receive board certification in a chiropractic specialism. Board certified chiropractics receive a diploma in the specialism and are known as a diplomate or fellow.
Some stretches to help prevent injury to the posterior cruciate ligament include stretching of the hamstring muscles by extending the legs, toes pointing up, leaning forward until the stretch is felt and holding for a few seconds. Exercises that strengthen the knee joints and the hamstrings include prone knee flexion.
