Thomas Test - a measure of hip flexor tightness
Patient is supine with both knees comfortably flexed to chest to help flatten lower back to the table. Care should be taken not to forceably flex the legs to the chest as this may cause the patient discomfort and alter the measure. Flattening the low back to the table is done in an effort to achieve a neutral pelvic position. A neutral pelvic position is defined as having the ASIS and PSIS in the same horizontal plane. With the patient supine, a line connecting the ASIS and PSIS should be perpendicular to the exam table. The hip on the side to be measured is passively extended until the pelvis begins to tilt anteriorly. The hip position is measured just prior to the tilting of the
pelvis. The patient should be posioned on the exam table so that the edge of the table does not interfere with extension of the measured limb. The first hip measurement is taken with the ipsilateral knee extended fully. The second hip measure is taken with the ispilateral knee flexed to 90 degrees.

Craig Test - a measure of femoral torsion
The patient is prone with both legs comfortably extended. The knee on the measured side is flexed to 90 degrees. The ipsilateral greater trochanter is palpated between the examiners index finger and thumb as the leg is internally and externally rotated. The most lateral position of the greater trochanter is determined through palpation and the degree of ipsilateral hip internal or external rotation is measured.

Ober Test - a test of Iliotibial Band tightness
The patient is sidelying with the lower leg comfortable flexed to help stabilize the position. The examiner cradles the flexed upper limb with one arm while stabilizing the patients pelvis with their opposite hand. A line connecting the patient's AISIS's should be perpendicular to the exam table. The knee on the measured side should be flexed to 90 degrees and maintained in flexion throughout the test. The hip on the side to be test is passively flexed, abducted and finally extended.  The hip in then slowly lowered toward the table. The test is negative if the knee on the tested side lowers to the exam table.The test is possitive if the leg being tested remains off the exam table.  With a possitive test, he degree of hip ab/adduction on the tested side can be measured to obtain more information about the extent of I T Band tightness. To accurately perform this test the iliotibial band should pass over the ipsilateral greater trochanter during testing. To achieve this the tested hip should be fully extended.

Ely Test - a test of Rectus Femoris tightness
The patient is prone with both legs comfortably extended. The knee on the side to be tested is  passively flexed to 90 degrees while the examiner stabilizes the ipsilateral pelvis. The test is possitive if the hip on the tested side flexes away from the table when the ipsilateral knee is at 90 degrees of flexion. The test is negative if the anterior hip and pelvis remain in contact with the exam table during knee flexion. The knee on the testing side is flexed slowly to overcome any resistance to passive stretch.
