Clinical Skills and Approaches 
Ely’s test
Rectus femoris is the only Quadriceps muscle that cross the hip joint and act as a hip flexor and knee extensor. When the rectus femoris is shortened/tightened, it tends to pull the pelvis forward into anterior pelvic tilt and also forces the knee into hyperextension. Ely’s test: Patient is positioned…

Ober’s Test
Tensor fascial latae (TFL) originates from the anterior superior iliac spine (ASIS) outer surface, outer lip of anterior iliac crest and deep surface of fascia latae, continues down in thigh as Iliotibial band (ITB) and inserts to the ipsilateral Gerdy’s tubercle. TFL plays role in flexion, medial rotation and abduction…

Thomas Test and Staheli Test
Thomas test Synonym: Hip flexion contracture test, Iliacus test, Iliopsoas test Fixed flexion deformity of the hip and anterior pelvic tilt leads to a compensatory hyperlordosis of the lumbar spine to restore the body’s center of gravity. Compensatory hyperlordosis can mask the fixed flexion deformity of hip. Thomas test: With…
