PTAP 1400 EXAM #3 QUESTIONS WITH VERIFIED ANSWERS LATEST UPDATE 2026
Patella is a fulcrum for - Answers quadriceps when active
Joint Capsule - closed pack positioning hip - Answers internal rotation and extension
Internal rotation takes _____ out of hip - Answers slack
Closed pack position of the hip is - Answers extension with some medial rotation and ABduction -
maximally congruent
Gait cycle - leg swing in air - Answers hamstrings are decelerators into knee extension before foot hits
ground
Function of gluteus medius - Answers hip ABduction
Gluteus medius at hip joint - Answers ABducts and medially rotates the femur
Gluteus medius at pelvis - Answers holds pelvis secure over the stance leg, preventing pelvic drop
Trendelenburg sign - Answers the pelvis drops on the side opposite of stance leg
Gluteus medius gait - Answers when you're walking and every time you swing your leg the pelvis
drops to that side; means there is weakness to the opposite side of the gluteus medius
Lurching gait - Answers if limp is severe, compensatory bending to the problematic side to balance
the center of gravity
Lateral trunk lurch with gait - Answers laterally flexing trunk when taking a step, whichever side is
lurching is the weaker side
Innervation for gluteus medius - Answers Superior gluteal nerve
What is the origin of the muscle that flexes the hip in an open chain and increases lumbar lordosis
when the femur is fixed in a closed chain? - Answers T 12 - L 5 vertebrae
Lumbar lordosis - Answers inward curve of spine
What motions are associated with the muscles that are distally attached to the tibial tuberosity? -
Answers Knee flexion and hip extension
Normal ROM for the tibial femoral flexion in a healthy active male - Answers 135 degrees
What's the common compensation for excessive femoral anteversion? - Answers "in-toeing"
pT stands on right leg and reaches with left arm to the right in the right transverse plane, what motion
is occuring in the right hip? - Answers Internal rotation of the hip
What muscle is known for compression of the sciatic nerve? - Answers Piriformis
Coxa Vara - Answers Inclination that is significantly less than 125 degrees
Coxa Valga - Answers Inclination that is significantly greater than 125 degrees
Torsion Angle - Answers Is the twist between the shaft and neck of the femur
Normal degree of the femoral neck of projecting it upwards - Answers 15 degrees
Excessive anteversion degree - Answers 35 degrees
Retroversion degree - Answers less than 5 degrees
Normal anteversion degree - Answers 15 degrees
Screw-home mechanism - Answers a locking mechanism of the knee created as the joint externally
rotates slightly in conjunction with full extension
What muscle initiates when unlocking the knee? - Answers Popliteus
Popliteus is proximal to...? - Answers The medial head of the Gastroc.
Osteotomy - Answers Surgical cutting or removal of bone
If had a greater trochanteric osteotomy, what motion would be avoided post-op? - Answers
ABduction
Thomas Test is...? - Answers used to rule out hip flexion contracture and psoas syndrome
Positive Thomas Test indicates - Answers pT is unable to maintain their lower back and sacrum
against the table
Overtest is utilized for...? - Answers Tight IT band - ABductors
True or False
If you had tight hamstrings, you would have posterior tilted pelvis in long-sit - Answers True
Patellofemoral Syndrome - Answers potential for weakness or atrophy at the VMO, potential for
tightness of the VA - result in lateral tracking of the patella
lateral retinaculum - Answers connective tissue, apart of IT band
Q-angle - Answers clinical measurement that quantifies the overall line of force of the quadriceps
muscle relative to the patellar tendon
How to measure Q-angle - Answers dropping a plumb-line through the tibial tubercle and middle of
the patella and another from the ASIS to intersect with the first line at the mid-patella
