Sport Inj Lab Test 1

Question 1

Name the ankle tests/what structures they examine

Answer 1

ATFL stress test
PTFL and CFL stress test

Question 2

Describe the protocol for an ATFL stress test

Answer 2

• ankle is plantarflexed
• grab and stretch so bottom of foot faces medially (inversion)

Question 3

Describe the protocol for the PTFL + CFL stress test

Answer 3

• ankle is dorsiflexed
• grab and stretch so bottom of foot faces medially (inversion)

Question 4

Describe the protocol for a hamstring test

Answer 4

• person lying on front
• ask for permission to put hand on sacrum
• knee bent 90 degrees with ankle twisted medially/laterally
• straighten arm and put hand on lateral side/thumb on medial side of ankle/lower leg
• push against leg and have patient actively resist with hamstrings
• SLOWLY ramp up and down, ideally shouldn’t look like you’re moving it

Question 5

How does the way the ankle is facing translate to the hamstring being tested?

Answer 5

SAME SIDE
Medial ham test: ankle twisted medially
Lateral ham test: ankle twisted laterally

Question 6

Describe the protocol for the FADIR test

Answer 6

• grab the lower leg while person is lying on their back
• flex, adduct and rotate hip internally (pull foot outward

Question 7

What test checks the menisci?

Answer 7

McMurray’s

Question 8

Describe the protocol for McMurray’s test

Answer 8

• the “rainbow” test hehe
• manhandle the upper leg, grab it, bring it to flexion of hip while applying pressure so that lower leg is compressed
• shift weight from one foot to another to create “rainbow”

HEEL POINTS TOWARD “side” we are testing Medial meniscus test = ankle twisted laterally
Lateral meniscus test = ankle twisted medially

Question 9

How does the ankle positioning affect the meniscus tested in McMurray’s?

Answer 9

HEEL POINTS TOWARD “side” we are testing Medial meniscus test = ankle twisted laterally
Lateral meniscus test = ankle twisted medially

Question 10

Which test examines the structural integrity of the ACL?

Answer 10

Lachman’s

Question 11

Describe the protocol for the Lachman’s test

Answer 11

• squeeze lower leg between thighs to stabilize
• distal hand is medial on leg, proximal is lateral on thigh
• pulling tibia forward relative to femur
• evaluates anterior translation of the tibia relative to femur to see structural integrity of ACL

Question 12

What test examines the structural integrity of the PCL?

Answer 12

• posterior drawer

Question 13

Describe the protocol for the posterior drawer test

Answer 13

• patient lying on back, foot in bed and knee bent
• sit on foot of patient
• hand in front of knee, either thumbs in the middle or use palms of hand - trying to push tibia backward relative to femur in an explosive movement

POSITIVE = translates more than 6mm or has soft/mushy end feel, should feel tight resistance

Question 14

What test assesses the structural integrity of the MCL?

Answer 14

valgus stress test

Question 15

What test assesses the structural integrity of the LCL?

Answer 15

varus stress test

Question 16

Describe the protocol for the valgus stress test

Answer 16

• can do either with leg hanging down or laying down with less than 90 degrees flexion
• upper hand on thigh
• bottom hand close to knee
• pull thigh in the opposite direction that it naturally wants to rotate to prevent hip rotation
• pulls bottom leg out to side

Question 17

Describe the protocol for the varus stress test

Answer 17

• sit down in between legs to make it easier
• same as valgus but internally rotate leg
  *make sure to stabilize thigh to prevent hip movement!
