Exam 2

Question 1

When sitting with your foot flat on the floor and simply sliding your forefoot laterally while keeping your heel flat on the ground so only 1 motion occurs, what motion is occuring?

Answer 1

Calcaneal (subtalar) abduction

Question 2

What are the 3 movements of the calcaneus in open chain supination?

Answer 2

plantarflexion, inversion and adduction

Question 3

What are the 3 motions of the calcaneus in open chain pronation?

Answer 3

dorsiflexion, eversion, and abduction

Question 4

What is are the movements of subtalar joint in closed chain pronation?

Answer 4

IR of Tibia and fibula
ADDuction and plantarflexion of talus
Eversion of calcaneus

Question 5

What are the movements of the subtalar joint in closed chain supination?

Answer 5

ER of tibia and fibula
ABDuction and dorsiflexion of talus
Inversion of calcaneus

Question 6

During closed chain pronation, what does the talus do?

Answer 6

Adducts and plantarflexes

Question 7

If someone has increased genu valgum, this is often cause increased tibial internal rotation. What will this most commonly do to the subtalar joint in a closed chain position?

Answer 7

Pronation

Question 8

T or F: A high ankle sprain can involve both the distal tib-fib joint and the interosseus membrane of the middle tib-fib joint.

Answer 8

True!

Question 9

T or F: When it comes to a good athletic position, you should weight bear on the ball of your foot with a partial squat, which results in partial dorsiflexion. This is a better position to prevent ankle sprains vs being too much on toes with plantarflexion.

Answer 9

True

Question 10

T or F: There is a high risk of bony trauma with eversion ankle sprains.

Answer 10

True! Can fracture fibula which will widen the mortice

Question 11

T or F: When we want to have more rigidity in the subtalar joint (like with push off) we want it in supination. Then if we want more mobility or shock absorption we want it in pronation.

Answer 11

True! Supination is closed-packed while pronation is open-packed

Question 12

T or F: When the fibula fractures during an eversion ankle sprain, it is more likely due to a traction injury from ligamentous pull as opposed to the talus impacting the fibula during abduction/eversion of the talus/calcaneus.

Answer 12

False!

Question 13

Someone is lacking full supination of the subtalar joint, and is therefore, unable to achieve the closed pack position of this joint. This results in relative plantarflexion weakenss. Why?

Answer 13

The subtalar joint needs to achieve the closed packed position to be able to effectively maximize forces transmitted from the gastrocs/soleus to the forefoot. If this rigidity is lost, it is likel trying to jump on a trampoline from a stand still position (it doesn’t work because the energy is absorbed into the trampoline and you barely go anywhere).

Question 14

T or F: Medial ankle sprains occur about 85% of the time, but the damage is typically very mild due to the deltoid ligament being very strong.

Answer 14

False; lateral ankle sprains are 85%

Question 15

T or F: The transverse tarsal joints pronate with the subtalar joint to help with shock absorbtion during early to mid-stance, then supinate to help maintain lateral forefoot contact on the ground, and finally maintain supinations while subtalar also supinates in order for rigid push off lever.

Answer 15

True

Question 16

Which Ray is the least mobile but most stable?

Answer 16

2nd Ray!

Question 17

If someone has flexible pes planus, what type of shoes may be best, one with increased cushion or one with increased arch support?

Answer 17

Arch support; they lack the ability to supinate and create a rigid lever for push off so arch support helps create that lever.

Question 17

If someone has flexible pes planus, what type of shoes may be best, one with increased cushion or one with increased arch support?

Answer 17

Arch support; they lack the ability to supinate and create a rigid lever for push off so arch support helps create that lever.

Question 18

T or F: When distinguishing between tibialis anterior tendinopathy and MTSS, MTSS will be reproduced with resistance of ankle dorsiflexion and inversion.

Answer 18

False; Tib anterior tendionpathy will

Question 19

T or F: Peroneal tendinopathy is often secondary to a lateral ankle sprain

Answer 19

True

Question 20

T or F: You can avoid surgery for Compartment syndrome if you change from a rearfoot to a forefoot striker.

Answer 20

True! Reduces ground reaction force

Question 21

T or F: Someone with limited ankle dorsiflexion in closed chain will compensate with increased subtalar supination, which may contribute to the development of anterior shin pain.

Answer 21

False; PRONATION of the subtalar joint will make up for lack of DF

Question 22

Which of the following is NOT a key symptoms in someone with cuboid syndrome?
A. Pain with passive accessory mobility testing of the cuboid
B. Plantar foot pain just proximal to the base of the 5th metatarsal
C. Reproduction of familiar pain with weight bearing and push off during gait
D. Persistent pain about 1cm distal to the lateral malleolus following a lateral ankle sprain

Answer 22

D. Not from a sprain and on lateral side of plantar surface of foot

Question 23

T or F: When recovering from Achilles tendon repairs, it is important to maintain a non-weight bearing status for the first 3 weeks with all protocols due to the contractile requirements of the Achilles. For tarsal tunnel release, immediate weight bearing is possible.

Answer 23

False; accelerated rehab allows for immediate weight bearing while non weight bearing is recommended for 3 weeks with tarsal tunnel
