1
Q

what is Subtalar Neutral Position

A

The foot position where the subtalar, talonavicular, and calcanealcuboid are congruous (in position of neither pronation nor supination)

Q

what is Equinus

A

is a condition that causes limited ankle joint range of motion - ankle doesn’t flex upward (dorsiflex) as it should, and the foot ends up compensating (pronating)

Q

Leg Injuries associated with over supination

A

Achilles tendinitis
Peroneal tendinitis
Lateral knee and hip pain.

18
Q

How does Limited S-T joint motion effect​ the calcaneus during stance

A

keeps it in the inverted​ position

19
Q

Rigid Plantarflexed 1st Ray leads to what

A

Develop lateral instability of ankle

Callus under 1st & 5th MT heads

20
Q

how to accomidate Rigid Plantarflexed 1st Ray

A

Requires accommodative orthotic with cut-out for 1st ray or bar from 2nd - 5th MT

21
Q

when we are in resting positon what does the foot look like

A

eversion of heel rather than subtalar neutral (STJN)

22
Q

Gait cycles operates around RSP or STJN

A

RSP

23
Q

Low Dye taping effectivness

A

pronation, increase arch height before and after exercise, and decrease rear-foot motion

24
Q

how can low dye taping be used as a screening tool

A

used to access if a pt would benefit​ from a orthotic

25
Q

Eversion midtarsal

A

Navicular plantar medial
Cuboid dorsolateral

long axis

26
Q

Inversion midtarsal

A

Navicular dorsolateral
Cuboid plantarmedial

long axis

27
Q

dorsiflexion midtarsal

A

Navicular & Cuboid Dorsolateral
same direction

28
Q

PF midtarsal

A

Navicular & Cuboid Plantarmedial
same direction

29
Q

Ankle Sprains make up what precentage of ankle injuries

A

75%

30
Q

inversion sprain action

A

in and PF

31
Q

Inversion Sprains normal involve what ligaments

A

involves anterior talo-fibular ligament (ATF) and calcaneo-fibular ligament (CF).

Severe injury may also involve the posterior talo-fibular ligament.

32
Q

Risk Factors intrinsic for inversion sprains

A

Limited ankle DF ROM
Reduced ankle proprioception
Decreased balance
Factors reduce the ability of the dynamic stabilizers (peroneals) to react to perturbations in ankle position

33
Q

what sports do we often see intrinsic sprains

A

Basketball, volleyball, field sports

In soccer – being a defender and playing on natural grass as opposed to artificial increases risk for LAS

34
Q

what special test might be positive if there is an inversion sprain

A

anterior drawer and medial talar tilt tests.

35
Q

functional ankle instability can be cuased​ by what

A

caused by disturbed proprioception

PT - Balancing, single leg stance, return to position

PT aimed at co-ordination and strength of muscles around ankle to restore proprioception and thus stability

36
Q

Sinus Tarsi Syndrome is normally associated with what issues

A

a secondary complication of chronic inversion sprain in patients who also hyperpronate.

hyperpronation, talus displaces into sinus tarsi region resulting in irritation.

37
Q

what do we see with Sinus Tarsi Syndrome

A

Chronic pain and inflammation of lateral aspect of sub-talar joint (sinus tarsi).

38
Q

eversion sprain involve which ligaments

A

deltoid ligament, may also involve distal tib-fib interosseous membrane

39
Q

which is more present inversion or eversion sprain

A

inversion sprain

eversion i stabilized due to the distal fibula extends beyond​ the jt

40
Q

Deltoid ligament complex issues are associated with what

A

Lateral ankle sprains

Ankle syndesmosis injuries

Maisonneuve fracture (fx of proximal fibula with widening of the ankle mortise on x-ray)

Malleolar fractures

41
Q

what happens when distal tib fib joint when we DF

A

it opens up

42
Q

Mechanism of high ankle sprain

A

leg IR
foot ER
