Q

How do you MWM for lateral ankle sprains that are lacking DF?

A

stabilize medial malleolus, and give A-P force to lateral malleolus while pushing into DF with your hip
- sustain this hold for 15 sec

Q

How do you MWM the tibia for increased dorsiflexion?

A
  • have pt stand on table
  • put belt around their distal tibia and around your butt
  • stabilize talus with web of your hand
  • have pt lunge forward and you lean back into the belt

this brings tibia forward for increased DF motion

Q

What factors can cause medial tibial stress syndrome?

A
  • over-pronating when running
  • imbalance of inversion/eversion strength
  • repetitive eccentric contraction of soleus
  • high BMI, less running experience, poor training, bad shoes
  • previous history of MTSS

all the pounding of running irritates the periosteum

Q

What therapeutic exercise can we give for shin splints?

A
  • stretching (gastroc/soleus) and strengthening (tib post/ant)
  • cross train (take some load off of that soleus)
  • control inflammation
  • assess static and dynamic gait
  • assess shoe type and terrain they’re running on

21
Q

Why is achilles tendonopathy so difficult to treat?

A

poor blood supply and it’s a huge tendon

22
Q

T/F: Those with achilles tendonopathy see morning stiffness

A

true

23
Q

How can we treat achilles tendonopathy?

A

ECCENTRIC EXERCISE (once they can tolerate)

  • begin by stretching soleus/gastroc
  • strengthen surrounding muscles (tib post/ant)
  • can tape, use orthotics, wear boot
24
Q

How many reps of eccentric exercise should be done?

A

3 sets of 15

25
Q

How long should you avoid physical activity that stresses the tendon?

A

4-6 wks

26
Q

T/F: Need to slow down during the eccentric part of the contraction to reap benefits.

A

false, eccentric has a speed component so just go normal speed

27
Q

How could you progress eccentric exercise for achilles tendonopathy?

A

3 sets of 15, 2x/day, 7 days/wk; 12 wks

1) begin on floor bilaterally doing heel raises and drops
* then do unilaterally
2) progress to stair lowering and do bilateral then unilateral
3) add weight to shoulders now, continue on stair lowering

28
Q

What two muscles create a sling effect around the 1st met in the foot?

A

tib posterior and fibularis longus

29
Q

What muscle supports the medial longitudinal arch of the foot?

A

tib posterior

30
Q

What muscle supports the talonavicular joint during heel strike?

A

tib posterior

31
Q

With posterior tibial tendon dysfunction, where is the trauma located?

A

at the navicular tuberosity

32
Q

What are two ways we can assess for PTTD?

A

1) two many toes sign: toes extend out laterally

2) heel rise: look to see if 1st MET can DF and if there’s pain

33
Q

How can we treat PTTD?

A
  • taping

- exercise: lunges with foot, eccentric DF/eversion (to strengthen tib post), forefoot add/abd with plantarflexion

34
Q

What is the position of the foot with a forefoot valgus?

A

big toe down, little toe up

- compensates by supinating at subtalar, making foot rigid and less shock absorbant

35
Q

How does the subtalar joint compensate for a forefoot varus?

A

pronation

- does same for rearfoot varus

36
Q

What is the windlass effect?

A

MTP joint extension and stretch of plantar aponeurosis with PF

  • gives arch support and push off during gait
37
Q

Which of these issues is the most common and can cause posterior tibial tendon dysfunction?

a) rearfoot valgus
b) rearfoot varus
c) forefoot valgus
d) forefoot varus

A

B) rearfoot varus

38
Q

Excessive pronation during loading response and midstance can be due to what?

A

rearfoot varus

39
Q

Forefoot valgus can cause what compensation?

A

excessive/early supination in midstance

40
Q

Execessive pronation during midstance can be due to what?

A

forefoot varus

41
Q

How do we diagnose pes planus?

A

navicular drop test

42
Q

What can cause plantar aponeurosis?

A
  • too high of arch, fascia can be pulled too tight and cause pain
  • flattened foot stretches fascia and can be painful
  • overuse/inflammation
  • poor training/poor shoe
43
Q

What muscles are mostly involved with inversion ankle sprains?

A

peroneals

44
Q

What are the deficits common with inversion sprains?

A
  • lack of feedforward
  • peroneal endurance
  • inverter strength
  • neuromuscular/postural control
45
Q

Neuromuscular control and support for the ankle is dependent on what 4 things?

A

1) postural control
2) muscle strength (fib long/brev)
3) proprioception
4) muscle reaction time (wears out after awhile)

46
Q

How do we rehab an ankle sprain?

A

work on:

  • postural control with core stability (to reduce reliance on hip/ankle strategies)
  • ROM (limit inv/ev due to pain)
  • strength, power, and endurance of muscles (OKC, CKC, plyos)
  • neuromuscular control (balance, proprioception, unstable surfaces)
47
Q

What’s a good intro exercise for someone with inv/ev weakness?

A

have them move a towel on the floor to the right and left with their ankle while sitting

48
Q

What’s the dosage of postural training you should do?

A

3-5 times per wk, 4-6 wks

- do for athletes (may improve LBP) and elderly (to reduce fall risk)

49
Q

How long until we determine if someone is ready to return to sport?

A

once they have complete ROM and are at 80-90% of pre-strength
- can compare to other limb to figure this out

Or they can return once full practice is tolerated without injury

50
Q

T/F: Ankle bracing/taping may resolve edema.

A

true

51
Q

What is prophylactic ankle bracing? Does it work?

A

wearing brace before injury is proven to help prevent injury by 60-85%

  • wear during practice and games, but not all time
  • helps give proprioceptive feedback for muscles to work
  • BUT still work on strengthening, postural control/balance, and proprioception outside of brace as well
