Q

Can impact peak change and what are we focused on for the graph

A

yes it can change we are worried about the slope (Rate) of the ground force reaction

What does internal torque mean?

A

result of the muscles generated forces responding to gravity

19
Q

What is the area under a power curve

A

mechanical work

20
Q

What is positive work

A

concentric

21
Q

What is negative work

A

eccentric

22
Q

What is the path of center of pressure

A

runners strike from posterior lateral to anterior medial

23
Q

When you are analyzing running gait what should you start with

A

side view

24
Q

What 7 can you observe from side view

A

foot strike pattern
tibial angle
knee flexion during stance
hip extension late stance
trunk lean
overstride
vertical displacement

25
Q

what are the different types of foot strike

A
  1. forefoot
  2. rearfoot
  3. midfoot
26
Q

most runners use what time of foot strike? does it change with barefoot runners

A

mostly rearfoot
change to forefoot when running barefoot

27
Q

The closer the foot is to the body the _____ the foot inclination angle

A

smaller

28
Q

Depending on how long the stride is you can have 3 different ______ angles

A

tibial angles
extended vertical flexed

29
Q

We absorb _____ forces when the knee is bent during stance

A

more

30
Q

why might someone have decreased hip extension in late stance

A
  1. decreased hip flexibility
  2. decreased lumbar extension
  3. decreased hip rom
  4. decreased movement coordination
31
Q

If an individual has an upright posture during running they most likely have increased ________ joint stress

A

patellofemoral

32
Q

If an individual has increased vertical displacement they will have ______ GFR

A

increased stress

33
Q

When do you want peak hip flexion

A

during midswing

34
Q

From the posterior view you can evaluate

A
  1. step width
  2. heel eversion
  3. foot progression angle
  4. heel whip
  5. knee window
  6. pelvic drop
35
Q

which is more common medial or lateral heel whip

A

medial

36
Q

knee window can tell you about

A

knee valgus/ varus

37
Q

Pelvic drip can tell you about

A

hip abductions strength

38
Q

Arms are in response of what

A

the LE is doing

39
Q

Patellofemoral pain syndrome is common with

A

overstride
upright trunk

40
Q

ITB syndrome is common with

A

narrow stance

41
Q

Medial tibial stress syndrome is common with

A

high vertical force
overstride

42
Q

Is the prescription of shoe type evidence based?

A

no

43
Q

What should we worry about when it comes to shoe prescriptions

A

comfort
promote the preferred movement path

44
Q

During toe off do we supinate or pronate

A

supinate
