Q

How should a bone stress injury be managed in runners?

A
  1. Decreased weight bearing (pain free)
  2. Progressions must be pain free during and 24 hours following
  3. Non-impact exercise (maybe)
  4. Refer to nutritionist if needed
  5. Educate: risks, prevention, expectations

Q

How should Achilles Tendinopathy be managed in runners?

A
  1. Load management & PRE
  2. Orthotics & heel lifts
  3. Chronic: Participate with ≤5/10 pain
  4. Does not increase risk of rupture

  2. Anti-pronation taping (Acute)
  3. STM to calf trigger points
  4. Off-the-shelf orthotics (3 months)

17
Q

Which ground reaction force is smallest in amplitude and also most variable?

A

medial/lateral ground reaction force

18
Q

The active peak of the vertical ground reaction force occurs when the COM is at its [lowest/highest].

19
Q

Are contact forces greatest during the impact peak or active peak of the vertical ground reaction force?

20
Q

Joint moments and powers peak at or around [initial contact/midstance]

21
Q

When does the vertical impact peak increase? (3)

A

(1) running downhill
(2) slower cadence
(3) pronounced heel-strike pattern

22
Q

The majority of angular excursion and power occurs in what plane of motion during running?

A

sagittal plane

23
Q

When should you assess a runners form? (2)

A

(1) recurrent injuries potentially related to mechanics + training errors
(2) athlete seeking advice related to performance and running efficiency

24
Q

What should you be observing for in the frontal plan of running analysis? (5)

A
  1. Joint center alignment
  2. Pelvic lateral tilt
  3. Proximity of knee joints
  4. Medial-lateral foot placement
  5. Toe-out
25
What joint center does “joint center alignment” in the frontal plane observe?
the knee's joint center! identifies either dynamic valgus (medial) or varus (lateral) alignment
26
If a runner has excessive pelvic lateral tilt, what also may be occurring at their knees?
dynamic knee valgus
27
What is a secondary measure of joint center alignment and pelvic lateral tilt?
proximity of knee joints
28
What can cross over during running increase strain on? (3)
lateral hip, lateral thigh, and medial distal tibia
29
What does medial-lateral foot placement indicate?
if there is any amount of cross over/location of the foot with respect to the whole body's line of gravity
30
What would excessive toe-out indicate? (3)
(1) hip capsule or muscle tightness (2) acetabular and femoral eversion (3) knee/tibial eversion
31
What is observed in the sagittal plane during running analysis? (2)
(1) initial contact (2) midstance and midflight
32
What can measurement of the foot strike angle indicate?
foot strike pattern (i.e. heel, midfoot, or forefoot)
33
The A-P foot placement is directly associated with the [braking impulse/propulsive impulse].
braking impulse
34
If there is a greater distance between the foot and the body's line of gravity, do the have a [lesser/greater] braking impulse?
greater
35
What is the ideal knee flexion angle at initial contact?
15-20 degrees
36
If at initial contact, the knee is more extended than expected, what is occurring? (2)
(1) overstriding (2) aggressive heel-strike pattern
37
Between midstance and midflight, which is the highest and lowest points for COM vertical excursion?
midstance = lowest midflight = highest
38
What is happening if there is a large excursion in vertical COM? (2)
(1) increase in active peak of vertical GRF (2) increase in metabolic cost
39
What would a 5-10% increase from preferred step rate lead to? (3)
Reduced: (1) peak vertical ground reaction force (2) loading rate (3) braking impulse
40
What would less heel strike do? (1)
Reduce braking impulse
