1
Q

What percent of runners experience PFPS?

A

25-40%

2
Q

In pt’s w/PFPS, what kinematic changes are commonly seen?

A

Incr Hip Adduction–>During running, jumping, & squatting

Incr Hip IR–>During running, jumping, & step-down tasks

Excessive Dynamic Knee Valgus

Excessive Eversion–>Causes bow string force on patella

3
Q

In pt’s w/PFPS, what strength deficits are commonly seen?

A
Hip Abduction
Hip ER
Hip Extension
Delayed & shorter glute med activation time
Maybe weak quads
4
Q

PFPS Interventions

A
Strengthening of hip ER's, abd's, & quads
PNF stretching
Orthoses
Proprioceptive (biofeedback) training
Taping
Gait Retraining
5
Q

What is the 2nd most common running injury & leading cause of lateral knee pain?

A

ITBS

6
Q

What contributes to ITBS in runners?

A

Slow training pace
Female
Short stature
High weekly mileage

7
Q

What are the 2 theories for why ITBS devos?

A

Compression & Friction Theories

8
Q

Explain the friction theory of ITBS

A

Knee flexion impinges the ITB, which causes friction on it

9
Q

Explain the compression theory of ITBS

A

Combined hip adduction & knee IR stretches the ITB

10
Q

What kinematic changes are commonly seen in pt’s w/ITBS?

A

IC: Decr hip add, tibial IR, & eversion

Stance: Incr hip add & tibial IR

11
Q

What is the main sx of plantar fasciitis?

A

Pain at the inside of the heel

12
Q

How long does it typically take for PF to resolve?

A

6-18mo

13
Q

What are the risk factors for PF in runners?

A
Older age
Higher Weight
Longer time running
High weekly mileage
Incr in intensity, frequency, & duration
14
Q

Why do the risk factors for PF cause PF?

A

They incr strain on the plantar fascia

15
Q

What does PF cause?

A

Incr stiffness & decr shock absorption of plantar fascia

16
Q

What kinematic changes are seen in pt’s w/PF?

A

Altered ankle ROM
Pes Cavus/Planus
Incr loading rate
Incr magnitude of impact

17
Q

Why does pes cavus contribute to PF?

A

Incr mechanical stress on fasica
Incr stiffness
Decr shock absorption

18
Q

Why does pes planus contribute to PF?

A

Causes incr loads on med calcaneus & plantar area

19
Q

Why does incr loading rate contribute to PF?

A

Faster loading rate means incr magnitude of impact

20
Q

How is PF tx’ed?

A

Manual Therapy
Jt & ST mobes

Stretching of Achilles & PF

Taping, Orthoses, & Night Splints

21
Q

What are the sx’s of MTSS?

A

Pain & tenderness along the posteromedial tibia

22
Q

What are the kinematic changes seen w/MTSS?

A

Decr hip ER
Decr PF
Navicular drop

23
Q

Explain the pathophysiology of MTSS

A

Incr pronation(Navicular drop) causes tibial rotation & bending, which leads to higher strains on the tibia

24
Q

Who is more likely to suffer from stress fx’s?

A

Females

25
Q

What are the kinematic changes seen w/tibial stress fx’s & what are the implications?

A

Incr peak rearfoot eversion–>Incr torsional load on tibia
Incr knee stiffness–>Can’t shock absorb as effectively
Incr hip adduction–>Pt absorbs in frontal plane
Incr vertical loading rate & peak tibial shock

26
Q

What is the tx for tibial stress fx’s?

A

Modified WB/Boot
Activity Restriction
Gait Retraining

27
Q

When doing gait retraining for a pt w/tibial stress fx’s what should be done?

A

Get pt to run quieter
Decr stride length
Incr cadence
