Running Injuries from Kines Flashcards
What percent of runners experience PFPS?
25-40%
In pt’s w/PFPS, what kinematic changes are commonly seen?
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
In pt’s w/PFPS, what strength deficits are commonly seen?
Hip Abduction Hip ER Hip Extension Delayed & shorter glute med activation time Maybe weak quads
PFPS Interventions
Strengthening of hip ER's, abd's, & quads PNF stretching Orthoses Proprioceptive (biofeedback) training Taping Gait Retraining
What is the 2nd most common running injury & leading cause of lateral knee pain?
ITBS
What contributes to ITBS in runners?
Slow training pace
Female
Short stature
High weekly mileage
What are the 2 theories for why ITBS devos?
Compression & Friction Theories
Explain the friction theory of ITBS
Knee flexion impinges the ITB, which causes friction on it
Explain the compression theory of ITBS
Combined hip adduction & knee IR stretches the ITB
What kinematic changes are commonly seen in pt’s w/ITBS?
IC: Decr hip add, tibial IR, & eversion
Stance: Incr hip add & tibial IR
What is the main sx of plantar fasciitis?
Pain at the inside of the heel
How long does it typically take for PF to resolve?
6-18mo
What are the risk factors for PF in runners?
Older age Higher Weight Longer time running High weekly mileage Incr in intensity, frequency, & duration
Why do the risk factors for PF cause PF?
They incr strain on the plantar fascia
What does PF cause?
Incr stiffness & decr shock absorption of plantar fascia
What kinematic changes are seen in pt’s w/PF?
Altered ankle ROM
Pes Cavus/Planus
Incr loading rate
Incr magnitude of impact
Why does pes cavus contribute to PF?
Incr mechanical stress on fasica
Incr stiffness
Decr shock absorption
Why does pes planus contribute to PF?
Causes incr loads on med calcaneus & plantar area
Why does incr loading rate contribute to PF?
Faster loading rate means incr magnitude of impact
How is PF tx’ed?
Manual Therapy
Jt & ST mobes
Stretching of Achilles & PF
Taping, Orthoses, & Night Splints
What are the sx’s of MTSS?
Pain & tenderness along the posteromedial tibia
What are the kinematic changes seen w/MTSS?
Decr hip ER
Decr PF
Navicular drop
Explain the pathophysiology of MTSS
Incr pronation(Navicular drop) causes tibial rotation & bending, which leads to higher strains on the tibia
Who is more likely to suffer from stress fx’s?
Females
What are the kinematic changes seen w/tibial stress fx’s & what are the implications?
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
What is the tx for tibial stress fx’s?
Modified WB/Boot
Activity Restriction
Gait Retraining
When doing gait retraining for a pt w/tibial stress fx’s what should be done?
Get pt to run quieter
Decr stride length
Incr cadence
