Lecture 1: Overuse Injuries At Hip- Hamstring Strain

Front 1

What is the etiology of Hamstring Strains?

Back 1

OVERUSE
1. Muscular imbalance
a. Quad weakness- hams try to pick up slack
b. Hamstring dominance- also weak- hams used to stabilize the pelvis
c. Short hamstrings- dominance perpetuated

Front 2

H, A of Hamstring Strain?

Back 2

A:
1. Acute, local hamstring pain
2. Mechanism of injury- sprinting to 1st base; raquet sports
H:
1. Recurrence
A:
1. Local tenderness and edema in mm belly
2. Ecchymosis
3. Hamstring atrophy
4. Gluteal &/or gastroc atrophy

Front 3

R for hamstring strain- Arthrokinematics?

Back 3

WNL

Front 4

R for hamstring strain- STTT?

Back 4

1. Pain with resisted hip ext and/or knee flexion
2. Active hip ext and knee flexion depending on reativity
3. A/PROM for hip flexion and/or knee ext at (end range)

Front 5

T for hamstring strain?

Back 5

1. Play and tone impaired
2. Length and strength impaired

Front 6

Management of hamstring strain?

Back 6

1. PRICE
2. Reduce tone
3. Restore play and length of soft tissue and neural tissue (AROM before PROM)
4. retrain faulty mvt patterns
5. Strengthen abs prn
6. Strengthen quads prn

Front 7

Dx groupings of hamstring strain?

Back 7

1. Acute onset
2. Local hamstring pain 2nd to hamstring contraction and/or lengthening

Front 8

Diff Dx of Hamstring strains>

Back 8

Hamstring strain vs. umbar radiculopathy vs peripheral nn. irritation
-differentiate by distinguishing mech of injury and ANTT

Front 9

What are some special tests for hip?

Back 9

1. Alignment Tests
a. Craigs Test (Ryder's Method)
b. Q angle
2. Joint provocation
a. Scouring (Quadrant test)
b. FABERE'S test: flex, abd, ER, ext
-Sup fig 4
-Prone fig 4
3. Strength test:
a. Trendelenburg- trunk lean and SB-> + if this happens with one-legged stance
4. Length test:
a. 2 jt hip flexor
b. Modified Ober
c. Hamstring
d. Gastrocsoleus
