Flashcards in 04 Knee Measurement Deck (27):
1

normative values: males

5-0-135˚
(5˚ hyperextension/recurvatum)

2

normative values: females

10-0-135˚
(10˚ hyperextension/recurvatum)

3

flexion and extension: axis, SA, MA

axis: lateral femoral condyle
SA: to greater trochanter
MA: lateral malleolus

4

position for measuring extension

- supine
- foam roller under ankles
- have the patient actively extend by pressing down into the table

5

Why do you need to have a foam roller under the ankles when measuring extension?

so you can see the recurvatum

6

measuring flexion: active or passive?

active

7

position for measuring flexion: chronic/subacute patient

- flex hip to 90˚
- slowly bring heel to back of leg/butt as far as possible
- keep heel off table

8

position for measuring flexion: acute patient

slowly slide heel up on table as far as possible

9

What is the prone heel hike measurement used for?

assessing knee flexion contracture

10

prone heel hike: 1 cm =

11

position for prone heel hike

- prone
- knees off table edge
- measure distance between heel heights

12

What are the anthropometric measurements of the knee?

- 20 cm proximal
- 10 cm proximal
- joint pine
- 15 cm distal

13

anthropometric measurements: 20 cm proximal

measures quad/hamstring bulk

14

anthropometric measurements:
10 cm proximal

- suprapatellar capsule swelling
- VMO atrophy

15

anthropometric measurements:
joint line

inferior pole of patella

16

anthropometric measurements:
15 cm distal

gastrocs/soleus muscle bulk

17

MMT: extension
pt position

- tripod leaning back
- raise knee, then back down halfway

18

MMT: extension
- Why tripod position?

get the hamstrings out of the way

19

MMT: extension
PT stabilization

iliac crest or under the knee

20

MMT: extension
PT resistance

resist distal lower leg

21

MMT: extension
How would you do a 2/5?

sidelying or partial ROM

22

MMT: flexion
- pt position

- prone
- flex knee as far as they can, then back halfway
- about 65-70˚

23

MMT: flexion
- PT actions

- stabilize iliac crest
- apply resistance to distal lower leg, pressing straight down

24

What muscles is the MMT for flexion testing?

ALL hamstrings

25

MMT: flexion
- How do you isolate semitendinosus/semimembranosus?

- same test, internally rotated tibia
- push down and out/laterally

26

MMT: flexion
- How do you isolate the biceps femoris?

- same test, externally rotated tibia
- push down and in/medially

27

Why would you need to isolate the individual hamstrings for MMT?

If the first test breaks, want to know which muscles specifically are weak
