1

Thenar eminence atrophy signifies involvement of which nerve?

median

2

Hypothenar eminence atrophy signifies involvement of which nerve?

ulnar

3

Can you palpate the tendons in the palm?

not distinctly, palmar aponeurosis

4

What can you palpate in the palm?

- nodules
- tenderness
- trigger finger

5

How can you palpate for trigger finger?

- tenosynovitis
- pain

6

palpation of metacarpals

- feeling for disruptions, pain, tenderness
- assess mobility

7

MCP/PIP palpation

- nodules could indicate RA
- swan neck deformity

8

palpation of finger tips

"tufts"
- hypersensitivity
- infection

9

What are the measurements you'll do on the fingers?

- flexion
- extension
- abduction
- adduction

10

gonio norms
MCP flexion

90˚

11

gonio norms
PIP flexion

100˚

12

gonio norms
DIP flexion

90˚

13

gonio norms
MCP extension

45˚

14

gonio norms
PIP extension

15

DIP extension

16

gonio norms
finger abduction

- no normative data, but do bilateral comparison
- axis over MCP

17

gonio norms
adduction

If you can get to midline with all fingers, considered normal

18

gonio norms: thumb
MCP flexion

50˚

19

gonio norms: thumb
MCP extension

20

gonio norms: thumb
PIP flexion

80˚

21

gonio norms: thumb
PIP extension

20˚

22

gonio norms: thumb
flexion at CMC joint

15˚

23

gonio norms: thumb
extension at CMC joint

20˚

24

gonio norms: thumb
abduction

70˚

25

gonio norms: thumb
opposition

measure distance between thumb and digital palmar crease of pinky

26

flexion at CMC joint
axis, stationary, moving

- axis at CMC
- stationary at ventral midline of radius
- movement arm is 1st metacarpal

27

thumb abduction
start position

- adducted (soft tissue approximation)
- line up axis with radial styloid
- starting position along second metacarpal

28

MMT
MCP flexion

- uncurl fingers, leave knuckles bent
- apply palmar pressure

29

MMT
PIP flexion

- all fingers extended except the one you're testing
- flex all the way down, half back
- apply palmar pressure

30

MMT
DIP flexion

- stabilize middle phalanx on both sides
- flex, bring back halfway
- apply palmar pressure

31

MMT
MCP extension

- extend MCP
- apply pressure dorsally

32

MMT
PIP and DIP

- not standard MMT for the fingers
- 0˚ is standard

33

MMT finger abduction/adduction

Distinguishing between 4 and 5

can't distinguish

34

MMT finger abduction/adduction
grade = 3

can adduct, but can't stand resistance

35

MMT finger abduction/adduction
grade = 2

- full abduction
- can't get full adduction

36

MMT finger abduction/adduction
adduction

- hold fingers together
- PT tries to pull them apart

37

MMT thumb
MP flexion

- can't do against gravity
- stabilize proximal joint, add pressure to extension

38

MMT thumb
IP flexion

- can't do against gravity
- stabilize at MCP joint, add pressure to extension

39

MMT thumb
IP extension

do against gravity

40

MMT thumb
abduction

- stabilize metacarpal
- can specify between the two muscles by location

41

MMT thumb
opposition

- oppose, then back halfway
- apply resistance in both directions

42

MMT thumb
adduction

- fully abduct, adduct halfway
- apply pressure

43

manual therapy
arthrokinematics of the fingers

concave on convex

"the arthrokinematic, osteokinematic, and therapeutic motions are in the same direction"
