1

What is the purpose of doing MCP rotation mob?

helps with general stretching for capsular limitations

2

Why do we need rotation in the fingers?

individual movements of the fingers
- mostly radial -

3

For UCL injury, what types of exercises would you do?

- flexion
- pronation

4

When you go from pronation to neutral, ______ are most active and working ________

- supinators
- concentric

5

When you go from neutral to supination, ______ are most active and working ________

- pronators
- eccentric

6

When you go from supination to neutral, _______ are most active and working _________

- pronators
- concentric

7

When you go from neutral to pronation, _______ are most active and working ________

- supinators
- eccentric

8

What group do you need to target with UCL injuries?

flexor pronators

9

best treatment for chronic tendinopathy

eccentric strengthening

10

finger mobility in order from most to least

1. thumb
2. 4/5
3. 2/3

11

During gripping, the fingers point

radially

12

What is the functional position of the hand?

30˚ extension
15˚ ulnar deviation

13

What are the two types of grips?

- power
- precision

14

4 types of power grip

- hook
- cylinder
- fist
- spherical

15

What sets the hook grip apart from the other power grips?

only one with no thumb

16

power grips
- hook

- MCP extended
- PIP and DIP flexed
- targets forearm flexors

17

power grips
- cylinder

- uses opposition
- fingers and thumb don't overlap

18

power grips
- fist

- uses opposition
- thumb and fingers overlap

19

power grips
- spherical

- opposition (i.e. holding a baseball)

20

precision grip aka

prehension

21

3 types of precision grips

- chuck pinch
- lateral or key pinch

chuck pinch other names

- 3 fingered pinch
- digital prehension

23

lateral or key pinch other name

lateral prehension

24

tip pinch other names

Tip to tip prehension

25

Which precision grip has no opposition?

lateral or key pinch grip

26

Which precision grip has the least power and the most precision?

tip pinch

27

Which precision grip is the most common with writing?

3 fingered pinch

28

How should you test grip strength?

- ideally 3 per level
- take average to remove testing error

29

handheld dynamometry
Which level will produce the most power and what will the graph look like?

- 2nd and 3rd from the closest
- bell curve

30

What will the bell curve look like with an injury?

bell curve with a lower apex

31

When would you see an irregular curve from handheld dynamometry?

if they aren't giving max effort

32

The dominant arm is generally _____ stronger than the nondominant

10%

33

handheld dynamometry
- testing procedure

- arm down by side, elbow 90˚
- hold, count to 4, look at number

34

What is used to measure pinch strength?

pinch-o-meter

35

Which grips can you measure using the pinch-o-meter?

- pulp to pulp (3 fingered pinch)
- lateral (key) pinch
