Q

Simple rotation

A

The turning or rolling of an object held at the finer pads approximately 90 degress or less fingers act as a unit (unscrewing a bottle cap)

Q

Shift

A

Q

Material Based Occupation

A

Wu & Associates
Materials vs imagery based occupation
Matterial based leads to: increassed reaction time, mvmt time, and muscle activity

Q

Image based occupation involves

A

“make believe or props instead of real objects and is much less effective for reganing motor control & coordinatied functional hand use

14
Q

Normal UE Movement

A

Hand initiates any mvmt sequence
Preshaping of fingers occurs for grasping objects
Grip formation develops btw 10-22 weeks
Infants reach for and intercept objects before that but w/o preshaping

16
Q

Grasp varies according to

A

an objects location size and shape

17
Q

2 types of grip

A

Power & Precision

18
Q

Requierments for Grasp

A

Hand must adapt to shape
Size
Use of object
Finger motions must be timed in relation to transport of object

19
Q

Factors affecting pregrasp hand shaping

A

Intrinisic
Extrinsic
Coordination of reach & grasp requires transport of the hand to be coordinated w/ the shaping of the fingers

20
Q

Key Components of UE control

A

locating a target involves coordinated mvmt of eyes, head, & trunk
Reach involves transportation of the arm & hand in space as well as postural support
Grasp, including grip formation, grasp & release
In-hand manipulaton skills

21
Q

Neuro pathology often involves loss of

A

cordinated coupling btw synergist ms & jts

22
Q

Disruption in coordination of mvmt affects

A

timing & trajectory of mvmt

23
Q

Neuro pathology also affects

A

time of mvmt

24
Q

Impaired anticipatory hand shapping results in

A

inaccurate hand closure around target

25
Q

Premature finger closure =

A

Unstable grasp in objects

26
Q

Inadequate finger opening occurs in relation to

A

different shapes & sizes of objects

27
Q

Force scaling =

A

errors in grasp (too lose to tight)

28
Q

Power side of hand

A

Ulnar

29
Q

Skills side of hand

A

Radial

30
Q

Newer UE Tx Interventions Include

A

Mirror Box Therapy
Contraint Induced Therapy
Robotics
Virtual Tx (WII)

31
Q

Assessments

A

Motor Activity Log
Arm Motor Ability Test (AMAT)
Box and Block Test
STREAM (stroke rehab assessment of mvmt)
