1
Q

What is the lowest level goal for UE function?

A

To make the UE mobile/ comfortable but nonfuncitonal

2
Q

What is the highest level goal for UE function?

A

To use the UE as a manipulator to reach and grasp objects

3
Q

The UE can be used as a ____ to hold objects against the body and as a _____ to deal with dexterous/ manipulation type activities.

A

Stabilizer

Gross Assist

4
Q

List 3 prerequisites needed for ‘normal’ UE function.

A
  1. Postural Control
  2. Vision and Visual Perception
  3. Somatosensory function
5
Q

What is Fitt’s Law?

A
MT= a+b (log2 (2D/W))
MT= movement time
D= Distance between the person and the object 
W = object width
6
Q

Explain FItt’s law relative to movement time, distance, and object width.

A

As object width gets larger, movement time gets smaller because it is easier to grasp and manipulate

As distance increases, the movement time get larger because it gets more difficult to manipulate the object

7
Q

Accuracy demands of the task are decreased when a ____ release is added and increased when a ____ release is added.

A

Accuracy demands decrease when CRUDE release added

Accuracy demands increase when PRECISION release added

8
Q

Describe a grasp and 1 grasp manipulation.

A

Grasp: fingers manipulating/ lifting objects

Grasp with rotation: grasping an object and then turning it

9
Q

Describe a pinch and 1 pinch manipulation.

A

Pinch: Contact between index finger and thumb

Pinch with Rotation: turning a key

10
Q

What is the hardest task to recover and most difficult task to perform with the hand?

A

Isolated finger flexion and extension (I.e. typing and playing piano)

11
Q

____ % of stroke survivors suffer from shoulder pain.

A

70-80%

12
Q

List 4 signs and symptoms associated with shoulder pain experienced post stroke.

A
  1. GH Alignment (subluxation)
  2. Edema
  3. Spasticity/Dystonia
  4. Thalamic Pain
13
Q

What is thalamic pain? What is used to treat it?

A

Generalized response to non-noxious stimuli

Treated with NEUROTONIN

14
Q

What occurs with inferior shoulder subluxation? Cause?

A

Inferior shoulder subluxation impinges the head of the humerus, causing the humeral head to move anterior

Cause: Lack of muscle pump increases fluid resulting in EDEMA

15
Q

List 2 secondary impairments associated with shoulder subluxation.

A
  1. Damage to shoulder capsule

2. Possible impingement of the subclavian vein

16
Q

List 4 interventions used to treat shoulder subluxation.

A
  1. Positioning: support UE with pillows or lap tray when using W/C
  2. Sling/Hemi-Sling
  3. Taping: to facilitate deltoid and supraspinatus contraction
  4. Electrical Stimulation
17
Q

List 3 interventions used to treat edema.

A
  1. Compression garments
  2. Correct GH subluxation
  3. Positioning (at level or higher than level of the heart)
18
Q

List 1 intervention to treat somatosensation issues.

A

TENS set up with the glove set to sub-sensory threshold so the patient can’t feel it; left on for hours

Expands cortical representation of affected hand in brain to reduce pain and spasticity

19
Q

List 5 interventions used to improve strength and motor control of the UE.

A
  1. PNF Diagonals (D1)
  2. E-stim
  3. Splinting/Bracing
  4. Gravity Eliminated Open Chain
  5. Train rotational planes (IR/ER, supination/pronation)
20
Q

Bimanual practice decreased ____ and increased ______.

A

Decreased trans-callosal inhibition

Increased ipsilateral control
