Q

Somatosensory impairs are often neglected in therapy

Implications?

A
  • fork slips out of hand

36
Q

Tx of Somatosensory impairments

somatosensory impairs CAN improve…..

b/w R and L what side usually can improve more?

A

L. Hemiplegia < R. Hemiplegia

37
Q

Somatosensory Impairments

Principles of Tx:

A
  • Session starts and ends w/ tasks the pt CAN do
  • Tasks should be interesting to the pt
  • Vision and use of UNAFFECTED hand to teach perception
  • Freq. rests utilized!!!!!!!!!
38
Q

What would be some suggestions for Tx. w/ Somatosensory Impairs?

A
  • ID # of touches or lines——read article!!!
  • ID letters and #’s drawn on arm or hand
  • Find your thumb when blindfolded
  • Discrim. of shape, wt, texture of obj’s OR materials placed in hand
  • Passive drawing
39
Q

Somatosensory Impairment Tx’s

Specific UE tasks

Postural orientation

Aging process and Postural sway

A

INC’d sway

56

57
Q

Pusher Syndrome aka…

A

Contraversive Pushing

58
Q

Pusher syndrome

A

Pt pushes forcefully w/ the non-paretic extremities TOWARDS paretic side

59
Q

Pusher syndrome is likely due to damage where?

A

Ventral Posterolateral Nucleus of Thalamus

60
Q

When Pusher Syndrome is on the RIGHT

assoc’d w/….

A

Neglect

61
Q

When Pusher Syndrome on LEFT

assoc’d w/

A

Aphasia

62
Q

In Pusher Syndrome….

person feels that their upright is shifted by __________ from midline, thus they pushing to restore their perceived midline BACK to vertical

A

18-20 degrees

63
Q

Posture: Examination

Alignment should be in what?

Sitting or standing use a plumb line/grid

64
Q

Posture Exam:

Consider these things (balance support)

A

Foot position

BOS

65
Q

Posture exam:

wt. scales under ea. foot

why would you do this?

A

See if there is even distribution of wt b/w both sides or if they are leaning/overusing one side

66
Q

Posture Exam:

we want to attempt to standardize measurement

meaning?

A

Make sure that whatever we use is REPRODUCABLE

68
Q

In Symmetrical/Vertical Posture

What kind of feedback would you give?
