Sitting Balance

Question 1

What are the essential components of sitting? (4, p. 69)

Answer 1

1. Head and trunk erect
2. Shoulders over the hips
3. Weight evenly distributed
4. Ability to reach beyond arm’s length and return to vertical.

Question 2

What are some common kinematic deviations of sitting. 3 points. (week 4, p. 1)

Answer 2

• Falling to affected side
• Decr. WB on affected side
• Decr. ability to reach to affected side

Question 3

What is the NSF evidence for sitting training?

Answer 3

Practice reaching beyond arm’s length with supervision - B.

Question 4

What is a good study to quote about sitting training evidence? (week 4, p. 3)

Answer 4

Dean (1997)
Reach beyond arm’s length >3000 times in 2 weeks increased reaching distance and speed. Also increase GRF through affected leg, which helped with STS.

Question 5

What are the potential impairments for falling to the affected side? (4 points, p. 70)

Answer 5

Strength LL extensors
Coordination of LL extensors
Sensation of LL
Perception - loss of orientation to vertical

Question 6

What are the potential impairments of decreased weight bearing on the affected side? (3 points, p. 70)

Answer 6

Strength of LL extensors
Coordination of LL extensors
Sensation of LL.

Question 7

What are the potential impairments of decreased ability to reach beyond arm’s length and return to vertical? (3 points, p. 70)

Answer 7

Strength of LL extensors
Coordination of LL extensors
Sensation of LL.

Question 8

How might you strengthen very weak LL extensors? 4 points.

Answer 8

• pressure cuff under knee
• block at end of bed
• Gravity minimised exercises
• tilt table

Question 9

Give some examples of supervised sitting practice (3 points, week 4, p. 4)

Answer 9

• Sitting with a wall on intact side
• Sitting and reaching
• Sitting with feet on scales
