Flashcards in 03 Body Mechanics, Ergonomics, Scoliosis, Traction Deck (56):
1

ergonomics

branch of PT where evaluations of workplace are done to determine where improvements can be made for workers

2

Why are body mechanics so important?

- for individuals with LBP » lifting
- part of functional ADLs

3

FCE

functional capacity evaluation

4

What is the FCE used for?

- workman's comp patients
- determines how well a patient can perform job requirements

Are they able to lift the amount of weight necessary for the job?

5

When should the squat be assessed?

- LBP patients
- lower extremity pain

6

How do you assess the squat for patients?

- Ask them how they would pick something up off the floor
- look at AP and lateral view

7

How can inability to properly squat lead to LBP?

- range that's lacking from the hips and lower body is compensated by the low back
- more stress placed on it

8

What should you assess if there's a valgus collapse of the knees?

- hip strength
- closely related to one another

9

How do you maintain spinal curvature in the squat?

keeping the shoulders back

10

What must you have to be able to squat properly?

- mobility of lumbar and thoracic spine to maintain upright posture
- soleus flexibility
- gluteal and quad strength

11

Why is mobility of the lumbar and thoracic spine so important when squatting?

maintain upright posture

12

What are the two lifts from the floor?

- golfer's lift
- power/tripod lift

13

What is golfer's lift used for?

picking up small and lightweight objects off the floor

14

How to perform a golfer's lift

- opposite arm and leg used
- kick up behind to maintain an upright spine with lumbar lordosis

15

Why is hinging at the hip so important with the golfer's lift?

- keeps lordosis
- hels spine maintain normal curves (won't aggravate patients with LBP)

16

What is a limiting factor for the golfer's lift and how can it be addressed?

- hamstring tightness in stance leg
- can bend knee slightly when going down

17

What is the power tripod lift used for?

picking up larger objects off the ground

18

During the power/tripod lift, where is the object when you pick it up?

close to the body

19

What are two major lifestyle factors that can lead to slowing of healing?

- smoking
- nutrition

20

Important questions to ask about workstation ergonomics

1. Height of the desk and monitor
2. Does the chair have arm rests?
3. Lumbar support?
4. Do they use a keyboard?
5. Do they wear glasses?

21

Why is the presence or absence of arm rests important?

Can they get close enough to the desk?

22

What are the two types of scoliosis?

- structural
- nonstructural

23

How does structural scoliosis occur?

75-85% is idiopathic and occurs during adolescence

24

3 types of structural scoliosis

- thoracic
- lumbar
- thoracolumbar (double curve or S curve)

25

How is structural scoliosis named?

for the side that it curves toward

26

How do you determine the size of the scoliosis curve?

COBB angle

27

What is a significant Cobb angle?

greater than 60˚ impairs pulmonary function

28

What are some non-PT treatments for structural scoliosis?

- brace in adolescence to halt progression of the curve
- Harrington rod surgery to straighten the spine

29

When would you do PT for scoliosis patients?

when it's causing pain

30

Can you do PT for patients with structural scoliosis?

- can't change the curve if it's structural
- CAN help them manage the pain

31

What can be done for patients with non-structural scoliosis?

PT can affect the curve

32

Is scoliosis the likely cause of a patient's pain?

- just because they have a hx doesn't mean that any back pain they have is related to it
- determine the cause of pain through exam

33

In scoliosis, which direction does the vertebral body rotate toward?

to the convex side

34

Where does the spinous process rotate in scoliosis?

to the concave side

35

How does lateral convexity affect the ribs in the thoracic spine?

ribs move posteriorly on that side, causing a rib hump

36

For idiopathic structural scoliosis, what happens to the ribs when they bend over?

rib hump doesn't go away

37

For non-structural scoliosis, what happens to the ribs when they bend over?

rib hump goes away

38

How do you treat patients who have idiopathic structural scoliosis?

asymmetrical exercises (often on a physioball)

39

For a right thoracic curvature, how would you treat the erector spinae?

- R erectors are overstretched and weak, need to strengthen
- L erectors are tight and need to be stretched

40

For a right thoracic curvature, how would you treat the rhomboids and mid traps?

- R rhomboids and mid traps are tight and need to be stretched
- L rhomboids and mid traps are overstretched and weak, need strengthening

41

For a left lumbar curvature, how would you treat the erector spinae?

- R needs to be stretched
- L needs to be strengthened

42

Traction should be used with patients who have:

- negative repeated motions
- positive radicular symptoms

43

traction for chronic symptoms (DDD)

weight percentages

30-40% body weight
no more than 50%

44

traction for chronic symptoms (DDD)

ON:OFF time

30:10 (intermittent)

45

traction for chronic symptoms (DDD)

How long should you keep them on it?

- begin with 10-12 mins and progress to 20
- must stay with them through first cycle

46

traction for acute symptoms (HNP)

weight percentages

30-40% bodyweight
no more than 50%

47

traction for acute symptoms (HNP)

ON:OFF time

60:20

48

traction for acute symptoms (HNP)

How long should you keep them on it?

- start with 3-5 mins and progress to 15
- must stay with them through one full cycle

49

friction free table and settings

- table slides apart and you don't have to account for friction
- use lower BW% (closer to 30%)

50

non-friction free table and settings

- need to combat friction from the table
- use higher BW% (closer to 40-50%)

51

Setting up harnesses for lumbar traction? Where is the targeted area?

between the two harnesses

- thoracic below ribs
- pelvic at ASIS

52

Remember to tighten these:

- harness
- thoracic straps
- weight rope

53

progressive intermittent option for traction

- used to increase weight that's good for their first time
- progressive steps

54

For traction, it's easier to apply the lumbar strap in this position

standing

55

What do you need to instruct the patient not to do once you turn on the machine?

tell them not to lift the hips

56

When treatment is over, remember to do this before unhooking the patient

lock the table if it's friction free
