From: Theoretical implementation of prior knowledge in the design of a multi-scale prosthesis satisfaction questionnaire

Item

Statement

1

In everyday life I am satisfied with the fit of my prosthesis

2

I am satisfied with the fit of my prosthesis to my stump

3

I am satisfied with the ability to walk when using my prosthesis

4

I am satisfied with the ability to sit when using my prosthesis

5

I am satisfied with the ability to walk when using my prosthesis

6

Keeping my balance while standing is easy for me

7

Keeping my balance while walking is easy for me

8

Putting on my prosthesis is easy for me

9

My prosthesis makes sounds (squeaking, clicking) frequently

10

I feel uncomfortable because of the sounds my prosthesis makes

11

I feel socially hindered because of the outer appearance of my prosthesis

12

I would consider a longer battery life of my prosthesis useful

13

I often experience pressure marks on my stump

14

I often experience swellings on my stump

15

After prolonged periods of wearing my prosthesis I experience problems with its fit

16

My prosthesis’ fit is regularly influenced by sweat inside it

17

I use a technical aid to improve the fit of my stump in the prosthesis

18

I have to adjust the socket of my prosthesis to my stump several times a day using additives

19

I use textiles (sock, liner) to adjust for the reduced volume of my stump

20

I use a technical aid to counteract the loss of volume of my stump

21

I regularly experience difficulties in everyday life due to a swollen stump

22

My prosthesis’ socket adjusts itself independently to the shape and volume of my stump

23

In walking, moving the prosthesis requires more muscle force than moving my unaffected leg

24

I would like my prosthesis to offer more support in order to reduce the amount of strength required for walking

25

I have pain in my phantom limb because of the prosthesis socket

26

I feel safe and stable during the stance phase of my prosthesis

27

I feel safe and stable during the swing phase of my prosthesis

28

I would like to have more stability during swing phase

29

I feel comfortable with my appearance when I’m in public

30

I feel like I have a natural gait

31

I am satisfied with my ability to stretch out the prosthesis

32

I would like my prosthesis to offer more mechanical/electronic support while extending it

33

I would like my prosthesis to offer more mechanical/electronic support while flexing it

34

I frequently adjust my speed while walking

35

I feel uncomfortable when I cannot change my speed while walking

36

I experience problems while trying to change my walking speed with my current prosthesis

37

I want to be able to change my walking speed on my own

38

I am satisfied with switching from standing to walking

39

Climbing stairs is difficult for me

40

I feel insecure about my prosthesis

41

My prosthesis is designed to climb stairs with it

42

I regularly stumble while climbing stairs

43

I can climb stairs by alternating between both feet

44

I climb stairs by placing the healthy leg on them first and following with the prosthesis

45

I can bend over with my prosthesis

46

I can lift heavy objects from the floor

47

I feel safe and secure while compensating for a loss of balance with my prosthesis

48

I am satisfied with suspension in initial heel contact

49

I am satisfied with suspension during extension

50

I am satisfied with suspension of my foot prosthesis

51

I have difficulty moving with my foot prosthesis while walking on uneven ground or up an incline

52

I regularly get caught on bumps with my foot prosthesis

53

I lift my foot by using my hip to get enough space to the ground

54

My prosthesis offers mechanical/electronic support while rolling over from heel to toes

55

I can adjust my prosthesis adequately regarding the heels of my shoes

56

When I look at my legs in everyday life, my prosthesis seems so belong to my body

57

The perception of my prosthesis in daily use is very close to the perception of the corresponding part of the body

58

I experience the prosthesis as a part of me

59

I experience the prosthesis as my new leg

60

I experience the prosthesis as part of my body

61

62

I experience the prosthesis in the place of my former real part of the body

63

I feel the spatial position of my prosthesis without looking at it

64

I can feel ground properties with my prosthesis

65

I experience something touching my prosthesis as touching on the corresponding part of my body

66

It seems to me like I can control the prosthesis at all times

67

I can ease itching at the corresponding part of my body by scratching my prosthesis

68

I often have blisters on my stump because of an ill-fitting socket

69

I feel uncomfortable with the weight of my prosthesis in everyday use

70

I feel uncomfortable with the size of my prosthesis in everyday use
