Thank you to the 95 participants in the survey for Prosthetists regarding
design of products in our industry for a senior design project. The results
were as followed.


1) In regards to product development, the most important area for the
industry to improve prosthetic devices is

Interface Materials- 49.47%

Fabrication Process- 16.84%

Components- 7.37% 7

Feet- 1.05% 1

Knees- 3.16% 3

Other (please specify)- 22.11%


If Other was chosen, the respondent was asked for additional comments. The
responses were as follows:

- suspension-no pistoning and simple

- assessing the outcomes/validity of devices

- K2 level simple inexpensive stance yeilding microprocessor controlled
knee.

- Upper Extremity

- Suspension mechanism

- socket design

- PROOF OF EFFACY

- Neurocorrelation coefficients

- interface design-not materials

- Interface Design

- Lower costs of products, especially MPKs

- Socket fitting consistency

- Upper extremity

- HD terminal devices

- Sockets the connection between prosthesis and human.

- socket design

- good k-2 knee

- discerning product to patient match

- More indepth training for Prosthetists students

- volume self accomodating sockets

- Interface and suspension methods


2) I expect a transtibial socket to maintain a comfortable fit for


a) 1-2 years- 23.16%

b) 2-3 years- 33.68%

c) 3-4 years- 12.63%

d) 4-5 years- 4.21%

e) More than 5 years- 3.16%

f) Other (please specify)- 23.16%


If Other was chosen, the respondent was asked for additional comments. The
responses were as follows:

- This is a difficult question to answer, as it depends alot on where the
amputee is (new amputee vs older residual limb)

- it just varies too much to set a time range

- maintaining fit is always dependent on residual limb maturity and patinet
weight gain and loss

- depends upon patient anatomiical changes, not universal

- Differs depending on age of amputation and weight change

- New amputee 1-2 yrs- seasoned-3-5 yrs

- Depends on unique histological dynamics

- 6-12 months for a new amputee and 12-18months for a mature lim

- Too many patient variables

- as long as there is no pysiologic change to teh pateint

- It depends on many things - age of amputee (child or adult) how long
since amputation you can expect the residual limb to lose volume as it
matures,

- I don't have a preconceived expectation. Patients limbs change at
different rates.

- Initial socket while limb is changing... 6mo to a year, definitive socket
on mature limb... 3 years ideally

- Patient dependent

- Depends on the patient's weight/volume changes

- deoebds ib age of limb and lifestyle

- Too many factors to predict ever

- 5-6 years was the lifespan of a prosthesis in the 1960s

- depends on the patient being fit, and the age of the patient. A less
active patient the socket should fit for a longer period of time vs an
active patient.

- depends on how new the pt is/rate of volume fluctuation

- Too many variables to predict.

- Depends on the patient. Weight fluctuation and limb volume changes vary
greatly patient to patient.

The responses from questions 3-5 to follow in part 2 of this post.

If you have any questions regarding the survey, please feel free to contact
me.
