Comparison of Classical Prosthesis and Silicone Prosthesis

Primary outcomes

1. Visual Analogue Scale

   Time frame: through study completion, an average of one and a half months

   All patients will mark the severity of residual limb pain, sound limb pain and low back pain on a Visual Analogue Scale (VAS; from 0 (no pain) to 10 (worst pain)). The socket system, prosthetic foot and overall prosthesis satisfaction will be evaluated with a 10-point VAS (from 0 (absolutely dissatisfied) to 10 (absolutely satisfied)).

2. Short Form 36 (SF-36)

   Time frame: through study completion, an average of one and a half months

   The QoL of each patient will be assessed using the Short Form 36 (SF-36). The validity and reliability of the Turkish version of SF-36 has been demonstrated. SF-36 consists of 36 questions on eight different subscales that include physical functioning, role limitations due to physical health problems, bodily pain, general health perceptions, energy and fatigue, vitality, social functioning, role limitations due to emotional problems and general mental health. Each subscale of SF-36 is scored between 0 and 100, and higher scores illustrate better QoL.

3. Locomotor capacity index

   Time frame: through study completion, an average of one month

   The Locomotor Capabilities Index (LCI) is a validated measure of lower-limb amputees' ability to perform activities with prosthesis. The total LCI score is the sum of the item scores and can range from 0 (worst) to 30 (best).

4. Likert scale

   Time frame: through study completion, an average of one month

   Level of difficulty experienced during walking on straight road, walking uneven road, ascending stairs, descending stairs, ascending ramps and descending ramps will be recorded on a 5-point Likert scale ((1) very easy, (2) easy , (3) neutral, (4) difficult, (5) very difficult).
