Completed
Conditions
Amputation
Interventions
Other: The effect of using two different prosthetic feet on functional capacity, pain severity, satisfaction level and quality of life
Registration Number
NCT04759014
Lead Sponsor
Gaziler Physical Medicine and Rehabilitation Education and Research Hospital
Brief Summary

Background: Prescribing optimal prosthetic feet to ensure successful rehabilitation is difficult since there are no generally established clinical guidelines based on objective data.

Aim: To investigate the effect of using non-articulated dynamic foot (non-articulating ankle, NAA) and dynamic foot with hydraulic ankle (articulating hydraulic ankle, AHA) on functional capacity, pain severity, satisfaction level and quality of life (QoL) in high activity patients with unilateral transtibial amputation.

Detailed Description

Background: Prescribing optimal prosthetic feet to ensure successful rehabilitation is difficult since there are no generally established clinical guidelines based on objective data.

Aim: To investigate the effect of using non-articulated dynamic foot (non-articulating ankle, NAA) and dynamic foot with hydraulic ankle (articulating hydraulic ankle, AHA) on functional capacity, pain severity, satisfaction level and quality of life (QoL) in high activity patients with unilateral transtibial amputation.

Methods: Forty-two patients with unilateral transtibial traumatic amputation will be participated in this cross-sectional study. Functional capacity will be evaluated using the six-minute walking test (6MWT). The severity of residual limb pain, sound limb pain and low back pain will be evaluated with a 10-point Visual Analogue Scale (VAS). The socket system, prosthetic foot and overall prosthesis satisfaction will be evaluated with a 10-point VAS. The QoL of each patient will be assessed using the Short Form 36 (SF-36).

Primary Outcome Measures
NameTimeMethod
The six-minute walking test (6MWT)through study completion, an average of one and a half months

Functional capacity will be evaluated using the six-minute walking test (6MWT). The 6MWT evaluates walking function and endurance. Patients will be instructed to walk quickly, safely, and as much distance as possible along a rectangular path. The 6MWT is both valid and reliable among individuals with lower-limb loss.

Visual Analogue Scalethrough 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)).

Short Form 36 (SF-36)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.

Secondary Outcome Measures
NameTimeMethod
Likert scalethrough study completion, an average of one and a half months

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).
