Relationship Between Gait Variability and Sensation

Study Overview
=================
Brief Summary
-----------------
Twenty individuals who were referred to receive physiotherapy will be participants of the study. Participants with lower limb loss will evaluate with the following assessment tools: Demographic datas; age, gender, height, body mass, year, side and level of limb loss will be recorded. Gait parameters (step length, variation of step length) will evaluate with Gait Trainer Biodex 2, at participant's preferred speed.Phantom sensation and phantom pain will be asked as existence or not. Sensorial loss will evaluate with Semmes Weinstein Monofilaments

Detailed Description
-----------------
Twenty participants with lower limb loss who were referred to receive amputee rehabilitation at Hacettepe University, Faculty of Health Sciences, department of Physiotherapy and Rehabilitation, Prosthetics and Biomechanics unit, will be the subjects of this study. Participants with lower limb loss will evaluate with the following assessment tools: Demographic datas; age, gender, height, body mass, year, side and level of limb loss will be recorded. Gait parameters (step length, variation of step length) will evaluate with Gait Trainer Biodex 2, at participant's preferred speed. To eliminate the learning effect, participants practiced at treadmill to determine appropriate gait speed. Once participants implied the preferred speed, they asked to walk at their self selected speed for 6 minutes. Data was recorded between the 2nd and 4th minutes at walk. Phantom sensation and phantom pain will be asked as existence or not. Sensorial loss will evaluate with Semmes Weinstein Monofilaments.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Step length variability assesment while walking. | Gait parameters (step length, variation of step length) will be evaluated with Gait Trainer Biodex 2, at participant's preferred speed. To eliminate the learning effect, participants practiced at treadmill to determine appropriate gait speed. Once participants implied the preferred speed, they asked to walk at their self selected speed for 6 minutes. Data was recorded between the 2nd and 4th minutes at walk. | Initially evaluation at first minute | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Phantom sensation and phantom pain assessment | Phantom sensation and phantom pain will be asked as existence or not. | Initially evaluation at first minute | 
| Sensory test | Sensorial loss will be evaluated with Semmes Weinstein Monofilaments (SWME) which is a noninvasive, inexpensive, rapid, and easy-to-apply test and often used in clinical routine assessment. The monofilaments will be applied to the stump along to the incision area and grafted skin area until the monofilaments bended for about one second. Participants will be instructed to say yes once they feel the monofilament on their skin. Each test will be repeated for 7 times whether the sensation loss was existed or not. Five true answers from 7 repeat will be accepted as normal feeling. Monofilament tests will beggin at 4.56 as known as protective sensation. | Initially evaluation at first minute |
