The Relationship Between Thicknesses and Isokinetic Strength of Hip Flexor and Extensor Muscles

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to investigate the relationship of hip muscle thicknesses measured by ultrasonography with hip flexion and extension strength and clinical parameters in prosthesis users with unilateral traumatic transfemoral amputation.

Detailed Description
-----------------
The aim of this study is to investigate the relationship of hip muscle thicknesses measured by ultrasonography with hip flexion and extension strength and clinical parameters in prosthesis users with unilateral traumatic transfemoral amputation. This study will be useful in understanding whether ultrasonography is an appropriate imaging method in the follow-up of changes in functional strength in the hip girdle in patients with unilateral traumatic transfemoral amputation.

Official Title

Arms and Interventions

| Intervention/Treatment |
| --- |
|Other: Isokinetic evaluations|Peak torque and total amount of work of hip flexors and extensors will be determined by the Cybex 6000 model computer-aided isokinetic system.|
|Other: Ultrasonographic evaluations|Ultrasonographic evaluations will be performed with a 5-12 MHz linear probe (Logic e portable; GE Healthcare, China). The thicknesses of the hip flexor (psoas major) and extensor (gluteus maximus) muscles will be measured while the patient is in the prone position, in accordance with the literature.|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 6-minute walking test (6MWT) | Functional performance will be assessed by 6MWT (in meter). Patients will be instructed to walk quickly, safely, and as much distance as possible over a rectangular path. | through study completion, an average of one month | 
| 10-meter walking test | The short-distance over-ground gait speed will be assessed using a 10-Meter Walk Test. Participants will be asked to walk at normal pace on a 10-meter walkway. | through study completion, an average of one month | 
| Timed up and go test | Timed up and go test will be used for quantifying functional mobility balance. Participants will be instructed to sit in a comfortable position on a 45-65 cm high steady chair with a backrest and armrest, with both arms resting on their thighs, and then quickly stand up and move towards and around a fixed cone 3 m away, return, and sit again. | through study completion, an average of one month |
