Evaluation of Muscle Thickness and Balance in Young and Older Adults

Study Overview
=================
Brief Summary
-----------------
This study evaluates muscle thickness of trunk and lower limb and balance in young and older healthy adults. The participants will be evaluated muscle thickness for 14 different muscle and balance which evaluated by computerized force plate system.

Detailed Description
-----------------
Aging had an adverse affect on musculoskeletal system and balance parameters. Decreased muscle strength or thickness negatively affect person's balance control. But there are no information in the literature about the relationships between muscle thickness and balance in healthy subjects. In addition to, it is not known which muscle responsible for balance. Therefore, this study will evaluate muscle thickness via ultrasonography and balance in young and older adults. Balance will be evaluated computerized Balance system. Muscle thickness for different 14 muscle ( diaphragm, transversus abdominis,multifidus, longissimus, quadratus lumborum, rectus abdominis, external and internal obliques, rectus femoris, vastus intermedius, vastus lateralis, tibialis anterior, gastrocnemius, soleus) will be evaluated by ultrasonography at the right side. Only diaphram muscle will be evaluated both right and left side.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Experimental Group: Balance analysis<br>Sixty older subjects will be evaluated in this study.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Limits of Stability | Limits of stability test evaluates dynamic balance of participants. Computerized balance system measured limits of stability for forward, backward, right and left side movements. It calculates the maximum distance a person can lean without losing balance. The unit of measure is centimeters. The higher value is indicated the better balance. | 15 minutes | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Muscle thickness | Muscle thickness in millimeters by Ultrasound | 30 minutes | 
| Postural Sway | Postural sway in centimeters by computerized balance system | 15 minutes | 
| Fear of falling | Fear of Falling will be evaluated by Fall Efficacy Scale - International is a questionnaire that assesses fear of falling. The total scores range from 16 absence of concern to 64 extreme concern. | 15 minutes | 
| Joint position sense | Knee joint position sense test will be evaluated using an isokinetic dynamometer. The testing included passive positioning performed by the assessor and active-repositioning performed by the participants. As the difference between the target degree and the degree is increased, the sense of position worsens. | 15 minutes |
