The Effect of Cycle Ergometer With Biofeedback on Deep Sensation in Elderly Patients With Knee Osteoarthritis

Study Overview
=================
Brief Summary
-----------------
The aim of the randomized controlled study is to investigate the effects of the cycle ergometer with biofeedback on deep sensation in elderly people who has knee osteoarthritis

Detailed Description
-----------------
Participants will be randomly divided and registered into 2 groups: Thera-train tigo group (TG) or control group(CP) For 20 participants 20 minute tens, 5 minute ultrasound, 10 times with 2 sets quadriceps isometric exercise will be applied. The other 20 participants will use Thera-train tigo for 20 minute in addition to tens, us, quadriceps isometric exercise. Conditions of the participants will be measured before(1st day) and after(15th day) a span of 3 week treatment. We will use Demographic Information Questionnaire, Western Ontario and McMaster Universities (WOMAC) osteoarthritis index, Physical Activity Scale for the Eldery (PASE) and 6 minute walking test for all patients. Then we will measure knee vibration sense with diapason. Knee joint position sense will be measured with a digital goniometer.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Cycle Ergometer Group (CEG)<br>Isometric exercises Transcutaneous electrical nerve stimulation Ultrasound Cycle ergometer | Other: Cycle Ergometer<br>* Patients will attend cycle ergometer exercise. Volunteers will monitor their pedaling forces as right and left force. They will try to make these forces equal while they are pedaling.<br>Device: Transcutaneous electrical nerve stimulation<br>* Transcutaneous electrical nerve stimulation will be used for the reduction of pain. TENS will be used 5 times in a week for 3 weeks. Each procedure will take 20 minutes.<br>* Other names: TENS;Device: Ultrasound<br>* Ultrasound will be used for increase the permeability of cells to treat pain and inflammation. US will be used 5 times in a week for 3 weeks. Each procedure will take 5 minutes<br>* Other names: US;Other: Isometric exercises<br>* The aim of the isometric exercises is increasing muscle strength. Each session patients will do quadriceps isometric exercises 5 times in a week for 3 weeks<br>|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Diapason survey | Diapason will be used to survey vibration sense to evaluate deep sensation | 3 weeks | 
| Digital Goniometer | Digital Goniometer will be used to measure angle of the knee position to evaluate deep sensation. | 3 weeks | 
| 6 Minute Walking Test (6MWT) | Six Minute walking test will be used to evaluate functional capacity of volunteers | 3 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The Western Ontario and McMaster Universities Arthritis Index (WOMAC) | WOMAC is a patient-reported outcome measure for the assessment of lower limb osteoarthritis | 3 weeks | 
| Physical Activity Scale for the Elderly (PASE) | Physical Activity Scale for the Elderly (PASE) will be used to evaluate the physical activities of individuals. Higher scores show the higher physical activity level. | 3 weeks |
