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.

  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Cycle Ergometer Group (CEG)
Isometric exercises Transcutaneous electrical nerve stimulation Ultrasound Cycle ergometer
Other: Cycle Ergometer
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.
Device: Transcutaneous electrical nerve stimulation
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.
Other Names:
  • TENS
Device: Ultrasound
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
Other Names:
  • US
Other: Isometric exercises
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
Active Comparator: Control Group
Isometric exercises Transcutaneous electrical nerve stimulation Ultrasound
Device: Transcutaneous electrical nerve stimulation
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.

Other: Isometric exercises
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

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Diapason survey
Time Frame: 3 weeks
Diapason will be used to survey vibration sense to evaluate deep sensation
3 weeks
Digital Goniometer
Time Frame: 3 weeks
Digital Goniometer will be used to measure angle of the knee position to evaluate deep sensation.
3 weeks
6 Minute Walking Test (6MWT)
Time Frame: 3 weeks
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)
Time Frame: 3 weeks
WOMAC is a patient-reported outcome measure for the assessment of lower limb osteoarthritis
3 weeks
Physical Activity Scale for the Elderly (PASE)
Time Frame: 3 weeks
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
