Study Overview
Brief Summary
the purposes of this crossover study are to Purpose
- To determine the most effective traction force for knee joint that can be used in the treatment of patients with KOA.
- To determine the influence of knee joint traction on ROM ok knee joint flexion and extension
- To determine the influence of knee joint traction on the flexibility of hamstring muscles
Detailed Description
this study is a pilot study design aiming to determine the most effective mechanical traction force used for knee joint treatment. this effectiveness was assessed in favor of the separation of the joint surfaces in cm in addition to the hamstring flexibility measured in cm and active knee flexion range of motion.
according to previous literature, there is no consensus regarding the most appropriate traction force that can produce statistical and clinically meaningful differences so we started this pilot study.
the results of this study will be used to conduct a larger-scale study using the most appropriate traction force on patients having knee osteoarthritis.

Outcomes
Primary Outcomes
knee joint space
Time Frame: short term (30 minutes after the first session)
the distance in millimeters will be measured between the articilar acriliges of femur and tibia in non-weight bearing position from the medial and lateral aspects of the knee joint using ultrasonography device designed to assess musculoskeletal conditions
knee joint space
Time Frame: immediate (after first session)
the distance in millimeters will be measured between the articilar acriliges of femur and tibia in non-weight bearing position from the medial and lateral aspects of the knee joint using ultrasonography device designed to assess musculoskeletal conditions
Secondary Outcomes
- hamstrings flexibility(short term (30 minutes after the first session))
- knee active range of motion(short term (30 minutes after the first session))
- hamstrings flexibility(immediate (after first session))
- knee active range of motion(immediate (after first session))
