Mechanical Traction Force and Knee Joint Space

Not Applicable

Completed

• Conditions: Knee Arthritis
• Interventions: Device: mechanical traction for knee joint

• Registration Number: NCT05699733
• Lead Sponsor: University of Hail

Brief Summary

the purposes of this crossover study are to Purpose

1. To determine the most effective traction force for knee joint that can be used in the treatment of patients with KOA.

2. To determine the influence of knee joint traction on ROM ok knee joint flexion and extension

3. 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.

Arm && Interventions

Group	Intervention	Description
Mechanical traction force 30% of body weight	mechanical traction for knee joint	will receive continuous mechanical traction from semi flexed knee, for 30 minutes using 30% of the body weight as a traction force
Mechanical traction force 10% of body weight	mechanical traction for knee joint	will receive continuous mechanical traction from semi flexed knee, for 30 minutes using 10 % of the body weight as a traction force
Mechanical traction force 20% of body weight	mechanical traction for knee joint	will receive continuous mechanical traction from semi flexed knee, for 30 minutes using 20% of the body weight as a traction force

Primary Outcome Measures

Name	Time	Method
knee joint space	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

Secondary Outcome Measures

Name	Time	Method
hamstrings flexibility	short term (30 minutes after the first session)	using the Sit and reach test: The Sit and reach test is one of the linear flexibility tests which helps to measure the extensibility of the hamstrings and lower back. it is also a field test which is easy to administer in a community setting with a large scale of population size
knee active range of motion	short term (30 minutes after the first session)	Bubble inclinometer will be used to assess the active knee joint flexion range. Participant will assume supine position and after proper placement of the goniometer, she will be asked to bend her knee and hip joints as much as possible
