Comparison of Efficiency of Closed Kinetic Chain Exercises Versus Proprioceptive Exercises Patient With Hemophilia

Hemophilia is a bleeding disorder caused by a deficiency of clotting factors in the blood. Muscle and joint bleeding are frequently observed in patients with hemophilia. Lower extremity bleeding can adversely affect balance, gait, and proprioception. The goal of this study; To compare the effectiveness of closed kinetic chain exercises and proprioceptive exercises on balance, proprioception and gait parameters in adolescent and young hemophilic individuals with lower extremity joint involvement.

The main question it aims to answer is:

Are the effects of closed kinetic chain exercises and proprioceptive exercises different on balance and walking in hemophilic individuals?

Primary outcomes

  1. Medio-lateral and Anterior-posterior stability index

    Time frame: 12 weeks

    Represents fluctuations from the horizontal around the mediolateral axis. Mediolateral sway and anterior-posterior stability will record in the double-leg stance for 20 seconds with Biodex Balance System. The feet are placed in a comfortable position for patients, and the center of gravity was recorded in the system to begin the test. Each test will repeat 3 times. A higher sway index indicates a decrease in postural stability.

  2. walking speed

    Time frame: 12 weeks

    A 10-meter walking test will be used to evaluate walking.

  3. Hemophilia joint health score

    Time frame: 12 weeks

    The HJHS is derived from a physical examination of the index joints by a health care professional who should have training and expertise in the conduct of a detailed musculoskeletal (MSK) examination. It is a measure of joint health and sits within the World . The current HJHS version 2.1 comprises an assessment of specific features, or items, of the six index joints and an assessment of global gait. For each of the six joints, the following items are scored: swelling (scored 0-3), duration of swelling (0-1), muscle atrophy (0-2), crepitus on motion (0-2), flexion loss (0-3), extension loss (0-3), joint pain (0-2), and strength (0-4). The maximum score for an individual index joint is 20. Gait is scored 0 to 4. The maximum HJHS total score is 124, with a higher score indicating worse joint health.

Secondary outcomes

  1. Single leg stance test

    Time frame: 12 weeks

    The Single leg stance test (SLTS) measures static balance by challenging participants to stand unassisted on 1 leg. İndividuals stand for 30 or 45 seconds with their arms crossed across their chest or with their hands touching their hips. The SLST will completed with or without shoes and using the dominant or nondominant leg.

    The SLST will completed first with eyes open and then with eyes closed. Participants are timed as soon as their foot leaves the floor and stops once the foot touches the ground, the supporting foot shifts, their suspended foot touches the supporting leg, their eyes open in the eyes-closed trials, an arm is uncrossed or stops touching their hip, or if the maximum allotted time is reached.

    Three trials per condition are recorded, and either an average is calculated or the longest time is used. The SLST performance is reported in seconds (continuous) and requires a stopwatch.

  2. Proprioception

    Time frame: 12 weeks

    A digital goniometer will be used to evaluate proprioception. The patient will be evaluated in a sitting position with eyes closed and open.

  3. 2-dimensional video-based gait kinematic analysis

    Time frame: 12 weeks

    2-dimensional video-based gait kinematic analysis is a simple, practical and inexpensive method in which a colour camera and passive markers are used. Firstly, the fifth metatarsophalangeal joint, the lateral malleolus, the lateral femoral condyle, and the trochanter major will marked as anatomical landmarks. Thereafter, passive markers will attached with double-sided adhesive tapes on the skin. Video recordswere then obtained with a high-speed 2D video camera. The camera will located on the tripod at a distance of 1.5 m from the patient, 0.86 m above the ground and with its optical axis perpendicular to the patients' sagittal axis. The patient will be asked to walk at a normal pace in front of the camera. The 2D records will processed using the Kinovea (version .8.15, Kinovea Open Source Project), which is a free 2D motion analysis will evaluate GKP. During the phases (midstance, preswing, midswing, and late swing phases) requiring a maximal ROMin the knee and ankle joints, kinematic
