Effects Of A Home Based Exercise Program Following Total Hip Arthroplasty

Primary outcomes

1. OXFORD HİP SCORE

   Time frame: Prior to surgery, two weeks following surgery, and twelve weeks following surgery, the same measurements will be taken.

   The Oxford Hip Score consists of 12 questions asking patients to describe their hip pain and function during the past 4 weeks. Each item uses a 5-point response scale with values from 0 to 4. An overall score is created by summing the responses to each of the 12 questions. The total score can range from 0 to 48 (most recent scoring system), where 0 is the worst possible score, indicating severe hip problems, and 48 is the best score, suggesting excellent hip function

2. TAMPA SCALE FOR KINESİOPHOBİA

   Time frame: Prior to surgery, two weeks following surgery, and twelve weeks following surgery, the same measurements will be taken.

   It is a scale consisting of 17 questions created to measure fear of injury. The scale includes injury/re-injury and fear-avoidance parameters in work-related activities.A 4-point Likert scoring on the scale (I strongly disagree

   1, I disagree 2, I agree 3, I completely agree 4) is used. Individuals receive a total score between 17-68. A high score on the scale indicates that the person has a high level of kinesiophobia. Scores over 37 points are interpreted as high kinesiophobia.

3. İNTERNATİONAL PHYSİCAL ACTİVİTY QUESTİONAİRE (SHORT FORM)

   Time frame: Prior to surgery, two weeks following surgery, and twelve weeks following surgery, the same measurements will be taken.

   The short form records the activity of four intensity levels: 1) vigorous-intensity activity such as aerobics, 2) moderate-intensity activity such as leisure cycling, 3) walking, and 4) sitting. The original authors recommended the "last 7 day recall" version of the questionaire for physical activity surveillance.

4. JOİNT POSİTİON SENSE ERROR TEST

   Time frame: Prior to surgery, two weeks following surgery, and twelve weeks following surgery, the same measurements will be taken.

   The range of motion in the hip flexion direction is determined to be tested as active movement and passive movement in the 30 ˚, 60 ˚ and 90 ˚ positions. Movement deviations from specified angles are recorded along with the degree of deviation. The joint position sense error increases with the amount of deviation from the anticipated angle.

5. FOUR SQUARE STEP TEST

   Time frame: Prior to surgery, two weeks following surgery, and twelve weeks following surgery, the same measurements will be taken.

   It is a measurement of dynamic standing balance.Performance time is calculated for each individual. Prolonged performances indicate an absence of equilibrium.

6. THE TİMED UP and GO TEST

   Time frame: Prior to surgery, two weeks following surgery, and twelve weeks following surgery, the same measurements will be taken.

   The timed up and go test measures in seconds the time it takes a subject to rise from a chair, walk a distance of 3 meters, turn, walk back to the chair and sit down. This test has been used to examine balance, gait speed, and functional ability that would be required for the performance of basic activities of daily living in older people.

7. Assessment of Hip Muscle Strength

   Time frame: Prior to surgery, two weeks following surgery, and twelve weeks following surgery, the same measurements will be taken.

   A microFET®2 (Digital Hand-held Dynamometer, Hoggan Scientific, LLC; Salt Lake City, Utah) Hand-Held Dynamometer is going to used to measure muscle strength. Using the break test method, which reveals isometric muscle contraction during the muscle test, force is applied in the opposite direction until a joint movement occurred exceeding the maximum power applied with the dynamometer. The strength of the healthy and osteoarthritic hip muscles are evaluated with the patient in supine position. The measurements are recorded as Newton (N) units.

8. Assessment of Hip Joint Range of Motion

   Time frame: Prior to surgery, two weeks following surgery, and twelve weeks following surgery, the same measurements will be taken.

   Individuals' hip joint range of motion will be evaluated using the Baseline Bubble® Inclinometer. Hip flexion and abduction active range of motion will be evaluated in the standing position, and hip rotations will be evaluated in the supine position. Decreased hip joint range of motion is a clinical precursor of hip osteoarthritis, characterized by pain and loss of function.

9. Assessment of Postural Control

   Time frame: Prior to surgery, two weeks following surgery, and twelve weeks following surgery, the same measurements will be taken.

   To evaluate postural control, measurements will be made with a software-based static posturography device (Tetrax®, Sunlight Medical Ltd). Tetrax® consists of four independent platforms that measure vertical pressure changes from both toes and both heels, and a computer software that combines the digital data from this platform. The system can digitally record data from four different measurement platforms in a certain period of time and document it as visual and numerical values. While measuring, individuals place their bare feet on the platforms and stand comfortably in a quiet environment. Individuals hold their head and eyes open and closed. It is evaluated in 8 different positions using neck rotations. The software evaluates postural control by generating a stability index with a numerical value from all measurements.
