Telerehabilitation as an Alternative to Face-to-Face Rehabilitation After Total Hip Arthroplasty

Functional level was assessed using the Western Ontario McMaster University Osteoarthritis Index. Western Ontario and McMaster Universities Osteoarthritis Index consists of 24 questions and 3 subcategories (pain, stiffness and physical function). Pain is evaluated with 5 questions, stiffness with 2 questions and physical function with 17 questions. Each question in the Index is scored from 0 (none) to 4 (very severe, very difficult). The total score can be a minimum of 0 and a maximum of 100. In addition, each subcategory can also be evaluated on its own. A higher score on the Index indicates more symptoms and physical disability.

Pain intensity was assessed using the pain subcategory of Western Ontario McMaster University Osteoarthritis Index and the Visual Analog Scale. There are 5 questions in the pain subcategory of the Western Ontario and McMaster Universities Osteoarthritis Index. Each question in the Index is scored from 0 (none) to 4 (very severe, very difficult). The pain score can be a minimum of 0 and a maximum of 20. A higher pain score indicates more pain. Visual Analog Scale consists of a horizontal 10 cm straight line. When viewed from left to right, there is a value of 0 at the beginning and 10 at the end of the line. The 0 point of the line indicates no pain and the 10 point indicates the most severe pain felt in life.

Quality of life will be assessed with the EQ-5D General Quality of Life Questionnaire. The first part of the questionnaire consists of questions related to five different areas of health, including mobility, personal care, usual activities, pain/discomfort, and anxiety/depression. Each question is rated on a three-point scale as 'no problem, some problem and major problem'. Therefore, the questionnaire generates 243 different results. As a result of the scoring, a score between -0.59 and 1 is obtained and 0 indicates death, 1 indicates full health, minus values indicate unconsciousness, etc. The second part of the questionnaire shows the score that the person gives to the health status by marking on a vertical ruler or a thermometer-like visual analogue scale between 0 and 100. A score of 100 indicates the healthiest state.

Locomotor performance was assessed with the stair climb test. Stair Climb Test: The time taken to ascend and then descend a 9-step staircase was recorded as the patient's score.

Lower extremity muscle strength will be assessed with the a hand dynamometer. Hand Dynamometer: Hip muscles (flexors, extensors, abductors and adductors) and knee extensors will be evaluated using a hand dynamometer (Commander Muscle Tester, JTech, USA). 3 consecutive maximum isometric contraction measurements at 1 minute intervals will be averaged.

Range of Motion (ROM) will be evaluated by goniometric measurement.
