Investigating Postural Parameters in Different Hip Pathologies

The postures of the participants will be evaluated using the 4-DIERS. In this method, white light lines (raster lines) are projected onto the participants' backs, and the curvature of these lines is used to create a 3D shape of the back. The patterns formed by these curved lines are detected by the camera. With the help of the software, the detected convex and concave regions allow for the immediate determination of anatomical landmarks and fixed points. A mathematical algorithm is used to reconstruct a three-dimensional model of the spine.

The pain threshold evaluation with an algometer is a method used to assess an individual's sensitivity to pressure-induced pain. An algometer is a device that applies gradually increasing pressure to a specific point on the body until the subject perceives pain. This measurement is referred to as the pressure pain threshold (PPT) and is widely used in clinical and research settings to evaluate pain sensitivity in conditions such as musculoskeletal disorders, fibromyalgia, and chronic pain syndromes.

Pain threshold values are typically recorded in kilograms per square centimeter (kg/cm²) or Newtons (N). The minimum pain threshold represents the lowest pressure at which pain is first perceived, while the maximum pain threshold indicates the highest tolerated pressure before withdrawal. The mean PPT is calculated based on multiple measurements at different anatomical sites to provide a more reliable assessment of an individual's pain sensitivity. Lower pain threshold values suggest high

The Visual Analog Scale (VAS) is a widely used tool for assessing pain intensity and other subjective experiences, such as fatigue or discomfort. It consists of a 10-centimeter (100 mm) horizontal or vertical line, with endpoints representing "no pain" (0) on the left and "worst imaginable pain" (10 or 100) on the right. Patients mark a point on the line that best reflects their perceived pain intensity.

The minimum VAS score is 0, indicating no pain, while the maximum score is 10 (or 100, depending on scaling), representing severe or unbearable pain. The mean VAS score is often calculated in studies to determine the average pain level within a group of patients. The scale is simple, quick to administer, and highly effective in capturing pain variations over time, making it a valuable tool in clinical practice and research for monitoring pain management and treatment outcomes.

The Lafayette Manual Muscle Dynamometer (Lafayette MMD) is a handheld device used to measure muscle strength in various muscle groups. It provides objective, quantifiable data on muscle force production, making it useful in rehabilitation, sports science, and clinical assessments of neuromuscular conditions. The device applies resistance to a specific muscle or muscle group while recording the maximum isometric force exerted by the patient.

Muscle strength measurements with the Lafayette MMD are typically recorded in kilograms (kg) or Newtons (N). The minimum strength value represents the lowest recorded force, while the maximum strength value is the highest force exerted by the muscle during testing. The mean strength value is calculated to provide an overall assessment of muscle function. Higher values indicate greater muscle strength, whereas lower values may suggest muscle weakness or impairment, which is particularly relevant for patients undergoing rehabilitation or recovering

The Harris Hip Score (HHS) is a clinician-based outcome measure used to assess the function, pain, and range of motion in patients undergoing hip surgery or suffering from hip disorders. The total score ranges from 0 to 100, with higher scores indicating better hip function. The HHS includes four main components: pain (44 points), function (47 points), absence of deformity (4 points), and range of motion (5 points). A score of 90-100 is considered excellent, 80-89 good, 70-79 fair, and below 70 poor.

The Hip Outcome Score (HOS) is a patient-reported outcome measure designed primarily for younger, active individuals, especially those undergoing hip arthroscopy. It consists of two subscales: the Activities of Daily Living (ADL) subscale (17 items) and the Sports subscale (9 items). Each item is scored on a 0 to 4 scale, with 0 representing an inability to perform the activity and 4 indicating no difficulty. The total score is calculated as a percentage, with 100% representing the best possible function. The HOS is particularly useful for assessing hip function in active populations and tracking progress after surgical or non-surgical interventions.

The SENSAMOVE Balance Device is an advanced tool used for assessing and training balance, stability, and postural control. It utilizes sensor technology to provide real-time feedback on body movements, making it particularly useful in rehabilitation, sports training, and clinical assessments. The device measures shifts in weight distribution and postural sway, helping individuals improve their coordination and stability through targeted exercises.

The balance performance scores from the SENSAMOVE device vary depending on the specific test protocols used. Typically, the device records minimum, maximum, and mean balance scores, which indicate the user's ability to maintain stability during different tasks. Higher scores generally reflect better balance control, whereas lower scores indicate greater postural instability.

The SF-36 Quality of Life Scale (SF-36) is a widely used patient-reported outcome measure that assesses overall health and well-being across multiple dimensions. It consists of 36 items grouped into eight health domains: physical functioning, role limitations due to physical health, bodily pain, general health perceptions, vitality, social functioning, role limitations due to emotional problems, and mental health. These domains collectively provide a comprehensive assessment of an individual's physical and mental health status.

Each domain of the SF-36 is scored on a 0 to 100 scale, with higher scores indicating better health and quality of life. In addition to the individual domain scores, the SF-36 can also generate two summary scores: the Physical Component Summary (PCS) and the Mental Component Summary (MCS), which provide an overall view of physical and mental well-being. The mean scores vary across different populations and health conditions, but in general, a score closer to 1

The Waterloo Handedness and Footedness Questionnaire is a self-reported measure designed to assess an individual's preference for hand and foot usage in various tasks. It evaluates laterality by determining the degree to which a person favors one hand or foot over the other in everyday activities. The questionnaire consists of two separate sections, one for hand preference and another for foot preference, each containing multiple items that require individuals to indicate their preferred limb for specific tasks.

The total scores for handedness and footedness range from -100 to +100, where -100 represents strong left-hand or left-foot preference, 0 indicates no preference (ambidextrous), and +100 signifies strong right-hand or right-foot preference. The mean scores vary based on population norms, but typically, a strong preference for either the left or right side results in scores closer to the respective extreme values. This questionnaire is commonly used in research on laterality,
