The effects of new technologies, particularly exergames, on the rehabilitation process of patients with hip arthroplasty have not yet been verified. For this reason, the aim of this study is to evaluate the effectiveness, in terms of balance recovery, of a balance rehabilitation program based on serious games in individuals with hip arthroplasty compared to conventional treatment.
Total Hip Arthroplasty (THA) is one of the most commonly performed orthopedic surgeries worldwide, primarily aimed at reducing pain, improving function, and enhancing quality of life. Over the past decade, the rate of THA has increased by 30%, and it is projected to double by 2035. Rehabilitation after THA includes pain management, wound care, self-care, motor therapy, early mobilization, and complication prevention [iv, v, vi]. Active patient involvement in the rehabilitation process is increasingly recognized as essential for improving post-THA autonomy .
Exergames can enhance patient engagement and attention during treatment, potentially leading to better rehabilitation outcomes. The application of game design approaches in rehabilitation has gained popularity, offering more engaging treatments that boost patient motivation and understanding. Serious games, which are not primarily intended for entertainment, focus on specific therapeutic goals. In motor rehabilitation, exergames allow patients to perform physical exercises through video game interaction, often integrating sensors and biosensors that provide biofeedback and enable therapists to monitor progress and personalize treatment.
Despite their growing popularity, there is limited literature on the effectiveness and safety of exergames in orthopedic rehabilitation. A systematic review by Wang et al. found a moderate reduction in pain with technology-assisted rehabilitation (via tele-rehabilitation) in patients with hip and knee arthroplasty, but no significant effects on functional mobility. Research specifically on THA patients is scarce and of low quality. Byra et al. reported similar findings, indicating a lack of comprehensive evidence on the effectiveness of technological rehabilitation in THA patients, although preliminary results in pain management, posture training, and proprioception are promising.
The effects of new technologies, particularly exergames, on the rehabilitation of patients with hip arthroplasty remain unverified. This study aims to evaluate the effectiveness of a balance rehabilitation program based on serious games in individuals with hip arthroplasty compared to conventional treatment.

| Active Comparator: conventional balance rehabilitation without the use of technological devices. | Other | Intervention of the Control Group (CG) consists of 30 minutes (4 days/week, for 4 weeks) of conventional balance rehabilitation treatments without the use of technological devices. The motor exercises will focus on the rehabilitation of balance, the trunk, and the lower limbs and will be carried out with a physiotherapist who will tailor the treatment according to the patient's characteristics and needs. Primary attention will be given to recovering trunk control and seated posture. This phase will focus on restoring and maintaining muscle trophism in the anterior and posterior kinetic chains of the thigh and lower leg, as well as the hip's range of motion, through isometric exercises and gentle joint mobilizations while adhering to anti-dislocation guidelines. The process will continue with the reacquisition of the upright stance, emphasizing proprioceptive, coordination, and balance abilities. Once the upright position is stabilized, gait re-education will be introduced. |

| Day 0 (T0 - baseline), day 30 (T1 - After treatment). |
| Passive Range of Motion (p-ROM) | Passive ROM refers to the movement of a joint through its range of motion by an external force. It's calculated using goniometer. Goniometer measures with a sensitivity of 1 degree. Elevated degrees of p-rom means high joint mobility. | Day 0 (T0 - baseline), day 30 (T1 - After treatment). |
| Ten Meter Walking Test (10MWT) | The 10 Metre Walk Test is a performance measure used to assess walking or gait speed in meters per second over a short distance. It can be employed to determine functional mobility, gait, and vestibular function. Equipment required consists of a walkway of 10m with additional 2m at both ends, marked with tape, for acceleration & deceleration (14 m total). The 14-metre walkway is marked 0-, 2-, 12-, and 14-metre points. In addition is required 2 chairs and stopwatch (or timer). The total time taken to ambulate 10 meters is recorded in this way: timing starts when the toes pass the 2-meter mark and stops when the toes pass the 12-meter mark. The total time is recorded in m/s. Low total time in 10MWT means that gait speed is elevate. | Day 0 (T0 - baseline), day 30 (T1 - After treatment). |
| Hip Dysfunction and Osteoarthritis Outcome Score for Joint Replacement (HOOS JR). | The hip disability and osteoarthritis outcome score (HOOS) is a questionnaire intended to be used to assess patient's opinions about their hip and associated problems and to evaluate their symptoms and functional limitations during a therapeutic process. HOOS JR is developed based on the original 40-question questionnaire HOOS. HOOS JR has 6 items and it is shorter than original HOOS. The HOOS is meant to be used over short and long-term intervals to assess changes over time or the effect of treatment. Factors that should be considered when using the HOOS include age, sex, weight, geographic location, other chronic diseases, history of an inactive hip problem, contralateral hip disease, and active knee, ankle, or foot problems. Each question allows for a score ranging from 0 to 4, where 0 corresponds to the absence of symptoms and 4 corresponds to the most severe symptom. | Day 0 (T0 - baseline), day 30 (T1 - After treatment). |
| Medical Research Council Scale (MRC) | The Medical Research Council Scale (also known as Oxford Scale) is a numerical rating scale used to quantify the power or strength produced by the contraction of a muscle. The main muscle groups investigated are: Ankle Dorsiflexion, Ankle Plantiflexion, Knee Extension, Knee Flexion, Hip Flexion and Hip Extension. Muscle Grading Scores consists in: 0-No detectable muscle contraction (visible or palpation);
| Day 0 (T0 - baseline), day 30 (T1 - After treatment). |
| Modified Barthel Index (mBI) | The Barthel Index for Activities of Daily Living is an ordinal scale which measures a person's ability to complete activities of daily living (ADL). The Barthel Index measures the degree of assistance required by an individual on ten mobility and self-care ADL items. The ten items are scored with a number of points, and then a final score is calculated by summing the points awarded to each functional skill. This allows the examiner to measure a patient's functional disability by quantifying their performance. Scores can be assigned either via direct assessment / observation or from reliable interviews with the patient, family, or staff. Research also suggests that the examiner's "common sense" and clinical experience can be used to assign scores. The higher the score, the more independent the patient is in completing the measured ADLs. Higher scores also indicate the patient is more likely to return home, with varying degrees of assistance, following hospital discharge. | Day 0 (T0 - baseline), day 30 (T1 - After treatment). |
| Visual Analog Scale (VAS) | A Visual Analogue Scale (VAS) is one of the pain rating scales.It is often used in epidemiologic and clinical research to measure the intensity or frequency of various symptoms. From the patient's perspective, this spectrum appears continuous; their pain does not take discrete jumps, as a categorization of none, mild, moderate and severe would suggest. It was to capture this idea of an underlying continuum that the VAS was devised. The pain VAS is a unidimensional measure of pain intensity, used to record patients' pain progression, or compare pain severity between patients with similar conditions. The VAS allows you to assign a value to pain from 1 to 10, where 1 corresponds to no pain and 10 corresponds to the maximum pain perceived by the patient in his life. | Day 0 (T0 - baseline), day 30 (T1 - After treatment) and day 120 (T2 - 3 months after treatment). |
| Activities-specific Balance Confidence scale (ABC). | Activities-specific balance confidence (ABC) scale is a structured questionnaire that measures an individual's confidence during ambulatory activities without falling or experiencing a sense of unsteadiness. It consists of 16 questions gauging the individual's confidence while doing activities. The ABC scale is reported to be an accurate measure to identify individuals with a fall risk in populations of stroke, multiple sclerosis, Parkinson's, vestibular disorders, in elderly, and in other neurological conditions that can affect balance. Its a 16-item questionnaire where patients' rate their confidence while doing activities with a scoring from 0-100 (0 is no confidence and 100 is full confidence). | Day 0 (T0 - baseline), day 30 (T1 - After treatment) and day 120 (T2 - 3 Months after treatment). |
The circumference of the thigh of both legs is measured. The measurement is taken at the root of the thigh, that is, approximately 1 cm below the gluteal fold. |
| Day 0 (T0 - baseline), day 30 (T1 - After treatment) and day 120 (T2 - 3 months after treatment). |
| Client satisfaction questionnaire . | The Client satisfaction questionnaire investigates the subject's overall satisfaction with participating in the study. It consists of six questions with a score ranging from 0 to 4. A high score corresponds to a high level of satisfaction from the subject. | Day 30 (T1 - After treatment). |
| Posturography | Posturography (or stabilometry) is an examination that allows for the assessment and measurement of fine postural control. The examined subject stands on a computerized and sensorized platform, remaining still in an upright position. The recording lasts 30 seconds and is repeated twice with eyes open and arms at the sides, and twice with eyes closed and arms at the sides. | Day 0 (T0 - baseline), day 30 (T1 - After treatment). |
