Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The treatment sessions consisted of 10 sessions of 60 minutes each, 3 times a week and "one-on-one face-to-face", which consisted of: 10 minutes of warm wet compress in the area involved in total hip arthroplasty to 40oC , 10 minutes of static bicycle for patient tolerance (60% of the reserve of heart rate according to karvonen), 15 minutes of muscular strengthening exercises in which worked for the gluteus medius and greater in lateral decubitus with the leg flexed and extend them in both lower extremities, supine exercises called "bridge" and the work of abductors and adductors of the hip with different resistances depending on the patient's tolerance, together with these 10 minutes of gait training which consists in relearning the phases of the march in parallel bars. In addition to this, a 10-minute work on the Wii Board platform was applied to the experimental group, with the Wii Fit Plus videogame, specifically with the "Loose String" games, where the subject simulates a walk through a rope, tilting the body to the right and left alternately, and "Rio Abajo", game where the subject must move its center of gravity through both lower extremities on the Wii platform, with the aim of reaching a certain objective. All the intervention will be supervised by the physiotherapist, who will administer all the elements of the intervention.

However, the control group did not perform training on the Wii platform.

allocation involved contacting the holder of the allocation schedule who was "off-site" or at central administration site.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using procedures like coin-tossing and dice-rolling

Statistical methods / analysis
Taking into account the study by Beaupré et al. in which they used a conventional physiotherapeutic treatment similar to our study, we established a difference of at least 11.9 points as the minimum clinically important difference
in the WOMAC questionnaire functionality. Therefore this data was taken to make our sample size calculation. It was found that for alpha= 0.05 (probability of committing type I error) and a statistical power of 80%; To detect a minimum difference of 11.9 points in the functionality items of the WOMAC questionnaire, with a minimum effect of 0.08, 35 patients are needed for each study group, ie a total of 70 patients to configure the sample of this study. In agreement with this, the authors of the present study have proposed as experimental hypothesis that there is a decrease of at least 11.9 points in the WOMAC questionnaire in the function item in the group treated with an exercise program that includes virtual reality compared to a conventional treatment.

Summary
Brief summary
After total hip arthroplasty, alterations in muscle function can be evidenced, highlighting decreased muscle torque capacity, decreased balance in the subject, pain and functional impotence. Which affects the ability of the subject to perform their activities of daily life, decreasing independence and function. Subsequent rehabilitation plays an essential role in the recovery of these subjects, however, the use of virtual reality as a additional technique to conventional training has not been evidenced in the literature. Virtual reality has shown benefits in the treatment of hemiplegic patients after the cerebrovascular accident (CVA) in terms of postural control, as well as significant improvements in dynamic balance in patients with chronic stroke. Other studies show that virtual reality contributes significantly to improve balance and functionality in older adults. Therefore, the objective of this study is to show whether adding the use of virtual reality through the Nintendo Wii platform shows improvements in the functionality of subjects with total hip arthroplasty.
