Clinical Trial Summary

Prospective, controlled, randomized, non-masked longitudinal research project for the realization of a doctoral thesis, based on an intervention with virtual reality in order to assess whether the influence on balance and the oculomotor muscles is positive.

The introduction of new technologies in the field of medicine in all fields, and in particular the rehabilitation is fully in place and under development. There are numerous examples like these technologies, including virtual reality (VR), have helped different health fields such as surgery or physiotherapy.

The main aim of the study is to analyze these factors and analyze the way in which virtual reality (VR) can modulate the convergence of the gaze and can influence the center of pressure (COP). As secondary objectives es proposes to analyze the interrelationship between the VR and the COP to analyze the clinical possibilities of application in the field of rehabilitation, whether due to a downward (oculomotor) or upward alteration (COP alteration), as well as if physical activity or gender can also influence.

Description:

The center of pressure (COP) is the point where the resultant of the ground reaction forces is applied to the base of support. The oscillation of the individual with respect to the ground is projected in an anteroposterior line (AP) and another mediolateral (ML). With these two parameters you can define the total route covered by the COP. The population general presents a small area: parameters of short distance and fast and precise displacements. An alteration of the balance can be objectified by measuring an increase in the same area; reflecting a loss of axis control AP and ML and a slowing in the perception of this loss.

The oculomotor muscles are responsible for maintaining horizontal gaze; given the position bipedal, the brain seeks to maintain this premise to allow carrying out the usual activities in it position A good response of this musculature, specifically, the ability to accommodate the convergence of the look, will guarantee optimal function.

Intervention

Device:
• Virtual Reality game
The game consists of cutting mobile targets, using lightsabers while avoiding obstacles that approach the user. This game is a reference for immersive play since, while distracting, it recreates a physical activity similar to what would be done in reality. It has been shown that the same energy expenditure, on the part of the user, practicing tennis in real life, is what he does playing "Beat Saber" playing the same period of time.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from Baseline Centre Of Pressure at 7 days after 12th session	The pressure center (COP) is the point where the resulting reaction forces with the ground is applied to the support base. The oscillation of the individual with respect to the ground is projected in an anteroposterior line (AP) and a mediolateral line (ML). With these two parameters, the total route covered by the COP can be defined. An alteration of balance can be objectified by measuring an increase in the same area; reflecting a loss of control of the AP and ML axes and a slowdown in the perception of this loss.	Day 1 and 7 days after the 12th session.
Secondary	Change from Baseline PPC at 7 days after 12th session	The Near Convergence Point (PPC) test analyzes the effectiveness of the oculomotor muscles, consists of showing a stimulus 40 centimeters from the participant, a point where the vision of this stimulus should not be double. The stimulus will approach until the participant sees double, it is the breaking point and it will be the PPC to be measured.	Day 1 and 7 days after the 12th session.
