      <textblock>
        This project is structured in two distinct phases. The first phase deals with the recovery of&#xD;
        the hip fracture in the acute phase up to ambulation, and the second is understood as the&#xD;
        continuation of functional improvement of gait. In the first phase, the aim is to evaluate&#xD;
        the effects of the use of the robotic device (SWalker) on the physical improvement of the&#xD;
        patient. While in the second phase, the objective is to evaluate the effects of virtual&#xD;
        reality technology combined with the use of the SWalker.Therefore, the following specific&#xD;
        objectives are identified:&#xD;
  &#xD;
          -  Phase I: To analyze the effects of SWalker application in patients with acute hip&#xD;
             fracture on clinical parameters of rehabilitation.&#xD;
  &#xD;
          -  Phase II: To study the effects of the application of the SWalker combined with immersive&#xD;
             technology in people with impaired gait function after hip fracture.&#xD;

        In the preliminary phase, the usability and acceptance of the SWalker II system combined with&#xD;
        virtual reality is evaluated with a group of healthy subjects. For this purpose, an exposure&#xD;
        session and the evaluation of the system based on questionnaires are carried out. On the&#xD;
        other hand, a gait characterization session (capture of ROM and EMG) is performed inside and&#xD;
        outside the walker with different speeds and weight loads.&#xD;
  &#xD;
        In the first phase of the clinical study, patients with hip fractures in the early&#xD;
        rehabilitation phase were recruited. They are randomly assigned to a control group or&#xD;
        experiment group. And for a period of 6 weeks, both groups carry out the same rehabilitation&#xD;
        exercise program based on strength, balance and ambulation exercise. The difference is that&#xD;
        the experimental group performs the rehabilitation exercises with the SWalker, and the&#xD;
        control group performs these exercises with conventional parallel bars.&#xD;
  &#xD;
        In the second phase of the clinical study, these same patients who have passed the first&#xD;
        pass, move on to a 6-weeks program of maintenance and improvement of gait function. Again,&#xD;
        they are divided into 2 groups, control and experimental. So the control group will perform&#xD;
        walking exercises with the Swalker and conventional balance exercises and the experimental&#xD;
        group will perform walking and balance exercises with SWalker and virtual reality.&#xD;

        objectives are identified:
  
          -  Phase I: To analyze the effects of SWalker application in patients with acute hip
             fracture on clinical parameters of rehabilitation.
  
          -  Phase II: To study the effects of the application of the SWalker combined with immersive
             technology in people with impaired gait function after hip fracture.
  In the preliminary phase, the usability and acceptance of the SWalker II system combined with
        virtual reality is evaluated with a group of healthy subjects. For this purpose, an exposure
        session and the evaluation of the system based on questionnaires are carried out. On the
        other hand, a gait characterization session (capture of ROM and EMG) is performed inside and
        outside the walker with different speeds and weight loads.
  
        In the first phase of the clinical study, patients with hip fractures in the early
        rehabilitation phase were recruited. They are randomly assigned to a control group or
        experiment group. And for a period of 6 weeks, both groups carry out the same rehabilitation
        exercise program based on strength, balance and ambulation exercise. The difference is that
        the experimental group performs the rehabilitation exercises with the SWalker, and the
        control group performs these exercises with conventional parallel bars.
  
        In the second phase of the clinical study, these same patients who have passed the first
        pass, move on to a 6-weeks program of maintenance and improvement of gait function. Again,
        they are divided into 2 groups, control and experimental. So the control group will perform
        walking exercises with the Swalker and conventional balance exercises and the experimental
        group will perform walking and balance exercises with SWalker and virtual reality.

Nausea-related subscore (N), Oculomotorrelated subscore (O), Disorientation-related subscore (D) are the scores for the symptoms for the specific aspects. Total Score (TS) is the score representing the overall severity of cybersickness experienced by the users of virtual reality systems. It is suggested that total scores can be associated with negligible (< 5), minimal (5 - 10), significant (10 - 15), and concerning (15 - 20) symptoms. A simulator resulting in total scores above 20 is considered "bad".
