Introduction: The Parkinson is one of the most common degenerative diseases of the central nervous system , mainly characterized by resting tremor , rigidity, akinesia and postural instability , also featuring the autonomic modulation of heart rate , which can lead to reduced frequency variability heart . Some activities may modify the modulation , including rehabilitation using virtual reality. Method: The research is interventional type , quantity and prospective, where volunteers were chosen for inclusion and exclusion criteria and divided into two groups , Control and Parkinson's, where they underwent 24 sections with virtual reality physiotherapy three times a week . Analysis of the autonomic modulation of heart rate was performed before and after the rehabilitation program with the frequency meter Polar brand. Statistical analysis was performed in 5.2 Biostat program with Shapiro- Wilk test to verify the normality , followed by t test to compare the data.

To verify that the baseline conditions were adequate for the start of the collection, the volunteer remained 15 minutes at rest in supine position . They were measured and recorded : blood pressure by auscultation , using a mercury sphygmomanometer and a stethoscope ; and heart rate at rest by a heart rate monitor , with all measures carried out by the same researcher . Then the volunteer remained in the same position and was initiated to collect data with the registration of iR -R by Polar heart rate monitor model RS800CX (Polar Electro Co.Ltda . Kempele , Finland ) for 15 min. During the registration time, the participants maintained spontaneous respiration , were told not to talk , not sleep and avoid sudden movements . Subsequently , the recorded iR - R were transferred via an interface to a computer compatible for Polar softwere , the data being further processed into .txt format.

For the analysis we used the Kubius HRV Analysis Version 2.0 software (Kuopio, Finland). From the choice of the most stable stretch of five minutes, HRV was analyzed in the time domain (TD) and the variables selected the RR interval, the square root square mean difference between normal adjacent iR-R expressed in milliseconds (RMSSD) and SDNN, in the frequency domain via LF, HF and LF / HF addition to the non-linear analysis with the contents SD1, SD2 and Shannon Entropy.

To carry out the treatment with virtual reality Xbox 360® video game was the (Microsoft) used, the KinectTM Sensor, the kinectTM Adventures !, games with 6 modes and different phases and kinectTM Sports: Ultimate collection with 8 sports and different phases and TV Philips® the mark of 42 inches. The selected games were only the balance category, attention and planning, which consists of ten games, but only eight were used, including Kinect Sports game - "Tennis", "golf", "Ski" and the Kinect Adventure - "space bubble", "rapids", "top of the reflexes," "Hall of ricochets" and "leaks".

Before the first virtual training session , the presentation of the goals of each of the games and an adaptation session was held , where the therapists were next to the volunteer performing verbal commands . During the Games volunteers remained in the standing position and barefoot .

The volunteers performed 24 sessions in pairs, supervised by researchers for three times a week , every other day , lasting an hour each session. The scheduling range of care was organized so that the GP volunteers were always trained in the ON period of medication.
