NCT03532152

Brief Summary

The study assess the effect of the VR technology (Pure Purr technology) on the recovery of the autonomic nervous system in healthy volunteers affected by moderate stress. Study subject randomized into two groups: in Group 1 volunteers first be tested with the VR headset A, and during the next visit- headset B. Group 2 volunteers first be tested with the VR headset B, and during the next visit- headset A. Before, after and during VR session was conducted stress modulation and ECG recording. The Pure Purr technology combines several audio and visual stimuli aimed at activation of the parasympathetic nervous system. Therefore, this study will investigate the effect of this technology on the recovery of autonomic nervous system performance after moderate stress.

Outcome Measures

Primary Outcomes (1)

  • Power in high frequency range (HF) [ms2]

    Change from Power in high frequency range (HF) \[ms2\] at 5 minutes before and after VR technology using

    The outcome measure will be assessed between two visits with minimum interval 24 up to seven days

Secondary Outcomes (7)

  • The square root of the mean of the sum of the squares of differences between adjacent NN intervals (rMSSD), [ms]

    The outcome measure will be assessed between two visits with minimum interval 24 up to seven days

  • Standard deviation of all NN intervals (SDNN), [ms]

    The outcome measure will be assessed between two visits with minimum interval 24 up to seven days

  • Ratio Power in low frequency range [ms2]/ Power in high frequency range [ms2] (Ratio LF [ms2]/HF [ms2])

    The outcome measure will be assessed between two visits with minimum interval 24 up to seven days

  • Total power (TP), [ms2]

    The outcome measure will be assessed between two visits with minimum interval 24 up to seven days

  • Heart Rate (HR) variable.

    The outcome measure will be assessed between two visits with minimum interval 24 up to seven days

  • +2 more secondary outcomes

Study Arms (2)

Pure Purr VR technology

ACTIVE COMPARATOR

The arm will use the virtual reality headset reproduces a dynamic video content that is visually perceived with the help of the high-resolution screen. The total length of the audio-video sequence is 6 minutes 11 seconds, of which 1 minute 11 seconds is the Pure Purr promotional video, and the duration of the investigational audio-visual sequence itself is 5 minutes.

Device: Pure Purr VR technology

Sham VR technology

SHAM COMPARATOR

The arm will use the headset with audio-visual sequence is similar to the one in the investigational version of the software. The key difference is that the audio sequence has not been modified with the binaural effect and has not been synchronized with the tact of respiratory movements and the frequency of heart rate. The total length of the audio-video sequence is 6 minutes 11 seconds, of which 1 minute 11 seconds is the Pure Purr promotional video, and the duration of the investigational audio-visual sequence itself is 5 minutes.

Device: Sham VR technology

Interventions

The Pure Purr technology consists of BoboVR X1 headset with pre-installed software. The virtual reality headset reproduces a dynamic video content that is visually perceived with the help of the high-resolution screen. Also, the headset is able to play audio and transmit it via the headphones. The audio sequence has been modified by adding a binaural effect and has been synchronized with the tact of respiratory movements and the frequency of heart rate.

Pure Purr VR technology

The sham technology includes an identical BoboVR X1 virtual reality headset with pre-installed software. The audio-visual sequence is similar to the one in the investigational version of the software. The key difference is that the audio sequence has not been modified with the binaural effect and has not been synchronized with the tact of respiratory movements and the frequency of heart rate.
