Study summary

The Dolphin 2.0 is a platform that runs an immersive virtual reality software, based on an oceanic environment, where players control simulated creatures (dolphin, orca, axolotl). Video games lead to high levels of motivation and arousal, provide immediate feedback and playback, provide explicit reward and implicit success, and titrate difficulty levels. This encourages the practice of exercise, being an important complement to physiotherapy sessions.

The main goal of this study is to evaluate the feasibility, safety and efficacy of an immersive virtual reality software (Dolphin, 2.0) in Parkinson's disease symptomatic control, in a two-arm, randomized, single-blind (blind rater for primary and secondary outcomes), delayed-start feasibility and efficacy trial.

Study arms

  • Experimental
    Active arm

    The active arm will include 3 days a week of training with the Dolphin 2.0 for 12 consecutive weeks. Each session will have the duration of 60 minutes.

    Device: Dolphin 2.0

  • Active comparator
    Delayed-start control arm

    The delayed-start control arm will have six-weeks of physiotherapy specialized for PD (3 times/week, 60 minutes/session) and six-weeks of 3 days a week of training with the Dolphin 2.0, with sessions of 60 minutes.

    Device: Dolphin 2.0
