Feasibility and Usability of Immersive Virtual Reality Exergames for Patients With Parkinson's Disease: A Pilot Study.
Article in Annals of rehabilitation medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: To evaluate the feasibility, safety, and usability of a novel fully immersive virtual reality (VR) exergame, designed to incorporate cognitive-motor dual-task training for patients with Parkinson's disease (PD).
methodsWe developed a specialized fully immersive VR exergame program, featuring seven cognitive-motor dual-task games. Prior to the pilot study, we refined the system through two successive usability evaluations involving 17 and 15 rehabilitation experts, respectively, to optimize safety and interface design. Subsequently, four patients with idiopathic PD completed a 30-minute VR exergame session using the finalized system under therapist supervision. We assessed cybersickness using the Simulator Sickness Questionnaire (SSQ) and evaluated usability via the User Experience Questionnaire (UEQ) and a self-developed Custom Usability and Satisfaction Survey.
resultsAll participants completed the session without adverse events. Mean SSQ total scores decreased from 14.75±9.43 to 4.75±1.89 without statistical significance (p>0.05). UEQ demonstrated positive experiences, with Attractiveness (1.167), Efficiency (1.063), and Stimulation (1.500) exceeding benchmarks. Custom Usability and Satisfaction Survey scores for interest (6.00/7) and overall satisfaction (6.25/7) were high; however, physical comfort was rated relatively lower (4.25/7) due to the headset weight and safety harness. Conclusion: The developed fully immersive VR exergame system is feasible, safe, and engaging in patients with PD. Limitations include the small sample size and single-session design. Future research should focus on large-scale randomized controlled trials and hardware improvements to enhance physical comfort for long-term clinical application.
