Virtual Reality Table Tennis for Parkinson’s: First Randomized Trial

Parkinson’s disease destroys the neurons that produce dopamine, causing tremors, slow movement, rigidity, and balance problems. While medication remains the primary treatment, physical therapy is increasingly important for maintaining mobility and independence. A 2026 pilot randomized controlled trial from Japan is the first to test whether virtual reality table tennis could enhance rehabilitation for Parkinson’s patients.

The Study Design

The trial, published in Neurologia i Neurochirurgia Polska by Fujioka and colleagues, was conducted at Murakami Karindoh Hospital in Japan between December 2022 and March 2023. The design was prospective and randomized, with 10 Parkinson’s patients completing the intervention. Half received VR-based table tennis training using the Oculus Quest 2 headset and Eleven Table Tennis software, replacing the physiotherapy component of multimodal rehabilitation. The control group received conventional multimodal rehabilitation with physiotherapy, occupational therapy, and speech therapy. Both groups trained twice weekly for 8 weeks.

The VR table tennis intervention used the Oculus Quest 2, a standalone VR headset that requires no external tracking stations or computer connection. The Eleven Table Tennis software provides a realistic table tennis simulation with physics-based ball behavior, spin, and trajectory prediction. The intervention replaced only the physiotherapy component, with all participants continuing conventional occupational therapy and speech therapy.

Primary Finding: No Motor Symptom Superiority

The primary outcome was motor symptom severity measured by the Movement Disorder Society Unified Parkinson’s Disease Rating Scale Part III (MDS-UPDRS Part III). The results showed no statistically significant difference between groups after the 8-week intervention. The p-value was 0.059, just missing conventional significance. The effect size (Hedges’ g) was -1.02, indicating greater reduction in motor symptom scores in the control group that received conventional therapy rather than VR table tennis.

This finding matters because it shows that VR table tennis did not harm motor symptoms compared to established rehabilitation. The VR group maintained motor function while engaging in a novel, game-like intervention that might improve adherence to rehabilitation programs.

Secondary Outcomes: Directional Trends Favor VR

While the primary outcome did not show superiority, several exploratory secondary outcomes showed directional trends favoring the VR group:

• Comfortable walking time (10-meter test): Hedges’ g = 0.82
• Comfortable walking steps (10-meter test): Hedges’ g = 1.06
• Maximum walking speed (10-meter test): Hedges’ g = 0.72
• Maximum walking steps (10-meter test): Hedges’ g = 0.78
• Quiet-standing sway area (balance): Hedges’ g = 0.44
• Quality of life (PDQ-8): Hedges’ g = 0.59

None of these outcomes reached statistical significance, likely due to the very small sample size. However, the consistent pattern of positive effect sizes across gait, balance, and quality of life measures suggests that immersive VR training may influence functional outcomes in some Parkinson’s patients.

Effect sizes above 0.8 are typically considered large. The 1.06 effect size for comfortable walking steps and 0.82 for comfortable walking time suggest that VR table tennis may produce clinically meaningful improvements in gait efficiency, even if statistical significance was not achieved in this pilot study.

Why VR Table Tennis Makes Biological Sense

The game-like and interactive nature of VR table tennis may enhance rehabilitation through several mechanisms. VR provides real-time feedback on ball trajectory, spin, and timing, allowing patients to adjust movements with immediate visual confirmation. This feedback loop reinforces motor learning, which is often impaired in Parkinson’s disease.

VR table tennis requires repeated practice of visuomotor coordination, anticipatory postural adjustment, and dynamic weight shifting. These are exactly the functions that deteriorate in Parkinson’s. The immersive nature of VR may also increase engagement and adherence compared to conventional physiotherapy exercises, which patients often perceive as monotonous or boring.

Quality of life in Parkinson’s disease is influenced not only by motor symptoms but also by motivation, activity limitation, and adherence to rehabilitation. The favorable trend observed in PDQ-8 scores may reflect broader effects of engagement with rehabilitation rather than direct motor improvement alone.

Safety and Tolerability

Regarding safety, no serious adverse events directly related to the VR intervention were observed. No falls, severe vertigo, or balance deterioration occurred during supervised VR sessions. No participant developed cybersickness requiring medical treatment. However, one participant had difficulty performing VR-based rehabilitation, and another discontinued because the intervention was unsuitable.

These findings suggest that VR-based rehabilitation may be feasible for some patients with Parkinson’s disease, but careful patient selection and monitoring are necessary. Not all Parkinson’s patients will tolerate or benefit from VR training, especially those with severe balance impairment or cognitive decline.

Context With Existing Research

This pilot study adds to a growing body of evidence on table tennis for Parkinson’s rehabilitation. A 2026 meta-analysis by Li and colleagues, published in Healthcare (Basel), pooled 14 randomized controlled trials totaling 1,565 participants and found that table tennis produces a standardized mean difference of 0.78 for motor function improvements and 2.05 for cognitive function across neurodegenerative populations. These are very large effect sizes.

A 2025 clinical review by Khalid and Khalid in Cureus confirmed that table tennis improves motor control, cognitive function, and psychosocial well-being in Parkinson’s disease patients. A 2016 Cochrane review by Dockx and colleagues found that VR for rehabilitation in Parkinson’s disease shows promise but noted limited evidence for immersive and interactive VR activities requiring dynamic weight shifting. The Fujioka study directly addresses this gap.

Limitations and Future Directions

The study has important limitations. The sample size was very small (10 patients), the study was underpowered for efficacy conclusions, and baseline imbalance in sex and disease severity may have affected the results. The single-center design and short intervention period also limit generalizability.

Moreover, because VR training replaced only the physiotherapy component within a multimodal rehabilitation framework, the specific effect of VR cannot be isolated. Therefore, these findings should be interpreted as hypothesis-generating rather than evidence of efficacy.

The authors call for larger, adequately powered randomized trials with stratified randomization, formal sample size calculation, standardized safety assessment, and longer follow-up. Such trials are needed to determine whether the directional trends observed in this pilot study represent true therapeutic benefits of VR table tennis for Parkinson’s rehabilitation.

The Takeaway

This pilot randomized controlled trial is the first to test virtual reality table tennis for Parkinson’s disease rehabilitation. While the VR approach did not significantly improve motor symptoms compared to conventional therapy, it showed promising signals in gait performance, balance, and quality of life with no serious adverse events.

The study demonstrates feasibility and safety of VR-based table tennis rehabilitation for selected Parkinson’s patients. The consistent pattern of positive effect sizes across multiple functional outcomes justifies further investigation in larger, powered trials. For Parkinson’s patients who find conventional physiotherapy monotonous or difficult to access, VR table tennis may offer an engaging alternative that targets the specific neural pathways disrupted by the disease.
