Immersive virtual reality (iVR) offers an engaging rehabilitation approach, but its effectiveness versus conventional therapy remains unclear. This bi-centre observer-blinded randomised controlled trial compared iVR-and conventional upper-limb training (CON-ULT) on motor and non-motor outcomes in people with PD.  \nMethods Participants were randomised (1:1) to iVR upper-limb training (iVR-ULT) or CON-ULT for 30 min, 4 times/ week, over 4 weeks of inpatient rehabilitation. Primary outcomes were arm function (Action Research Arm Test) and hand function (Jebsen-Taylor Hand Function Test) analysed by intention-to-treat. Secondary outcomes included dexterity, finger coordination, disease severity, motivation, health-related quality of life (HRQoL), adherence, acceptability, and iVR system usability (System Usability Scale, SUS) . Outcomes were assessed pre-and postintervention by blinded therapists.  \nResults Of 97 patients screened, 58 were randomised: 29 to iVR-ULT and 29 to CON-ULT. No group-by-time interaction effects were observed in arm function. Both groups showed improved arm function (iVR-ULT: right, effect size r = 0 .402, p = 0 . 034; left, r = 0 .437, p = 0 . 021; CON-ULT: right, r = 0 . 640, p = 0 . 001; left, r = 0 . 567, p = 0 . 002; mediumto-large effects) . For hand function, significant changes were found only after CON-ULT (right: r = 0 . 656, p = 0 . 0004; left, r = 0 . 628, p = 0 . 0007), reflecting a small between-group effect (r = 0 . 275, p = 0 . 038) . For secondary outcomes, no group-by-time interaction effects were found. Across time, both groups improved in gross and fine dexterity (medium-to-large effects) . Right-hand motor speed and coordination (Finger Tapping Test) improved significantly in only the iVR-ULT group (r = 0 . 516, p = 0 . 0064), while left-hand performance improved in both groups. Disease severity improved modestly in both groups (iVR-ULT: r = 0 .431, p = 0 . 023; CON-ULT: r = 0 . 387, p = 0 . 037; medium effects), while Hoehn & Yahr stage remained stable. HRQoL analyses suggested changes in activities of daily living-related (r = 0 .494, p = 0 . 009) and cognition-related domains (r = 0 . 391, p = 0 . 039) after iVR-ULT, stigma after CON-ULT (r = 0 . 386, p = 0 . 038) and emotional well-being after both interventions (r = 0 .447, p = 0 . 018; r = 0 .406, p = 0 . 029), with low-to-medium effect  \n*Correspondence:  \nBarbara Seebacher [barbara.seebacher@i-med.ac.at](barbara.seebacher@i-med.ac.at)  \nFull list of author information is available at the end of the article  \n© The Author(s) 2025.
