Clinical bottom line
AI-driven virtual reality (VR) interventions show promising potential to enhance upper limb motor recovery in people with multiple sclerosis (MS). Emerging evidence supports VR’s feasibility, acceptability, and preliminary efficacy in improving motor function and engagement compared to conventional therapy. However, current data are mainly from small feasibility studies and systematic reviews highlighting heterogeneity in protocols and outcomes. Larger, well-controlled trials are needed to establish standardized VR rehabilitation protocols and confirm long-term benefits in MS populations (Webster et al., 2021; Kalron et al., 2019).
What the evidence shows
Webster et al. (2021) conducted a systematic review of upper limb rehabilitation using VR in MS, concluding that VR-based interventions are generally well tolerated and may improve motor outcomes, including dexterity and strength. The review noted variability in intervention duration, VR systems used, and outcome measures, limiting definitive conclusions but underscoring VR’s therapeutic promise.
Kalron et al. (2019) reported on a feasibility study of VR training targeting upper limb motor function in MS patients, demonstrating improvements in motor performance and high patient engagement. Their protocol emphasized task-specific, repetitive movements facilitated by immersive VR environments, suggesting enhanced neuroplasticity potential.
Webster et al. (2023) explored clinician and patient perspectives on VR for upper limb impairment in MS, revealing optimism about VR’s role in rehabilitation but highlighting barriers such as accessibility, cost, and need for tailored programs.
Huang et al. (2025) introduced AI-driven focus-enhancing augmented feedback within VR rehabilitation, aiming to maintain patient engagement and optimize motor learning, representing an innovative direction to personalize therapy intensity and content.
Additional case medical research studies (2019) support the feasibility of telerehabilitation VR platforms, expanding access for MS patients with mobility limitations.
Caveats and uncertainty
Most studies to date are small-scale feasibility or pilot trials with limited sample sizes and short follow-up periods.
Heterogeneity in VR hardware, software, and training protocols complicates cross-study comparisons.
Long-term retention of motor gains and functional impact on daily activities remain underexplored.
AI integration in VR rehabilitation is nascent, with limited clinical validation.
Cost-effectiveness and implementation logistics in routine clinical practice require further evaluation.
Patient selection criteria and optimal dosing parameters for VR interventions are not yet standardized.
How this may change practice
Clinicians may consider incorporating VR-based upper limb rehabilitation as an adjunct to conventional therapy for motivated MS patients, especially those with mild to moderate impairment.
AI-enhanced VR platforms could enable personalized, adaptive training programs that maintain engagement and maximize motor recovery.
Telerehabilitation VR options may improve access for patients with mobility or geographic barriers.
Multidisciplinary collaboration including rehabilitation specialists, neurologists, and technology developers will be essential to optimize VR integration.
Ongoing research and clinical trials will inform evidence-based guidelines and reimbursement policies supporting VR adoption.
