BACKGROUND: Stroke is a leading cause of long-term disability worldwide; therefore, an effective rehabilitation strategy is fundamental. Mirror therapy (MT) has been a popular approach for upper extremity rehabilitation, but it presents some limitations. Recent advancements in virtual reality (VR) technology have introduced immersive VR-based MT, potentially overcoming these limitations and enhancing rehabilitation outcomes. AIM: This study aimed to evaluate the effectiveness of a novel 360 degree immersive virtual reality-based MT (360MT) in upper extremity rehabilitation for stroke patients, comparing it to traditional MT (TMT) and conventional physical therapy control group (CG). DESIGN: A prospective, active control, assessor blinded, parallel groups, randomized controlled trial. POPULATION: Forty-five participants with chronic stroke within six months of onset. METHODS: The participants were randomly allocated to 360MT, TMT, or CG groups. Outcome measures included Fugl-Meyer Assessment for Upper Extremity (FMA-UE), Box and Block Test (BBT), and Manual Function Test (MFT). Additionally, patient experience and satisfaction in the groups of 360MT and TMT were assessed through questionnaires and interviews. RESULTS: Results revealed that the 360MT group showed significantly greater improvements in FMA-UE, MFT and BBT compared to TMT (p < 0.05) and CG (p < 0.001) groups. Patient experience and satisfaction were more favorable in the 360MT group, with participants reporting higher engagement and motivation. CONCLUSIONS: 360MT appears to be a promising approach for upper extremity rehabilitation in stroke patients, providing better outcomes and higher patient satisfaction. However, further research is needed to confirm these findings and strengthen the evidence base for 360MT in stroke rehabilitation.
