Virtual Reality (VR) rehabilitation in occupational therapy (OT) is an innovative approach that utilizes
virtual reality technology to aid in the rehabilitation process for individuals with various physical,
cognitive, or emotional impairments. VR rehabilitation has gained popularity in recent years due to its
potential to enhance engagement, motivation, and functional outcomes for patients.
Key benefits of using VR in OT rehabilitation include:
1. Immersive and engaging therapy: VR provides a more immersive and interactive experience
compared to traditional therapy methods, making it more enjoyable and motivating for patients. This
can lead to increased participation and compliance with therapy sessions.

3. 2. Personalized and adaptive interventions: VR systems can be tailored to meet the specific needs and
abilities of individual patients. Therapists can adjust difficulty levels and activities based on the patient's
progress, ensuring that the therapy remains challenging yet achievable.
3. Real-life simulations: VR environments can replicate real-life situations, enabling patients to practice
and develop skills necessary for daily living activities and vocational tasks. For example, a patient
recovering from a stroke can practice activities like cooking, dressing, or using public transportation in
a simulated environment.
4. Enhanced motor skills training: VR rehabilitation can be particularly effective in improving motor
skills. Patients can work on balance, coordination, and strength while engaging in virtual activities and
