Traditional rehabilitation, although effective, sometimes faces challenges such as the uniformity of exercises and the reduction of patients' motivation. By creating attractive and interactive environments, virtual reality reduces these challenges and provides a new experience in treatment. In traditional rehabilitation methods, patients usually perform repetitive and monotonous exercises, which can lead to a decrease in their motivation and participation in the treatment process. This is especially true in long-term rehabilitation, such as rehabilitation after a stroke or spinal cord injury. By providing interactive and simulated environments, virtual reality reduces these challenges and provides a new experience in treatment. Using VR headsets and specialized software, patients can practice in various virtual environments such as parks, kitchens, or urban paths. These environments are designed to provide physical and cognitive exercises in a playful and engaging manner, leading to increased patient motivation and engagement. Studies have shown that the use of virtual reality in rehabilitation can help improve motor function, balance and coordination of patients. For example, in one study, patients showed significant improvement in their walking speed and balance after using VR-based rehabilitation programs. In addition, virtual reality in rehabilitation provides the possibility of providing immediate and accurate feedback to patients. Using advanced sensors and algorithms, VR systems can accurately monitor patients' movements and provide the necessary feedback to correct movements and improve performance. This feature also helps physiotherapists adjust treatment plans based on real-time data. Another advantage of virtual reality in rehabilitation is the possibility of simulating daily activities in safe and controlled environments. Patients can practice tasks such as cooking, driving or crossing the street in virtual environments, which helps them prepare to return to independent living. Despite the many benefits, the use of virtual reality in rehabilitation also comes with challenges. Among these challenges are high initial costs, the need to train patients and physiotherapists, and the possibility of motion sickness (cybersickness). However, as technology advances and costs decrease, these challenges are expected to decrease in the future. In general, virtual reality has been able to create a transformation in the field of rehabilitation by providing new and interactive methods. Despite the existing challenges, the benefits of this technology in improving the quality of treatment and increasing access to rehabilitation services are significant. With further development and cost reduction, virtual reality is expected to become an integral part of rehabilitation processes. Advantages of virtual reality in rehabilitation **1. Increasing the motivation and participation of patients One of the main challenges in traditional rehabilitation is the uniformity of exercises and the reduction of patients' motivation. By creating interactive and simulated environments, virtual reality solves this problem and provides a new experience in treatment. Using gaming elements, virtual reality environments make exercises more attractive and increase patients' motivation to continue treatment. Studies have shown that this method can lead to improved treatment results. For example, in a study published in the Journal of NeuroEngineering and Rehabilitatio, stroke patients who used VR-based rehabilitation programs showed significant improvement in their motor performance and balance. In addition, virtual reality in rehabilitation provides the possibility of providing immediate and accurate feedback to patients. Using advanced sensors and algorithms, VR systems can accurately monitor patients' movements and provide the necessary feedback to correct movements and improve performance. This feature also helps physical therapy clinics adjust treatment plans based on real-time data. For example, in a study published in the journal Sensors, the use of virtual reality in the rehabilitation of stroke patients has led to an improvement in their cognitive and physical performance. **2. Instant and accurate feedback One of the prominent features of virtual reality in rehabilitation is providing immediate and accurate feedback to patients. In traditional methods, patients may not be sure of the correctness of their exercises until the next meeting with the physiotherapist. But by using VR, patients can be aware of the correctness of their movements at the same moment. Using motion sensors and advanced algorithms, virtual reality systems accurately monitor patients' movements and provide the necessary feedback to correct movements and improve performance. These instant feedbacks help patients to perform their exercises correctly and avoid possible injuries. Also, physical therapists can use the collected data to adjust treatment plans based on the specific needs of each patient. For example, in a study published in the Digital Health Mavens magazine, the use of virtual reality in the rehabilitation of patients has led to improved motor performance and increased motivation. **3. Safe and controlled environments Rehabilitation in real-world settings may be associated with risks such as falls or other injuries, especially for patients suffering from serious injuries. Virtual reality solves this problem by creating simulated and risk-free environments. Patients can do their exercises in virtual environments without worrying about possible risks. This is especially helpful for people suffering from serious injuries. In addition, virtual reality allows the simulation of everyday activities in safe and controlled environments. Patients can practice tasks such as cooking, driving or crossing the street in virtual environments, which helps them prepare to return to independent living. For example, in a study published in Sensors magazine, the use of virtual reality in the rehabilitation of patients has led to improved motor performance and increased motivation. **4. Improve cognitive and physical performance Virtual reality is not only effective in improving the physical performance of patients, but it can also help improve their cognitive performance. This is especially important in cases such as stroke or brain injuries. In addition, virtual reality in rehabilitation can help improve the physical performance of patients. By using interactive and simulated environments, patients can perform their physical exercises in an attractive and effective way. This leads to increasing the motivation and participation of patients in the treatment process. **5. Greater access to rehabilitation services One of the important advantages of virtual reality in rehabilitation is increasing patients' access to medical services. Patients living in remote areas or with limited mobility may have limited access to rehabilitation clinics. Virtual reality solves this problem by providing telehealth services. Using virtual reality equipment, patients can do their exercises at home and communicate with physiotherapists remotely. This helps to increase justice in the provision of medical services and enables more patients to access rehabilitation services. In addition, virtual reality in rehabilitation can help reduce costs associated with commuting and waiting time. Patients can benefit from rehabilitation services without the need to be physically present at the clinic, which saves time and money. Challenges of using virtual reality in rehabilitation **1. High initial costs One of the main obstacles in the widespread adoption of virtual reality in rehabilitation is its high initial costs. VR equipment, including headsets, sensors, and specialized software, can be expensive for many clinics and patients. For example, costs associated with developing and testing new VR software can include hiring software developers and clinical experts, as well as the costs of running clinical trials. In addition, the costs related to technical support and training of health workers to use this technology should also be considered. The time required to train employees may vary depending on the complexity of the hardware and software used. In a Canadian economic study, the costs associated with implementing a VR-based home rehabilitation program for stroke survivors were estimated to be between CAD 475 and CAD 482 per patient. These costs may be a serious obstacle to the use of virtual reality in rehabilitation for small medical centers or patients with limited financial resources. Although in the long run, the use of VR can lead to reduced costs associated with commuting and waiting time, high initial costs can limit the adoption of this technology. **2. The need for training and familiarity with technology The effective use of virtual reality in rehabilitation requires the familiarization of patients and medical staff with this technology. Some patients, especially the elderly, may not be familiar with new technologies and may require initial training. Also, medical staff should receive the necessary training to use VR equipment and interpret the obtained data. Lack of familiarity with the technology can lead to resistance to VR adoption. Some patients may feel discomfort or anxiety when facing virtual environments. To overcome this challenge, providing simple and understandable training, and providing appropriate technical support can be effective. Also, designing simple and user-friendly user interfaces can help increase the adoption of VR among patients and medical staff. Ensuring that users can easily interact with VR systems is critical to the success of implementing VR-based rehabilitation programs. **3. Technical problems and support The use of virtual reality equipment requires appropriate technical support to avoid problems during treatment. VR systems may experience issues such as hardware incompatibilities, software bugs, and connectivity issues. These issues can affect the user experience and reduce the effectiveness of the treatment. Experienced and trained technical support teams are needed to ensure proper functioning of VR systems. Also, regular software updates and hardware maintenance are necessary to avoid technical problems. In addition, there is a need for proper infrastructure, such as high-speed Internet and powerful computer equipment, to run VR applications. In areas where these infrastructures are not available, the use of virtual reality in rehabilitation may face more challenges. **4. The possibility of motion sickness One of the challenges of using virtual reality in rehabilitation is the possibility of motion sickness or "cybersickness". Some people may experience symptoms such as dizziness, nausea, headache and fatigue while using VR. These symptoms are usually caused by a mismatch between visual information and the body's sense of balance. To reduce these symptoms, techniques such as reducing the field of view, using fixed reference frames and optimizing the frame rate can be used. Also, using methods such as "teleportation" instead of continuous movement in virtual environments can help reduce the symptoms of motion sickness. It is important that VR-based rehabilitation programs are designed to minimize the risk of motion sickness. This includes designing virtual environments taking into account the physical limitations of patients and providing the necessary training for the proper use of VR equipment. In conclusion, virtual reality in rehabilitation as an innovative tool has been able to create a significant transformation in treatment methods. By providing interactive and attractive environments, this technology increases the motivation of patients and enables more effective exercises. Studies have shown that the use of VR can help improve motor function, reduce pain and increase the quality of life of patients. However, challenges such as high initial costs, the need for user training, technical difficulties, and the possibility of motion sickness are obstacles to the widespread adoption of this technology. To overcome these obstacles, it is necessary to develop cost-effective solutions, provide appropriate training and improve the design of systems. ❓ Frequently asked questions about virtual reality in rehabilitation
