  • Accessible healthcare: AR and VR devices can bring healthcare to underserved areas, providing patients with access to specialized care they may not otherwise have.

Applications of VR & AR in medical devices

Augmented reality and virtual reality have found a multitude of applications in treating patients across various domains.

Medical education and training

VR and AR effectively facilitate theoretical learning for medical students and healthcare professionals. Such learning environments may be applied to anatomy instruction, medical procedure simulation, medical device training, and interprofessional education. It helps them acquire hands-on skills in risk-free conditions by simulating difficult, dangerous, or expensive scenarios and enables planning for future operations. This way, the use of training dummies and cadavers is minimized.

Surgery

AR surgical navigation systems help guide surgeons during surgery. Using cutting-edge tools like 3D imaging, computer-assisted planning, and real-time monitoring, surgical navigation systems have improved results by enabling surgeons to precisely find and visualize a patient’s anatomy during surgical procedures. AR surgical navigation systems have been particularly beneficial in neurosurgery, orthopaedic and spine surgery, and laparoscopic surgery due to improved accuracy, reduced risk of complications, and shortened operating times.

Pain management

VR helps lower the level of pain or extreme discomfort by diverting a patient’s attention to a soothing virtual environment and minimizing the use of potentially harmful painkillers. It is also effective as an alternative method of pain relief and can also be used during childbirth as a substitute for epidural anaesthesia and other drugs.

Rehabilitation

Various illnesses can lead to severe damage to the brain, limbs, and nerves that can deteriorate motor skills. Patients can regain these skills using virtual reality. VR transforms therapy sessions into a gamified experience, encouraging them to achieve virtual goals. Patients can relearn how to carry out their daily tasks in the virtual environment, aiding their recovery.

AR-based rehabilitation can simulate real-world activities and adjust the difficulty level of tasks based on the patient’s progress, making it personalized and adaptive. AR-based rehabilitation can stimulate reflexes and problem-solving skills. Additionally, patients can practice balance and coordination drills in a secure and monitored setting, reducing the risk of injuries.

Helping patients with neurodegenerative disorders

With AR technology, people with neurodegenerative disorders like Alzheimer’s and Parkinson’s disease can improve their quality of life through cognitive stimulation and social interaction. AR technology-created virtual social settings help enhance attention and analytical skills.

Scientists have already proven the positive effects of VR for diagnosing Alzheimer’s disease and relieving its symptoms. For example, Cambridge University researchers designed and implemented a navigation test that uses virtual reality to detect patients with early Alzheimer’s and is more reliable than a conventional cognitive assessment.

Overcoming mental health disorders and complexes

Virtual reality can be effectively applied in psychotherapy to treat various phobias and mental health conditions. Technology allows doctors to create a controllable environment and put patients in conditions preset individually for each case to train them to overcome their fears and gain confidence.

Post-traumatic stress disorder is another condition that can be effectively treated using virtual reality devices. The immersive experience provided by VR can also be used as a relaxation therapy to deal with various anxieties and stress-related disorders.

Diagnosis and telehealth

AR medical devices can monitor patient data in real time and provide remote access to medical information. They help healthcare providers gather vital information about a patient’s condition, such as reports and statistics, and visualize symptoms through full-body scans. AR technology is also used for thermal imaging, which was especially useful during the COVID-19 pandemic to assess a patient’s temperature without physical contact.

This technology is also used for telehealth and reduces costs associated with physical visits. In telehealth visits, AR devices can enhance the patient experience and enable doctors to consult with patients remotely.

AR and VR have tremendous potential to transform the medical device industry, there are still challenges to overcome, such as cost, integration with existing systems, and ensuring patient data privacy and security. However, as technology advances, we can expect to see more innovative applications of AR and VR in healthcare, leading to improved patient outcomes and better medical device solutions.
