Advantages
Virtual reality offers a number of advantages which are beneficial for people :


 * effective for hospitals to reduce their costs


 * great impact of virtual reality on pain relief


 * a lower cost of medicine and equipment
 * save organizations time and money and make work more convenient

Disadvantages
There are different types of issues based on virtual reality :


 * VR devices were not comfortable


 * not useful for patients with some special symptoms

Chronic pain
Virtual reality (VR) has been shown to be effective in decreasing pain for procedural or acute pain but to date there have been few studies on its use in chronic pain. Chronic pain patients can tolerate the VR session without the side effects that sometimes come with VR such as headaches, dizziness or nausea.

Rehab
Virtual reality is also helping patients overcome balance and mobility problems resulting from stroke or head injury. In the study of VR, the modest advantage of VR over conventional training supports further investigation of the effect of video-capture VR or VR combined with conventional therapy in larger-scale randomized, more intense controlled studies. It shows the VR-assisted patients had better mobility when the doctors checked in two months later. Other research has shown similarly successful outcomes for patients with cerebral palsy undergoing rehab for balance problems.

Memory loss
VR smoothly blurs the demarcation between the physical world and the computer simulation as surgeons can use latest versions of virtual reality glasses to interact in a three-dimensional space with the organ that requires surgical treatment, view it from any desired angle and able to switch between 3D view and the real CT images.

Efficacy
VR combined real instrument training was effective at promoting recovery of patients' upper-extremity and cognitive function, and thus may be an innovative translational neurorehabilitation strategy. In the study of smoke people, the experimental group showed greater therapeutic effects in a time-dependent manner than the control group, especially on the motor power of wrist extension, spasticity of elbow flexion and wrist extension, and Box and Block Tests. Patients in the experimental group, but not the control group, also showed significant improvements on the lateral, palmar, and tip pinch power, Box and Block, and 9-HPTs from before to immediately after training.
