This review examined the efficacy of virtual reality for training, in comparison to an alternative intervention or no intervention, on upper limb function and activity. The publication is an update of the writers' review first printed in 2011 and then revised in 2015. With this iteration, 11 trial and databases registries were searched, such as randomized and quasi-randomized trials of virtual reality for training in adults after stroke. A total of 72 trials (with 2470 participants) were included in the review.
While many recoveries after stroke are regarded as made from the first couple of weeks, patients may make improvements in functional jobs many months after a stroke. Prior research has indicated that repetitive task training is effective in certain aspects of rehabilitation, like improving walking distance and speed and improving upper limb function. Virtual reality for training is a fairly recent procedure which can enable mimicked practice of functional tasks at a higher dosage than conventional treatments. Virtual reality for training has been described as the"use of interactive simulations made with computer hardware and software to provide users with opportunities to engage in surroundings that appear and feel similar to real-world objects and events"
In assessing the main outcome for this review paper, virtual reality for training has been compared with the identical dose of traditional therapy, and the outcomes were not statistically important for upper limb function. But when the virtual reality for training was used to supplement standard care (providing participants in the intervention group using a greater dose of treatment ), there was a statistically significant difference between groups. There was a trend suggesting that personalized virtual reality for training applications were preferable to commercial game goods; however, these findings were not statistically significant.
Proof of neuroplasticity as a result of training in virtual reality for training is small; nonetheless, neuroimaging findings are directing the development of virtual reality for training. The writers are keen to note that one big advantage of virtual reality for training applications, that has been underutilized to date, is they allow clinicians in order to trial jobs that are dangerous to practice in the real world, such as crossing the road. In addition, some programs are designed to be used without oversight, meaning increased dosage of treatment can be supplied without improved staffing levels. It is necessary to continually evaluate the effectiveness of virtual reality for training so as to direct future design and usage.
