VR Stroke Recovery: Regain Movement
- Virtual reality (VR), when combined with standard treatment, can improve arm function in stroke patients, according to a new review published in the Cochrane Database of systematic Reviews.
- The Cochrane review, which was initially released in 2011, now includes data from 190 trials involving 7,188 participants.
- "More time in therapy improves outcomes after stroke," said Professor Kate Laver of Flinders University, the lead author.
Virtual Reality Could Help Stroke Survivors Regain Movement
Virtual reality (VR), when combined with standard treatment, can improve arm function in stroke patients, according to a new review published in the Cochrane Database of systematic Reviews. The findings suggest that virtual reality therapy may be a valuable tool for enhancing rehabilitation,particularly by extending the duration of therapy.
The Cochrane review, which was initially released in 2011, now includes data from 190 trials involving 7,188 participants. Researchers from Australia, Canada, and the United States compared virtual reality stroke rehabilitation to conventional therapy. They found that VR may lead to slight improvements in arm function and activity. More significant gains were observed when VR was used to supplement usual care, increasing overall therapy time.
“More time in therapy improves outcomes after stroke,” said Professor Kate Laver of Flinders University, the lead author. She added that virtual reality offers an engaging and relatively inexpensive method to increase therapy time without direct clinician supervision.
The review also indicated that VR may improve balance and reduce activity limitations. though, the impact on mobility, participation, and quality of life remains uncertain due to limited evidence.
Many trials were small and utilized basic VR technologies, such as off-the-shelf gaming systems. Few studies have assessed immersive, head-mounted systems, leaving their effectiveness unclear. Most current VR programs focus on movement training rather than functional abilities like dressing or cooking.
Professor laver noted the potential of VR to simulate real-life environments,allowing clinicians to safely practise tasks that would be unsafe in the real world. She urged researchers to develop more sophisticated, function-focused therapies.
Adverse events were rare and mild,suggesting that VR is generally safe and well-tolerated.
The review emphasizes the need for larger, well-designed studies, particularly those evaluating immersive and task-specific VR technologies, to optimize the use of VR in stroke recovery.
