SUMMARY OF FINDINGS
Virtual reality (VR) interventions vs usual care or no intervention for back pain
|Outcome||Number of Studies||Effect||Quality of Evidence|
|Pain intensity immediately after the intervention||16*||People who had a VR intervention had an average reduction of 0.67 points on a pain scale** compared to usual or no intervention||Low|
*studies in the review that compared VR with another intervention and reported results using a pain scale
** pain scale ranging from 1 to 10: 1 = minimal pain and 10 = worst pain ever. In many trials of pain treatment, the minimal difference considered to be important (patients would notice) is 1 full point.
This was a systematic review of 24 randomized controlled trials published up to September 2020.
Who? This review included 900 adults with back pain (average age 20 to 70). People who had neck pain or spinal cord injuries were excluded.
What? The reviewers included studies that compared interventions using virtual reality with usual care or no intervention for back pain.
Usual care or no intervention
Electronic equipment (e.g. computer tablet or special head-mounted display) used to make a person feel like they are in an artificial environment where they performed physical activities like exercises, horse-back riding, yoga
Many of the studies used virtual reality to turn exercises into a game
Usual care, which most often involved physical therapy in the real-world
Virtual reality can make a person feel like they are in an artificial environment. Input devices such as joysticks, handheld controllers or tracking gloves tell a computer what actions the person is performing within the virtual environment. Output devices like headphones, pressure pads, and a head-mounted video display show the person the effect of their actions. Virtual reality may reduce pain by distracting the brain from pain signals, reducing fear of movement (because you have a different "body" in virtual reality), and increasing motivation to perform physical activities. The reviewers in this paper wanted to know if interventions using virtual reality equipment would improve back pain. They found that there was a small reduction in pain. However, the quality of the evidence was low because the treatments were so different, it was difficult to compare them. Further research is needed before VR interventions can be recommended for treating back pain.
