Using visual feedback manipulation in virtual reality to influence pain‐free range of motion in people with nonspecific neck pain
Pain Practice Apr 14, 2021
Kragting M, Schuiling SF, Voogt L, et al. - Researchers examined (1) if an increase and decrease in the pain‐free range of motion (ROM) occurred when visual feedback understated or overstated true rotation in people with neck pain and (2) whether this impact was more pronounced when pain was chronic. A VR‐headset was worn by people with subacute and chronic nonspecific neck pain and then they rotated their head to the left and right until the onset of pain. Visual feedback concerning the aggregate of movement was either equal, 20% less, or 20% greater than their actual rotation. The VR‐headset sensors were used to determine maximal pain‐free ROM. Mixed‐design ANOVA was used to analyze data. Findings did not confirm that the pain‐free ROM can be altered in people with neck pain by manipulating visual feedback regarding the amount of rotation in a VR environment. In addition, there appeared no impact of the duration of neck pain on the effect of visual feedback manipulation on the pain‐free range of motion.
