Feasibility and acceptability of virtual reality for cancer pain in people receiving palliative care: a randomised cross-over study.

ABSTRACT:

Context

Pain management in palliative care remains inadequate; the development of innovative therapeutic options is needed.

Objectives

To determine the feasibility and preliminary effectiveness for larger randomised controlled trials of 3D head-mounted (HMD) virtual reality (VR) for managing cancer pain (CP) in adults.

Methods

Thirteen people receiving palliative care participated in a single-session randomised cross-over trial, after which they completed a qualitative semi-structured interview. We also compared the effects of 3D HMD VR and 2D screen applications on CP intensity and levels of perceived presence. Feasibility was assessed with recruitment, completion rates and time required to recruit target sample.

Results

Although recruitment was slow, completion rate was high (93%). Participants reported that the intervention was acceptable and caused few side effects. Although participants reported significantly reduced CP intensity after 3D HMD VR (1.9 ± 1.8, P = .003) and 2D screen applications (1.5 ± 1.6, P = .007), no significant differences were found between interventions (-.38 ± 1.2, 95% CI: -1.1-.29, P = .23). Participants reported significantly higher levels of presence with the 3D HMD VR compared to 2D screen (60.7 ± SD 12.4 versus 34.3 ± SD 17.1, mean 95% CI: 16.4-40.7, P = .001). Increased presence was associated with significantly lower pain intensity (mean 95% CI: -.04--0.01, P = 0.02).

Conclusions

Our preliminary findings support growing evidence that both 3D and 2D virtual applications provide pain relief for people receiving palliative care. Given the relative lack of cybersickness and increasing access to portable VR, we suggest that larger clinical studies are warranted.
