Figure 8 Effects of IVR-based interventions on fatigue (Exclusion of 1
study).
3.2.4 | Pain analysis
Two studies17, 19 have investigated the effect of IVR
technology on pain in breast cancer patients, and the results showed
that after the intervention of IVR technology, one
study19 of VAS pain scores decreased from 7.32 to
0.33, with a significant reduction in pain compared with the
pre-intervention level, and the pain scores of the test group with IVR
combined with medication were lower than those of the control group with
medication for pain relief alone after the intervention, and the
difference was statistically significant (P < 0.05).
Another study17 found that VAS pain scores decreased
in the test group through the IVR technique intervention, and the
difference was statistically significant (P < 0.05).
3.2.5 | Quality of life analysis
Three studies14, 16, 17reported the effects of IVR
technology-based interventions on the overall quality of life of breast
cancer patients, and two studies14, 16 found that
after intervening on breast cancer patients through IVR combined with
psychological care, the quality of life scores of patients in both
groups were higher than before intervention, and the experimental group
was higher than the control group, which was a statistically significant
difference; another study17 on the other hand,
intervened on metastatic breast cancer patients through IVR technology,
and the results showed that the quality of life scores of patients in
both groups improved less, but the difference was still statistically
significant (P < 0.001).
