Effect of a metaverse multimodal rehabilitation intervention on quality of life and fear of recurrence in patients with colorectal cancer survivors: A randomized controlled study protocol

Background Regular rehabilitation during or after cancer treatment can bring numerous benefits to colorectal cancer survivors. However, there is a lack of convenient and mobile rehabilitation support systems tailored specifically for this group. The metaverse, as a virtual reality environment, offers an innovative platform for implementing rehabilitation. Hence, our study aims to develop a metaverse-based multimodal rehabilitation program and assess its effects on enhancing outcome measures such as quality of life in colorectal cancer patients.Methods and analysis This study was designed as a randomized, single-blind controlled trial design featuring two arms: a rehabilitation group and a conventional care group. Sixty colorectal cancer survivors who have undergone curative surgery followed by adjuvant chemotherapy will be recruited for this study. The intervention will take place within the metaverse over a 4-week period. Assessments will be conducted at baseline and after 4 weeks. The intervention is grounded in the behavior change wheel framework and encompasses dietary intervention, exercise intervention, psychological support, and behavior management. Through the implementation of diverse strategies such as training, education, and motivation, our objective is to enhance patients' capacity, opportunities, and motivation, ultimately fostering healthy behaviors. Outcome measures will encompass quality of life, fear of recurrence, and lifestyle.Results The analysis includes statistical description and inference. Quantitative data will be summarized using mean +/- standard deviation for normally distributed data and medians with percentiles for non-normally distributed data. Categorical data will be presented as frequencies and percentages. Statistical tests will detect significant differences between pre- and post-intervention periods. Subgroup analysis will explore CRC stage, age, and gender in relation to outcome measures to identify factors affecting intervention efficacy.Conclusions The findings from this research will offer valuable insights and practical implications for the implementation of remote interventions and family-based interventions in the context of colorectal cancer survivorship.Trial Registration NCT05956990 (Registered 21 July 2023)
