Although caesarean sections (CSs) are essential for the management of obstructed labour and other obstetric complications, postoperative pain, delayed recovery and complication risks continue to be significant challenges in perioperative management. Improvements in traditional medications and surgical techniques have helped, yet issues, including medication side effects and extended recovery times, persist. Therefore, it is particularly important to seek non-pharmacological interventions, such as acupoint stimulation, to optimise the perioperative management of CS. The aim of this systematic review protocol is to synthesise the available evidence and assess the effect of acupoint stimulation in the perioperative period of CS.

We plan to search PubMed, Web of Science, EMBASE, Scopus, the Cochrane Library and China National Knowledge Infrastructure, from their inception to August 2025. Primary outcome indicators will include pain, time to first defecation, time to first bowel movement and time to return of bowel sounds. Secondary outcome indicators will include postoperative complications, such as nausea and vomiting, bloating, anxiety and depression, as well as length of hospital stay and morphine consumption. Subgroup analyses, meta-regression and sensitivity analyses will be used to investigate the potential sources of heterogeneity and to test the stability of the results. Trial sequential analysis will be introduced to enhance the reliability of the evidence.

No ethical approval is required as this study synthesises the existing published data. Results will be disseminated through peer-reviewed publications and conference presentations. Any protocol amendments will be documented in PROSPERO and detailed in the final publication.

Falls are common causes of disability, reduced disability-adjusted life years and death in older adults. Balance deficits and cognitive impairment are common causes of falls. Dual-task training is a new strategy that can potentially improve balance and cognitive function, leading to decreased falls. The effectiveness and cost-effectiveness of self-administered dual-task (sDT) training to improve balance and prevent falls is not known. We developed sDT training combining physical and cognitive tasks to improve balance and reduce falls. The proposed randomised controlled trial (RCT) with economic evaluation is to test the effectiveness and cost-effectiveness of the sDT compared with self-administered single-task training (sST) in this population.

In this RCT, we will recruit 190 community-dwelling older adults with a history of at least one fall over the last 6 months from 11 elderly centres. The older adults will be randomly assigned to the sDT (n=95) and sST groups (n=95). Each group will be offered in six training workshops to teach the participants either sDT or sST depending on the group allocation. Each workshop will last an hour and will be held once every 2 weeks for 3 months. Besides, the participants will be instructed to repeat the exercises at home two times weekly for 3 months. Following the intervention phase, the participants will continue unsupervised home-based exercises for 6 months. Assessments will be performed before, after and 6 months after completing the intervention. A fall calendar and cost diary will be provided to each older adult to record the number of falls and fall-related costs during and after the intervention to assess fall incidence and cost-effectiveness. Effectiveness will be assessed using a negative binomial regression model following the intention-to-treat principle for falls and a linear mixed model for the additional measure and cost-effectiveness using a Markov model.

This study has ethical approval from the PolyU Institutional Review Board for conducting research on human subjects (Ref: HSEARS20210322005). The results will be disseminated through seminars for individuals and health practitioners, international conferences and published in peer-reviewed journals.
