Effect of home-based acupressure on constipation in people with spinal cord injury: a study protocol for a randomized controlled trial with a mixed-method approach

Introduction People with spinal cord injuries often experience constipation. Common surgical and conservative treatments for constipation may have long-term adverse events that outweigh their benefits in relieving symptoms temporarily. This proposed study aims to investigate the effects of acupressure on constipation, quality of life, psychosocial well-being, and bowel habits in a community-based spinal cord injury population. Methods This two-parallel-group, open-label controlled trial will randomly assign 78 eligible participants to the intervention and control groups. On the basis of receiving defecation education, the intervention group will perform a 10-day self-operated or caregiver-assisted acupressure manually, while the control group will conduct a manual light touch on the abdomen. The study will assess participants' constipation severity as the primary outcome, along with secondary outcomes including quality of life, psychosocial well-being, bowel habits, and participants’ perceptions of acupressure. Participants' perceptions of acupressure will be assessed through semi-structured focus group interviews after intervention. Other measurements will be taken at baseline, immediately post-intervention, and at a 1-month follow-up. The generalized estimating equations and content analysis will be employed to analyze the intervention effect and interview data, respectively. Discussion This study will be the first to evaluate the effect of applying acupressure in people with spinal cord injuries to improve their constipation. The intervention may offer an alternate, non-invasive therapy option for individuals with spinal cord injuries who live in the community. Trial registration This study is registered on ClinicalTrials.gov, ID: NCT05558657. Register date: September 28, 2022.
