Cesarean section (C-section) rates in Indonesia exhibit a wide range, often surpassing recommended thresholds, particularly in private healthcare facilities. Effective management of postoperative pain, including strategies like early mobilization, is crucial in enhancing wound healing outcomes. This study aimed to evaluate the impact of early mobilization on pain levels among postoperative cesarean section clients. The research employed a descriptive correlational design using a One Group Pretest-Posttest approach conducted at Royal Prima Marelan Hospital in January 2024. The study population consisted of laboring mothers planning to deliver at the hospital, averaging around 52 attendees per month over the last three months. Utilizing the Slovin formula, a sample size of 35 was determined and selected through consecutive sampling based on inclusion criteria. Bivariate statistics were employed to analyze the relationship between variables, with hypothesis testing indicating the validity of hypotheses based on a significance level of 0.05 (p ≤ 0.05 for “meaningful” results and p > 0.05 for “not meaningful” results). The study used a paired t-test for bivariate analysis to assess pain scale changes pre- and post-early mobilization. The findings from the Wilcoxon Test revealed a significant difference, with Early Mobilization demonstrating a positive effect on reducing Pain Levels among inpatients at Royal Prima Marelan Hospital in 2024. Evaluation of Pain Levels in post-cesarean section clients indicated that before Early Mobilization, a majority experienced heightened pain levels, including a small proportion with severe pain. However, after Early Mobilization, while most clients reported a slight increase in pain levels, a minority experienced a more substantial increase. These outcomes suggest that Early Mobilization influences changes in pain levels among postoperative clients at Royal Prima Marelan Hospital in 2024.
