A cesarean section (SC) is a surgical procedure used to deliver a baby through an incision in the abdominal wall and uterus, especially when normal labor is risky for both mother and baby. Although SC can be life-saving, this procedure can cause postoperative pain that can slow recovery. This study aims to evaluate the effect of early mobilization on pain reduction in post-SC patients at Royal Prima Hospital Medan. This study uses a correlational descriptive design with the One Group Pretest-Posttest approach. The research sample consisted of 43 respondents, which were taken using the consecutive sampling method. The independent variable is early mobilization, while the dependent variable is the level of pain measured using a facial scale. The results showed that most patients experienced pain at a fairly high level before early mobilization. After early mobilization, there was a significant decrease in pain levels, with the average pain score dropping from 3.67 (before early mobilization) to 2.15 (after early mobilization). The paired t-test statistical test showed a value of p = 0.003, which showed that the decrease in postoperative SC pain had a statistically significant difference. These findings indicate that early mobilization may effectively reduce post-SC pain and accelerate patient recovery. Therefore, early mobilization should be part of standard care for post-SC patients to improve comfort and speed up recovery.
