Data were collected using a pain assessment questionnaire and analyzed with the Wilcoxon Signed Rank Test. Results: Before the intervention, 10 participants (24.4%) reported mild pain, 12 participants (29.3%) reported moderate pain, and 19 participants (46.3%) reported severe pain. After the intervention, 9 participants (22.0%) experienced mild pain, and 32 participants (78.0%) reported moderate pain, while no participants reported severe pain. Statistical analysis revealed a Z-score of -5.282 with a p-value of 0.000 (p < 0.05). Conclusion: Prenatal exercise effectively reduces back pain in third-trimester pregnant women. Midwives are encouraged to provide comprehensive education and training on appropriate prenatal exercise techniques to empower pregnant women to manage pain independently at home.]]>
