Summary

This randomized clinical trial aims to evaluate the effectiveness of low-level laser therapy compared with sham treatment on pain intensity and perineal wound healing quality in the immediate postpartum period. The study seeks to determine whether low-level laser therapy can reduce perineal pain and improve healing outcomes in women with perineal trauma after vaginal birth.

Conditions

• Pain
• Perineal Healing

Interventions

Type	Name	Description
DEVICE	low-level laser therapy	Low-level laser therapy will be applied to the perineal region of postpartum women with perineal trauma after vaginal birth. The intervention will be performed using a low-level laser device applied directly to the perineal wound area in the immediate postpartum period. The laser will be administered according to predefined parameters (wavelength, energy density, and application time) to promote analgesia and enhance tissue repair.
DEVICE	Sham treatment	Participants allocated to the control group will receive a sham treatment using the same device and procedure; however, the laser emission will be inactive.
