Summary

This study tested a light and laser device (photo-biomodulation) on the wound of 180 women after planned C-sections. The goal was to see if using the device twice a day could reduce pain and the need for strong painkillers. Researchers measured pain during movement and after six weeks to see if the treatment helped.
