About

The aim of the study was to evaluate the analgesic effect of transcutaneous electrical nerve stimulation High (100 Hz) and low (4 Hz) frequency in postpartum pain after cesarean section.

Full description

Mothers were randomly divided into three groups (G100, G4 and placebo (GP) - appliance off) and evaluated by NRS (numeric rating scale) before, immediately after application of TENS, and every 20 minutes until he was one hour after the application of electroanalgesia, to verify its effectiveness over time.
