Effect of Transcutaneous Electrical Nerve Stimulation or Acupressure on Pain in Patients With Head and Neck Cancer

Participants received TENS therapy at two specific acupoints - Hegu (LI4) and Lieque (LU7). Surface electrodes were placed over the acupoints, and stimulation was delivered using a standard TENS device.

The acupressure group placed the acupoint patches on the Hegu and Lieque points on both hands and pressed each acupoint with the index finger and thumb for 1 minute, 3 times a day, each time for about 4 minutes.
