Study arms

  • No intervention
    Control

    During the control condition cycle (no TENS), participants will refrain from using or taking other analgesics, besides ibuprofen.

  • Experimental
    One Unit TENS

    Participants will use one-unit TENS set-up where the TENS unit has 2 channels.

    Device: One Unit TENS

  • Experimental
    Two Unit TENS

    Participants will use a two-unit TENS set-up where the TENS unit has 4 channels.

    Device: Two Unit TENS

Interventions

  • DeviceOne Unit TENS

    TENS was administered by the participant at home. Application was limited to the abdominal area and instructed to be placed at the location of pain. Single unit TENS was administered via 2 channels. Participants chose an intensity of comfort and continued the treatment for 30-90 minutes per session with unlimited sessions allowed per day.

  • DeviceTwo Unit TENS

    TENS was administered by the participant at home. Application was limited to the abdominal area and instructed to be placed at the location of pain. Double unit TENS was administered via 4 channels. Participants chose an intensity of comfort and continued the treatment for 30-90 minutes per session with unlimited sessions allowed per day.

What researchers measure

Primary outcomes

  1. Analgesic effects of TENS on primary dysmenorrhea.

    To determine whether TENS will reduce pain symptoms in those with primary dysmenorrhea. Subjective pain will be assessed using an 11 point visual analog scale (VAS). The scale ranges from 0 to 10, with 0 being no pain and 10 being maximum pain.

    Time frame: 1 month

Secondary outcomes

  1. Change in analgesic pill consumption during menstruation

    Participants will be administered a daily survey where they will be asked to record analgesic pill intake throughout the day.

    Time frame: 1 month

Other outcomes

  1. The surface area of TENS pain relief

    Participants will use either one or 2 unit TENS.

    Time frame: 1 month
