Study summary

A single-centre, randomised controlled, double blind study comparing use of the Allay pulsed shortwave therapy treatment versus a placebo device or no treatment for management of primary dysmenorrhea.

Read the detailed description

Women participating in the trial will be randomly allocated to any of the three arms of the study.

  • Treatment for 2 menstrual cycles using the PSWT Allay device (BioElectronics Corp, Frederick USA)
  • Treatment for 2 menstrual cycles using a placebo device
  • No treatment. If they are allocated to a device both the participant and the clinician will be blinded at to weather they are using the active device or the placebo.

Primary Outcome measures are:

  • A reduction in dysmenorrhea as measured by the highest pain score on a 10cm visual analogue scale.
  • A reduction in average pain score on a 10cm visual analogue scale
  • A reduction in use of analgesia as recorded in a pain diary
  • Improvement in quality of life as measured through a validated quality of life assessment tool (SF-36 questionnaire)

    • Improvement in menstrual symptoms as recorded through a validated questionnaire (the Modified Menorrhagia Multi-attribute Scale (MMAS)).
  • Device acceptability as measured on a 5-point Likert scale ranging from "unacceptable" to "totally acceptable".
  • Impact upon associated cyclical symptoms as recorded in a patient symptom diary

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Female with persistent (>3months) cyclical period pain associated with menstruation (defined as 5 or more on VAS).
  • Able to give written,
  • Able to wear device and keep up-to-date records of use
  • Agrees to attend follow up
  • If currently using hormonal agrees to continue on the same dose for the duration of the trial.

Exclusion criteria

Exclusion Criteria:

  • Age under 16 years.
  • Trying to conceive or \<6 weeks post partum
  • Currently participating or planning to participate in another clinical trial
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

    Device: Placebo

  • No intervention
    No treatment

    No intervention is given and a menstrual diary is completed for 2 cycles.

Interventions

  • DeviceAllay

    pulsed shortwave therapy treatment for painful periods

  • DevicePlacebo

    A placebo device is given which is identical to the Allay device but emits no pulsed shortwave therapy.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Nov 2017 (actual). Primary completion is estimated for Oct 2018, 10 months after the start.

Of 178 non-industry interventional studies with no phase under Dysmenorrhea, half reached primary completion within 8 months of starting (the median), counting those still running; a quarter within 4 and three quarters within 16. This study's planned 10 months is above that.

Counting every sponsor, half of 188 studies reached it within 8 months; a quarter within 3 and three quarters within 16.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 13, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
