Treatment of Dysmenorrhoea With the OVA TENS Apparatus

January 12, 2007 updated by: The Hospital of Vestfold

Dysmenorrhoea (menstrual pain) is a common complaint among women, leading to use of analgesics, reduced quality of life, and interference with daily activities such as going to work or school.

Transcutaneous electrical nerve stimulation (TENS) is a well established method for treatment of pain. Several clinical studies have shown TENS treatment to be effective against dysmenorrhoea. A TENS apparatus specifically developed for the treatment of dysmenorrhoea has now become commercially available (OVA), but is has not been tested in clinical studies.

This study will be done to evaluate the clinical utility of treatment with OVA in women with primary dysmenorrhoea.

Detailed Description

Study aims: To compare perception of dysmenorrhoea with and without use of OVA.

Design: Prospective, clinical study lasting four months. The women will use the OVA apparatus during every other menstruation.

Inclusion: 20 female volunteers with primary dysmenorrhoea.

Exclusion: Pregnancy, either ongoing or planned during the study period. Secondary dysmenorrhoea.

Consent: The participants will receive verbal and written information and will sign a consent form.

Randomisation: The participants are randomised to start with either active treatment or observation by drawing a closed, opaque envelope containing the forms for registration of perception of pain.

Registering pain: The participants will mark their perceived degree of dysmenorrhoea daily on 10 cm visual analogue scale (VAS) during each menstruation.

Filling in forms: During each of the four menstruations throughout the study period the participants will respond daily to the questions on the form and note degree of pain on the VAS. At the end of each menstruation they will mail the current form in a stamped and addressed envelope to the study coordinator.

Statistics: We assume that a difference of 2 VAS-points is required for an effect to be of clinical interest. One-sided t-test for paired data will be used in the analysis.

Power calculation using the statistics program SSD v7.0 has shown that 16 participants is required to demonstrate a difference of 2 points at level of significance p=0.01, 90% power and assumed standard deviation of 2.
