Clinical Trial Summary

Primary dysmenorrhea is defined as lower abdominal pain that occurs during menses and is not secondary to any type of pelvic disease. It is considered the most common condition in reproductive age women. First line of treatment are non-steroidal anti-inflammatory drugs (NSAIDS), or oral contraceptives (OCC). This two forms of treatment have not demonstrated 100% efficacy, and adverse events and contraindications for both exist. Moreover, studies have demonstrated that an important women do not use, or don't like to use, pharmacological treatment. Music have demonstrated analgesic effects in different clinical contexts, and has emerged as an important form of complementary therapy in the management of pain. To the researcher's knowledge, no studies have been conducted to evaluate music's effectiveness in pain secondary to primary dysmenorrhea.

The following is the protocol for a randomized, single blinded, clinical trial, where an experimental group listened to a 30 minute song, and was compared to a control group that rest in silence for the same time and conditions. It was expected that music will produce a larger, and significant, effect on pain reduction when compared to the control silence group according to pain measured through a 10 cm Visual Analogue Scale (VAS) in young women from the School of Medicine and Health Sciences at the Universidad del Rosario, Bogota DC, Colombia. Additionally, the investigators wanted to evaluate the clinical effect of music and analgesic requirements, anxiety and vital signs were also measured.

Description:

Primary Dysmenorrhea (PD) is defined as pain in the lower abdomen, that occurs always during menses, in the absence of pelvic pathology, and lasts about 24-72 hours. It initiates during the first 24 months after menarche. Other symptoms like, emotional lability, anxiety, nausea, headache, and others may accompany the pain. It is considered the most common condition of reproductive age women, and is considered one of the most important causes for school or work absence in this population.

Music has been proposed as a complementary therapy for the management of pain, and a large body of clinical evidence supports its use on clinical context. Additionally, functional imaging research has found that music activates areas related to pain modulation and perception like the periaqueductal gray matter. Moreover music seems to modify brain activity during pain perception. Music has been shown to be effective in relieving pain secondary to surgery, in cancer related pain, and other types of pain, but it has not been studied for primary dysmenorrhea.

This randomized clinical trial was designed with the following objectives

General Objective: To evaluate the efficacy of music listening, compared to a control group that rested in silence, in the painful experience secondary to primary dysmenorrhea in women of 18 years or older from the School of Medicine and Health Sciences at the Universidad del Rosario, Bogotá DC., Colombia.

Specific Objectives:

1. Description of demographic data, clinical, gynecological, and obstetric background from the study population.

2. Description of pain management, secondary to PD, used by the study population.

3. Evaluate the usual pain secondary to PD, as reported by the study participants through a Visual Analogue Scale (VAS)

4. To explore if the acute perception of pain secondary to PD, as reported by participants using a VAS, before the intervention, is different between the study groups.

5. To evaluate if the acute perception of pain secondary to PD, as reported by participants using a VAS, after the intervention, differs between those that listened to music and those that rested in silence.

6. To explore if a difference in the reduction of pain, as reported by participants using a VAS, from the moment before to the moment after the intervention exists between those in the music group compared to those in the silence group.

7. To evaluate if the acute perception of pain secondary to PD, as reported by participants using a VAS, 3-6 hours after the intervention, differs between those that listened to music and those that rested in silence.

8. To evaluate if the anxiety secondary to PD, as reported by participants using a validated Spanish short version of the Zung scale, differs between groups, before and after the intervention.

9. To evaluate if a difference in the reported requirements of analgesic drugs is different between the study groups after and 3-6 hours after the intervention.

10. To evaluate if a difference in heart rate, systolic and diastolic blood pressure is identified between groups, using a previously calibrated digital sphyngmomanometer.

The investigators hypothesized that listening to an instrumental song, unknown to the patient, will have a significant effect on pain relief. Additionally, investigators hypothesized that music listening will have a clinical effect big enough to also impact analgesic requirements and anxiety scores .

Primary endpoint was pain reduction from the moment before to after the intervention. Pain reduction is the better way to evaluate analgesia efficacy and was the proper approach for these protocol's main objective, which was efficacy of music on pain relief secondary to primary dysmenorrhea.

For achieving these aims and answering research questions, a randomized clinical trial was designed. As patients can't be blinded from listening or not to music, a single blinded approach was decided. Furthermore, methodology for recruitment was designed to blind patients from allocation until the day of the intervention and a speech was used to avoid patients to identify the primary endpoint. Additionally, patients were explained that two interventions were used, but it was not specified that silence group was the control group, to assure proper blinding and avoid further bias of results. Silence was decided as a control intervention as comparison with drug placebo may not be adequate due to differences in the types of intervention.

To isolate the music effects the investigators decided on using a completely new and unknown song. The song was planned and composed exclusively for the research, so all patients allocated to the music group listened to the exact same musical piece.

Intervention

Behavioral:
• Music group
The song was composed on a C major scale and a 60 bpm tempo. The song was composed with high consonance using simple melodic progressions on the C major scale, and using natural positions for chords. No percussion or lyrics were used for the song, and the following instruments were used in the composition: electric guitar and keyboards, violin (digital), cello (digital), clarinet (digital), synthesizers (digital), and fretless bass (digital).
• Silence Group
Audio file that contained no sounds.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Pain From 1-5 Minutes Before (Baseline) to 1- 5 Minutes After the Intervention	Pain scores were measured using a visual analogue scale (VAS) of 10 cm (0 no pain at all, and 10 the worst possible pain) at each time point. Main outcome was calculated from the difference between visual analogue score at 1-5 minutes after (VAS3) minus visual analogue score at 1-5 minutes before the intervention (VAS2).	From 1-5 minutes before the intervention (baseline) to 1-5 minutes after the intervention.
Secondary	Usual Pain Associated to Menses	Mean pain scores measured with a 10 cm visual analogue scale (VAS) where 0 was no pain at all and 10 the worst possible pain. Usual pain was evaluated before the intervention and was known as VAS 1.	5-10 minutes before the intervention.
Secondary	Actual Pain 1-5 Minutes Before the Intervention (Baseline).	Mean pain scores measured with a 10 cm visual analogue scale (VAS) where 0 was no pain at all and 10 the worst possible pain. Actual pain was evaluated immediately before the intervention and was known as VAS 2.	1-5 minutes before the intervention.
Secondary	Actual Pain 1-5 Minutes After the Intervention.	Mean pain scores measured with a 10 cm visual analogue scale (VAS) where 0 was no pain at all and 10 the worst possible pain. Actual pain was evaluated immediately after the intervention was completed, and was known as VAS 3.	1-5 minutes after the intervention.
Secondary	Actual Pain 3-6 Hours After the Intervention.	Mean pain scores measured with a 10 cm visual analogue scale (VAS) where 0 was no pain at all and 10 the worst possible pain. Actual pain was evaluated 3-6 hours after the intervention was completed, and was known as VAS 4.	3-6 hours after the intervention.
Secondary	Anxiety Score Before the Intervention	Using a validated short spanish version of the Zung anxiety scale, anxiety was measured before the intervention. The scale was composed of 10 items. Each item had a 4 Likert point scale (0= never, 1= some times, 2= most of the time, and 3 = always). Final scores ranged from 0, minimum anxiety, and 30 maximum anxiety.	1-5 minutes before the intervention.
Secondary	Anxiety Score After the Intervention	Using a validated short spanish version of the Zung anxiety scale, anxiety was measured after the intervention. The scale was composed of 10 items. Each item had a 4 Likert point scale (1= never, 2= some times, 3= most of the time, and 4 = always). Scores ranged from 10, minimum anxiety, and 40 maximum anxiety. For analysis, mean quantitative scores were obtained so 1 was equivalent to minimum anxiety, and 4 to maximum anxiety.	1-5 minutes after the intervention.
Secondary	Anxiety Score 3-6 Hours After the Intervention	Using a validated short spanish version of the Zung anxiety scale, anxiety was measured 3-6 hours after the intervention. The scale was composed of 10 items. Each item had a 4 Likert point scale (0= never, 1= some times, 2= most of the time, and 3= always). Scores ranged from 0, minimum anxiety, and 30 maximum anxiety.	3-6 hours after fter the intervention.
Secondary	Analgesic Requirements Before	Before the intervention patients were asked if they wanted to use any analgesic drug or do any kind of analgesic strategy. Patients simply answered yes or no.	1-5 minutes before the intervention the intervention.
Secondary	Analgesic Requirements After	After the intervention patients were asked if they wanted to use any analgesic drug or do any kind of analgesic strategy. Patients simply answered yes or no.	1-5 minutes after the intervention.
Secondary	Analgesic Use During a Period of 3-6 Hours After the Intervention.	After the intervention, all patients had to register all analgesic drugs (e.g. ibuprofen) or strategy (e.g. local heat) that were used until last pain measurement (VAS 4, 3-6 hours after the intervention).	3-6 hours after the intervention)
Secondary	Systolic Blood Pressure Before the Intervention	Systolic blood pressure in mmHg measured with a calibrated digital sphygmomanometer before the intervention.	1-5 minutes before the intervention.
Secondary	Diastolic Blood Pressure Before the Intervention	Diastolic blood pressure in mmHg measured with a calibrated digital sphygmomanometer before the intervention.	1-5 minutes before the intervention.
