Neuromodulation of the Dorsal Genital Nerve in Persistent Genital Arousal Disorder

Not Applicable

Completed

• Conditions: Arousal Disorders, Sexual

• Registration Number: NCT06790563
• Lead Sponsor: Radboud University Medical Center

Brief Summary

The goal of this clinical trial is to learn if neuromodulation of the dorsal genital nerve works to treat symptoms related to Persistent Genital Arousal Disorder in women. The main questions it aims to answer are:

What is the effect of neuromodulation on PGAD symptoms in women?

Participants will:

Use a neurosimulator every day for 3 weeks. Keep a diary of their symptoms and the number of times they used the neurostimulator Fill in questionaires

Primary Outcome Measures

Name	Time	Method
Symptom severity	8 weeks	Symptom severity on a 5-point Likert scale, filled in daily. 1 indicates no symptoms at all, 5 indicates very severe symptoms.
Neuromodulation effect	3 weeks	The neuromodulation effect will be assessed using a self-reported diary, where participants are prompted daily to rate their experience of symptoms in response to the question: "How do you experience your symptoms today?" Responses are recorded on a 5-point Likert scale with the following options: "No problem," "Mild," "Moderate," "Severe," or "Very severe." This dairy is quaried during the three weeks intervention period, in which the participants use the neuromodulator device daily.
Satisfaction device	At the end of the treatment, at week 8	The consideration of using the neuromodulator device as part of their treatment, which was asked at the end of the treatment with the question "Would you like to continue using the device as part of your treatment". Following with a 'Yes' or 'No' answer.

Secondary Outcome Measures

Name	Time	Method
HADS	At baseline, at the end of the intervention (week 3) and at the end of post-intervention (week 8)	Hospital Anxiety and Depression Scale, measuring the level of anxiety and depression, both scores ranging from 0 to 21: 0-7 : no anxiety disorder or depression 8-10 : possible anxiety disorder or depression 11-21: suspected anxiety disorder or depression
PCS	At baseline, at the end of the intervention (week 3) and at the end of post-intervention (week 8)	Pain Catestrophizing Scale. Score ranging from 0 to 52, in which a higher score indicates a higher level of pain catestrophizing.
QoL	At baseline, at the end of the intervention (week 3) and at the end of post-intervention (week 8)	Quality of Life measured with the EQ-5D-3L (EuroQol-5 Dimensions-3 Levels). The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state.; The EQ VAS records the patient's self-rated health on a vertical visual analogue scale where the endpoints are labelled 'Best imaginable health state' and 'Worst imaginable health state'. Higher EQ VAS score indicated higher self-related health.
Patient Global Impression of Improvement	During follow-up (after week 8)	Patient Global Impression of Improvement (PGI-I) is a scale to rate the patients condition now, as compared with how it was prior to before beginning treatment on a scale from 1. Very much better to 7. Very much worse.
