Impact of Magnetic Stimulation on Pain in Endometriosis Patients
A study testing Magnetic stimulation in people with Endometriosis, run by Kantonsspital Winterthur KSW.
Trial summary
Many women with endometriosis still experience pain despite surgical and medical treatment. Over-the-counter painkillers are usually helpful in alleviating this pain. But for some patients, these medications eventually stop working. Pain then dominates their daily life. Read more about this study

About this study
Official title: Pelvic Functional Magnetic Stimulation on Pain in Endometriosis Patients - a Prospective Non Randomised, Non-blinded Single Centre Observational Trial
Many women with endometriosis still experience pain despite surgical and medical treatment. Over-the-counter painkillers are usually helpful in alleviating this pain. But for some patients, these medications eventually stop working. Pain then dominates their daily life. In this study, we are investigating the effects of magnetic stimulation using the "Tesla chair" and whether it can alleviate their pain
Read the detailed description
Patients who are diagnosed with CPP and hypertonic pelvic floor as assessed in gynaecological exam will be asked to participate. Before start of the Tesla chair treatment VAS Score by PPAF will be assessed. After 6 treatments (after 3 weeks an intermediate doctor's consultation will rule out aggravation of CPP by treatment and if possible the next cycle of 6 treatments will be scheduled. After completion of 12 treatments the VAS Score will be reassessed and treatments' success evaluated in a doctor's consultation. We plan to re-evaluate sustaining success after 3 months after treatments completion

Magnetic stimulation using the Tesla-Chair
| Study group | Role | What they receive |
|---|---|---|
| Tesla-Chair | Experimental | Not described Receives: Device: Magnetic stimulation |
What is being measured
The primary outcome is the main question the study is designed to answer.
Decrease of PPAF-Score before and after treatment.
Relief of pain measured by changes in PPAF (Pelvic pain assessment form) score before and after the treatment. 0= no pain, 10 = unbearable pain
Measured: From enrollment to the end of tratment at end of week 7
Secondary outcomes (1)
Decrease of PPAF-Score before and after treatment.
Relief of pain measured by changes in PPAF (Pelvic pain assessment form) score before and after the treatment. 0= no pain, 10 = unbearable pain
Measured: From enrollment to 3 months after completion of treatment

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Decrease of PPAF-Score before and after treatment. (time frame: From enrollment to the end of tratment at end of week 7). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Dec 2025.
