About this study
Official title: Effect of MLS® Class IV Laser Photobiomodulation on Chronic Pain and Fatigue in Hypermobile Ehlers-Danlos Syndrome: A Prospective Observational Pilot Study in Private Medical Practice
This study evaluates the effect of photobiomodulation (PBM) therapy using a MLS® class IV laser on chronic pain and fatigue in patients with hypermobile Ehlers-Danlos Syndrome (hEDS). hEDS is a hereditary connective tissue disorder characterized by joint hypermobility, chronic pain, and debilitating fatigue, for which therapeutic options remain limited.
Participants will receive 10 PBM sessions over 5 weeks (2 sessions per week), using red and near-infrared light (808 nm continuous + 905 nm pulsed) applied to painful areas identified at baseline. Pain (Visual Analogue Scale), multidimensional fatigue (MFI-20), and quality of life (EQ-5D-5L) will be assessed at baseline (T0), end of treatment (week 5), and follow-up (week 10).
This is a pilot observational study - the first to document the effect of MLS® laser PBM in hEDS. No additional procedures beyond routine care are required.
Read the detailed description
Background: Hypermobile Ehlers-Danlos Syndrome (hEDS) is the most common form of EDS (80-90% of cases), diagnosed according to the 2017 International Consortium criteria. Chronic pain and fatigue are the two most disabling symptoms. No randomized controlled trial has evaluated the effect of MLS® class IV laser photobiomodulation in hEDS to date.
Intervention: Photobiomodulation using ASAlaser M-Hi device (MLS® technology: synchronized 808nm continuous + 905nm pulsed emissions, CE MDR class IV). Progressive fluence: 4 J/cm² (sessions 1-2), 6 J/cm² (sessions 3-6), 8 J/cm² (sessions 7-10). Maximum 3-4 zones per session. Treatment areas individualized based on pain mapping at baseline.
Design: Single-center prospective observational pilot study in private practice. No randomization, no control group, no modification of ongoing treatment.
Statistical analysis: Wilcoxon signed-rank tests (paired, non-parametric), descriptive statistics. Exploratory pilot - no formal power calculation. Target sample size: 20-25 patients.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in chronic pain intensity
Change in pain intensity measured by the Visual Analogue Scale (VAS, 0-10), representing average pain over the preceding week. A decrease of ≥ 1.5 points is considered clinically meaningful.
Measured: Baseline (T0) to Week 5 (end of PBM treatment cycle)
Secondary outcomes (3)
Durability of pain relief
Change in pain intensity assessed by the Visual Analogue Scale (VAS, 0-10, where 0 = no pain and 10 = worst pain imaginable; lower scores indicate less pain), between end of treatment (Week 5) and follow-up (Week 10), to assess persistence of the analgesic effect after PBM cessation
Measured: Week 5 to Week 10 (5 weeks post-treatment follow-up)
Change in multidimensional fatigue
Change in fatigue assessed by the Multidimensional Fatigue
Inventory (MFI-20), comprising 20 items across 5 subscales:
General Fatigue, Physical Fatigue, Reduced Activity, Reduced Motivation, and Mental Fatigue. Total score ranges from 20 to 100.
Measured: Baseline (T0), Week 5 (T5), and Week 10 (T10)
Change in health-related quality of life
Change in quality of life assessed by the EQ-5D-5L questionnaire (5 dimensions: mobility, self-care, usual activities, pain/discomfort, anxiety/depression) and the EQ Visual Analogue Scale (EQ-VAS, 0-100).
Measured: Baseline (T0), Week 5 (T5), and Week 10 (T10)

Questions about this trial
What is this clinical trial studying?
An observational study of Ehlers-Danlos Syndrome, Hypermobile and Chronic Pain, run by Centre Medical ISM (Integrative Systemic Medicine) at 1 site in France.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 15 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Lilian Lessedjina, M.D. (+337-82-83-40-83, dr.llessedjina@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in chronic pain intensity (time frame: Baseline (T0) to Week 5 (end of PBM treatment cycle)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07637084, which also lists 3 linked publications.
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 15 Jun 2026.
