About this study
Official title: Effectiveness of Neurodynamic Sliding Mobilisation in the "Slump" Position in Relation to the Perceptible Pain Threshold in Asymptomatic People, a Cross-over Randomised Controlled Trial
According to the French National Health Agency, the use of manual therapy techniques is "possible" [grade B] as part of a multimodal combination of treatments for low back pain. These include so-called "neurodynamic" neural mobilisations, which aim in particular to desensitise the pain system and activate descending inhibitory pathways, with effects on pain and function in patients with nerve-related low back pain. Most of the available evidence does not explain the mechanisms involved in neural mobilisation in the slump position. Pain reduction is observed in more areas of the body with sliding techniques than with traction techniques.
In this cross-over, randomised controlled trial, we therefore hypothesise that the neurodynamic sliding technique in the slump position acts on mechanisms linked to central pain modulation processes

What is being measured
The primary outcome is the main question the study is designed to answer.
Difference in pressure at the moment when the volunteer indicates that the sensation of pressure becomes pain
Difference in pressure exerted on the territory of the sciatic nerve (gluteal region) at the moment when the volunteer indicates that the sensation of pressure becomes pain, on the dominant lower limb, between the same volunteer during two treatment sessions which differ only in the exposure to neurodynamic sliding mobilisation in the "Slump" position or to mobilisation outside the "Slump" position.
Measured: immediately after the mobilisation and 1 day after the mobilisation

Questions about this trial
What is this clinical trial studying?
A study testing "slump"position and no" slump" position in people with Voluntary, run by University Hospital, Rouen 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 7 inclusion and 6 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 7 May 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. Some participants in this study may receive a placebo. 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 timothée GILLOT, PhD (0232880671 ext. +33, timothee.gillot@chu-rouen.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Difference in pressure at the moment when the volunteer indicates that the sensation of pressure becomes pain (time frame: immediately after the mobilisation and 1 day after the mobilisation). 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 7 May 2026; AzTrials last refreshed its copy on 8 Nov 2026.
