About this study
- Exercise-based treatment is part of the recommendations for good practice in the treatment of low back pain (acute, sub-acute and chronic).
- The low back pain population is heterogeneous. This heterogeneity would cause the positive effects of a treatment to be canceled out by the negative effects of another part of the population.
- This polymorphism has led several authors to classify low back pain into subgroups. These subgroups constitute more homogeneous clinical pictures and would facilitate the adaptation of treatments.
- The recommendations of the American Physical Therapy Association suggest 5 subgroups of low back pain. One of them is "low back pain with movement coordination defect". In this subgroup, Luomajoki studied the reliability of different functional tests used in clinical practice. 6 out of 10 motion control fault tests show good reliability.
- The quantified analysis of the movement of low back pain patients would make it possible to determine the sensitivity of detecting an anomaly in the 6 lumbar movement control tests.

- The recommendations of the American Physical Therapy Association suggest 5 subgroups of low back pain. One of them is "low back pain with movement control impairment". In this subgroup, Luomajoki studied the reliability of different functional tests used in clinical practice. 6 out of 10 motion control fault tests show good reliability.
- The quantified analysis of the movement of low back pain patients would make it possible to determine the sensitivity of detecting an anomaly in the 6 lumbar movement control tests.
LoBaCoM is a monocentric, exploratory prospective study.
The purpose is to define a kinematic (angular) threshold corresponding to an anomaly detected clinically by three therapists for each test.

Questions about this trial
What is this clinical trial studying?
A study of Chronic Low-back Pain, run by University Hospital, Brest 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 5 inclusion and 5 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 11 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 Vincent CREAC'H (+33(0)298017935, vincent.creach@univ-brest.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Range of compensation motion : "waiters bow" test (time frame: Day 0). The study lists 6 primary outcomes in all. 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 11 Jun 2026.
