What is being measured
The primary outcome is the main question the study is designed to answer.
Numerical pain scale (NPRS)
Pain (lower limb radiating pain)
Measured: Pain intensity was assessed at baseline (during the initial assessment) and again after completion of the 12th treatment session (one-month follow-up)
Oswestry back scale (ODI)
Functional questionnaire for back disability
Measured: Patients completed the ODI questionnaire at baseline during their initial clinical evaluation. A subsequent assessment was conducted upon completion of the 12-session intervention protocol (representing the one-month follow-up)
Hip flexion Angle
Hip flexion Angle during SLR test is also used to measure neural tension improvements for extension bias groups (by digital inclinometer)
Measured: Hip flexion Angle was assessed at baseline (during the initial assessment) and again after completion of the 12th treatment session (one-month follow-up)
Knee extension angle
Knee extension angle with active knee extension during slump test was used for flexion bias groups (to measure how many degrees the knee is away from full extension when the leg pain starts).
Measured: Knee extension angle was assessed at baseline (during the initial assessment) and again after completion of the 12th treatment session (one-month follow-up)

Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 26 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.
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 Atef abdulalim nadier, Assistant professor (+201003867064, a.nadier@ammanu.edu.jo), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Numerical pain scale (NPRS) (time frame: Pain intensity was assessed at baseline (during the initial assessment) and again after completion of the 12th treatment session (one-month follow-up)). The study lists 4 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 26 Aug 2026.
