Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Acute and subacute lumbosacral disc herniation with radiculopathy.
  • Positive Straight leg raising test or Slump test.

Exclusion criteria

Exclusion Criteria:

  • Spondylolisthesis, prior spinal surgery, "Red Flags" (Cauda Equina, ), or a non-mechanical response to repeated movements and patients with LBP without radiculopathy.
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Study arms

  • Experimental
    A) Extension bias, prone traction

    Mechanical intermittent traction will done for 15 minutes with patient in prone position, after release the patient let wrest for 2 minutes then asked to walking for 1 minutes without immediate sitting post traction period. Prone on elbow press up exercise . Infrared radiation on back before traction

    Other: group A

  • Experimental
    B) Extension bias, supine traction

    Mechanical intermittent traction will done for 15 minutes with patient in supine position, after release the patient let wrest for 2 minutes then asked to walking for 1 minutes without immediate sitting post traction period. Infrared on back before the traction. Press up on elbow exercise .

    Other: Group B

  • Experimental
    C) Flexion bias, supine traction

    Mechanical intermittent traction will done for 15 minutes with patient in supine position(matches flexion bias), after release the patient let wrest for 2 minutes then asked to walking for 1 minutes without immediate sitting post traction period. Infrared on the back before the traction for 10 minutes. Knee to chest exercise for 2 minutes before the session .

    Other: Group C

  • Experimental
    D) Flexion bias, prone traction

    Mechanical intermittent traction will done for 15 minutes with patient in prone position(mismatches flexion bias), after release the patient let wrest for 2 minutes then asked to walking for 1 minutes without immediate sitting post traction period. Infrared on the back before the traction for 10 minutes. Knee to chest exercise for 2 minutes before the session .

    Other: Group D

Interventions

  • Othergroup A

    Press up on elbow exercise traction from prone.

  • OtherGroup B

    Press up on elbow exercise. traction from supine

  • OtherGroup C

    Traction from supine with flexion bias exercise knee to chest exercise for 2 minutes

  • OtherGroup D

    Traction from prone with flexion bias exercise knee to chest exercise for 2 minutes

What researchers measure

Primary outcomes

  1. Numerical pain scale (NPRS)

    Pain (lower limb radiating pain)

    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)

  2. Oswestry back scale (ODI)

    Functional questionnaire for back disability

    Time frame: 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)

  3. Hip flexion Angle

    Hip flexion Angle during SLR test is also used to measure neural tension improvements for extension bias groups (by digital inclinometer)

    Time frame: Hip flexion Angle was assessed at baseline (during the initial assessment) and again after completion of the 12th treatment session (one-month follow-up)

  4. 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).

    Time frame: Knee extension angle was assessed at baseline (during the initial assessment) and again after completion of the 12th treatment session (one-month follow-up)

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Sep 2026; primary completion for Oct 2026, 1 month later.

Of 203 non-industry interventional studies with no phase under Radiculopathy, half reached primary completion within 11 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 30. This study's planned 1 month is below that.

Counting every sponsor, half of 215 studies reached it within 12 months; a quarter within 5 and three quarters within 45.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 26, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
