Slump Lateral Bending Test Diagnostic Accuracy in Lumbar Radicular Pain

September 1, 2026 updated by: Fisiopoint Parma Physiotherapy

Diagnostic Accuracy of the Slump Lateral Bending Test for MRI-Confirmed Lumbar Radicular Involvement: A Multicenter Prospective Observational Study

This observational diagnostic accuracy study will evaluate the ability of the Slump Lateral Bending Test to identify patients with suspected peripheral neurogenic pain or neural mechanosensitivity. Adult participants will be assessed using clinical examination procedures, including the Slump Lateral Bending Test and other neurological and neurodynamic findings. Thes study aims to determine whether this test may help clinicians recognize patients in whom peripheral nerve involvement contributes to symptoms. The results may support clinical reasoning in physiotherapy and improve the assessment o patients with suspected neurogenic pain.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Adult patients with suspected peripheral neurogenic pain or neural mechanosensitivity who are referred for physiotherapy assessment will be considered for inclusion. Participants may present with symptoms such as pain, paresthesia, dysesthesia, or movement-related symptoms potentially associated with peripheral nerve involvement. Eligible patients will undergo a standardized clinical assessment including neurological and neurodynamic examination procedures, including the Slump Lateral Bending Test.

Description

Inclusion Criteria

  • Adults aged 18 years or older.
  • Patients with suspected peripheral neurogenic pain or neural mechanosensitivity.
  • Presence of symptoms potentially related to peripheral nerve involvement, such as:
  • pain;
  • paresthesia;
  • dysesthesia;
  • symptoms modified by neurodynamic positioning.
  • Ability to understand the study procedures and provide written informed consent.
  • Ability to undergo the clinical, neurological, and neurodynamic assessment procedures required by the study.

Exclusion Criteria

  • Age under 18 years.
  • Inability to provide informed consent.
  • Presence of severe neurological disease or central nervous system disorder that may interfere with clinical assessment.
  • Previous major surgery or trauma affecting the assessed body region, if it may compromise interpretation of the clinical tests.
  • Acute inflammatory, infectious, or systemic disease that may explain the symptoms or contraindicate clinical testing.
  • Severe pain or clinical condition preventing safe execution of the Slump Lateral Bending Test or other neurodynamic tests.
  • Pregnancy, if neurodynamic testing is considered inappropriate or not clinically indicated.
  • Inability to understand instructions or complete the assessment procedures.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Sensitivity and Specificity of the SLBT for MRI-Confirmed Lumbar Nerve Root Contact or Compression
Time Frame: At baseline
Sensitivity, specificity, positive predictive value, negative predictive value, likelihood ratios, and overall diagnostic accuracy of the Slump Lateral Bending Test will be calculated using lumbar MRI findings classified as nerve root contact or compression as the reference standard.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 23, 2026

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
June 15, 2029

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
