Lumbosacral radicular pain Musculoskeletal Diseases
Conditions
Interventions
This study is a 52-week multicentre, two-parallel-group, assessor-blinded, double-sham-controlled, randomised noninferiority clinical trial with an embedded vanguard (internal pilot) phase, process ev
operationalised as the application of a high-velocity, low-amplitude thrust to the gluteal region, small oscillations of the lumbar spine flexion-distraction piece with contact on sacrum, and downward

Inclusion criteria
Inclusion criteria: Current participant inclusion criteria as of 20/06/2024: A patient will be eligible to participate in the trial if the following criteria are satisfied: 1. Aged 18 years of age and older 2. Consulting in general practice, telemedicine call centre, outpatient spine clinic, ED, or self-assesses with back or leg pain symptoms, and lumbosacral radicular pain or sciatica is suspected 3. At least moderate leg pain severity (=3 out of 10 on NRS) 4. A lumbar spine MRI assessment available from the past 12 months 5. Following standard clinical assessment, the diagnosis of radicular pain caused by disc herniation (RAPIDH) is confirmed by a chiropractor - RAPIDH criteria score of =9 out of 20 (simplified weighted score of clinical signs and symptoms predicting RAPIDH: patient-reported unilateral leg pain [3 points], monoradicular leg pain [6 points], positive straight leg raise (SLR) =60° (SLR is positive if typical leg pain is produced between 0° and 60°) or positive femoral nerve stretch test [4 points], unilateral muscle weakness [3 points], unilateral ankle or patellar reflex decrease [4 points]; sensitivity 95%, specificity 71%) 6. Can read and communicate in German or English 7. An active email address and internet access via a mobile phone or computer Previous participant inclusion criteria: A patient is eligible to participate in the trial if the following criteria are satisfied: 1.

Exclusion criteria
Exclusion criteria: Current participant exclusion criteria as of 20/06/2024: A patient will not be eligible to participate in the trial if any of the following criteria apply: 1. Suspected serious spinal pathology or ‘red flags’ (e.g., cauda equina syndrome, progressive or widespread neurological deficit, spinal cord compression, suspicion of malignancy, infection, fracture, inflammatory spondyloarthropathy) 2. A history of lumbar spine surgery 3. A history of corticosteroid injection for sciatica symptoms in the past 4 weeks 4. Currently receiving ongoing care from a chiropractor for the same problem 5. Serious comorbidity preventing them from attending a research clinic or being able to undergo assessments and interventions 6. Pregnant or breastfeeding, or suspicion of pregnancy 7. A contraindication for spinal manual therapy (congenital spine anomalies, spinal infection, spinal tumour, spinal fracture) 8. A contraindication for corticosteroid nerve root injection (allergy to contrast medium, severe diabetes, oral anticoagulation that cannot be paused) 9. Already taking part in another research study related to back and/or leg pain Previous participant exclusion criteria: A patient is not eligible to participate in the trial if any of the following criteria apply: 1.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Leg pain impact measured using the pain intensity, enjoyment of life, and general activity (PEG) scale (0 to 10) at baseline, 4, 8, 12, 26, and 52 weeks. The primary endpoint is leg pain impact assessed at 12 weeks after randomisation. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Overall back and leg pain impact is measured using the PEG scale at baseline, 4, 8, 12, 26, and 52 weeks. 2. Time to resolution of sciatica symptoms measured on a 6-point ordered categorical scale. Data will be collected by weekly SMS text messages for the first 3 months, then from months 4 to 12 the SMS data collection will change to monthly, or until patients report on two consecutive occasions that they have recovered. 3. Prognostic risk status as measured by the STarT Back (low/medium/high risk of poor outcome) at baseline, 12, 26, and 52 weeks. 4. Back pain disability/function as measured by the Oswestry Disability Index (ODI, 0 to 100) at baseline, 4, 8, 12, 26, and 52 weeks. 5. Sciatica symptoms as measured by the Sciatica Bothersomeness Index (SBI, 0 to 24) at baseline, 4, 8, 12, 26, and 52 weeks. 6. Sleep problems as measured by the Jenkins Sleep Scale (JSS-4, 0 to 20) at baseline, 4, 8, 12, 26, and 52 weeks. 7. Fear of movement as measured by the Tampa Scale for Kinesiophobia (TSK-11, 11 to 44) at baseline, 4, 8, 12, 26, and 52 weeks. 8. Pain catastrophizing as measured by the Pain Catastrophizing Scale (PCS-6, 0 to 24) at baseline, 4, 8, 12, 26, and 52 weeks. 9. Anxiety and depression as measured by the Hospital Anxiety and Depression Scale (HADS, 0 to 42) at baseline, 4, 8, 12, 26, and 52 weeks. 10. Pain self-efficacy as measured by the Pain Self-Efficacy Questionnaire (PSEQ-4, 4 to 24) at baseline, 4, 8, 12, 26, and 52 weeks. 11. Consultation-based reassurance as measured by the Consultation Reassurance Questionnaire (CRQ-12, 0 to 54) at baseline, 4, 8, and 12 weeks. 12. Therapeutic alliance as measured by the Working Alliance Inventory - short revised (WAI-SR, 12 to 60) at 4 weeks. 13. General health as measured by a self-rated general health item from the WHO 5-point ordinal scale at baseline, 4, 8, 12, 26, and 52 weeks. 14. Health-related quality of life as measured by the utility-based quality of life (EQ-5D-5L) at baseline, 4, 8, 12, 26, a | — |
