Descrição detalhada
Chronic mechanical low back pain is a common musculoskeletal condition that leads to functional disability and diminished quality of life. While focal extracorporeal shock wave therapy (F-ESWT) has emerged as a non-invasive treatment option to promote tissue regeneration and modulate inflammation, clinical protocols lack precise standardization regarding energy density and session distribution.
This randomized, double-blind clinical trial aims to analyze the clinical effects of two specific dosing regimens of F-ESWT. Eligible participants from the Physical Medicine and Rehabilitation Service will be randomly allocated to either Group A or Group B. Both groups will undergo targeted applications to the lumbar region using predefined therapeutic parameters detailed in the protocol.
Clinical evaluations will be performed at baseline and during post-treatment follow-up periods. Pain intensity, functional disability, and localized mobility will be measured using validated clinical tools to define which dosing scheme optimizes short-term and mid-term patient recovery.

Descrição
Inclusion Criteria:
- Individuals of both sexes.
- Age between 18 and 65 years.
- Clinical diagnosis of mechanical chronic low back pain (cLBP), defined as pain localized between the lower costal margin and the gluteal fold, with at least 12 weeks of evolution.
- Lumbar pain intensity of at least 5/10 on the Numeric Pain Rating Scale (NPRS).
- Predominantly mechanical pain, exacerbated by activities such as prolonged standing, trunk movements, extension, or lumbar rotation, and without clinical data of predominant radicular pain.
- Plain radiograph of the lumbar spine available as part of the baseline evaluation.
- Ability to attend all 4 treatment sessions and subsequent follow-up evaluations.
- Signed informed consent form previously approved by the Institutional Review Board / Research Ethics Committee.
Exclusion Criteria:
- Low back pain of probable non-mechanical origin or secondary to a specific cause that substantially modifies clinical management.
- Clinical data of predominant lumbar radiculopathy, including pain radiating below the knee with a dermatomal distribution, focal motor deficit, objective sensory alterations, or compatible reflex changes.
- Diagnosis or suspicion of cauda equina syndrome.
- History of previous lumbar spine surgery.
- Current vertebral fracture or recent history of lumbar fracture.
- Spondylolisthesis grade II or higher.
- Significant structural scoliosis or severe lumbar deformity that prevents treatment standardization.
- Suspicion or evidence of a tumor, infection, spondylodiscitis, or axial inflammatory disease.
- Severe clinically documented osteoporosis or history of vertebral fragility fracture.
- Pregnancy or lactation.
- Coagulation disorder, use of anticoagulants at therapeutic doses, or a hemorrhagic condition that increases procedure risk.
- Previous epidural infiltration, facet block, radiofrequency, or other lumbar interventional procedure within a recent period defined by the protocol.
- Current treatment with another physical rehabilitation modality or instrumental therapy directed at low back pain, if it cannot be suspended during the intervention period.
- Current use of nonsteroidal anti-inflammatory drugs (NSAIDs) that the patient cannot suspend according to the study indications.
- Concomitant neurological, rheumatological, oncological, or musculoskeletal disease that significantly interferes with pain or disability evaluation.
- Cognitive impairment, decompensated psychiatric disorder, or any condition that prevents understanding instructions, answering questionnaires, or completing follow-up.

Armas e Intervenções
Grupo de Participantes / Braço |
Intervenção / Tratamento |
|---|---|
|
Experimental: Group A: Regimen 1
Participants in this group will receive focal extracorporeal shock wave therapy (F-ESWT) administered to the lumbar region using the first specific dosing scheme, characterized by designated energy flux density and session frequency parameters as outlined in the protocol.
|
Non-invasive shock wave therapy applied to specific painful lumbar points using the BTL-6000 FSWT focused shockwave device.
The equipment delivers focused acoustic energy to modulate localized pain and stimulate tissue response, according to the designated dosing regimens established in the study protocol.
|
|
Experimental: Group B: Regimen 2
Participants in this group will receive focal extracorporeal shock wave therapy (F-ESWT) administered to the lumbar region using the second specific dosing scheme, characterized by alternative energy flux density and session frequency parameters as outlined in the protocol.

O que o estudo está medindo?
Medidas de resultados primários
Medida de resultado |
Descrição da medida |
Prazo |
|---|---|---|
|
Change from Baseline in Pain Intensity on the Visual Analog Scale (VAS)
Prazo: Baseline, 2 months, 4 months, 6 months, and 12 months post-treatment
|
Pain intensity will be evaluated using a 100-mm Visual Analog Scale (VAS), where 0 mm represents "no pain" and 100 mm represents "the worst possible pain".
Higher scores indicate greater pain severity.
The outcome is measured as the change in millimeter scores from baseline to each subsequent post-treatment follow-up assessment.

Change from Baseline in Lumbar Functional Disability Using the Oswestry Disability Index (ODI)
Prazo: Baseline, 2 months, 4 months, 6 months, and 12 months post-treatment
|
Functional disability associated with mechanical low back pain will be measured using the Oswestry Disability Index (ODI).
The questionnaire consists of 10 items assessing limitations in daily activities.
Total scores range from 0% (no disability) to 100% (maximum disability).
Higher percentages reflect greater functional impairment.
|
Baseline, 2 months, 4 months, 6 months, and 12 months post-treatment
|
|
Incidence of Treatment-Related Adverse Events
Prazo: From the first treatment session up to 12 months post-treatment
|
Safety and tolerability will be evaluated by monitoring and recording the frequency, severity, and type of any localized adverse events associated with focal extracorporeal shock wave therapy (F-ESWT), such as transient erythema, mild bruising, or temporary pain increase.
|
From the first treatment session up to 12 months post-treatment
