Eligibility
Inclusion criteria
Inclusion criteria: Individuals of both genders; age between 18 and 80 years; low back pain lasting more than 12 weeks, located between the 12th rib and the inferior gluteal fold; pain intensity = 4/10 on the Numeric Pain Rating Scale (NPRS) in the week prior to baseline assessment; presence of at least one active myofascial trigger point in the lumbopelvic musculature (gluteus medius, gluteus maximus, quadratus lumborum or lumbar paraspinal muscles L1–L5), confirmed by the three clinical criteria of the Delphi consensus by Fernández-de-las-Peñas and Dommerholt (2018); written informed consent
Exclusion criteria
Exclusion criteria: History of previous lumbar spine surgery; presence of signs or symptoms of radiculopathy or neurological impairment; diagnosis of specific spinal pathologies (fracture, tumor, infection or inflammatory diseases); pregnancy; use of analgesic or anti-inflammatory medication within 48 hours prior to assessment; participation in another physiotherapy treatment program for low back pain during the study period; inability to understand or follow study instructions
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| It is expected to observe a reduction in low back pain intensity, assessed using the Numeric Pain Rating Scale (NPRS 0–10), based on comparisons across time points T0 (baseline), T1 (post-intervention), T2 (3 months), and T3 (6 months), with a minimum clinically important between-group difference of at least 2.0 points | — |
Secondary
| Measure | Time frame |
|---|---|
| It is expected to observe a reduction in functional disability, assessed using the Roland-Morris Disability Questionnaire (RMDQ 0–24 points), based on comparisons across time points T0, T1, T2, and T3;It is expected to observe an improvement in global perceived effect, assessed using the Global Perceived Effect Scale (GPE -5 to +5), based on comparisons across time points T1, T2, and T3;It is expected to observe an increase in pressure pain threshold at the lumbar region, assessed using digital algometry (MedEor®, kg/cm²) at bilateral paraspinal points at L4 and L5, based on comparisons across time points T0, T1, T2, and T3;It is expected to observe an increase in remote pressure pain threshold, assessed using digital algometry (MedEor®, kg/cm²) at the right tibialis anterior muscle, based on comparisons across time points T0, T1, T2, and T3;It is expected to observe an increase in lumbar extensor muscle endurance, assessed using the Biering-Sorensen test (seconds), based on comparisons across time points T0, T1, and T3 | — |
