Dry Needlig Vesus Tecartherapy in Low-back Pain Treatment

Introduction: Diathermy is a new tool that could help subjects with chronic low back pain (CLBP), with no studies having compared it to other interventions already investigated such as dry needling.

Hypothesis: Diathermy is more effective than dry needling in improving pain intensity in the short term in subjects with CLBP.

Design: randomised controlled trial Methods: We will conduct a convenience sampling, with subjects receiving 2 treatment sessions with diathermy or dry needling, according to allocation. Subjects will be assessed at baseline, 1 week, 1 month and 3 months after treatment for pain intensity, disability, kinesiophobia and catastrophizing. Analysis of variance (ANOVA) and moderation analysis will be performed to evaluate the results, with 95% confidence intervals (CI).
