Riassunto dello studio

Sixty-four patients with chronic low back pain were randomized to receive electrical dry needling (n=32) or a non-invasive multicomponent intervention (n=32). The primary outcome of interest was the pressure pain threshold. Secondary outcomes included pain on a Visual Analog Scale (VAS), Oxford Disability Index (ODI), Tampa Scale of Kinesiophobia (TSK), Roland-Morris Low Back & Disability (RMDQ) questionnaire, McQuade test, finger-to-floor distance, isometric endurance of trunk muscles, lumbar mobility in flexion, quality of life using the Short-Form 36 (SF-36) questionnaire, and quality of sleep. Outcomes were assessed at baseline, immediately post-treatment (6 weeks), and at 2 months. Overall, the results of the study revealed that electrical dry needling had more positive effects on pain intensity, disability, and kinesiophobia compared to the non-invasive intervention. These findings suggest that electrical dry needling may be more effective for managing chronic low back pain.
