Summary
Study Background and Purpose Tendinopathies are common and debilitating musculoskeletal disorders that often lead to chronic pain and reduced mobility. Traditional treatments face challenges due to limited tendon blood supply, leading to poor healing. This study investigates ultrasound-guided galvanic electrolysis therapy (USGET), which uses electric current to promote tendon healing, comparing its efficacy with a placebo. Objectives The primary goal is to assess pain reduction, while secondary goals evaluate functionality, elasticity, and morphological changes (imaging) in patients with patellar tendinopathy. Methodology * Design: Prospective, randomized, double-blind, placebo-controlled study. * Duration: 24 months (October 2024 - October 2026). * Groups: * Intervention Group: Electrolysis therapy with galvanic current, Progressive tendon-loading exercises. * Control Group: Electrolysis placebo (without current), Progressive tendon-loading exercises. * Sample Size: 74 subjects. * Data Collection: Baseline, post-treatment (4 months), and follow-up (7 months). Evaluation and Data Analysis The study assesses pain via VAS and functionality scores, alongside imaging (MRI, sonography) to measure tendon morphology. Statistical analysis includes hypothesis testing and regression using SPSS software. Ethics and Publication Ethics approval is from the Bremen Medical Chamber. Results will be published regardless of outcome, following Good Clinical Practice and the Declaration of Helsinki.
