PEMF Therapy in Shoulder Tendinopathy

Kurzzusammenfassung

The goal of this clinical trial is to evaluate whether pulsed electromagnetic field (PEMF) therapy delivered via the Super Inductive System (SIS), integrated into a multimodal rehabilitation program, improves pain, function, pressure pain threshold, muscle strength, psychological status, and quality of life in adults with shoulder tendinopathies. The main questions it aims to answer are: * Does the addition of PEMF (SIS) therapy reduce pain intensity and improve pressure pain threshold compared to standard balneophysiotherapy? * Does PEMF (SIS) therapy improve shoulder function, muscle strength, psychological status, and quality of life? The study will compare a multimodal rehabilitation program supplemented with PEMF (SIS) therapy to standard balneophysiotherapy to determine whether the addition of PEMF (SIS) provides superior clinical outcomes. Participants will: * Undergo a multimodal rehabilitation program including balneophysiotherapy * Be assigned to receive either standard treatment or treatment supplemented with PEMF (SIS) therapy * Be evaluated at baseline (admission), immediately after treatment completion (discharge), and at 4 weeks after treatment using validated clinical instruments assessing pain, function, pressure pain threshold, muscle strength, psychological status, depressive symptoms, and quality of life.
