Effect of Pulsed Electromagnetic Field (PEMF) Therapy Delivered Via the Super Inductive System (SIS) Combined With Balneophysiotherapy in Patients With Shoulder Tendinopathies: A Randomized Controlled Trial
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.
• Adults aged between 18 and 70 years.
• Patients with chronic shoulder pain lasting more than 3 months, of non-traumatic origin, persistent despite prior conservative treatment.
• Clinical diagnosis of shoulder tendinopathy and/or subacromial pain syndrome based on medical history and physical examination.
• Presence of shoulder pain and functional limitation confirmed by clinical assessment and baseline functional evaluation (SPADI).
• Ability to comply with the treatment protocol and attend scheduled follow-up assessments.
• Provision of written informed consent prior to participation.
