Overview
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.
Description
Shoulder tendinopathies are a common cause of pain, functional limitation, and reduced quality of life, with a significant impact on daily activities. Their clinical presentation is heterogeneous, involving not only structural and functional impairments but also activity limitations and participation restrictions.
Conservative management remains the first-line approach and typically includes multimodal rehabilitation programs incorporating balneophysiotherapy, exercise therapy, and physical modalities. Although these interventions are widely used and have demonstrated clinical benefits, the optimal combination of therapeutic modalities remains a subject of ongoing research.
Pulsed electromagnetic field (PEMF) therapy delivered via the Super Inductive System (SIS) is a non-invasive intervention with potential analgesic, neuromodulatory, and regenerative effects. However, evidence regarding its additional benefit when integrated into standard multimodal rehabilitation programs for shoulder tendinopathies is still limited.
Given the multifactorial nature of shoulder tendinopathies, a multidimensional assessment approach is required. This study is based on the framework of the International Classification of Functioning, Disability and Health (ICF) and aligned with OMERACT recommendations, allowing a comprehensive evaluation of clinical outcomes across multiple domains.
The aim of this study is to compare the effectiveness of PEMF therapy delivered via SIS, integrated into a multimodal rehabilitation program, with standard balneophysiotherapy in patients with shoulder tendinopathies.
Participants are allocated to either a control group receiving standard treatment or an experimental group receiving the same rehabilitation program supplemented with PEMF (SIS) therapy. Clinical outcomes, including pain intensity, shoulder function, pressure pain threshold, muscle strength, psychological status, depressive symptoms, and quality of life, are assessed at baseline (admission), immediately after treatment completion (discharge), and at 4 weeks after treatment.
This study seeks to determine whether the addition of PEMF (SIS) therapy provides superior outcomes within a multimodal rehabilitation strategy and supports a personalized, multidimensional approach to the management of shoulder tendinopathies.
