Scoliosis is a musculoskeletal disorder defined by a three-dimensional spinal deformity that can result in substantial clinical and functional limitations, particularly during adolescence and young adulthood. Affected individuals commonly experience postural asymmetry, muscular imbalance, pain, and diminished quality of life. In conservative management, Physiotherapeutic Scoliosis-Specific Exercises (PSSE) have gained recognition as a fundamental intervention. The primary objectives of PSSE include optimizing spinal alignment, facilitating rotational breathing, and restoring muscular symmetry to improve functional capacity. Evidence from systematic reviews suggests that PSSE, especially the Schroth method, are superior to general exercise programs in improving both radiographic parameters and health-related quality of life.Meta-analytic findings further support the effectiveness of PSSE in reducing curve magnitude and enhancing quality of life outcomes. Among the various PSSE approaches, the Schroth method is one of the most extensively investigated and widely applied in clinical settings. This method incorporates three-dimensional postural correction, targeted breathing techniques, and the development of postural awareness. Randomized controlled trials have demonstrated that Schroth exercises significantly improve SRS-22 quality of life scores and positively influence pain, body image, and overall well-being.Despite these established benefits, pain and muscle tension occurring during exercise sessions may negatively influence adherence to rehabilitation programs. In young adults, pain is a critical factor limiting treatment compliance and restricting engagement in daily activities. Accordingly, adjunctive interventions implemented prior to exercise may enhance exercise tolerance and optimize therapeutic outcomes.Peloidotherapy, which involves the therapeutic application of natural medicinal mud, is commonly used in musculoskeletal rehabilitation due to its analgesic, muscle-relaxant, and circulation-enhancing effects. By alleviating pain and reducing muscular tension, peloidotherapy may facilitate greater participation in exercise programs and support improved clinical outcomes.This study aims to investigate the effects of adjunctive peloidotherapy administered before Schroth-based PSSE in young adults with scoliosis, focusing on pain, exercise adherence, and quality of life, with particular emphasis on SRS-22 measures..
