Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The pathophysiology underlying rotator cuff-related shoulder pain continues to be a subject of ongoing research and uncertainty, with many aspects yet to be fully elucidated. The most common belief regarding its pathogenesis involves the role of inflammation. This hypothesis is supported by the accumulation of inflammatory cells in tendons, oxidative stress, and increased levels of pro-inflammatory cytokines. In tendon pathologies with inflammatory cell accumulation and increased cytokine levels, the use of antioxidants and anti-inflammatory agents in addition to conservative treatment contributes to tendon healing. Anti-oxidants and anti-inflammatories are substances capable of preventing or delaying certain cell damage.The use of anti-inflammatory and antioxidant supplements such as Vitamin C (Vit-C), Vitamin D (Vit-D), Omega-3, and Magnesium (Mg) is recommended. Despite indicating exercise as the gold standard for managing rotator cuff-related shoulder pain and the demonstrated anti-inflammatory and anti-oxidant properties of the mentioned supplements, there are still gaps in the understanding of their effectiveness in rotator cuff-related shoulder pain.
Based on these gaps, the goal of this study is to investigate the effects of supplements (Vit-C, Vit-D, Omega-3, and Mg) given in addition to exercise on patients' blood parameters (TNF-a, IL-6, and CRP levels), pain, functional status, quality of life, and patient satisfaction in individuals with rotator cuff-related shoulder pain.
