High Induction Magnetic Field Therapy is a therapeutic method that uses high-intensity fields (up to 2.5 T) that produce high current density in exposed tissue. While there are studies in the literature on devices with 2.5 T, there is no research on the effect of 4 T. Magnetic field application contributes significantly to the healing process. It is an easier, cheaper, and more comfortable application. The magnetic field has been clinically proven to be safe. It is a practical, non-invasive method to induce cell and tissue modifications, correcting selected pathological conditions through magnetic application. The aim of the study is to investigate whether High Induction Magnetic Field therapy applied in addition to conservative treatment in patients with shoulder pain makes a difference compared to conservative treatment alone.

It is planned to include people between the ages of 18-65 in the study. Before the evaluation, written consent will be obtained from the participants and information on their age, gender, weight, height, chronic disease and medication use, presence of previous surgical operations, daily activity frequency, alcohol or cigarette use will be obtained.

Individuals who voluntarily agree to participate in the study and have at least one of the following diagnoses: shoulder impingement syndrome, rotator cuff rupture, and subacromial bursitis will be included in the study. Individuals with a neurological, orthopedic or cardiovascular chronic disease that cannot be controlled with medication, those who are pregnant or suspected of being pregnant, those with a pacemaker, those with implanted ear hearing aids and those with metallic implants will be excluded.

Individuals' shoulder pain levels, normal joint range of motion and daily living activities will be evaluated before and after treatment.

It is planned to include two separate groups in the study: a conservative treatment group and a group that will receive high induction magnetic field therapy in addition to conservative treatment. Within the scope of conservative treatment, ice application, transcutaneous electrical stimulation-TENS, interferential current, stretching and strengthening exercises, and normal joint range of motion exercises will be applied. Conservative treatment will be continued five days a week for a total of four weeks. High induction magnetic field therapy (Salus Talent, 4 T) will be applied in 10 sessions, 10 minutes, with one day intervals within a four-week treatment program.
