A Study Comparing Real and Sham Repetitive Transcranial Magnetic Stimulation in Adults With Fibromyalgia, Assessing Effects on Pain, Fatigue, Sleep, Mood, Quality of Life, Cognition, and Walking Under Usual and Dual-task Conditions

Fibromyalgia is a chronic condition that causes widespread pain and is often accompanied by fatigue, poor sleep, mood symptoms, memory and concentration difficulties, and reduced quality of life. Many adults with fibromyalgia also experience limitations in daily physical functioning. These limitations may include slower or less stable walking, reduced walking endurance, and greater difficulty walking while performing another task at the same time, such as counting or carrying out a mental task. This clinical study is designed to evaluate the effects of repetitive transcranial magnetic stimulation, also called rTMS, in adults with fibromyalgia. rTMS is a non-invasive brain stimulation technique that delivers magnetic pulses through the scalp to influence activity in specific brain areas involved in pain processing, mood regulation, and physical function. The procedure does not require surgery or anesthesia. Participants in this study are randomly assigned to receive either real rTMS or sham rTMS. Sham rTMS is designed to look and feel similar to the real procedure but does not deliver active therapeutic brain stimulation. Comparing real and sham rTMS allows researchers to assess whether any observed improvements are related to the active treatment rather than to expectation or participation in the study. The study evaluates whether real rTMS can improve symptoms and function in adults with fibromyalgia. Outcomes include pain, fatigue, mood, sleep, quality of life, cognition, and walking performance. Walking is assessed during usual walking and during dual-task walking, when participants walk while also performing another task. These assessments are used to better understand how fibromyalgia affects everyday functioning and whether rTMS may help improve both symptoms and objective physical performance. The main hypothesis is that participants who receive real rTMS will show greater improvement than those who receive sham rTMS. It is expected that real rTMS may red
