Abstract Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a complex, chronic, multisystem disorder characterized by persistent fatigue, post-exertional malaise, autonomic dysfunction, neuromuscular impairment, and cognitive disturbances. Standard rehabilitation approaches are often poorly tolerated due to symptom exacerbation, highlighting the need for safe, individualized, low-load interventions. Clinical Pilates (CP), emphasizing controlled movement, core stabilization, alignment, and breath work, has emerged as a promising approach for symptom management and functional recovery in chronic multisystem conditions. This case report describes a 46-year-old female patient with ME/CFS and complex post inflammatory syndromes, including fibromyalgia, lymphatic dysfunction, endocrine abnormalities, severe neuropathic pain, and profound functional decline. Prior to illness, she engaged in high levels of physical activity, including walking, running, and recreational sports, but became unable to perform basic daily activities. An individualized, fascia-focused CP program was implemented, emphasizing pain-free fascia stretching, low-load movement patterns, neuromuscular modulation, core stabilization, thoracic expansion, and breath-focused exercises, progressed according to patient tolerance. During the intervention period, the patient demonstrated meaningful improvements in pain, functional capacity, respiratory mechanics, neuromuscular coordination, and performance in daily life. These observations underscore the therapeutic potential of individualized, low-load CP, enabling patients with ME/CFS and complex post-inflammatory syndromes to regain function without triggering symptom exacerbation. This case reinforces CP as a central rehabilitation tool for multisystem chronic fatigue, establishing it as an evidence-based strategy to guide future research and patient follow-up, while encouraging integration of this methodology into patient-centered rehabilitation by both clinicians and certified CP instructors.
