მნიშვნელოვანი შეტყობინება: This information is provided for educational purposes only and does not constitute medical advice. Peripheral arterial disease rehabilitation and exercise programs should be implemented under appropriate medical supervision. Before beginning any exercise program, individuals with peripheral arterial disease should undergo proper medical evaluation and clearance. Exercise prescription should be individualized based on disease severity, comorbidities, functional status, and personal goals. While exercise therapy is generally safe for stable peripheral arterial disease, certain high-risk conditions may require special precautions or modifications. This article is not a substitute for professional medical advice, diagnosis, or treatment. If you have been diagnosed with peripheral arterial disease or are experiencing symptoms such as leg pain with walking, please consult with a healthcare professional for proper evaluation and treatment recommendations.

დასკვნა

Exercise rehabilitation represents a cornerstone therapy for peripheral arterial disease, offering substantial benefits for walking capacity, quality of life, and cardiovascular health with minimal risks. The physiological adaptations induced by regular exercise extend beyond simple hemodynamic improvements to include metabolic efficiency, skeletal muscle remodeling, and systemic cardiovascular benefits. While supervised exercise therapy remains the gold standard approach, home-based programs and technology-assisted interventions are expanding accessibility and addressing implementation barriers. Despite strong evidence supporting its efficacy, exercise rehabilitation remains underutilized in clinical practice, highlighting the need for enhanced awareness, improved referral pathways, and innovative delivery models. As research continues to refine optimal protocols and implementation strategies, exercise therapy should be considered an essential component of comprehensive care for patients with peripheral arterial disease.
