Complex decongestive therapy (CDT) is considered the gold standard treatment; however, additional interventions that may improve physiological and functional outcomes remain under investigation.\n\nRespiratory exercises may facilitate lymphatic return through changes in intrathoracic pressure, whereas relaxation training may reduce sympathetic activation and improve exercise tolerance. Despite these theoretical benefits, there is limited evidence regarding their combined effect on muscle oxygenation in patients with lower extremity lymphedema.\n\nTherefore, this randomized controlled study will evaluate whether adding respiratory and relaxation training to CDT improves muscle oxygenation measured by wearable near-infrared spectroscopy (MOXY), functional capacity assessed with the Six-Minute Walk Test, and limb volume compared with CDT alone.",[32,39],{"label":33,"type":34,"description":35,"interventionNames":36},"Respiratory and relaxation","EXPERIMENTAL","Participants in this group will receive standard Complex Decongestive Therapy (CDT), including manual lymphatic drainage, compression therapy, skin care, and therapeutic exercises, together with respiratory and relaxation training.
