Gedetailleerde beschrijving
Lower extremity lymphedema is a chronic condition characterized by impaired lymphatic drainage, limb swelling, pain, reduced physical function, and decreased quality of life. Complex decongestive therapy (CDT) is considered the gold standard treatment; however, additional interventions that may improve physiological and functional outcomes remain under investigation.
Respiratory 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.
Therefore, 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.

Experimenteel: Respiratory and relaxation
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.
Respiratory and relaxation exercises will be performed for approximately 10-20 minutes following each CDT session over 15 treatment sessions.
Participants will also perform a daily home exercise program.
|
Standard Complex Decongestive Therapy consisting of manual lymphatic drainage, compression therapy (bandaging and/or compression garments), skin care education, and therapeutic exercises.
Treatment will be provided in 15 sessions according to the standard clinical protocol.
A structured respiratory and relaxation program performed after each Complex Decongestive Therapy session.
The intervention includes diaphragmatic breathing, thoracic expansion exercises, prolonged expiration breathing, and progressive muscle relaxation or breathing awareness exercises for approximately 10-20 minutes per session.
Participants will also be instructed to perform the exercises at home once or twice daily.
