The manipulation of lymphedema to reduce swelling refers to CDT, created by German doctors, whose frequency of treatment is closely related to the stage in which it is performed and cannot be generalized.CDT is usually divided into two phases.The first phase is decongestive and lasts about 4-6 weeks, using high-frequency manipulation of lymphatic drainage, 1-2 times a day. The second phase is maintenance, which is performed 1-3 times per week or month. CDT follows the path of lymphatic reflux and uses manual manipulative massage for lymphatic drainage to remove edema fluid through the deep lymphatic system and adjacent lymphatic pathways, thus reducing and eliminating edema, which is effective in decreasing the size of the diseased limb and decreasing flare-ups. Manual lymphatic drainage is designed to increase or facilitate the return of lymphatic and interstitial fluids, following the anatomical and physiological pathways of the lymphatic system. Proper use of unarmed lymphatic drainage can increase lymphatic flow up to 20 times greater than normal, and there are few contraindications to manual lymphatic drainage to activate the lymphatic system. The therapeutic effect of manipulative lymphatic drainage is only temporary, especially due to the dysfunction of lymphatic transport as a result of surgical radiation therapy, and it is unlikely to permanently remove the edema fluid from the interstitial tissues. By using manual lymphatic drainage to treat lymphedema, the therapist can effectively change the pathway of lymphatic return and efficiently reduce the edema fluid trapped between tissues. In addition, manual lymphatic drainage reduces tissue fibrosis, decreases skin thickening, and increases immune defenses in the affected area. It is recommended that patients under the guidance of a professional doctor in a regular medical institution or by a doctor for massage therapy, do not massage on your own, so as not to cause adverse effects. At the same time, it is important to pay attention to keep warm and move gently to avoid injury. Each treatment takes about one and a half hours, a course of 20 times, applicable to the limbs of the external genitalia as well as facial lymphedema treatment, the treatment process is non-invasive, safe and comfortable.
