Effects of Electrical Stimulation on Lymphedema (A Study from 2015)

The 2015 study investigated the effects of electrical stimulation on swelling and lymphatic drainage in patients with postoperative lymphoedema. Postoperative lymphoedema occurs as a result of lymph node removal or damage to the lymphatic system during surgery and manifests itself as swelling and reduced lymphatic drainage in the affected area.

The study included 36 patients with postoperative lymphoedema of the upper extremity, who were randomly divided into two groups: one group that received electrical stimulation therapy and a control group that received no therapy. The electrical stimulation therapy was applied twice a day for a period of 4 weeks.

The results showed that the use of electrical stimulation led to a significant reduction in swelling and an improvement in lymphatic drainage. Compared with the control group, the electrical stimulation group had a significant reduction in arm volume and a significant improvement in lymphatic drainage. The researchers concluded that electrical stimulation can be an effective therapy option for the treatment of postoperative lymphoedema.

It was assumed that electrical stimulation promotes lymphatic drainage by activating the smooth muscle cells in the lymphatic vessels and by stimulating the muscle pump. Electrical stimulation triggers muscle contractions that improve blood and lymph flow in the affected area and can thus reduce swelling.

It is important that electrical stimulation is carried out by a qualified professional in order to minimise possible risks and side effects.
