Researchers, including those at MU, have found that the most effective method of care for lymphedema is complete decongestive physiotherapy, in which therapists use specialized lymphatic massage techniques to reduce protein-rich fluid buildup. Bandages and compression garments also help to reduce swelling.
One of Armer's innovations at MU is measuring patients' arms with a perometer, a machine that was first used to fit garments for swollen limbs. First implemented in a research setting at MU, the machine has a large optoelectric frame that glides over a patient's arm, scans its image and records an estimated limb volume reading. Perometer measurement is as, or more, accurate than several previous methods to measure arm circumference and volume. The machine is now used in about 20 sites across the country.
Highlights of MU Sinclair School of Nursing research from the past 10 years reveal that there is a 40 percent higher risk of developing lymphedema in women with a body mass index (BMI) classified as overweight or obese compared to normal-weight women. The researchers also found that younger patients may have less occurrence of the condition but tend to report more symptoms, which could be a result of psychological and aging-related factors.
"In addition to our previous findings, we're currently studying whether there are any genetic factors that increase the risk of lymphedema," Armer said. "A pilot study now underway and a proposed multi-site research study will look at the possibility of genetic predisposition for secondary lymphedema. The results could be applied to cancer treatment in which surgery and radiation affect the lymphatic system."
The American Lymphedema Framework Project collaborators aim to document a standard of care reflecting best practices that will provide a clear, national consensus for how to diagnose lymphedema and when to start treating it.
