Airplane travel and lymphedema: a case study.

A single subject prospective study of the relationship between air travel and lymphedema is reported. This proof of concept study was aimed at assessing the feasibility of using self-measured, inter-limb impedance ratios as a quantitative measure of lymphedema immediately prior to and following flying. The participant, a breast cancer survivor with lymphedema, measured whole arm impedance prior...
