Tissue composition changes and secondary lymphedema
Background: The aim of this study was to determine the impact of dominance and severity on tissue composition changes with lymphedema using dual-energy X-ray absorptiometry (DXA), and to determine the relationships between the DXA-determined tissue volumes and the clinical outcomes determined by perometry and bioimpedance spectroscopy. Methods and Results: Fifty-six women with secondary lymphedema and 44 women without a history of breast cancer or lymphedema underwent measurement of their upper limbs with DXA, perometry, and bioimpedance spectroscopy. Whether the affected side was the dominant or nondominant arm influenced inter-limb tissue volumes differences (F=16.31 to 35.14; all
