Introduction
We aim to analyze the correlation between inter-limb ratio (ILR) of circumference, volume and bioelectrical impedance in lymphedema patients and to reveal the usability of bioelectrical impedance analysis (BIA) in the evaluation of lymphedema, especially as an outcome measure of treatment.
Method
This is a prospective study of 54 patients with cancer treatment related lymphedema (CTRL) who were admitted to a secondary university hospital for a short-term treatment.
Among them, only patients who had agreed to participate in the study and have completed the complex decongestive therapy were included. Lymphedema was evaluated with BIA and circumference measure at admission and before discharge. The volume of limb was calculated from circumference measures using the formula for a truncated cone. The ILRs of circumference, volume and bioimpedance on the affected and unaffected limb were calculated. The initial and follow-up results of circumference, volume, bioimpedance and ILRs for each parameter were compared. The correlations between initial and follow-up ILRs, and changes of each ILR were analyzed.
Result
Total 29 CTRL patients were included in this analysis. Follow-up results of circumference, volume, bioimpedance and ILRs of each parameter showed significant improvement (Table 1, p<0.05).
The absolute values and change of ILR were the highest using BIA. Initial and follow-up ILRs of each parameter showed significant correlations (Table 2).
Conclusions
As initial and follow-up ILRs of bioimpedance correlates with respective circumference and volume, and the absolute values and change of ILR was the highest in bioimpedance results, BIA can be used as a useful tool for outcome measure of lymphedema treatment. |
