Effectiveness of manual lymphatic drainage and intermittent pneumatic compression in lymphedema maintenance therapy.

Abstract

Background: To compare the effectiveness of intermittent pneumatic compression (IPC) and/or manual lymphatic drainage (MLD) associated to compression stockings in the maintenance treatment of lymphedema. Patients and methods: Patients in the maintenance phase of lymphedema therapy with MLD and compression since more than a year with stable values for weight and circumferences of ankle and calf were asked to participate in a study: Compression had to be worn daily, (1) 4 weeks IPC+MLD, (2) 4 weeks MLD alone, (3) 4 Weeks IPC alone (Order 1 and 3 was randomized). At the beginning and after each 4 weeks, circumference measurements (by hand and by machine: BT600^®, Bauerfeind) were documented, pain and discomfort were assessed, and quality-of-life questionnaires were completed. Results: Of 20 participants, 18 (14 female, 4 male), mean age 59.6 years (48-89) could be evaluated. 11 subjects had bilateral, 7 unilateral, 5 primary, 13 secondary lymphedema since 2-20 years (mean 7.7), the subjects had received MLD and compression for 2-14 years (mean 6.4), 1-3 times per week (mean 1.5). The BMI ranged between 21 and 47 (mean 33.7). No differences between any phases were found for: Calf and thigh volume, circumference of calf. Only the ankle circumference was significant less (-0.22 cm) when using "both" (IPC+MLD). Compared to before the study, quality of life was better in all three phases, but with a significantly higher improvement in the phases with IPC than in the phases without. Conclusions: There were no differences in objective measurement between MLD alone, IPC alone or both, excepting the minimal significant difference in ankle circumference after IPC+MLD. QOL favored IPC application. Considering the economic consequences of these results, a change of maintenance therapy with MLD weekly over years in favor of permanent care with IPC and few appointments of MLD per year should be considered and further investigated.
