Abstract

Physiotherapy of lymphedema requires knowledge of: a) how high external pressures should be applied manually or set in compression devices in order generate tissue pressures high enough to move the fluid to the non-swollen regions and b) how to measure the tissue fluid flow. We measured tissue fluid pressure and flow under the skin in the subcutaneous tissue of lymphedematous limbs stage II to IV at rest and during manual and pneumatic compression under various pressures and sleeve inflation timing. In obstructive lymphedema of lower limbs tissue fluid pressures in the subcutaneous tissue was 2.5±3.0 mmHg (range-1 to +10 mmHg) and did not differ from those measured in normal subjects. During manual massage the applied force generated pressures ranging from 60 to 120 mmHg. Pneumatic compression generated tissue fluid pressures depending on sleeve inflation pressures, however, they were on the average 20% lower than in the inflated chambers. The high pressure gradient across skin and subcutis could be explained by skin rigidity (fibrosis), low hydraulic conductivity of subcutis and dissipation of the applied force in subcutis to the proximal non-compressed regions. Strain gauge put around the limb provided data on girth changes during compression and allowed to calculate the approximate volume of the proximally displaced fluid. It showed that tissue fluid flow occurred during manual compression only during pressing of tissues to stop immediately after its cessation. In contrast, pneumatic sequential compression produced unidirectional flow toward groin without backflow. The total proximally displaced volume from ankle to groin was up to 100ml/cycle. The obtained data should be useful for physiotherapy allowing to set the manual or pneumatic compression parameters at levels corresponding to the physiological conditions.
