Background: The success in multi-layer bandaging (MLB) relies on the technique of the therapists. The purpose of this study was to elucidate the compression pressure of MLB by lymphedema therapists.
Methods: We investigated the pressure of MLB applied by 48 lymphedema therapists. The average age was 43.5 (range 23-66) years old. Seventeen (35.4%) of the therapists had the clinical experience of MLB. We prepared ordinary compression materials and asked them to apply MLB to the whole lower limb of healthy volunteers, presuming moderate lymphedema. We attached the probe of Picopress at the Achilles tendon-muscle junction and measured the pressure three times: phase 1, resting condition; phase 2, after ankle exercise; and phase 3, after knee bend.
Results: The average pressure in phases 1-3 was 51.9, 48.9, and 45.5 mmHg, respectively. Only 13 (27.1%) of the therapists achieved 50-59 mmHg which is suitable for lymphedema treatment and the pressure varied by the training courses. The pressure decreased as the blank period got longer after finishing training courses (R = - 0.39).
Conclusions: The pressure of MLB varied in different therapists and different training courses. This fact indicated the necessity of uniform curriculum in training courses including measurement of the bandaging pressure.
