RESUMO
BACKGROUND: Although the efficacy of compression therapy through knee-length compression stockings with an interface pressure of 18-21âmmHg for leg oedemas has been confirmed by many studies, 91% of patients are still treated with a higher interface pressure. METHOD: In this prospective open randomised monocentric study 19 patients (age ≥65, movement restrictions and symptomatic leg oedema) received knee-length compression stockings with an interface pressure of 18-21âmmHg (stocking type 1) and 23-32âmmHg (stocking type 2). On two consecutive days each of the two compression stocking types were worn for at least 8 hours. After this test period, both stocking types were assessed subjectively and skin changes were recorded. RESULT: A significantly (p-value <0.001) subjective improvement of the symptoms and complaints based on leg oedema was reported with the knee-length compression stockings. The Stocking type 1 recorded a significantly (pâ=â0,045) better wearing comfort. In addition, the Stocking type 2 was significantly too large amongst women in the front foot area (pâ=â0.044). The most common side effects were constrictions on the proximal lower leg (stocking type 1â=â73,7% (14/19); stocking type 2â=â78,9% (15/19)). Subjects with arthritis (pâ=â0.006), hallux valgus (pâ=â0.034) and/or digitus flexus (pâ=â0.021) found the socking type 1 significantly more comfortable. CONCLUSION: In order to achieve optimal patient compliance it is recommended to prescribe knee-length compression stockings with an interface pressure of 18-21âmmHg if the following criteria are met: age ≥65 years, female sex, arthritis, digitus flexus (claw toe) or hallux valgus.
