Better wearing comfort of knee-length elastic compression stockings with an interface pressure of 18–21 mmHg compared to 23–32 mmHg in elderly people after a one day trial – Influence on foot deformities,rheumatism and arthritis

Abstract

BACKGROUND:

Although the efficacy of compression therapy through knee-length compression stockings with an interface pressure of 18–21 mmHg 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 18–21 mmHg (stocking type 1) and 23–32 mmHg (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 (p = 0,045) better wearing comfort. In addition, the Stocking type 2 was significantly too large amongst women in the front foot area (p = 0.044). The most common side effects were constrictions on the proximal lower leg (stocking type 1 = 73,7% (14/19); stocking type 2 = 78,9% (15/19)). Subjects with arthritis (p = 0.006), hallux valgus (p = 0.034) and/or digitus flexus (p = 0.021) 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 18–21 mmHg if the following criteria are met: age ≥65 years, female sex, arthritis, digitus flexus (claw toe) or hallux valgus.
