Background The aim of the study was to assess whether the appropriate pressure profile is generated by thigh‐length graduated compression stockings in human subjects. The effect of leg posture on the pressure profile was assessed in three commonly used brands of graduated compression stockings. Methods The study involved 17 human volunteers from the Department of Orthopaedic Surgery. Three different brands of stockings commonly recommended for the prevention of deep vein thrombosis were applied to each individual and the interface pressure profile under the stocking was measured. The effect of posture was assessed by comparing the interface pressure profile with the subject supine and in standing and sitting positions. Results Appropriate median pressure profiles were achieved only with the subject standing or supine. In the sitting position with the knee flexed, a high median interface pressure in excess of 28 mmHg was generated at the popliteal fossa. Overall, inconsistent performance was found in all three brands of stockings; fewer than 30 per cent of the pressure readings fell within 20 per cent of the ‘ideal’. Reversed pressure profile was observed in over 70 per cent of subjects. Conclusion Thigh‐length graduated compression stockings may be most effective in bedridden patients. Knee‐length stockings may be more suitable for the prevention of deep vein thrombosis in ambulant patients. © 1998 British Journal of Surgery Society Ltd
