Forty percent of patients with chronic venous insufficiency (CVI) do not wear their indicated and prescribed compression stockings. Difficulties in donning and a feeling of constraint are the most common reasons for non-adherence.
The aim was to develop a compression stocking system that is easy to don and dose adjustable.
A modular compression stocking kit composed of an understocking and three superimposable leggings (SLLLs) was developed. Substocking pressures (P) at the thinnest part above the ankle (cB level) were 17 mm (understocking) + 15 + 10 + 10 mmHg (3 superimposed leggings; Hatra method). Twenty healthy subjects and 20 patients over 65 years with CVI donned the SLLL compression kit. P was measured in vivo (Picopress method) at the transition of the Achilles tendon to the calf muscle (level cB1) during rest and ankle movements (DSI; dynamic stiffness index) and compared with a strong compression stocking of 40 mmHg (S40).
Twenty (20/20) patients aged over 65 with CVI (C4-6) successfully donned the SLLL compression kit without aid, compared with 12 (12/20) who were able to don the S40 without aid (p = .02). In vivo resting P at level cB1 was 34.3 mmHg (SLLL) compared with 37.3 mmHg (S40) (p = .1). The DSI was 16.1 (SLLL) compared with 17.9 (p = .79; S40; CVI group).
The physical properties of the SLLL compression stocking kit correspond to the characteristics of a strong stocking at rest and exercise (DSI). The donning success rate is excellent (100%). A further potential advantage is that the SLLL leg compression kit is dose adjustable, according to indication or patient tolerance. Wearing comfort over periods of several days and clinical effectiveness need to be investigated in future trials.
40%的慢性静脉功能不全（CVI）患者不穿规定和处方的压缩袜。穿着困难和感到受限是不遵医嘱的最常见原因。
旨在开发一种易于穿着且剂量可调的压缩袜系统。
开发了一种由底层袜和三个可叠加的裤腿（SLLL）组成的模块化压缩袜套件。在脚踝上方最薄处（cB 水平）的底层压力（P）为 17 毫米（底层袜）+15+10+10 毫米汞柱（3 个叠加裤腿；Hatra 方法）。20 名健康受试者和 20 名 65 岁以上 CVI 患者穿着 SLLL 压缩套件。使用 Picopress 方法在跟腱到小腿肌肉的过渡处（cB1 水平）测量体内 P（在休息和踝关节运动期间（DSI；动态硬度指数），并与 40 毫米汞柱的强力压缩袜（S40）进行比较。
20 名（20/20）年龄在 65 岁以上的 CVI（C4-6）患者无需帮助即可成功穿上 SLLL 压缩套件，而 12 名（12/20）患者无需帮助即可穿上 S40（p=0.02）。在 cB1 水平的静息 P 体内为 34.3 毫米汞柱（SLLL），而 37.3 毫米汞柱（S40）（p=0.1）。DSI 为 16.1（SLLL），而 17.9（p=0.79；S40；CVI 组）。
SLLL 压缩袜套件的物理性能与休息和运动时强力袜的特性相对应（DSI）。穿着成功率非常高（100%）。根据适应症或患者耐受性，SLLL 腿部压缩套件还具有剂量可调的潜在优势。在未来的试验中需要进一步研究其数天穿着的舒适度和临床效果。
