Assessing the Physical and Clinical Characteristics of a New Adjustable Compression Wrap: Insights from a Single-center Pilot Study in India

Abstract

Introduction: Adjustable wraps are a revolutionary avenue in compression therapy because of their ease of application and removal, as well as their ability to be manipulated and readjusted, particularly in older adult patients with leg ulcers. Methods: We analyzed the physical and clinical features of a new adjustable wrap marketed by Vein Care, India. Hirai leg was used to demonstrate the stiffness of the wrap, followed by validation on five healthy male participants. Next, we conducted a pilot clinical study to assess the effect of wearing the wrap for 4 h on volume reduction in seven patients with open leg venous ulcers. Results: The Vein Care Calf Compression Wrap® functioned similarly to a short stretch bandage, which we demonstrated through the tests performed on Hirai’s leg and on healthy participants. In the pilot clinical study, following 4 h of application, a statistically significant decrease in total leg volume (median 34.5 cc; P = 0.018) was observed. Moreover, a significant decrease in volume at the calf level compared to the lower leg (P = 0.038) was noticed. However, no significant correlations were found in volumetric reduction with age or body mass index. The wrap posed challenges in applying pressure exceeding 40 mmHg due to its unique composition, stretch, and stiffness properties. This characteristic is especially significant for patients with diabetic or mixed arteriovenous ulcers (ankle–brachial index >0.5 and <0.8). Conclusions: The wrap’s clinical utility and effectiveness necessitate additional clinical trials and studies with a greater number of patients from diverse demographics.
