Abstract
BACKGROUND: Excessive sweating of the residual limb has a substantial effect on the daily activities of people with lower limb amputation. Prosthetic liners offer protection and comfort to sensitive areas but often exacerbate perspiration. They act as insulators, trapping sweat on the skin’s surface to the detriment of skin health. Recently, liners with perforations have been developed, allowing the moisture to escape. The goal of this study was to assess the impact of such liners. METHODS: A sample group of 13 patients with unilateral transtibial amputation, who wore a perforated liner (PL) as part of their current prescription, was compared to 20 control patients who wore non-perforated liners (NPL). During their routine appointments, they completed a survey of scientifically validated outcome measures relating to their limb health, pain and the impact on daily life over a 12-month period. RESULTS: Patients using the PL had healthier residual limbs, reporting higher scores on questions relating to limb health, experiencing fewer skin issues (pLayman's Abstract Individuals with amputation often find that they sweat more as they exert more energy when walking and because the total surface area of their body is reduced. Silicone liners are used to cushion the residual limb and as a way of attaching a prosthetic leg, but they act as insulators causing the residual limb to get hot and sweaty. The material isn’t breathable, so the sweat is not able to escape, instead staying on the skin’s surface and causing discomfort or leading to the development of skin conditions. Liners that have small holes in them allow sweat to travel away from the body and preserve skin health. Patients who wore a perforated liner, as well as patients who wore a liner without holes, filled in questionnaires about their experience, the results of which were compared. Generally, patients who wore the perforated liner had healthier skin on their residual limbs and experienced fewer skin conditions than the other patient group. Out of the issues they did experience, fewer were attributed to sweating. The study group experienced less frequent pain both in their physical and phantom limbs. They also considered themselves less limited by their prosthetic device and missed fewer days of work. These observations suggest that perforated liners are highly beneficial to patients within the prosthetic field.
