Effect of prosthetic socks on the frictional properties of residual limb skin

► In vivo friction of residual limb skin against prosthetic socks is investigated. ► Wool and nylon socks have HYPERLINK “javascript:;” coarse weave surfaces and hard protruding textile fibers. ► Wool and nylon socks cause clear microscopic friction trauma to the skin. ► Cotton and silk socks have soft and smooth surface textile features. ► Less friction irritations are observed when skin slid against cotton and silk socks.
