Abstract

Background and aim: It is unclear how total sock ply and thickness are related when more than one sock is worn. The objectives were to determine whether the thickness of one multi-ply amputee sock of ply P was the same as the thickness of a stack of reduced-ply socks of total ply P, and whether the thickness of N single socks stacked one on top of the other was equal to the sum (1 to N ) of the single sock thicknesses. Technique: Using a custom instrument, compressive stresses were applied while sock thickness was measured. Discussion: The thickness of one multi-ply sock of ply P was typically less than the thickness of a stack of reduced-ply socks of total ply P . The thickness of N single socks stacked one on top of the other was approximately equal to the sum (1 to N ) of the single sock thicknesses. Clinical relevance: Our findings suggest three 1-ply socks to be 20% greater in thickness than one 3-ply sock, and one 3-ply + two 1-ply socks to be 30% greater in thickness than one 5-ply sock.
