Abstract

Objective: The aim of this study was to compare the structure of postural sway in healthy people and amputees with SACH foot (solid ankle cushion heel) and single axis foot during standing. Methods: Twenty healthy, 10 amputees with single axis foot, and 10 amputees with SACH foot participated in this study. The structure of postural sway of the subjects was evaluated using approximate entropy (ApEn). Results: People with SACH foot prosthesis exhibit increased regularity in postural sway compared to healthy people and people with single axis foot. Conclusion: Amputees who used single axis prosthesis achieved appropriate adaptation to their prosthesis device. © 2016 Prof. PK Surendran Memorial Education Foundation.
