title: A comparison between the suction suspension system and the hypobaric Iceross Seal-In® X5 in transtibial amputees.
abstract: BACKGROUND
  The two passive vacuum suspension systems currently available in total surface-bearing sockets are the hypobaric Iceross Seal-In(®) and the suction suspension system.
  
  
  OBJECTIVE
  The purpose of this study was to compare the effect of the hypobaric Iceross Seal-In(®) liner with that of the suction suspension system for quality of life, pistoning, and prosthesis efficiency in unilateral transtibial amputees.
  
  
  METHODS
  Single-group repeated measures.
  
  
  METHODS
  Ten amputees were enrolled. The pistoning test, used to compare vertical movement of the stump within the socket, and the energy cost of walking test were carried out when the amputees were wearing the suction suspension system and after 2, 5, and 7 weeks of Seal-In® X5 use. The Prosthesis Evaluation Questionnaire and the Houghton Scale Questionnaire of perceived mobility and quality of life with the prosthesis, and the Timed Up&Go Test and the Locomotor Capability Index for functional mobility were also administered at the beginning and end of the study.
  
  
  RESULTS
  The hypobaric Iceross Seal-In® X5 led to significant pistoning reduction and improvement on the Houghton Scale Questionnaire and 3 of 9 domains of the Prosthesis Evaluation Questionnaire. No statistical changes were observed in functional mobility or the energy cost of walking tests.
  
  
  CONCLUSIONS
  Replacing the suction suspension system with the hypobaric Iceross Seal-In® X5 improves quality of life in transtibial amputees.
