Introduction: Proper fitting of the stump inside the socket and appropriate selection of prosthetic suspension have positive effects on amputees’ satisfaction and could decrease gait deviation, skin problems, and stump atrophy. The suction sockets are commonly prescribed for transtibial amputees to have better suspension compared to the Pin and lock systems. The Seal-In® X5 (suction system) is ...

BACKGROUND The method of attachment of prosthesis to the residual limb (suspension) and socket fitting is a critical issue in the process of providing an amputee with prosthesis. Different suspension methods try to minimize the pistoning movement inside the socket. The Seal-In(®) X5 and Dermo(®) Liner by Ossur are new suspension liners that intend to reduce pistoning between the socket and line...

Individuals with lower limb amputation need a secure suspension system for their prosthetic devices. A new coupling system was developed that is capable of suspending the prosthesis. The system's safety is ensured through an acoustic alarm system. This article explains how the system works and provides an in vivo evaluation of the device with regard to pistoning during walking. The system was d...

introduction: knee orthosis is used in different cases and can be seen pistoning movement in all orthosis. the purpose of this study was to evaluate the effects of increasing mass knee brace and two kinds of silicon and polyethylene (pe) pad on pistoning movement during walking, on health subject. material and methods: a total of 20 healthy volunteers, including 10 men and 10 women, with an ave...

introduction: transtibial amputation is the most common amputation in lower limbs. volume loss of residual limb occurs during daily use of prostheses, which results in pistoning between residual limb and prosthetic socket. the goal of this study was to design and fabricate a pneumatic suspension system in transtibial supracondylar prostheses and to evaluate its effect on residual limb pistoning...

Poor suspension increases slippage of the residual limb inside the socket during ambulation. The main purpose of this article is to evaluate the pistoning at the prosthetic liner-socket interface during gait and assess patients' satisfaction with two different liners. Two prostheses with seal-in and locking liners were fabricated for each of the 10 subjects with transtibial amputation. The Vico...

BACKGROUND Good suspension lessens the pistoning (vertical displacement) of the residual limb inside the prosthetic socket. Several methods are used for measuring the pistoning. STUDY DESIGN Clinical trial. OBJECTIVES To introduce and evaluate a new simple method for measuring the pistoning between the soft liner and socket in transtibial prostheses. METHODS Five transtibial prostheses wi...

OBJECTIVE The objectives of this study were to compare the effects of a newly designed magnetic suspension system with that of two existing suspension methods on pistoning inside the prosthetic socket and to compare satisfaction and perceived problems among transtibial amputees. DESIGN In this prospective study, three lower limb prostheses with three different suspension systems were fabricat...

A simple noncontact device was implemented for measuring the position of the distal residual limb relative to the prosthetic socket during ambulation. The device was a small and lightweight photoelectric sensor positioned within a frame mounted immediately beneath the socket. Calibration tests showed that the sensor had a displacement range of 60.0 mm. The root-mean-square error for all sources...
