Description And Intended Purpose; Contraindications - Blatchford EchelonVT Série Instructions D'utilisation

1 Description and Intended Purpose

These instructions are for use by the practitioner.
The term device is used throughout this document to refer to EchelonVT .
Application
The device is to be used exclusively as part of a lower limb prosthesis.
Intended for single user.
This device provides limited self-alignment of the prosthesis on varied terrain and following
footwear changes. It is intended to improve on postural sway and symmetry while easing
abnormal pressures at the socket interface. The device also includes a spring element capable of
absorbing axial and rotational shocks intended to reduce sheer stresses at the residuum/socket
interface.
Activity Level
This device is recommended for users that have the potential to achieve Activity Level 3 that may
benefit from enhanced stability and an increase in confidence on uneven surfaces. The additional
shock absorption and energy return supplied by the axial spring aims to improve comfort and
performance.
There are exceptions and in our recommendation we want to allow for unique, individual
circumstances. There may also be a number of users of Activity Levels 2 and 4* who would
benefit from the enhanced stability offered by the device, but this decision should be made with
sound and thorough justification.
(*maximum user weight 100kg and always use one higher spring rate category than shown in
the Spring Set Selection table.)
Activity Level 3
Has the ability or potential for ambulation with variable cadence.
Typical of the community ambulator who has the ability to traverse most environmental barriers
and may have vocational, therapeutic, or exercise activity that demands prosthetic utilization
beyond simple locomotion.

Contraindications

This device may not be suitable for level 1 individuals or for competitive sports events, as these
types of users will be better served by a specially designed prosthesis optimized for their needs.
Ensure that the user has understood all instructions for use, drawing particular attention to the section
regarding Maintenance.
Clinical Benefits
• Increased ground clearance reduces risk of trips and falls
• Improved balance through self-alignment
• Improved ground compliance for slope negotiation
• Improved kinetic gait symmetry
• Reduced loading on the residual limb
• Reduced loading rate on the residual limb
• Reduced back pain when twisting
• Increased walking speed
