1 Description and Intended Purpose
These instructions are for the practitioner.
The term device is used throughout these instructions for use to refer to Echelon.
Application
The device is to be used exclusively as part of a lower limb prosthesis.
Intended for a 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. A moderate-energy-return foot with multi-axial
ankle movement. Independent heel and toe springs provides some axial deflection. The split toe
provides good ground compliance.
Activity Level
This device is recommended for users that have the potential to achieve Activity Level 3 who may
benefit from enhanced stability and an increase in confidence on uneven surfaces.
Of course there are exceptions and in our recommendation we want to allow for unique,
individual circumstances. There may also be a number of users in the Activity Levels 2 and 4*
who would benefit from the enhanced stability offered by Echelon, but this decision should be
made with sound and thorough justification.
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.
*Maximum user weight 100 kg and always use one higher spring rate category than shown
in the Spring Set Selection table.
Contraindications
This device may not be suitable for Activity 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
• Increased walking speed
