Description And Intended Purpose; Activity Level - Blatchford EchelonER Instrucciones De Uso

1 Description and Intended Purpose

These instructions are for the practitioner.
The term device is used throughout these instructions for use to refer to
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 allows the
ankle to adjust to a moderate variation in heel heights. 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 the device, 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, users with poor balance, or users
who take part in competitive sports events, as these types of users will be better served by a
specially-designed prosthesis optimized for their needs. Users who require additional support
when standing, e.g. bilaterals, may benefit from an ankle with a reduced range of DF movement–
see Bench Alignment section, or an ankle with a standing mode lock.
Due to the large potential range of ankle movement, it is essential to ensure that the user has
understood all instructions for use, drawing particular attention to the sections regarding safety
and maintenance.
