endolite ECVT22L1 Instructions D'utilisation page 3

1 Description and purpose
Application:
These instructions are for use by the Practitioner.
The EchelonVT foot is to be used exclusively as part of a lower limb prosthesis.
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. 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 EchelonVT, 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).
Contra-indications:
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.
Intended for single user.
Ensure that the user has understood all instructions for use, drawing particular attention to the
section regarding Maintenance.

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.
Note:
If in doubt choosing between two categories, choose the higher rate spring set.
Foot Spring set recommendations shown are for transtibial users.
For transfemoral users we suggest selecting a spring set one category lower,
refer to fitting advice Section 7 to ensure satisfactory function and range of movement
