Clinical Benefits; Activity Level - Blatchford LINX22L1S Manual Del Técnico Ortoprotésico

The enhanced stability system offers:
• Standing Mode, control of knee flexion and ankle for standing
• Controlled ramp descent with Braking effect of knee and ankle
• Enhanced ramp ascent with optimized effect of knee and ankle
• Active control of heel rise during walking
• Dynamic stair descent with an easy start of knee flexion
coupled with increasing support to gently lower the user during flexion
• Supportive resistance to flexion as soon as the knee stops flexing
• Increased supportive resistance to flexion to prevent 'stumbles' associated with instability at
heel strike.

Clinical Benefits

• Increased ground clearance and balance reduces risk of trips and falls
• Improved safety and ground compliance over uneven surfaces and slopes
• Improved kinetic gait symmetry
• Reduced energy expenditure
• Increased walking speed
• Improved adaptation to different walking speeds

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.
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.
Users at Activity Levels 2 and 4 will require softer or stiffer springs as appropriate for the
individual user rather than as shown in the spring selection guide.
*(Maximum user weight 100 kg and always use one higher spring rate category than shown in
the Spring Set Selection table, Section 1.1).
For bilateral transfemoral please contact Blatchford technical support for training and
assessment when descending stairs as this activity carries higher risk of injury.
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.
The device must not be used with large variations in heel height.
