Intended Use - Otto Bock 1E57 Lo Rider Instructions For Use Manual

1.1 Construction and Function
The 1E57 Lo Rider prosthetic foot is suitable for walking on various surfaces
and for a wide range of speeds.
The special combination of carbon and polyurethane absorbs heel strike.
The prosthetic foot permits perceptible plantar flexion at heel strike and a
natural rollover movement. Stored energy is released by the spring ele­
ments.
1.2 Combination possibilities
This prosthetic component is compatible with Ottobock's system of modular
connectors. Functionality with components of other manufacturers that have
compatible modular connectors has not been tested.
Limited combination options for Ottobock components
• High ankle moments occur on the prosthetic foot. Only use structural
components below the knee joint/prosthetic knee joint which are
approved for a higher body weight. (Example: body weight = 90 kg,
structural components approved up to 125 kg)
