Range of motion. Fillauer has designed the Motion Foot SLX to support each phase of foot function in the gait cycle—from heel strike, to mid-stance, to toe off.
CAUTION: The Motion Foot SLX is designed to be maintenance free and should not be disassembled. The hydraulic unit on the foot is permanently attached to the main and top spring and should not be removed .

NOTICE: Fillauer has tested (ISO 10328) and recommends the use of standard adult endoskeletal components from Fillauer together. Components from other manufacturers may or may not be compatible.
Standard bench alignment techniques may be used for the Motion Foot SLX foot (Figure 2). Before aligning, the initial heel height should be established. The Motion Foot SLX is designed for a 3/8 in. or 1 cm heel height . The initial heel height can be established with a simple spacer under the heel.

Transtibial Bench Alignment The foot should be set in the proper amount of inset found in the evaluation . When using separate suspension and attachment components, the foot may be slightly inset 1 – 12 mm depending on the limb length. Short limb lengths are set with very little inset of 2 – 3 mm and longer limb lengths may tolerate a greater varus thrust at 10 – 12 mm.

Dynamic Alignment The Motion Foot SLX hydraulic Range of motion allows it to conform well to the ground. This characteristic may make the foot appear to be properly aligned after the static alignment. Small adjustments in the alignment however will smooth the transition from heel to toe, optimize gait and efficiency.

“walking down a hill.” Dorsiflex the foot or decrease dorsiflexion resistance to increase the rate of rollover . If a smooth stance phase of gait cannot be achieved, contact Fillauer for additional assistance .
Foot Shell and Spectra Sock (Consumable Components) The Motion Foot SLX uses a unique cosmetic foot shell that is flexible and durable (sold separately). Use care in the installation and removal of the foot shell to maintain its appearance and durability. Always use the shell with an internal Spectra Sock (included).
• If the foot shell is too tight, a smooth-edged shoehorn may be used to disengage the heel lock .

A Fillauer spectra sock and foot shell should be used with this device, the fit of other manufacturers shells cannot be guaranteed .
