Fitting guides

Print the memo sheet (PDF) — one page that captures everything the order form will ask for: patient details, amputation level and activity, control measurements, silicone and suspension choices, thickness needs and the textile design.

• Silicone type: Relax (soft), Active (medium) or Dynamic (harder). For high mechanical stress — high activity, high body weight, short limb — prefer Dynamic. Ask your MotionTech representative for the hardness pad set.
• Control measurements: plan where you will measure, and draw the measurement heights directly on the limb so they are visible in the scan.

Any scanner works if it outputs .stl, .ply or .obj — colour scans preferred, so drawn indications stay visible.

• Position, by preference: standing (soft tissues hang down, limits pistoning) → sitting on a high support → scan of an unrectified plaster positive.
• Three principles: don’t push up the soft tissues; the scanned shape should match the shape at donning; keep the patient comfortable so they stay still.
• BK flexion: scan (and measure) at the flexion angle the liner should have — about 20° pre-flexion recommended, never more than 40°.
• Upload raw: no smoothing, no hole-filling — our designers rework the model under our quality standards, which keeps the satisfaction warranty simple.
• Take videos of the soft tissues moving, and note anything unusual in your own words.

Full detail in the Scan & Order FAQ.

• Order types: new order, copy order (by serial number, with tweaks), follow-up order, warranty claim.
• Thickness: every liner starts from the default profile for the amputation level and silicone; add pads or fill scars and concavities by drawing zones. Limits: 2.5 mm minimum (3 mm for Relax), 25 mm maximum.
• Suspension: distal locking (M10/M6), silicone rings below knee level (rotation control or sleeve-less vacuum) or above knee level (liner–sleeve seal) — combinable.
• Pear-shaped limbs: declare it on the order form’s first page and choose the socket type — compensation is designed in, not drawn as zones. When donning strength is a concern, request a donning & doffing validation before printing.
• Unsure about the model? Ask for a 3D-model validation in the order comments and inspect the design before it prints.

At delivery, walk the patient through donning (see the patient guides) and verify together:

• The alignment line sits as designed («Posterior» back / «Medial» inside) and the thicker zones cover the intended areas.
• No wrinkles or air pockets between limb, liner — and sleeve, if used (horizontal line at joint middle).
• The patient releases vertical tension every ~5 cm while rolling on — especially with compensated liners, where longitudinal stretch displaces the designed thicknesses.
• A few steps in a safe area confirm suspension before the patient leaves.

If a first liner doesn’t fit: document with photos, videos and measurements, and file a warranty claim — the satisfaction warranty covers replacement.

Clinical one-pagers per indication support the coverage conversation with insurers:

• Long & thin residual limb (PDF)
• Pear-shaped residual limb (PDF)

Every indication also has a walkthrough on the use-case pages; reports for the remaining indications are being finalised.
