6.1 Shoe Selection
CAUTION
Incorrect effective heel height
Falling injuries due to loss of functionality
►
When buying new shoes, be sure to observe the predetermined effective heel height.
Effective Heel Height
The effective heel height of the prosthesis is determined during the construction of the prosthesis.
The heel height of the prosthesis cannot be altered and is calculated by the heel height minus the
forefoot height.
Calculation of the effective heel height:
The effective heel height (a - b) of your pros­
thesis is:
……..
Do not use your prosthesis without a shoe that correctly balances the heel height of the prosthetic
foot. Otherwise, extension loading of your knee joint and a risk of slipping may result.
6.2 Check
CAUTION
Use of a worn or damaged prosthesis
Restricted support or injuries due to changes in or loss of functionality
► Before each use, check the prosthesis for functional reliability and for possible wear or dam­
age.
►
If the prosthesis or a component of the prosthesis shows any signs of wear (e.g. tears,
deformations, poor fit) or damage, the prosthesis should no longer be used.
CAUTION
Volume fluctuations of the affected limb or problems with the fit (e.g. caused by growth)
Injuries, friction, pressure sores, circulatory disorders and paralytic symptoms caused by prob­
lems with the fit
►
If the product is fitted during the growing phase, it must be adjusted according to changing
body dimensions.
►
Check the skin daily for damage and sensitivity disturbances (visually and by palpitating).
►
Please consult your doctor or prosthetist in case of any signs of skin damage, even if they
are only minor.
Please verify that your prosthesis is undamaged and functional prior to each use.
Every time you put on your prosthesis, verify that the prosthesis is firmly in place by pulling on it.
First-time users in particular have to learn how to handle the prosthesis. Donning and doffing, sit­
ting, standing, and walking, as well as possible falling must be practised. Your doctor, physio­
therapist or prosthetist can provide you with additional advice on prosthesis training.
Special attention was paid to the materials used for your prosthesis. They were tested for skin tol­
erance. If skin changes develop on your residual limb, please consult your doctor in a timely man­
ner.
