5.7 Dynamic Trial Fitting
CAUTION
Adjusting the Settings
Fall due to incorrect or unfamiliar settings
► Only adapt the settings to the patient gradually.
► Explain the effects of the adjustments on the use of the prosthesis to the patient.
INFORMATION
Established initial tension values are used for the settings of the prosthetic knee joint at the fact­
ory.
► If a reduction of the initial tension is required, ensure that the initial tension is always free of
play.
► When initial tension for a setting is reduced to a minimum, ensure constant freedom of play
for the setting (e.g. by establishing a maintenance interval to verify the adjustment values).
This is because the adjustment values can change during use of the prosthesis.
During dynamic trial fitting, the alignment and settings of the prosthesis are checked and adapted
for optimum walking according to the needs and abilities of the patient.
The patient has to learn the safe use of the prosthesis through intensive training.
The following subsections describe the adjustment possibilities for adapting the product to the
patient.
The list below provides an overview of the sequence for working through the subsections:
• Checking the Factory Settings
• Adjusting the EBS
• Adjusting the extension assist
• Adjusting the swing phase friction
• Fine-tuning the settings
