1.4 Safety Instructions
INFORMATION
The patient is to be instructed in the proper use/care of the product.
The initial fitting and application of the product must be carried out by trained, qualified person-
nel only. The daily duration of use and period of application are dependent on medical indica-
tion by the physician.
CAUTION
Risk of injury as a result of improper use. The product is designed for use on one patient
only. Parts to be fitted and those parts that come directly into contact with the skin can cause
functional and hygienic risks if the orthosis is used by another person.
An orthosis/support applied too tightly to the body can cause local pressure and, in some cases,
even restrict adjacent vessels or nerves. Do not apply the product too tightly. Consult a physi-
cian immediately if you experience unusual changes (such as increase in pain).
Improper changes to the product are not permitted.
CAUTION
Risk of accident when driving a motor vehicle. The ability to drive a vehicle when wearing a
WalkOn Flex is determined from case-to-case basis. Criteria include the type of fitting (clinical
picture, fitting) and the individual abilities of the WalkOn Flex user.
All users are required to observe the applicable national driving laws when operating motor ve-
hicles. For insurance purposes, drivers should have their driving ability examined and approved
by an authorised test centre.
CAUTION
Risk of injury due to incorrect environmental conditions. The user must be informed of the
risks that exceptional situations might present. For example, jumping down from great height
(more than 1 meter / 39 inches) may expose the spring to severe overload and cause it to break.
