Moreover, the lower edge of the anti-tipping
support wheels may not be any more than
5 cm from the ground. If a larger gap is
required or necessary, then you need to work
with your therapists and doctors to practice
and learn to handle the increased risk of
tipping.
If the functionality of the anti-tipping
supports should no longer be given or if you
are in any doubt about the serviceability, then
have it checked by your rehabilitation specialist
retailer and have it repaired before any further
use. Otherwise there is an increased risk or
falling of getting injured.
