What is Using both hands

Many everyday activities are carried out with one hand while the other
hand holds the work steady. There are many ways of stabilising objects such
as putting a weight on top or non-slip material underneath. But it is better to
involve the affected hand as much as possible even if only as a rather clumsy
stabiliser. Using the affected hand will help it to recover, will prevent strain
on the shoulder, and swelling or injury to the hand which can occur when it
is left dangling all the time. Using both hands will also promote a more
upright, less one-sided posture.
The affected arm should not be put into a sling because this will
discourage its use and may increase spasticity. The only exception is when
there is a painful dropped shoulder. This should be prevented: it is usually
the result of a helper quite wrongly pulling the patient by the affected upper
arm when giving assistance to get up.
