juvenile arthritis
Because contractures from arthritis result mainly from unequal muscle strength, it is
important that the child do all exercises and activities in ways that will strengthen the
weak muscles that straighten the joints, not the muscles that bend them. For example:
139
Do exercises that work this muscle.
YES
This is the muscle
that straightens the
knee and prevents
contracture.
But do not do exercises that work this
muscle.
NO
This is the muscle
that bends the
knee and causes a
contracture.
STRENGTHEN MUSCLES THAT
STRAIGHTEN THE JOINT.
DO NOT STRENGTHEN MUSCLES
THAT BEND THE JOINT.
Follow this same logic with all exercises and activities. And look for ways to make the
exercises useful and fun.
For example, Alicia has arthritis and can no longer walk by herself or straighten her arms
and legs completely. As a way of moving herself about and getting some exercise, she
can sit on a chair with casters, as shown here. But she should be careful to move in a
way that helps prevent contractures.
YES
NO
Pulling herself
forward with her
arms and legs
exercises mostly
the muscles that
bend the joints.
Pushing herself
backward, with her
arms and legs, does
more to strengthen
the muscles that
straighten the
joints.
This can make contractures worse.
This helps prevent contractures.
