Otto Bock 480-520 Patient Instructions For Use

Objective
: To allow technicians a quick reference sheet for CPM set-up instructions
to increase accuracy and improve patient care.
Step Action
1. Identify the proper placement of CPM location. It should be in the same
location that the patient would be using in their home. Discourage patients
from moving the CPM from one room to another, for this may cause the
alignment of the fitting to get moved.
2. Apply all of the padding to the machine as directed by manufacture.
3. Place the CPM next to the patient to estimate the length. It is better to
over-estimate the length and shorten it for the patient. Keep the foot
portion of the CPM loose to allow for movement when the patient gets
into the CPM.
4. Set the CPM to 40 – 45 degrees.
5. Place the patient's leg into the machine and begin your adjustments
working down the leg fitting the foot last.
6. The knee should be aligned with the hinge of the machine fitting directly
with the knee. To check this step, use the machine to bend the knee.
Next fit the lower leg and then finally the foot. The foot plate should not
be pressed against the foot and the foot should be in a comfortable
postion.
7. The patient should be educated on knee placement and how it should be
checked each time they enter the CPM. They also need to be instructed
that the thigh strap and foot strap should be placed tightly around the leg.
8. Safety Education: The patient should have no sharp pain with the use of
the CPM. There may be a pull at the knee and that is normal. If they
increase the degree there will be higher initial pain when reaching the
higher range. There should be no bruising of the hip or calf, if this occurs
the padding is not tight enough or the machine is not in proper alignment.
9. CPM should be used under the direction of a physician or therapist. Any
questions about setting or duration should be directed to the treating
doctor or therapist.
