6.3.2 Information about the
"Find angle, passive"
coordination protocols
This is the symbol for the "Find angle, passive"
protocol:
The "Find angle" protocol is based on the so-
called angle reproduction test.
With this protocol, the patient is prompted to
press the OK button when the knee reaches a
number of preset angles. The current carriage
position is not indicated on the display in this
case. This exercise is meant to improve the pa-
tient's capabilities to perceive the current knee
joint angle.
This is a passive operating mode.
In all cycles between extension and flexion, the
patient is prompted to indicated the angle. If the
patient believes that the knee angle has been
attained, he is prompted to confirm this with the
OK button. The angle to find is indicated until
the OK button is pressed.
When OK is pressed, the carriage displays the
angle attained and assesses the result in relation
to the angle wanted.
If the deviation is within the tolerance of 10°, the
attempt was successful and a positive feedback
icon is displayed:
If the deviation is outside the tolerance of 10°,
the attempt failed and a negative feedback icon
is displayed:
The number of successful and failed attempts is
permanently displayed for reference.
At the end of the session, the patient can assess
his success and compare it with the previous
session.
If the carriage is stopped with OK, the requested
angle as well as the actual angle are is displayed.
Patient treatment can be resumed by pressing
the OK button. Subsequently, the patient will be
prompted for the next angle.
The carriage indicates the following angles
which must be identified in this order.
30°
15°
60°
45°
0°
90°
The patient will only be prompted for angles
from the current range of motion set at the
carriage. After all possible angle settings have
been displayed, the cycle starts over with the
first angle.
Example:
The currently set range of motion is: 0° / 10° / 60°
The patient is prompted for the following angles
in this order:
30°
15°
45°
