For LEFT HIP angle feedback
Position this sensor over the lateral side of the
hip joint and place the stay with the white line
along the trunk as shown in
Figure 8
Ensure the stay marked LEFT
THIGH is on the left thigh
•
For RIGHT HIP angle feedback
Position this sensor over the lateral side of the
hip joint and place the stay with the white line
on thigh.
Ensure the stay marked RIGHT
THIGH is on the right thigh
Hip Joint Angle Feedback
The Angle Sensor can be placed over the
elbow joint
as shown below in

Once the angle sensor has been positioned on the
client, insert angle sensor plug into the input socket
as shown in Figure 10.
Turn on
control unit using the side toggle switch. One
of the green or red LEDs will come on
.
Set volume
by using the volume control dial(
5
)in a
clockwise direction so the speaker can be heard or
alternatively plug the headphone into socket (
4
) and
adjust volume until it is comfortable for the client.
Set Target Range
Position sensor at angle where feedback is
required.
The therapist needs to set the correct upper and lower
limits. Make sure the two dials are in the following
default positions:
•
Lower limit
dial (
10
) fully anti-clockwise
(minimum position)
•
Upper limit
dial (
2
) fully clockwise (maximum
position)
Firstly, establish lower limit. So, turn this dial (
10
)
clockwise until you hear a sound from the speaker /
headphone.
Now establish upper limit by turning this dial (
2
)
anticlockwise, until you hear a sound from the speaker.
In summary, when the
client’s
joint angle is between
the lower and upper limit values, the client will hear no
sound. If the joint angle is outside these two limits,
then the client will receive feedback.
The sound changes and increases in pitch the further
away the client gets from the target range.
Before using the headphones turn the volume
control back to minimum then slowly increase
until the sound is comfortable for the client
.
