2. INCLINOMETER
An inclinometer is a device used to measure angles.It
is commonly used in physiotherapy to measure the
range of motion (ROM) of joints and very similar to a
goniometer.
The ROM is the amount of movement that a joint can
make.
How an inclinometer works
An inclinometer has a housing that contains a sensor.
The sensor is sensitive to gravity and measures the
angle of the housing. The angle is then displayed on a
digital display or a dial.
3. • An inclinometer is used to measure the ROM of joints in a variety of
ways. One way is to place the inclinometer on the joint and then move
the joint through its range of motion.
• The angle of the inclinometer will change as the joint moves. The
maximum angle reached is the ROM of the joint.
• Another way to use an inclinometer is to measure the angle between
two body parts. For example, a physiotherapist might use an
inclinometer to measure the angle between the thigh and the shinbone.
• This measurement can be used to assess the alignment of the knee
joint.
4. ADVANTAGES
There are several advantages to using an inclinometer in physiotherapy.
• One advantage is that it is a relatively inexpensive device.
• Another advantage is that it is easy to use.
• The inclinometer can be used by physiotherapists and patients alike.
5. DISADVANTAGES
There are a few disadvantages to using an inclinometer.
• One disadvantage is that it can be difficult to measure the ROM of
small joints.
• Another disadvantage is that the inclinometer can be affected by
vibrations.
6. For Lumbar Flexion and Extension
• Using a single mechanical inclinometer, place the middle of the base at
T12. Have the patient flex forward keeping the knees straight and at the
end-point, bobb up and down several times to remove the slack, then take
the measurement.
• Repeat 2-3x to make sure the inclinometer did not move & some other
error did not occur. Place your finger/thumb nail on the dial where the
pendulum stops, remove the inclinometer from the patient and have the
patient stand up. Read the long lines (10’s), calculate the ROM, and record
the number in the “Flexion” column / T12 row.
• Replace the inclinometer at T12 and repeat this process in extension and
record the measurement under the “Extension” column in the T12 row.
7. • Repeat the flexion and extension measurements at S1 (upper gluteal
fold) and place in the S1 row. Subtract the S1 from the T12 number
and place the difference in the “True Lumbar FL / EXT” cell, below
the 2 numbers. Record the “true lumbar flexion & extension” on the 2
page, Exercise screen exam form and on the 1 page “Exercise Screen
Results” form.
• Use 2 inclinometers for all other spinal ROM’s (the “normative data”
are in parentheses)
9. Cervical spine
Inclinometer alignment
• Palpate following bony landmarks, and align inclinometers
accordingly. Ensure that inclinometers are set at 0 degrees once they
are positioned on patient.
Patient position
• Sitting erect
After being instructed in motion desired, patient actively flexes cervical
spine. Patient then returns to starting position. This movement provides
an estimate of ROM and demonstrates to patient exact motion desired
