The BTE Dual Inclinometers
The dual inclinometers are used to evaluate spinal range of motion, which allows for sections to be tested
in isolation. You may choose to use a single inclinometer; however, the evaluator must be aware of the
value's origin. For example, if you were to assess lumbosacral flexion by placing a single inclinometer on
the appropriate landmark and have the client flexing from a standing position, the inclinometer will
measure the combined lumbosacral and hip flexion.
The single inclinometer can be used to evaluate range of motion of the extremities. The small goniometer
feature can be used to evaluate the range of motion of the smaller joints in the hand and foot.
The basic premise of the dual inclinometers function is to calculate the amount of rotational displacement
of both the sensors and subtract (or add) the two values to arrive at a true range of motion value.
Components
The dual inclinometers consist of three separate components. First, there are two sensors, referred to as
the Master and Remote sensors. There are also two cords that accompany the BTE Dual Inclinometers.
A Foot Pedal is also available to start and stop measurements using the Inclinometer.
One cord connects the Master and Remote sensors together to allow the calculation of angular
displacements. The ends of this cord connect to the ports at the top of each sensor. The other cord is
permanently attached to the Master sensor at one end and fits into the BTE Data Acquisition Box at the
other end. This cord functions to direct all calculated angles into the ODES diagnostic software system.
The BTE Dual Inclinometers are self-calibrating and never need to be manually calibrated.
The Dual inclinometers are connected to the Data Acquisition Box by a long cord from the Master sensor,
which connects to PORT 12 on the Data Acquisition Box.
When using the BTE Dual Inclinometers to measure range of motion, they must always be positioned in
the same plane and with the hinges facing each other. The following figures demonstrate correct and
incorrect orientation for the Dual Inclinometer placement.
