The
innovative pedar® posturography
recording and analysis system
posturography quantifies postural control
in stance in either static or dynamic conditions.
Computerized dynamic posturography (CDP),
also called test of balance (TOB), is a non-invasive,
specialized, new clinical assessment technique
used to quantify the central nervous system´s
adaptive mechanisms (sensory, motor and central)
involved in the control of posture and balance,
both in normal (such as in physical education
and sports training) and abnormal conditions
(particularly in the diagnosis of balance
disorders asdand in physical therapy and aspostural
education). Due to the a complex interactions
among sensory, motor, and also central processes
involved in posture and balance, CDP requires
different protocols in order to differentiate
among the many defects and impairments which
may affect the aspatient's
posture control system.

Regular posturography systems measure the
time course of the Centre of Force (CoF).
The shift of the CoF in the x and y direction
over time is only calculated from the total
force measured under both feet and does not
describe the exact participation of each foot.
By
measuring the pressure distribution underneath
the feet the pedar posturo system allows not
only to measure the force balance between
the left and the right foot but also to determine
which part of the foot is contributing to
the balance.
This is possible because the forces are calculated
from many sensors arranged in a sensor matrix.
Local forces such as those under the forefoot
or toes and the heels can be measured and
it can be analyzed how much they contribute
to the dynamic balance of the body.The pedar
posturo software calculates many parameters
such as CoF/CoP, forces in masks, time processes,
direction of motion, numerical excentri-city,
area of CoF/CoP motion and more.
It is also possible to track the CoP of each
individual foot in bipedal stance mode to
analyze the motor function individually and
compare it with unipedal stance.pedarŽ posturo
hardware.
The pedar®-x posturo system is an accurate
and reliable pressure distribution measuring
system for monitoring local loads and total
forces. The pedar®-x offers the ultimate
versatility with its multiple standard features
and operating modes.
The pedar®-x can be tethered to a PC via
a fiber optic/USB cable. It can also function
in a mobile capacity with its built-in BluetoothTM
technology or, as yet another alternative,
the pedar®-x system’s built-in flash
memory storage allowing data to be collected
anywhere and later downloaded to the computer.
The pedar®-x can be used not only for
posturo-graphy but also for mobile pedography.
The pedar®-x system allows multiple synchronisation
options to use with EMG and video systems.
The pedar®-x can be started and synchronised
by a small wireless remote control.
trubluŽ calibration device
With the aid of the new trublu® calibration
device, all sensors of the pedar® posturo
system are individually calibrated using a
known air pressure.
This procedure is computer-assisted and can
be performed in a short time.
Calibration guarantees accurate and reproducible
data. The calibration curves, one for each
sensor, can be checked by the user at any
time.
This method guarantees the accuracy of the
absolute values measured, not only for the
distri-bution of dynamic body weight, but
also for the local load on each area of the
feet.
All sensor mats come calibrated and calibration
can be tested at any time.
