Determine the posturographic characteristics of eccentric, isometric and concentric
movements in healthy subjects as well as in subjects with chronic, orthopedic conditions /
pain not involving the lower extremities. The squatting movement (going down from a stand up
position, bending the ankle, knee and hip joints, and then returning to the stand up
position, while not lifting the feet from the supporting ground surface) is a simple motion
that involves all three types of movements: eccentric (the going down), isometric (holding
the down position for a couple of seconds) and concentric (the coming up). It is
hypothesized that non-healthy subjects will not have "smooth" movements, and posturography
could be used to separate between healthy and non-healthy subjects.

Subjects will undergo Computerized Dynamic Posturography (CDP) testing using the modified
Clinical Testing of Sensory Integration in Balance (mCTSIB) protocol: the subjects will be
required to stand on a hard or compliant surface (a 4" tall foam cushion of known mechanical
properties) in a comfortable posture, feet shoulder width, with eyes open or closed, head
straight and arms to the side and free to move, gazing forward, and breathing normally.
Subsequently, subjects will be asked to stand first on the right leg and then on the left
leg, raising the other leg (flexing the hip about 45 degrees), bending (flexing) the knee 90
degrees, keeping the arms extended and moving them laterally (abduct shoulders to 45 degrees
and extend both elbows) to help maintaining balance with eyes open. Finally, subjects will
be asked to perform 10 repetition of the squatting movement, with the operator pacing them
(telling them when to start and when to stop the movements). The results of the mCTSIB,
combined with an initial physical and neurological examination will be used to classify the
subjects into the healthy and non healthy group.
