What does VERT measure? The accurate measurement of human performance is important
in evaluating movement. Accurate and calibrated equipment is essential
for the clinician in his/her analysis of the movement. The essentials of movement analysis includes the following
parameters: POSITION Range
of motion, Velocity, and Acceleration are dependent upon accurate
position information. Range of motion is total position change; velocity
is the rate of that change; acceleration is the rate of velocity change.
These are computed values based upon the position information.
FORCE An external influence of pulling or pushing action,
which causes movement to occur. An exercise system must be dynamically
calibrated to provide meaningful information in pounds, kilograms or
newtons. A known force must be applied to the system and its effect upon
the measuring device tabulated. Once a broad range of loads has been
applied on the system and measured dynamically, a force calibration
value is achieved. This calibrated information is stored in the computer
memory to allow calculation of the subject kinetics. WEIGHT
Gravity
exerts a force upon all objects, which results in that object having
weight. Because gravity acts exclusively downward, biological motions on
systems must consider gravitation. Gravity will act against a vertically
upward motion and will aid a vertically downward motion. The
computerized exercise system must account for the gravitational effect.
Only a computerized system with a closed loop system can be calibrated
for gravitational effect.
TORQUE A
force which causes rotation. Mechanically, torque is the product of the
amount of applied force times the perpendicular distance of that force
from the axis about which the object will rotate. Torque then is a
function of both force and distance variables. The calculation of
accurate torque must rely on the computer capability of the exercise
system. Position,
acceleration, and force must be considered in the measurement of dynamic
torque.
VERT can control these parameters in different
modes: Velocity, Fatigue, & Power training.
