Isokinetic Testing
What
is isokinetic testing and what does it do?
An
isokinetic devise tests body segments, such as arms, legs
and the spine.
The
specific body part is strapped to a moveable lever arm of a
highly specialized and computerized testing machine.
The
lever arm is programmed to move at a constant speed
throughout the entire range of motion of the given joint no
matter how much muscular force the body part exerts upon the
lever arm.
The
patient/athlete is instructed to give their best muscular
efforts over a series of standardized repetitions.
Common
testing speeds are 60, 90,120 and 240 degrees per second.
Force
curves are tabulated and grafted.
Data
is collated and a computerised report is generated showing
muscle strength, flexibility, and endurance.
A
comparison of the injured and normal arm or leg can be
demonstrated.
Normative
and comparative ratings.
Determination
whether the patient/athlete gave full co-operation and
effort.
It
is recommended the test be repeated, usually in 3 months, to
compare the differences in performance.
