An isokinetic testing machine is disclosed having a support frame, a
sub-assembly disposed on the support frame, a power source operably
disposed within the sub-assembly, a first main arm having a proximal apex
end and a distal end, the first main arm distal end is pivotally attached
to the power source, a first torque arm pivotally and releasably attached
to the first main arm proximal apex end, a user support area disposed on
the support frame proximate to the first torque arm proximal end, a first
load cell disposed within the first torque arm for measuring the torque
when the first torque arm pivots, and wherein the first main arm and the
torque arm can pivot and are configured to a desired position for
isokinetic testing of the knees, the shoulders, and the back of the user.
