Illustrated
is the setup for right knee flexion
testing. A strain
gauge (analog transducer) has
been placed in the path of the exertion
attached to
a non-elastic nylon strap, secured at one end to a
traction
frame, and the other to the patient, via a testing cuff.
Utilizing an electric table (plinth), and an adjuster on the nylon strap,
limb positioning,
joint angle, and force vector for testing a particular
muscle is held constant for every patient. Each muscle contraction
produces a force versus time curve in the form of analog data that is
digitized
and placed in a continuing database.
Peak strength,
area-under-curve, rise time and
co-efficient of effort are all analyzed.
Acquired data may be compiled, queried, and exported to MS Excel for further
analysis.
Patient Progress Report may be utilized to initially evaluate and
longitudinally document the
patient's efforts to an expected "normal"
based on gender, age and BMI. |
