Testing Photographs

 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.

Right Elbow Flexion is illustrated. 
The attaching strap
is set parallel to the table, so an  @ 90 may be maintained
at the elbow.

Illustrated is the setup for right elbow extension testing. 
By using an electric height adjustable table, to adjust the height to maintain
 @ 90 at the elbow - the time for setup is minimized. 
The patient can complete more
tests during a visit, with a
minimum of fatigue
and discomfort.

Isolating the muscles for testing an elbow extension.  
A consistent method of testing each muscle group is employed, so results are
comparable and repeatable.

By stabilizing the patient,
the tester permits the patient to use only those muscles that are intended to be tested.

The photo shows the muscles  isolated for testing the left ankle dorsiflexion.  

To assist the testing personnel, a remote switch may be utilized so the test may be managed -
started, accepted and continued -  and the muscle or the muscle group tested and
patient  may be stabilized.
