Here are some key quotes from today's show:

You may have the range of motion, but are you actually able to use it?
You haven't truly injured yourself, you've just lost your ability to compensate.

And we discuss a case study today, where the following paragraph is germane.

"Abnormal gait changes might be the first signs of an early slow cooking neurologic disorder. Most, not all, pathology is afferent, yet most (not all) EMG/NCV testing is geared towards the efferent pathology (motor end organ disease, not sensory compromise), hence, testing can miss your client's pathology.  We discuss a classic case where the client clearly had the beginnings of a neurologic disorder on our exam (clonus and joint position sense changes and clear ataxic gait) yet the testing "that was done" showed a normal study of this client.  Much pathology is afferent, the input is the problem, so you need to consider requesting Sensory nerve action potentials, SSEP and F-wave testing, because they are difficult to elicit and good technique is paramount. Hence these extra components of the test are not done, and you need to ask for this in your testing.  "Maybe it's not there because you are not looking".  We have much more on this topic, come listen to Podcast 138 and get the full monty."
