Thanks for the response. I'm not sure which muscle(s); my anatomy knowledge is strictly to the lower extremity; My area of expertise is in formal logic and computer science

My problem is not getting worse, but has changed with respect to the severity of the nerve injury. These muscle problems have existed since a few days after the injury (July 2007) and my first (of six total) surgical procedure to the lower extremity in September 2008, which was an under-diagnosis, significantly worsened my neuropathic symptoms (I didn't know what it was at the time) and my muscular problems got considerably worse.

Since recent decompression surgery, there has been a slight improvement. The severity does seem to coincide with the amount of dorsiflexion/eversion I have. Prior to recent surgery I could barely put my foot on the ground let alone dorsiflex/evert it. Today I can get 0-1cm out from a vertical wall when I do a test with my foot flat on the ground with my knee touching the wall (does that test have a name?).

The comment about a movement pattern problem strikes my intuition as very plausible, but as usual I am compelled to seek out scientific literature to support the hypothesis.

Thanks again for all your input. You have been very helpful.
