@ray666 Hi, Ray,
You have me in the research mode here (which is a good place to be when there doesn't seem to be a lot of outside help). Putting the specific muscle fibers measured into quotes from my diagnosis: ""Right peronesis longus muscles" and "Left peronesis longus muscles", these indicate long-fiber (elongated shape rather than large) according to verywellhealth.com, one of several websites which offered an explanation of the distinction between long and large fibers. Here's the real kicker: according to this and other websites, these longus muscles are responsible for the "crucial role in foot movement and stability" and state that (in layman's terms) dysfunction of these long-fiber muscles lead to balance and gait problems. Hmm...movement, stability, balance, gait...ring any bells?
As to the Carpel Tunnel, that diagnosis was made by separate EMG testing, and the Occupational Therapy I received was incredible. I am confident that I will never even have to make the decision to have surgery if I just continue with the tools and instruction I was offered. In any case, I just couldn't, living alone and hoping/planning to stay that way.
Let the research continue. Peace, Ray~
