Thanks, I never knew that was there.
Yes, based on the pictures, I would say your FDI and APB are definitely atrophied. Did they include these muscles in any of your EMGs? Did they show active and chronic denervation? When did you first notice the atrophy and how fast is it progressing? Did neuros ever think it waas carpal tunnel before your ALS diagnosis or did the ALS come first?
I thought my weakness and denervation was all in my lower body, but an EMG last August showed denervation in the FDI and OP (opponens pollicis, which is a little to the outside of the APB). I had never noticed it, but when I was studying my EMGs in December or so, I noticed it and realized I had been favoring my left hand. The pincer grip is failing and sometimes the thumb just sort of gives out. I never trust my left hand with important things... like a glass or bottle of wine. Neither of my muscles is as atrophied as yours, but overall I think I am fairly slowly progressive.
