I did do the initial reflex exam, but because I knew I'm not qualified I made her aunt, who's a physical therapist, check and came to the same conclusion, then she checked with her doctor who, again, found the same. The only reflex that has not been tested by either a physical therapist or doctor and solely by me was the positive Hoffman's. But I am fairly confident it's there. However, consider that part variable as I could be wrong. The rest is physician-confirmed.
Actually, I was trying to use her as a control when I was self-testing about a month ago and neither of us expected to find anything odd. She's still not very worried about it and I'm trying to encourage her to see a doctor for an MRI, at the very least. Her GP referred her for a head MRI, but she canceled it because she refused to call off work.
Also, no one has said anything about atrophy and I didn't notice any when I looked at her hands and arms. Again, not qualified, but I can make a reasonable estimation. No twitching either, except for her pinky on the opposite hand of the one with weakness.
