There are a host of things that they can use to test. one being EMG study, muscle biopsy, genetic testing or just plain physical examination. I was diagnosed by physical examination( coupled with the idea that they think my 6 yr old has it).
i have a long face and hollowed temples which they say is do to muscle wasting. I also have what is called grip myotonia, where if i grip something tightly say a cup or something, a lot of the time my grip doesnt want to let go and will take longer to relax. There are some good youtube videos demonstrating it.
