According to the U.S. Department of Health Human Services, inclusion body myositis, or IBM, is a progressive muscle disorder characterized by muscle inflammation, weakness, and atrophy. The rate of progression varies from person to person, but the disease progresses more rapidly when it begins in older people.
"What will happen, unfortunately, is that it affects the finger flexors," Frampton told CBS News. "That's the first telltale sign is the flexors, you know. So for a guitar player, it's not very good."
Frampton told Rolling Stone some people who have the disease have their swallowing affected, but that has not been the case for him, which means he can continue to sing.
"There's no specific treatment for IBM, Frampton said. "They have traditional medicine that is working. They are coming out with some drug trials. I'm hoping to be involved with those. That is something that is in the future. Right now, the only thing that works for me is exercise. I work out like a maniac all the time. It's strengthening the muscle that I have. It seems to be the best possible thing for IBM is to work out every day."
Frampton has recorded dozens of songs for an upcoming double album, as well as a single album.
“I want to record as much as I can in the shortest space of time,” he said. “I’m very much feeling that I’m playing like always. Some people are saying even better, but I’d let them say that.”
Frampton’s tour starts in July.
