According to the study, 27% of Americans live with a disability that interferes with their activities of daily living, including "serious difficulty hearing," seeing, climbing stairs, concentrating, dressing themselves, and visiting a doctor's office. The respondents answered these questions themselves; here is a PDF of the survey questions.
Of those 27%, 2% say their disability makes it harder or impossible to use the Internet, and 54% of them use the Internet compared to 81% of the adults who did not have difficulties as asked on the survey.
You can view the full report online here. I think it is very interesting information especially when looking at the data from the perspective of advocacy for Internet access for all.
