How do you work on the computer at home, and why can't you create a similar environment at work?
If you are disabled from working you do not get unemployment - you must be able to work to qualify for unemployment. Or is it your idea that you're fully able to work in other types of job, such that you would be actively seeking work but not in a desk job?
If you are claiming this to be a work-related condition you can try to qualify for worker's compensation.
