I thought they suggest that DOMs does not respond to prednisolone. I envy the people on this post undertaking extensive exercise programs with PMR. It seems they don't experience any DOMs complications with their illness. Small amounts of exercise - especially repetitive - leave me with a high level of pain for more than a week. I walk 20 minutes a day and do 20 minutes of slow stretching exercises, (and that's about the current limit) and still run a small business which involves lots of repetitive steady movements of the small muscles (e.g. soldering). Initiall it took around 3 months after the onset of PMR for me to regain those skills. But none of the work involved can be done for more than 15 minutes at a time - or DOMs will hit for more than a week - and extra pred doesn't help. Sometimes paracetamol can be effective.
