Prof Miro Denislic, a neurologist from Solvenia, presented their findings which, in keeping with several other papers, showed that improvements in fatigue were the most persistent benefits in patients after angioplasty. I (Dr Tom Gilhooly) presented our early findings from structured telephone questionnaires on 45 patients at one month post procedure. This shows 60% of patients reporting an improvement in quality of life and a similar percentage reporting an improvement in fatigue.
Another Polish paper showed no change in the EDSS score at 6 months but an improvement in fatigue. The EDSS ( Expanded Disability Status Score) relies very heavily on measuring motor function and does not appear to be sensitive enough to pick up improvements in many other areas such as sensation, bladder function and fatigue. It is doubtful if this tool will be useful in future studies as there are other validated research tools which are more sensitive.

Which other validated research tools might those be? With the EDSS, with it relying heavily on motor function, it does seem that motor function is not something that is as reliably improved post-procedure.
