thats dificult to tell.
the best it is to send all your certificates, translated and certified to the ISCP when you apply. Being from the European union they normally send you 6 weeks of training in a irish hospital in cardiorespiratory care, 6 weeks in neurology and other 6 in muskuloskeletal (nowadays you can do also an exam in every part). By my own experience they only took into account my course transcript and my work experience in Ireland, not the one abroad. But I think you have a very good cv, a lot of academic certificates and participation in researchs!
As they say in their website, getting recognition is that your level is the same than an irish graduate. So i dont think you should do any course refresher (unless is in Ireland...). honestly I think that the job situation is so bad at the moment that they make it a bit difficult for foreigners. I've heard of a senior physio in the public sector who applied for ISCP membership and He was told to do a period of adaptation in the area in which He wasnt a senior, after 10 years working in Ireland!
Did you have a look to the application form yet? Do it to have an idea at what they are asking for.
My advice is just send all documents and wish for the best. if you can do any work placement or refresher course in Ireland do it, as they value more the irish standards (this is only my own experience).
Also, if you have more than 3 years exp, your chances to find a job in private practice are good. the public sector is nearly impossible, there are 2 panels of physiotherapists waiting for vacancies and the panel closed in December 09.
Good luck Angrybeaver, and patient with the paperwork!!!
