I like the OPTIMAL scale.
I use it enough to need a spanish translation - you can get a copy of it here (Links or Forms page).
Remember to request copyright permission from the APTA to use it in your clinic.
Like many things, it is not a perfect solution for outpatient physical therapists looking for outcome scales.
The shortcomings of the OPTIMAL are well-described here.
The best critique of the OPTIMAL is that better alternatives exist.
Like a 50-year old dowager waiting for perfect love the quest for 'the one' can leave us frustrated.
Since only 48% of physical therapists currently use outcomes measures it seems like many PTs are waiting for 'the one'. (PHYS THER 2009 89: 125-135)
This spanish version is not 'the one' but it may be a step closer to getting a majority of physical therapists to use outcome measures.
