Now, that you mentioned. I believe so, also. I'll modify.
But, as a personal curiosity, I suppose that "modality" has another sense (it popped in my mind because of the Romanian word, but I start to believe is a kind of "false friend" ). Would you mind to explain a little more?
Yes, actually 'modality' is used with different meanings:
1 - a method of therapy that involves physical or electrical therapeutic treatment
2 - a particular sense (like hearing or taste)
It has other meanings too, but not as 'form' or 'way'
