Hiya
For me it would definitely depend on which IHM course you have done and what type of therapist you are...there are many therapists that do not treat people with anything out of the ordinary....i am not one, i do lots of rehab work and have never had to turn anyone away.
If you have only do the one day course and have no knowledge of A&P and medical conditions and the possibles reactions they may experience I would be cautious, however if you have done A&P and have a good understanding of illness etc then go for it, at all times follow your feelings. The only one I would treat with real caution with IHM is epilepsy where i would only do gentle tapotment and soothing moves but yes i would still treat. In terms of medication as a general rule of thumb if a client has been medicated on the same drugs for 3-6months and has been stable all this time again I would be inclined to treat.
If you are treating diabetics and why not make sure you have some dextrose tablets (any chemist or supermarket), they will know if they are going hypo and this will only happen if they are insulin dependent. I generally try to ensure if they are injecting that the insulin has been taken at least an hour before treatment.
I do a small consultation and yes the sign the forms.....i do not see why this could still not be the case...most blind people will be able to put the sig. down if you show them where. Make sure you explain the treatment thoroughly and ask if they want guidance anywhere, surprises are not nice at any time.
Hope that helps
