Hi Citygal,
I guess it is really difficult to comment on your situation, as we don't exactly know what kind of machine is used, what the machine actually does and the rational behind the treatment.
Which is sort of exactly my point.
Under the Patient Code of Rights for any country, you need to give informed consent to any treatment applied to you.
This includes full information (verbal and or written)and explanation about the treatment you receive and any available treatment alternatives.
Please ask your Therapist what the treatment consists of and why she/ he believes this is the best treatment option.
We know that there is a psychological component to recovery and if you cannot fully commit to the treatment, because you don't understand what is happening and you have fears or doubts in regards to the treatment you receive, the success of the treament is likely to be less than optimal.
Again, talk to your therapist (she/he might not even be aware that you don't know what's going on...) and you'll be much happier.
Regards,
Fyzzio
