SIT is a broad term. Many of the individual therapies are part of therapies outside the SIT protocol.

What therapy helped with your dizziness ?

It helps to break down the many symptoms/struggles and address them individually. It a therapy that works for a particular symptom is also a part of SIT, it does not validate all of SIT. Same goes for any therapy.

There are many therapies that claim to reduce or cure specific conditions. Any one may help a specific person but not many others. This may be due to actual therapeutic benefits or it may be due to the placebo effect. There are some therapies that claim to resolve a specific condition but the simple exercise of relaxing and submitting to the therapy may be the most effectual part of the therapy.

It is a waste of effort to constantly be comparing outcomes between different persons. There may be general comparative value but rarely is there any specific comparative value.

The best value may be the observations of how the therapist relates to the PCS symptoms. If the therapist say, "Sure, I can fix that. It will usually only take 10 sessions at $140 per session."

We need to be careful that we are not Cash Cows for these therapists. Being desperate to get better can set us up for exaggerated claims. Often, those exaggerated claims are our fault as we grab at a few terms that sound promising while neglecting to take into consideration other parts of the presentation.
