The easiest and most accurate MRT is that performed to assess musculoskeletal issues (ex: how to apply a physical manipulative therapy to a specific area). The reason for this is because you are operating within the nature of MRT: ideomotor action is all about the neuromuscular system. With MRT there is always an idea associated with the test. Merely touching an area of trauma is not going to make all the muscles go weak – there needs to be a question on the muscle; such as “is there a problem here?”. We often hold an injured area for support as we use it – this supports the area vs making everything go weak.
It does not serve the body’s survival programming to neurologically weaken all the body’s muscles at a time when we may need both injury support and strength. In fact we are actually programmed to hold an injured area for support. MRT shows a weakened muscle only when the intent of the therapist is looking for a problem. Once a problem is identified, we can move the tissue of the injured area in different directions to see which way strengthens the MRT. Once again we see that touching an injured area produces a strengthening, not a weakening. MRT requires a question.
Even with the most basic medical neurological muscle strength testing, the idea shared by doctor and patient is to “hold as strong as you can”, in order to evaluate how well nerve signals are getting to the muscle. A distracted patient can not do this – a focus needs to be held. Everything human beings do requires an intent and focus – this is not a reason to discount MRT, it is just the way things work in our bodies – so we make use of this mechanism as a therapeutic tool.
