An NLP intervention demands a great deal on the skill of the practitioner. It does not work 'objectively' and independently of the practitioner and the patient in the way that a drug is supposed to. It would be impossible to conduct trials where neither the patient nor the practitioner knows who is receiving the treatment. It is possible however, to do a study so that the evaluating medical professional is unaware who received the treatment and who was in the control group. There is a good study showing the ffectiveness of NLP in asthma.
Rapport is crucial.
When a person is hurt or ill, they need to trust the medical professional and they need emotional support. My goal here was to evaluate the effectiveness of the NLP approach I used, so I was flexible within that goal, even though I used the same intervention on every participant. I hope this and my preceding article has given you a flavour of the possibilities of using NLP with sports injuries. I will be doing more research in this field.
