While I can see the value of ultrasound in building a therapeutic relationship and possibly a placebo effect, is this fair to the patient? This comes back to a patient's right to autonomy, information sharing, and informed consent. If I explained to a patient, "I'm about to apply a treatment to you that has almost no supporting evidence in humans", would this influence their agreement to that treatment? In regards to establishing a therapeutic relationship, I feel this can be established with methods that have less risks and contraindications.
