Acupuncture's pain relief tied to brain synchrony between patient and practitioner

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Phase 1: Inclusion Criteria (Healthy Clinicians): * Male and Female healthy clinicians * 25-60 years of age * Ability to read and understand English; English can be a second language provided that the participant feels that he/she understand all the questions used in the assessment measures. Inclusion Criteria (Fibromyalgia Patients): * Have a clinical diagnosis of fibromyalgia and meet the Wolfe et al 2011 research criteria for fibromyalgia for at least one year * Are on stable doses of medication for 30 days prior to entering the study and agree not to change medications or dosages during the trial * 21 to 60 years of age * Right-handed * Ability to read and understand English; English can be a second language provided that the participant feels that he/she understand all the questions used in the assessment measures Exclusion Criteria (All participants): * Any longer period of work experience involving pain treatment, pain rehabilitation etc. This is in order to exclude participants with biased expectations regarding different methods of analgesia * Presence of any illness or medication use that is judged to interfere with the trial. For example: psychiatric disorder according to the DSM-IV manual, medication that can influence cognition or emotional processing, i.e. sleep medication, antidepressants, anti-convulsants or opioids * Presence of any contraindications to fMRI scanning. For example: cardiac pacemaker, metal implants, fear of closed spaces, pregnancy * Inability to respond accurately to the pain-relieving intervention in the behavioral part of the experiment, indicating a lack of response to the expectancy manipulation. If the healthy volunteer or clinician is not a responder to the behavioral expectancy induction he or she will be excluded * Unwillingness to receive brief experimental pain * Leg pain or health issues that may interfere with the study procedures Exclusion Criteria (Specific to Fibromyalgia Patients): * Comorbid acute pain condition * Comorbid chronic pain condition that is rated by the subject as more painful than fibromyalgia * Current use of opioid analgesics or stimulant medications or the fatigue associated with sleep apnea or shift work (e.g., modafinil) * Documented peripheral neuropathy * Any psychiatric disorder involving a history of psychosis (e. g schizophrenia, bipolar disorder, severe personality disorders) * History of anxiety disorders or significant anxiety symptoms interfering with fMRI procedures (e.g., panic) * Psychiatric hospitalization in the past 6 months * Any impairment, activity or situation that in the judgment of the Study Coordinator or Principal Investigator would prevent satisfactory completion of the study protocol. * Is an actual clinical patient of the clinician subject Phase 2: Inclusion Criteria (healthy individuals): 1.
