Acupuncture Therapy, Fibromyalgia, Physician-patient Relationship

Brief summary

The overall aim of the present proposal is to investigate how patients' and clinicians' (Licensed acupuncturists, LAc) neural and autonomic processes during treatment interaction correlate to patient outcomes. Male and female healthy clinicians and fibromyalgia patients will be recruited for the study.

Detailed description

First phase: At the training sessions, both clinician and patient will fill out a set of questionnaires and go through standardized psychophysical tests for assessing visual displays of affect. They will also be informed of the efficacy of the electroacupuncture in relieving pain during the experiment. During the clinical examination, the clinician will follow clinical exam protocol and do an intake of the fibromyalgia (FM) patient, including a physical exam and pain assessment. While in the scanner, the clinician will receive painful stimulations with a pressure cuff on the leg over an 8-minute paradigm in order to get cerebral representation. The patient will then be placed in a different scanner running simultaneously and will experience painful stimulations with a pressure cuff while interacting via live camera with the clinician in the other scanner. When visually prompted via cues on a screen, the clinician will activate analgesia for the patient, through a response device (response box) in clinician's one hand. After each trial of pain with/without treatment, the clinicians will be asked how did you feel about the outcome (extremely positive - extremely negative), and how satisfied are you (Not at all satisfied - Very satisfied) on Numerical Rating Scales (NRS). The patient will also give ratings after each trial of pain with/without treatment. They will be asked how did you feel about the outcome (extremely positive - extremely negative)?, and how painful was the cuff (Not painful - Extremely painful)? on NRS. After the scan, both clinician and patient will be asked to rate anxiety during the presence of visual stimulus preceding cuff activation (not at all anxious - extremely anxious). After the final MRI session, the clinician and the patient will both be given the chance to report their responses to the treatment and then debriefed. Second phase: At training session both clinician and patient will fill out a set of questionnaires. During the first MRI session the clinician will receive painful stimulations with a pressure cuff on the leg over a 6-minute paradigm in order to get cerebral representation. The patient will then be placed in a different scanner running simultaneously and will experience pain stimulation with the pressure cuff while interacting via live camera with the clinician in the other scanner. When visually prompted via cues on a screen, the clinician will activate analgesia for the patient, through a response device (response box) in clinician's hand. Both patient and acupuncturist will be asked to give ratings of pain and other parameters during the scan. Following the first MRI session, the patient will attend biweekly acupuncture treatment sessions with the clinician (6 treatments total). During the first session the clinician will be introduced to the patient and do a general intake in addition to the acupuncture treatment. The final MRI session will be identical to the first.

Interventions

DEVICEElectroacupuncture Analgesia

For the MRI sessions, acupuncture needles will be inserted next to the cuff placed on the left leg and will be connected to electrodes. Low-amplitude electrical current will be activated when a button is pressed via a handheld device, controlled by the acupuncturist, in order to reduce pain, acting as an analgesic. Additionally, electroacupuncture-induced analgesia will be used for the treatments. During the treatment sessions the acupuncturist will insert needles in several locations aimed to reduce the patient's fibromyalgia pain. Low-amplitude electrical current will be activated by the acupuncturist using the same electroacupuncture device as in the MRI machine.

DEVICEHokanson Rapid Cuff Inflator

The Hokanson Rapid Cuff Inflator will be placed on the lower right leg of the subject and utilized for pain testing purposes according to the protocol. Ascending pressures will be administered using the cuff to elicit different pain intensities.

Inclusion criteria

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
