Individuals diagnosed with FM patients experience lower self-esteem and positive affect, as well as greater levels of depression, anxiety, negative affect, and pain catastrophizing. Among those experiencing FM, clinical and experimental pain are associated with specific dispositional trait profiles, which are indexed by levels of negative affect and positive affect. Neuroinflammation and inflammation also play a role in FM- related affect and pain. Recent studies that have highlighted neuroinflammation and inflammation as physiological mechanisms associated with changes in dysregulated affect and chronic pain. Veterans with FM can ameliorate dispositional traits-i.e., increasing positive affect and reducing negative affect-by participating in exercise. However, a gap exists regarding how to optimally engage Veterans with FM in an exercise program. Thus, to fully take advantage of all potential therapeutic benefits of exercise for FM, there is a critical need to identify those factors underlying exercise engagement for FM pain management. The purpose for this study is to 1) determine associations of dispositional trait styles, neuroinflammation, and inflammation with pain outcomes in Veterans with FM; and 2) develop and design a Veteran-informed exercise program.","The investigators propose to recruit 30 Veterans with FM and 30 Veterans without FM who will undergo magnetic resonance spectroscopy imaging (MRSI) scans, pain assessments, and semi-structured interviews. The participants will undergo a 6-week moderate intensity continuous training exercise intervention and follow-up MRSI scans, pain assessments, and semi-structured interviews. The investigators central hypothesis is that dispositional trait styles, neuroinflammation, and inflammation will be associated with pain outcomes and exercise will induce beneficial anti-inflammatory changes. The research objective of this proposal is two-fold: 1) to acquire data on the associations between dispositional trait styles, neuroinflammation, inflammation, and pain in Veterans with FM and 2) to develop a Veteran-informed exercise program with potential to modify dispositional trait styles, neuroinflammation, inflammation, and pain in Veterans with FM.",[18],"Fibromyalgia",[20,21,22,23,18,24],"Chronic Pain","Inflammation","Affect","Neuroinflammation","Exercise","INTERVENTIONAL","SUPPORTIVE_CARE",[28],"NA",{"count":30,"type":31},60,"ESTIMATED",[33],{"type":34,"name":35,"description":36,"armGroupLabels":37},"BEHAVIORAL","Moderate Intensity Continuous Training","6-week structured exercise intervention.

Temporal summation is presumed to be the psychosocial manifestation of wind-up. Wind-up is a phenomenon where repetitive stimulation of C primary afferents at rates greater that 0.3 Hertz produces a slowly increasing response of second-order neurons in the spinal cord. Temporal summation will be assessed using a nylon monofilament calibrated to bend a 300g of pressure on the back of the hand and lower back. Participants will be instructed to provide a verbal 0-100 rating of pain following a single contact of the monofilament. Then, participants will be instructed to provide another 0-100 rating of pain following a series of 10 contacts of the monofilament.

Conditioned pain modulation is believed to reflect the perceptual manifestation of diffuse noxious inhibitory controls, whereby ascending projections from one noxious stimulus activate supraspinal structures that trigger descending inhibitory projections to the dorsal horn. Participants will undergo four cold pressor immersions that consists of placing the non-dominant hand, up to the wrist, into circulating cold water for up to 1 minute and will provide a 0-100 rating of pain. Following each immersion, a handheld force algometer will be applied to either the forearm or lower back and press a handheld button to indicate when the pressure first becomes painful.",{"measure":59,"description":60,"timeFrame":42},"C-reactive protein","A marker of pro-inflammation from blood draws",{"measure":62,"description":60,"timeFrame":42},"Tumor necrosis factor- alpha",{"measure":64,"description":60,"timeFrame":42},"Interleukin-6",{"measure":66,"description":60,"timeFrame":42},"Interleukin- 10",{"measure":68,"description":60,"timeFrame":42},"Interleukin- 8",{"measure":70,"description":71,"timeFrame":42},"Myo-inositol","marker of neuroinflammation measured via magnetic resonance spectroscopy imaging.",{"measure":73,"description":71,"timeFrame":42},"N-acetylaspartate",{"measure":75,"description":71,"timeFrame":42},"Choline",{"measure":77,"description":71,"timeFrame":42},"Lactate",{"measure":79,"description":71,"timeFrame":42},"Creatine",{"measure":81,"description":82,"timeFrame":42},"Brain Temperature","marker of neuroinflammation using absolute brain temperatures (in °C) from magnetic resonance spectroscopy imaging.",{"measure":84,"description":85,"timeFrame":42},"Exercise Benefits and Barriers","Participants will be asked to complete the Exercise Barriers and Benefits Scale that assesses perceived benefits and barriers to exercise to rank agreement with 29 statements, where 4='strongly agree' and 1='strongly disagree.'",{"measure":87,"description":88,"timeFrame":42},"Exercise Perceptions","Semi-structured interviews will be conducted around topics related to current exercise behavior and any barriers the participants have to current exercise behavior, and will elicit participants' views on what an ideal exercise program would be.",[],"ALL","19 Years","85 Years",true,{"inclusion":95,"exclusion":102,"raw_text":114},[96,97,98,99,100,101],"Widespread pain index (WPI) 7 and symptom severity scale (SSS) score 5 OR WPI 4-6 and SSS score 9","Generalized pain, defined as pain in at least 4 of 5 regions, is present","Symptoms have been present at a similar level for at least 3 months","A diagnosis of FM is valid irrespective of other diagnoses.
