Measurement Requirements

This trial is evaluating whether Treatment will improve 1 primary outcome, 3 secondary outcomes, and 7 other outcomes in patients with Chronic Pain. Measurement will happen over the course of 2 years.

Neuropathic Pain Questionnaire
The Neuropathic pain Questionnaire (NPQ) is an assessment instrument for neuropathic pain intensity and quality. It contains 12 items: 10 related to sensations or sensory responses and two related to affect. The items are totaled and rated out of 12, with 12 being in the most neuropathic pain.
Becks Depression Inventory
The Becks Depression Inventory is commonly used assessment tools to quantify and track depression mood state over time. Its a single value outcome measurement ranging from 0 to 63, with 63 being the most depressed.
NIH PROMIS toolbox (Patient Impression)
The NIH PROMIS toolbox contains a host of survey questions tailored to measurement of specific disease states such as pain, global health and function. The patient impression evaluates patient self-evaluation and physician evaluation of the patient's general health ranging form 0 to 7 with 7 being the worst general health.
Activity Tracker (Fitbit) - Activity (Steps)
Each patient will be given a fitbit activity monitor which can record steps taken, flights of stairs climbed, heart rate and sleep quality. These measures will be used to infer functional improvement over time. Steps will be recorded as steps per hour or day and evaluated against changes in pain level reported in the VAS or NRS.
Activity Tracker (Fitbit) - Activity (Sleep)
Each patient will be given a fitbit activity monitor which can record steps taken, flights of stairs climbed, heart rate and sleep quality. These measures will be used to infer functional improvement over time. Sleep quality will be evaluated using the parameters (time in bed, time asleep, time in REM sleep, time in non-REM sleep, time awake).
Quantitative Sensory Testing Pain Threshold
The Quantative Sensory Testing machine is described in the research protocol, and uses thermal stimuli to measure pain sensitivity and thresholds which may change with time or therapy. Thermal stimuli down to 0 degrees F. and up to 55 degrees F are given and patients are asked to report their pain either qualitatively or quantitatively using numerical rating scale from 0 to 10, with 0 being the lowest/no pain, and 10 being the worst.

What is chronic pain?

The definition of chronic pain has never been resolved in any of the scientific publications cited in this paper. It is often assumed that chronic pain in the absence of other associated symptoms is a normal one; a condition in some individuals that resolves on its own. However, there are more than 25 known reasons for chronic pain, that include neurological processes, emotional trauma and genetic factors. More than one definition of chronic pain is emerging. It comes to mind as a “disabling chronic pain syndrome” of unknown causation and pathophysiology that can and often does last an entire life...

What is the average age someone gets chronic pain?

A new age of onset for [chronic pain]( seems to have moved back to the mid-1960's. The majority had their initial symptoms prior to adulthood. No particular risk factors were identified for age of onset of chronic pain. It is a matter of speculation that early-onset chronic pain might be linked to increased vulnerability to pain syndromes, psychiatric disease, or multiple pain treatments.

What is the latest research for chronic pain?

The information presented herein is a valuable tool for practitioners to consult. The authors and readers of this paper have tried to give as wide of a range of evidence as they could for each topic under investigation to allow the reader to make up their own mind. While this information and that presented will provide the general audience with an overview of what is being investigated, the real experts will have already seen more of this information in their daily practice with patients who have chronic pain and who are candidates for further research. The authors would thank those members of The Cochrane Group, The IADP Research Group, The CNCP Trial Group, and the PROFILES trial group for this supplementary information.

What is treatment?

“There is no answer that can bring one peace or comfort, but there are two important things we should focus on to find comfort,” according to a woman suffering from Fibromyalgia. She explained that “everything” that we need for treatment…even an understanding and an open mind…come from loving each other. “If we don’t understand each other, we don’t understand ourselves, and don’t understand our pain, it’s impossible to find comfort….

Anonymous Patient Answer

Who should consider clinical trials for chronic pain?

In a recent study, findings show that [chronic pain]( patients want clinical trials in order to help understand how we can better treat them. However, they want to have an open discussion with investigators, discuss all risks and benefits, and understand the steps/processes involved before participation in clinical trials. They also want a better message about enrollment in clinical trials. They also want treatment from surgeons and other providers rather than clinical trials. They also want to be able to decide if treatment is a good idea for them. Most of the patients want clinical trials for treatment options that include acupuncture and chiropractic. Most of the patients want clinical trials that measure outcomes that include mood or quality of life rather than just pain.
