Sleep and Pain Intervention for Chronic Widespread Pain Pilot Study

University of Missouri-Columbia20 enrolled

Overview

This randomized controlled clinical trial will examine the effects of Cognitive Behavioral Therapy (CBT-) in patients with comorbid chronic widespread pain (CWP) and insomnia. Specific Aims: 1. To examine the clinical and health characteristics, including sleep, pain, fatigue, cognitive abilities, and cardiovascular health in patients with comorbid CWP and insomnia. 2. To examine changes in the primary clinical outcomes, including chronic pain, complaints of poor sleep, and fatigue compared to the waitlist control (WLC). 3. To examine changes in the secondary clinical outcomes, including mood, daytime functioning, cognitive functioning, and cardiovascular health compared WLC. 4. To examine the mechanistic variables, including arousal (heart rate variability, HRV), CS (thermal response) and neural plasticity (brain function and structure) - compared to WLC.

This randomized controlled clinical trial will examine the effects of CBT in patients with chronic widespread pain and insomnia. Sample will include 20 patients (\[18\]-65 years) who satisfy criteria for chronic widespread pain and insomnia. Participants will be randomly assigned to CBT or waitlist control. All participants randomized to the cognitive-behavioral interventions will receive 4 treatment sessions (\~50 minutes each). Baseline, posttreatment, \[\& 3-mo.\] follow-up assessments will include measures of sleep, pain, thermal pain response, heart rate variability, brain structure and functions, affect, cognitive functioning, cardiovascular health, and substance use.

Outcomes

Primary Outcomes

Change in self-reported ratings of Pain Sensitivity and Pain Unpleasantness on Daily Diaries

Participants will rate how much pain they experience and how unpleasant the pain is on a scale of 1 to 100 on the daily dairies. Analysis will involve examining the trend of changes in these ratings.

Time frame: Participants will complete the pain ratings daily for 56 days from Baseline to Post-Treatment , and for 14 days in 3-month Follow-Up (Week 21-22)

Change in pain severity assessed by the McGill Pain Questionnaire

The McGill Pain Questionnaire will be administered three times - baseline, post-treatment, and follow-up. Analysis will involve examining the trend of change in the scores in McGill Pain Questionnaire.

Time frame: Pre-treatment (week1 or 2), post-treatment (week7 or 8), follow-up (week 21 or 22)

Change in pain-associated disability assessed by the Pain Disability Questionnaire

The Pain Disability Questionnaire will be administered three times - baseline, post-treatment, and follow-up. Analysis will involve examining the trend of change in the scores in Pain Disability Questionnaire.

Time frame: Pre-treatment (week1 or 2), post-treatment (week7 or 8), follow-up (week 21 or 22)

Change in Self-Reported Bedtime, Wake time, Sleep Onset Latency, Wake After Sleep Onset, Sleep Quality on the Daily Diaries

Participants will answer the following questions on the daily diaries: 1. I napped for \_\_\_\_\_\_\_\_\_\_\_\_ minutes yesterday. 2. I napped \_\_\_\_\_\_ times yesterday. 3. I napped in the \_\_\_morning \_\_\_afternoon \_\_\_\_evening (check all that apply) 4. I went to bed last night at \_\_\_\_\_\_\_\_\_\_\_\_ AM/PM. 5. It took me \_\_\_\_\_\_\_\_\_\_\_\_ minutes to fall asleep. 6. I woke up \_\_\_\_\_\_\_\_\_\_\_\_ times last night. 7. I was awake for \_\_\_\_\_\_\_\_\_\_\_\_ minutes in the middle of the night. 8. My final wake up time was \_\_\_\_\_\_\_\_\_\_\_\_ AM/PM. 9. I got out of bed at \_\_\_\_\_\_\_\_\_\_\_\_ AM/PM. 10. I would rate my quality of sleep last night as \_\_\_\_\_\_\_\_\_\_\_\_. 1\. very poor 2. poor 3. fair. 4 good 5. Excellent

Time frame: Participants will complete the sleep questions daily for 56 days from Baseline to Post-Treatment , and for 14 days in 3-month Follow-Up (Week 21-22)

Change in Bedtime, Wake time, Sleep Onset Latency, and Wake After Sleep Onset measured by Actigraphy

Actiwatch-L (ACT-L; Mini Mitter, Inc.) will be used to obtain a behavioral measure of sleep outcome. ACT-L is a wristwatch-like device that provides long-term monitoring of ambient light exposure and gross motor activity in human subjects. The Actiware-Sleep software provides behavioral estimates for several sleep variables: (1) sleep onset latency-interval between bedtime and sleep start; (2) total sleep time-sum of all sleep epochs within the sleep period; (3) sleep efficiency percentage- ratio of total sleep time to total time spent in bed × 100; and (4) total wake time-sum of all wake epochs within the sleep period.

Time frame: Daily from the start of the study to post-treatment (week1 to week8), two-week daily reports in 3-mo follow up (week21,week22)

Change in Insomnia Severity Index

The Insomnia Severity Index will be administered three times - baseline, post-treatment, and follow-up. Analysis will involve examining the trend of change in the Insomnia Severity Index.

Time frame: Pre-treatment (week1 or 2), post-treatment (week7 or 8), follow-up (week 21 or 22)

Secondary Outcomes

Change in heart rate variability

Time frame: Pre-treatment (week1 or 2), post-treatment (week7 or 8), follow-up (week 21 or 22)

Change in Body Mass Index

Time frame: Pre-treatment (week1 or 2), post-treatment (week7 or 8), follow-up (week 21 or 22)

Change in Cognitive Functioning measured by the NIH toolbox Cognitive Domain

Time frame: Pre-treatment (week1 or 2), post-treatment (week7 or 8), follow-up (week 21 or 22)

Day-to-day change in Cognitive Functioning measured by the Cognitive Diary

Time frame: Participants will complete cognitive diary daily for 56 days from Baseline to Post-Treatment , and for 14 days in 3-month Follow-Up (Week 21-22)

Change in daily substance use

Participants will answer these questions: Drug Used\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ Prescription Drug? Y/N If yes, used as directed? Y/N Amount taken\_\_\_\_\_\_\_\_\_\_\_\_\_\_ Time taken\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

Time frame: Participants will report daily substance use for 56 days from Baseline to Post-Treatment , and for 14 days in 3-month Follow-Up (Week 21-22)

Change in Thermal Pain Response

Participants will undergo quantitative sensory testing using a contact thermode applied to the volar surface of the forearm. The protocol that will assess both first pain (primarily A-delta function) and second pain (primarily C-fiber input). All thermal stimuli will be delivered using a computer-controlled Medoc Thermal Sensory Analyzer (TSA-2001, Ramat Yishai, Israel). Visual Analog Scale (VAS) ratings of 4 graded intensities (45, 47, 49, 51° C) of 5 second temperature stimuli will be obtained in the following fashion: Stimulus presentation will be timed such that no site is stimulated with less than a 3-minute interval to avoid sensitization of the site. Participants will rate 8 stimuli (2 at each intensity) using a VAS for pain intensity anchored at the right end by "the most intense pain imaginable." A second random sequence of 8 stimuli (2 at each intensity) will be rated by VAS for pain unpleasantness.

Time frame: Pre-treatment (week1 or 2), post-treatment (week7 or 8), follow-up (week 21 or 22)
