About this study
Official title: Neurobiological Mediators of Self-Regulatory and Reward-Based Motivational Predictors of Exercise Maintenance in Chronic Pain and PTSD
The primary purpose of the R21 is using an experimental medicine research approach to study whether a chronic, progressive-based exercise program will help Veterans suffering from chronic low back pain (cLBP) and PTSD achieve exercise maintenance, and shared symptom reduction, through neuropeptide Y mediated improvements in putative factors (self-regulation and reward sensitivity) known to improve exercise related self-efficacy and motivation.
Read the detailed description
This study will compare the effects of a 3-month, individually prescribed progressive exercise training program on: 1) chronic low back pain (cLBP), depression and PTSD symptoms, and 2) neurobiological and related neuropsychological mechanisms by which our exercise-training paradigm may foster exercise maintenance. More specifically, the investigators hypothesize relationships between exercise-training associated augmentation of neuropeptide Y (NPY) system function and improved capacities for reward and self-regulation-neuropsychological capacities posited to underlie intrinsic motivation and self-efficacy, which in turn have been shown to predict exercise maintenance. This study will focus on Veterans with cLBP/PTSD. The study design includes a baseline, acute, cardiopulmonary exercise assessment (CPX) that will inform the exercise prescription for the 12-week "progressive exercise" training program, comprised of three 30-45 minute in clinic exercise sessions per week (walking or running--depending on the ability/capacity of the participant). All exercise sessions will be supervised by an exercise physiologist in the Clinical Studies Unit (CSU) at VA Boston Healthcare System. Intermittent telephone calls by the researchers will provide additional motivational support and problem solving. Implementation of the prescribed exercise regimen will also be supported by the use of heart rate and actigraph monitors programmed for the participant to achieve their prescribed heart rate range (HRR). Also, a "midpoint" and "endpoint" CPX assessment will track changes in NPY system function and delineate their impact on pain, depression and PTSD symptoms, as well as the factors proposed to foster exercise maintenance. All three CPX tests will be performed in accordance with guidelines published by the American College of Cardiology. Among Veterans with cLBP/PTSD, the investigators hypothesize that the capacity to release NPY in response to vigorous exercise (i.e., acute CPX testing) will be associated with improvements in pain, depression and PTSD symptoms, as well as the putative factors that predict exercise maintenance. Data from this R21 will be used to demonstrate feasibility and inform the further development of individually prescribed, motivationally based exercise regimens that could be used as adjuncts to cognitive and other therapeutic PTSD, depression or chronic pain interventions to reduce cLBP, depression and PTSD, as well as the negative consequences of these disorders over the long-term.
*Note: mandatory covid precautions due to the pandemic led to an initial suspension of all study activities in 2020 after just one of the consented enrolled participants was randomized into the 'progressive exercise' study arm. That participant completed only half of the 12 week intervention. In addition, this participant had one adverse event after a stress test which was determined to be unrelated to the study intervention. Despite intentions to resume the research, a decision was made to terminate the study in early 2022 given the recruitment and intervention challenges with the pandemic surge and the end of funding. No data wee collected related to any of the study outcome measures so no outcome measures are reported.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Progressive exercise trainingBehavioural
The 12 week progressive exercise program gradually increases the walking/running intensity and length of exercise every 2 weeks for the first 6 weeks and then maintains the higher intensity level for weeks 7-12,. The exercise intensity is based on percentile targets defined by the baseline cardiopulmonary test (CPX test). Participants will be called at weeks 4 and 10 to assess and foster exercise motivation, using basic principles of motivational interviewing..
Waitlist ControlBehavioural
Participants will be screened for eligibility and if randomized into the waitlist control group. Wait list participants will wait for 12-weeks before they can participate in the progressive exercise training program. The 12 week progressive exercise program is identical to the one used in the intervention group. Specifically, the 12 week progressive exercise program gradually increases the walking/running intensity and length of exercise every 2 weeks for the first 6 weeks and then maintains the higher intensity level for weeks 7-12. The exercise intensity is based on percentile targets defined by the baseline cardiopulmonary test (CPX test). Participants will be called at weeks 4 and 10 to assess and foster exercise motivation, using basic principles of motivational interviewing.
| Study group | Role | What they receive |
|---|---|---|
| Progressive exercise program | Experimental | Based on the "Active Physical Treatment Model" individuals with chronic pain are typically and primarily sedentary or physically deconditioned and need a progressive approach to work up to standard exercise prescriptions as defined by the American College of Sports Medicine. Thus, progressive exercise training can help to minimize the risk or occurrence of a range of exercise-related adverse medical events, particularly with the complex study population which will be starting at a sedentary level and therefore, may not be able to initially achieve the heart rate goals prescribed in standard exercise training protocols. The exercise prescription will be individually designed and geared toward an intensity manageable by the individual. Receives: Behavioral: Progressive exercise training |
| Waitlist Control | Active comparator | The waitlist control participants will be fully screened for eligibility and asked to wait 12 weeks before beginning the 12-week progressive exercise program. They will be assessed again at the end of the 12-week waiting period. These patients will then be compared to patients in the experimental arm and then compared against their own waitlist control data after completing the 12-week exercise program. The exercise program that the waitlist control patients will participate in is identical to the experimental arm. Receives: Behavioral: Waitlist Control |
What is being measured
The primary outcome is the main question the study is designed to answer.
Transtheoretical Model of Exercise: Stages of Change (Short-form)
This 4-item continuous measure categorizes stages of behavioral change based on the Transtheoretical Model (TTM) stages (precontemplation, contemplation, preparation, action and maintenance), specifically in the context of exercise behavior change. Each stage reflects a different level of readiness to exercise, where precontemplation means that the patient is not actively considering exercise behaviors, whereas a patient in the maintenance stage has been actively exercise regularly (3 times per week for 50 minutes minimum) for at least the past 6 months. Scoring for this measure is determined by YES or NO answers provided to questions about exercise behaviors that patients are currently doing or intend to do in the near future. For example, if patients answer YES to the first question "Do you currently engage in regular exercise (at least 3 times per week for 50 or more minutes per session)?", then the patient could either be in the action or maintenance stage of exercise.

Secondary outcomes (2)
West Haven Yale Multidimensional Pain Inventory - Pain Interference
The West Haven Yale Multidimensional Pain Inventory (WHYMPI) has been demonstrated to be applicable across a variety of clinical pain conditions, and this subscale focuses on pain interference. Participants identify a "significant other" defined as a person with whom the participant feels closest to by checking off one of 7 descriptive terms that best represents the relationship with this person and if the participant shares a living space with that person. Next are 20 items about the impact of pain on the participant's life and are scored on a 7-point scale from 0 to 6. Some questions are reverse coded and a higher overall score indicates greater pain interference. Some anchors for 0 to 6 include "No pain/Very intense pain," "No interference/Extreme interference," "No change/Extreme change," "Not at all supportive/Extremely supportive," and "Extremely low mood/Extremely high mood."
Measured: Eligibility/Screening, baseline, 6 week, 12 week
Clinician-Administered PTSD Scale-5
The CAPS is the gold standard in PTSD assessment. The CAPS-5 is a 30-item structured interview that can be used to make a current (past month) diagnosis of PTSD, lifetime diagnosis of PTD, and assesses PTSD symptoms over the past week. The patient identifies a Criterion A index trauma and the assessor combines information about frequency and intensity of each item into a single severity rating. CAPS-5 total symptom severity score is calculated by summing severity scores for the 20 DSM-5 PTSD symptoms. CAPS-5 symptom cluster severity scores are calculated by summing the individual item severity scores for symptoms corresponding to a given DSM-5 cluster: Criterion B (items 1-5); Criterion C (items 6-7); Criterion D (items 8-14); and, Criterion E (items 15-20). A symptom cluster score may also be calculated for dissociation by summing items 19 and 20. Criterion items are scored 0 to 4 (Absent to Extreme/incapacitating) and summed up. Higher scores indicate greater severity of PTSD.
Measured: Eligibility/screening and 12 week
