Pain, Psychological, and Endocannabinoid Responses to Yoga in Breast Cancer Survivors With Chemotherapy-induced Neuropathic Pain

March 18, 2020 updated by: University of Wisconsin, Madison
This study evaluates the acute effect of aerobic exercise and yoga on pain, plasma levels of endocannabinoids, and mood (i.e., mood disturbance and anxiety). Participants will complete three separate sessions on different days. The first session is a familiarization session in which participants complete questionnaires and are familiarized with the experimental protocols. During the second and third sessions, outcomes are measured before and after the participants complete either 44 minutes of moderate aerobic exercise (i.e., walking on a treadmill) or 44 minutes of yoga.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

  • presence of painful polyneuropathy, with onset coinciding or developing after receiving chemotherapy agents that in the opinion of the research team is likely to have caused such symptoms,
  • at least six months since last active cancer treatment, with no further planned treatment (Note. active treatment is defined as surgery, chemotherapy, or radiation),
  • the participant agrees to use the safety stop feature on the treadmill if needed,
  • at least 18 years of age,
  • and their physicians has provided consent for them to participate in yoga and aerobic exercise sessions.

Exclusion Criteria:

  • Undergoing current chemotherapy or radiation treatment for cancer,
  • taking anticoagulant therapy,
  • uncontrolled medical conditions (i.e., uncontrolled hypertension, heart disease, stage 4 liver disease, end-stage renal disease, end-stage pulmonary disease, etc),
  • stroke or myocardial infarction in the past 6 months,
  • being pregnant or planning to become pregnant,
  • severe mobility constraints (e.g., confined to a wheelchair),
  • having a history of light headedness or fainting during blood draws or physical activity.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Neuropathic Pain Sensations as determined by VAS
Time Frame: This will be measured 2 times during each experimental session- once before the assigned exercise task (i.e., baseline) and once upon task completion (i.e., approx. 50 mins later), approximately week 1 and week 2 on study.
Visual analog scales (VAS) will be used to assess the intensity of the following sensations specific to neuropathic pain: pins and needles, tingles, stinging, and electrical pain sensations. The VAS is measured on a 100mm scale ranging from "No Pain" to "Worst Imaginable Pain."
This will be measured 2 times during each experimental session- once before the assigned exercise task (i.e., baseline) and once upon task completion (i.e., approx. 50 mins later), approximately week 1 and week 2 on study.
Change in cold pain threshold
Time Frame: This will be measured 2 times during each experimental session- once before the assigned exercise task (i.e., baseline) and once upon task completion (i.e., approx. 50 mins later), approximately week 1 and week 2 on study.
The minimum cold temperature needed to elicit a pain response.
This will be measured 2 times during each experimental session- once before the assigned exercise task (i.e., baseline) and once upon task completion (i.e., approx. 50 mins later), approximately week 1 and week 2 on study.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in total mood disturbance (Profile of Mood States)
Time Frame: This will be measured 2 times during each experimental session- once before the assigned exercise task (i.e., baseline) and once upon task completion (i.e., approx. 50 mins later), approximately week 1 and week 2 on study.
65-item self-reported mood questionnaire that measures mood "right now." Scores range from 0-200 with higher scores indicating higher mood disturbance.
This will be measured 2 times during each experimental session- once before the assigned exercise task (i.e., baseline) and once upon task completion (i.e., approx. 50 mins later), approximately week 1 and week 2 on study.
Change in plasma concentration of 2-Arachidonoylglycerol (2-AG)
Time Frame: This will be measured 2 times during each experimental session- once before the assigned exercise task (i.e., baseline) and once upon task completion (i.e., approx. 50 mins later), approximately week 1 and week 2 on study.
Plasma concentration of 2-AG, one effector of the endocannabinoid system
This will be measured 2 times during each experimental session- once before the assigned exercise task (i.e., baseline) and once upon task completion (i.e., approx. 50 mins later), approximately week 1 and week 2 on study.
