Trial Outcomes & Findings for Chronic Low Back Pain and Meditation (NCT NCT04034004)

NCT ID: NCT04034004

Last Updated: 2023-10-11

Results Overview

Numerical pain ratings (NRS) will be assessed while lying on the back and in response to the straight leg raise test (SLR). Pain ratings will be collected during SLR 1 and SLR 2 in the baseline, saline and naloxone sessions, respectively. The 11 point scan will include a minimum rating of "0" which is characterized as "no pain" whereas the maximum ("10") is labeled as "most intense imaginable"." Higher numbers correspond to higher pain.

Participant Flow

500 individuals were screened for eligibility through the UCSD Recruitment services and study flyers. Enrollment started in January 2021 and data collection was completed in December of 2022.

88 out of the 500 individuals were enrolled and participated in the baseline session. Seventeen out of the 88 were not randomized for the following reasons: Not responsive to straight leg raise test (n = 4), Intolerance to pain procedures (n = 3), Withdrew (n = 3), Scheduling issues (n = 1), Transportation issues (n = 1), Positive opioid test (n = 1), Inappropriate behavior (n = 1), Other pain management (n = 1), instruction incomprehension (n = 1) and Mindfulness experience (n = 1).

Measure
Mindfulness Meditation and Saline First
After providing informed consent, 18 participants completed baseline testing. Participants then completed a four session mindfulness meditation intervention where participants were taught that perceived sensory events are "momentary" and "fleeting" and require no further evaluation. One participant dropped out after the first intervention session. After their respective intervention, these participants received IV saline in session 6. Two participants were dismissed because of trouble administering the IV. Saline: A 0.15 mg/kg bolus dose of saline in 25ml normal saline will be administered over 10 minutes. The investigators also will administer a supplementary IV infusion dose of 0.1mg/kg/hour saline immediately after bolus infusion will cease till the end of the experiment. After a two day washout period, 15 participants returned to the clinic and performed the naloxone infusion in session 7. Naloxone: A 0.15 mg/kg bolus dose of naloxone (Naloxone hydrochloride, Amphastar Pharmaceuticals, Inc., Rancho Cucamonga, California) in 25ml normal saline will be administered over 10 minutes. The investigators also administered a supplementary IV infusion dose of 0.1mg/kg/hour naloxone immediately after bolus infusion will cease till the end of the experiment.
Non Mindfulness Meditation and Saline First
After providing informed consent, 18 participants completed baseline testing. 2 participants withdrew from this session Participants then completed a four session non-mindfulness meditation intervention where participants were taught to independently practice closing their eyes and take a deep breath every few minutes. After their respective intervention, these participants received IV saline in session 6. One participants was dismissed because of trouble administering the IV. After a two day washout period, 15 participants returned to the clinic and performed the naloxone infusion in session 7.
Mindfulness Meditation and Naloxone First
After providing informed consent, 17 participants participated in baseline testing. Two participants withdrew for scheduling issues after baseline. Fifteen participants then completed a four session mindfulness meditation intervention where they were taught to focus on the changing sensations of the breath non-reactively After their respective intervention, these 15 participants received IV naloxone in session 6 After a two day washout period, 15 participants returned to the clinic and performed the saline infusion in session 7.
Non Mindfulness Meditation and Naloxone First
After providing informed consent, 18 participants participated in baseline testing. Three participants withdrew for scheduling issues after baseline. Fifteen participants then completed a four session non mindfulness meditation intervention where they were taught to independently take deep breaths. After their respective intervention, these participants received IV naloxone in session 6. However, a study nurse unintentionally instructed a patient that naloxone was to be infused and thus the participant was dismissed. After a two day washout period, 14 participants returned to the clinic and performed the saline infusion in session 7.

SECONDARY outcome

Timeframe: The Pain Catastrophizing Scale was administered at the baseline, post-intervention session 6 and session 7. Outcome measurements will compare change in Pain Catastrophizing Scale from baseline to session 7.

This is a 13-item questionnaire with 3 subscales assessing rumination, magnification, and helplessness in patients. A numeric value between 0 (not at all) and 4 (all the time) is provided in response to each statement. Scores on this assessment range from 0 to 52, with higher values reflecting more salient impacts of pain on one's day to day experience. The total range is from 0 - 52.

Timeframe: The Roland-Morris Disability Questionnaire was administered at the baseline, post-intervention session 6 and session 7. Outcome measurements will compare RMDQ from baseline to session 7.

The Roland-Morris Questionnaire (RMDQ) is a self-administered disability measure in which greater levels of disability are reflected by higher numbers on a 24-point scale. The RMDQ has been shown to yield reliable measurements, which are valid for inferring the level of disability, and to be sensitive to change over time for groups of patients with low back pain. Higher scores indicate greater disability. Total RMDQ scores are used before and after each intervention by group. The range of scores is from 0 - 24.

Timeframe: Administered at the baseline, post-intervention session 6 and post-intervention session 7. Outcome measurements will compare in BPI severity and interference from baseline to session 7.

Pain severity and interference: impact of pain on daily function, location of pain, pain medications and amount of pain relief in the past 24 hours or the past week. Higher scores indicate higher chronic pain. BPI severity and interference scales are used and collected before and after each intervention. Higher BPI severity indicate higher chronic pain severity. Higher BPI interference scores indicate higher chronic pain interference.The scoring scale for severity and interference range from 0 - 10, respectively.

Timeframe: Up to 8 weeks. Administered at visit 1, 6 and 7. Outcome measurements will compare SF-12 health survey from baseline to session 7.

This is a 12-item version of the SF-12 item Health Survey designed to assess general mental and physical functioning, and overall health-related quality of life. We used the physical functioning SF-12 scale and collected this information before and after each intervention and by group. The total range of scores is from 0 - 100. The minimum total score is 0 and the maximum score is 100. Higher scores indicate better functioning.

Participants will be taught that perceived sensory events are "momentary" and "fleeting" and require no further evaluation. Mindfulness: A well-validated brief meditation-based mental training regimen \[four sessions; 20 min/session\] is used to teach patients to independently practice closing their eyes and take a deep breath every few minutes. Naloxone: A 0.15 mg/kg bolus dose of naloxone (Naloxone hydrochloride, Amphastar Pharmaceuticals, Inc., Rancho Cucamonga, California) in 25ml normal saline will be administered over 10 minutes. The investigators also will administer a supplementary IV infusion dose of 0.1mg/kg/hour naloxone immediately after bolus infusion will cease till the end of the experiment. Saline: A 0.15 mg/kg bolus dose of saline in 25ml normal saline will be administered over 10 minutes. The investigators also will administer a supplementary IV infusion dose of 0.1mg/kg/hour saline immediately after bolus infusion will cease till the end of the experiment. Meditation: A well-validated brief meditation-based mental training regimen \[four sessions; 20 min/session\] is used to teach patients to independently practice closing their eyes and take a deep breath every few minutes.
