Comparing Yoga Nidra, Yoga, and Control Condition on Pain in Individuals With Chronic Low Back Pain
What this study is about
Individuals with chronic low back pain will undergo a yoga, yoga nidra, and control condition on separate visits. Each visit, before and after the intervention, participants with rate their pain in response to heat stimuli, a sit to stand task, and questionnaires.

Individuals with chronic low back pain will undergo a yoga, yoga nidra, and control condition on separate visits. Each visit, before and after the intervention, participants with rate their pain in response to heat stimuli, a sit to stand task, and questionnaires.
Interventions
OTHER
Yoga
Participants will complete a series of yoga poses.
OTHER
Yoga Nidra
Participants will complete yoga nidra, a guided meditation.
OTHER
Control Condition
Participants will listen to a story.
Primary outcome measures
Heat Pain Threshold
Time frame: through study completion, typically 2 weeks
Participants will undergo heat pain threshold. A thermode will be applied to the low back with temperature increasing at 1 degree Celsius per second. Participants will report when the sensation changes from heat to pain and the temperature recorded.
Temporal Summation
Time frame: through study completion, typically 2 weeks
Participants will apply thermode to the bottom of the foot and rate their pain in response to 10 heat pulses peaking at 49 degrees Celsius.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
