Brief Summary

Background: Researchers want to better understand pain by studying people with and without different kinds of pain. To do this, researchers will expose people to pleasant and unpleasant sensations. They will ask them questions about their pain. Researchers also want to see if these people are eligible for other research studies at the National Center for Complementary and Integrative Health. Objectives: To study the experience of pain. Also to find people eligible to join other NIH studies. Eligibility: People 12 years and older with and without pain disorders. Design: Participants will be screened by phone. Participants will have one required visit lasting about 2 hours. This may include:

  • Medical history
  • Physical exam
  • Questionnaires about themselves and their pain experience
  • Blood and urine tests
  • MRI: They will lie on a table that slides into a cylinder. They will feel different sensations while completing tasks on a computer. This lasts 15 minutes to 2 hours.
  • Quantitative sensory testing: They will be exposed to different pictures, sounds, tastes, and smells. They will also be exposed to pleasant and unpleasant sensations. These could include:
  • Burning, itching, or cold sensations
  • Pinpricks
  • Pressure and pinches
  • Electrocardiogram: Stickers on the chest record heart activity.
  • Straps placed around the chest to measure breathing.
  • Small sensors on the fingers or palms to measure pulse and sweating. Participants may have up to 12 other outpatient study visits. Participants may be recorded at the visits.

Outcome Measures

Primary Outcomes (1)

  • To enable for the deep, broad, and targeted phenotyping of individuals, in particular those with rare and unusual pain disorders.

    Data are to be collected via medical history, physical examinations, questionnaires, laboratory samples and MRI imaging.

    36 months

Secondary Outcomes (1)

  • To facilitate obtaining information relevant to determining potential eligibility in IRB-approved NIH protocols, in particular those of the Clinical Investigations Branch of NCCIH.

    36 months

Study Arms (1)

Persons, with or without pain disorders

Adults and adolescents with or without pain disorders.

Sampling MethodNon-Probability Sample
Study Population

Participants with or without pain disorders.

You may qualify if:

  • Are \>= 12 years of age

You may not qualify if:

  • Have difficulties with communication that make subjective pain assessment impossible or unreliable.
  • Have acute medical or psychiatric health issues that create additional and substantial adverse risks related to study procedures. Medical examples are the acute complications of medical disease, such as asymptomatic hypertensive urgency, diabetic ketoacidosis, symptomatic hyperthyroidism, and unstable angina. Psychiatric examples are the acute complications of psychiatric disease, such as acute mania, paranoid delusions, or having acute panic attacks.
  • Are participating in other ongoing research protocols such that phenotypic measurements would interfere with the conduct of an ongoing protocols or the receipt of a research treatment would influence the phenotypic measurements.
  • Employees or staff that work at NCCIH.
  • Pregnant women
