Pain, Brain and Mobility Study (PBAM)

February 16, 2016 updated by: University of Florida

Central and Peripheral Mechanisms Predicting Clinical Pain and Physical Performance in Older Adults

The aim of this project will be to document the central and peripheral mechanisms, which may predict clinical pain characteristics and associated physical performance in older adults. Although chronic pain is common among older adults, there is limited understanding on the processing of pain and the mechanisms by which it affects physical function in these individuals. The first aim of this study will be to examine predictors of clinical pain in older adults. These will include a comprehensive somatosensory assessment battery including mechanical and thermal detection and pain thresholds in older adults with and without chronic pain. The investigators will also assess basal cognitive and physical function to determine their associations with chronic pain. Finally, brain structure and function will be assessed in these older adults with and without pain.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Withdrawn

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The purpose of this research study is to learn more about how pain in older individuals changes the brain and impacts a person's mobility and function. Pain is influenced by biology (like hormones), psychology (thoughts and feelings), and habits (like sleep or exercise) that may make older adults more likely to have higher or lower levels of pain.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

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.

Design Details

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Chronic Pain Group
Participants that experience chronic pain will have the following procedures performed: A sensory assessment called quantitative sensory testing or QST that will assess in detail your ability to feel sensations due to touch, vibration, and changes in temperature on the skin; Pressure sense will be produced by a device that will be pressed against the skin for several seconds; Pinprick pressure will be applied to determine if the pain can be rated; a Physical Performance test will be performed; and an magnetic resonance imaging (MRI) will be done. In addition, blood sample, blood pressure, heart rate, and skin temperature will be taken during the procedures.
Procedure: Quantitative Sensory Testing (QST)
Participants in both groups will have a sensory assessment called quantitative sensory testing or QST that will assess in detail your ability to feel sensations due to touch, vibration, and changes in temperature on the skin.
Procedure: Physical Performance

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
Brain magnetic resonance imaging (MRI)
Time Frame: Baseline and 12 months later
Differences in the MRI on the brain scans of participants with greater pain severity
Baseline and 12 months later

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
Inflammatory markers in blood samples

To test the markers of pro-inflammatory (IL-1b, tumor necrosis factor (TNF-a)) and anti-inflammatory (IL-4, IL-10) with participants more sensitive to pain than the ones less sensitive to pain.

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
