Pain, Brain and Mobility Study (PBAM)
16. februar 2016 oppdatert av: 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.

Detaljert beskrivelse
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.

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.

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.
Participants in both groups will have a Physical Performance test.
Participants in both groups will have an magnetic resonance imaging (MRI).
Participants in both groups will have blood samples taken.

No Chronic Pain Group
Participants that do not 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.
