Summary

Musculoskeletal pain represents the leading cause of disability worldwide. It has been traditionally attributed to peripheral mechanisms, but peripheral damage, inflammation, and psychological factors have failed to significantly account for the presence, absence, or severity of chronic musculoskeletal pain (CMP). Recent studies show that individuals with CMP exhibit dysfunctional pain modulation supporting a significant central nervous system (CNS) contribution. However, the CNS mechanisms underlying these changes in pain modulation are not currently known, nor is their relation to clinical pain progression. The proposed pilot examines brain circuits recently described in predicting the transition from acute to chronic pain, in predicting clinical and experimental pain changes as well as physical performance and mobility changes in older persons with musculoskeletal pain over a one year period. The findings will provide novel and important information regarding the mechanisms underlying aberrant pain processing and its functional consequences in older adults with musculoskeletal pain. The information learned can be subsequently used to target treatment and prevention strategies in future studies of older adults. The central hypothesis is that increased functional and structural connectivity of cortico-striatal regions will be significantly associated with baseline clinical and experimental pain and decreased physical function in persons with CMP and will account for more rapid clinical pain and disability progression over time.

Description

Chronic musculoskeletal pain (CMP) is the most common, non-malignant disabling condition that affects at least one in four older people. The most common painful musculoskeletal conditions among older adults are osteoarthritis, low back pain, fibromyalgia, chronic shoulder pain, knee pain, myofascial pain syndrome and previous fracture sites. Recent studies demonstrate generalized alterations of pain processing among older individuals with CMP. An improved understanding of the mechanisms underlying CMP-related changes in pain modulation will provide a basis for the development of targeted preventive and rehabilitative strategies. In light of evidence emphasizing plasticity of white matter connections, and the potential pain relieving effects of non-invasive brain stimulation interventions, it seems reasonable to identify these connections as potential targets for future treatment approaches. Given the expected growth of the older population, such strategies could have a monumental impact in reducing healthcare expenditures and improving the quality of life of older adults.
