title: Impact of chronic musculoskeletal pain on objectively measured daily physical activity: a review of current findings.
abstract: SUMMARY Chronic pain affects a wide range of outcomes that are typically assessed using self-reported methodologies, which are susceptible to recall biases, current mood and pain intensity. Physical activity (PA) is an important component of the pain experience that can be objectively assessed with accelerometers, which are small, lightweight devices that measure the duration, frequency and intensity of PA over time. Accelerometry provides opportunities to compare actual and perceived PA, to design individually customized treatments, to monitor treatment progress, and to evaluate treatment efficacy. Thus, this technology can provide a more refined understanding of the relationships among symptoms, perceptions, mood, environmental circumstances and PA. The current paper examines patterns of PA in chronic musculoskeletal pain conditions and identifies potential clinical applications for accelerometry.
