Low back pain (LBP) is a condition that affects a majority of the US population and is responsible for a significant proportion of health care costs and utilization. Lumbar spine muscle is compromised in LBP, and do, and do not, respond to exercise based physical therapy program depending on measurements representing activation capacity of lumbar muscle. Here, we will characterize the neurological and muscle specific features that may contribute to limited activation in an attempt to identify sources of resistance to recovery in patients with chronic disc injury and identify precision rehabilitation approaches for this complex population of individuals.
Low back pain (LBP) is a complex condition that affects 65-85% of the population, and is the leading musculoskeletal condition contributing to disability in the United States. Disc injury is the most common injury and 75% of individuals undergoing surgical and rehabilitative interventions for this condition experience suboptimal or poor outcomes. These patients demonstrate disability and deficits in functional capacity, and paraspinal muscles in these individuals have been shown to be altered in volume, composition, and mechanical properties. These maladaptive changes influence the ability for…
