About
This project aims to elucidate neural correlates of proprioceptive deficits in patients with recurrent non-specific low back pain, by studying whether brain activation patterns during the processing of proprioceptive signals from the ankle muscles and lower back muscles are altered compared to healthy control subjects.
Full description
Low back pain is a highly prevalent health condition, with a reported lifetime prevalence of up to 84% worldwide. Currently, it induces more disability than any other health condition, such as depression, diabetes, chronic obstructive pulmonary disease or other musculoskeletal disorders. Approximately 85% of all low back pain complaints are non-specific, meaning that the pain cannot be attributed to a recognizable specific pathology such as an infection or vertebral fracture. While many patients with low back pain recover within a month, a large number of patients report a recurrence within one year. Current treatment interventions often remain unsuccessful, which highlights the current lack of knowledge on the underlying mechanisms of non-specific low back pain.
Postural control deficits have been identified as a key factor in the development and recurrence of non-specific low back pain. To achieve optimal postural control, the central nervous system needs to process, integrate and weigh proprioceptive signals from different body regions (e.g. ankle muscles and lower back muscles) with vestibular and visual inputs. Several studies have shown that patients with non-specific low back pain have a decreased ability to optimally weigh proprioceptive signals during standing, which leads to reduced postural robustness compared to pain-free individuals. More specifically, patients with low back pain dominantly rely more on proprioceptive signals from the ankle muscles and are not able to up-weigh proprioceptive signals from the lower back muscles when needed. This might be due to an impaired central processing of proprioceptive signals. However, up to now no studies have investigated central proprioceptive processing in patients with recurrent non-specific low back pain.
Therefore, this project aims to elucidate whether patients with recurrent non-specific low back pain showed altered brain activation patterns during the processing of proprioceptive signals from the ankle muscles and lower back muscles compared to healthy controls, by applying local muscle vibration during functional magnetic resonance imaging (fMRI).
