Abstract
Trunk control involves integration of sensorimotor information in the brain. Individuals with chronic low back pain (cLBP) have impaired trunk control and show differences in brain structure and function in sensorimotor areas compared with healthy controls (HC).
Introduction
Trunk control requires integrating visual, proprioceptive, and vestibular sensory information [1] and is historically recognized to involve spinal, cerebellar, and subcortical structures [2, 3]. More recent neuroimaging and electroencephalography data have unequivocally demonstrated trunk control requires the involvement of primary and secondary cortical sensorimotor brain regions [4–15].
Materials and methods
A sample of 32 participants with cLBP and 35 demographically similar [age (±5 years), sex, and BMI (±2 kg/m2) matched] HC were recruited from the local community (Table 1).
Results
No between-group differences were observed for sex, age, or BMI. Group differences were observed for measures of depression, pain catastrophizing, and state and trait anxiety, where the cLBP group demonstrated higher scores on these measures (Table 1).
Discussion
To the authors’ knowledge, this is the first study to use dMRI to provide insight into the relationships between white matter structure and seated trunk control in cLBP. We compared seated trunk control and cortical sensorimotor WM between persons with cLBP and matched HC.
Conclusion
Persons with cLBP demonstrate worse trunk control performance compared with HC. Although no differences in cortical sensorimotor white matter were observed between groups, cortical sensorimotor microstructure and anatomical connectivity.
