Purpose. Deficits in voluntary activation of the core stabilizing muscles are consistently observed in patients with chronic low back pain (CLBP); however, the underlying neural mechanism remains unclear. This cross-sectional study aimed at testing the hypothesis that the impaired voluntary activation of core stabilizing muscles is associated with structural and functional alterations in the basal ganglia, thalamus, and cortex in patients with CLBP. Methods.

Answering this question inevitably implies consideration of the technological level to which an alien civilization belongs. In this context, it is worth noting that in [1] the author has introduced a technological classification of advanced alien societies.
