Abstract: The psychological mechanisms underlying low back pain (LBP) are multifaceted and intricate. In this study, we delved into the power spectrum and irregularity degree performance of electroencephalogram (EEG) signals in patients with LBP and healthy groups. Our aim was to unveil a potential psychological activity pattern in the brain associated with subjective pain in patients with LBP. We examined the frequency bands of ongoing EEG activity in 19 patients suffering from LBP caused by neurological vertebral disorders of reflex origin, comparing them to a control group of nineteen subjects. Energy ratio and sample entropy were utilized to evaluate the complexity changes in EEG signals in the brain. The results showed the significant differences in brain activation between the LBP and control groups in the studied scenarios. During dynamic steady-state, the results displayed significant differences in the energy ratio of delta, theta, alpha, and beta bands in most EEG leads in both groups. Similarly, the irregularity degree of EEG signals demonstrated that the sample entropy of the LBP group was significantly greater than that in subjects of the healthy control group during dynamic steady-state. The significant difference between BLP and health groups suggest that these features based on surface electromyography (sEMG) holds promise as a viable alternative to conventional methods. Therefore, this study could serve as an inspiration for designing tailored programs aimed at ensuring the effective rehabilitation of LBP patients. Moreover, LBP exhibited numerous variations in the evaluated parameters, reflecting changes in energy ratio and their respective sample entropy values when compared with the healthy control group during static and dynamic steady-state exercise. These changes were accompanied by widespread oscillatory changes in scalp EEG. These findings further emphasize the complex relationship between dynamic steady-state exercise and psychological performance in LBP. The alterations observed in EEG during dynamic steady-state were modulated by subjective pain and psychological activity.
