Abstract Rehabilitation assessment can help clinicians to understand patients rehabilitation situation, formulate a reasonable rehabilitation training plan, and improve the efficiency of rehabilitation treatment. However, the traditional rehabilitation evaluation methods cannot timely reflect and dynamically evaluate the rehabilitation situation, which would reduce the efficiency of the rehabilitation treatment of stroke patients. In order to solve the above problems, quantitative electroencephalogram (qEEG), an objective rehabilitation evaluation method, was introduced in this study, which has the advantages of convenient collection and rapid feedback, and can quickly reflect the rehabilitation situation of stroke patients and make up for the shortcomings of traditional rehabilitation assessment methods. In this study, 28 patients with chronic ischemic stroke were enrolled. The EEG data of the patients were collected and thepower ratio index, Brain symmetry index andphase synchrony index were calculated, and Spelman correlation coefficient was used to analyze the correlation between the above-mentioned qEEG and the modified barthel index and the upper extremity motor section of the Fugl-Meyer motor assessment (FMA). The results showed that there was a significant positive correlation between the modified barthel index and the IH-PSI in the β band of the global channel (ρ=0.70 P=0.000 2). The correlation between the modified barthel index and the IH-PSI in the β band of the global channel was the strongest compared with the other qEEG, the correlation coefficient was ρ = 0.70, and P=0.000 2<0.01, which was statistically significant. The correlation between the upper extremity motor section of the FMA and the C3FC3C4FC4-PSI in the β band using four channels of C3, C4, FC3, FC4 was the strongest compared with the other qEEG, the correlation coefficient was ρ=0.71, and P=0.000 09<0.01, which was statistically significant. In summary, the use of the IH-PSI in the β band of the global channel combined with the modified barthel index, the use of the C3FC3C4FC4-PSI in the β band using four channels of C3, C4, FC3, FC4 combined with the upper extremity motor section of the FMA was expected to achieve dynamic assessment of patients with chronic ischemic stroke, and improved the efficiency of rehabilitation treatment for stroke patients.
