Analysis of Amplitude of Low Frequency Fluctuation (ALFF) alterations and its relationship to clinical metrics in Degenerative Cervical Myelopathy (DCM) patients. a The increased ALFF in DCM patients. lMCC: left Middle Cingulate Cortex; lSFG: left Superior Frontal Gyrus; b The decreased ALFF in DCM patients. rM1: right precentral gyrus; lV1: left calcarine gyrus. c The heat map for illustrating the correlation coefficients between brain alterations and clinical metrics in DCM patients. PT: Pain Threshold; PVAQ: Pain Vigilance and Awareness Questionnaire; JOA: Japanese Orthopedic Association (JOA). d The scatter plot for association between postoperative pain intensity and ALFF, between PT and ALFF within MCC in DCM patients
