Motor deficit duration was the time from outpatient diagnosis to inpatient functional MRI scan.
KPS, Karnofsky Performance Scale.
*Values are the mean ± SEM. Student’s t-test was used to compare the differences of the tumor volume and the Karnofsky Performance Scale scores between the deficit and non-deficit groups. One-way ANOVA was used to compare the differences of age and education period between the deficit, non-deficit, and healthy groups. Fisher’s test was used to compare the differences of gender and tumor grade between the deficit and non-deficit groups. The deficit group comprised patients with preoperative motor deficit; the non-deficit group was composed of patients without preoperative motor deficit.
