Abstract:
Objective:To explore the remodeling of brain function 2 years after anterior cruciate ligament reconstruction (ACLR) and its relationship with functioning and behavior.Methods:Forty-eight volunteers who had received ACLR from the same surgeon were divided into a coping and a non-coping group, each of 17. Another 14 health volunteers formed the control group. Resting-state functional magnetic resonance imaging was used to record blood oxygen level-dependent signals from the members of all three groups in the 0.01 to 0.08Hz band. One-way analysis of variance was applied to the differences in low frequency amplitude (ALFF) observed.Results:The results of multiple comparisons with Gaussian random field theory correction showed that the differences in bilateral putamen ALFF values among the three groups were statistically significant. The signals from the right cerebellar area 8 and the bilateral putamen were significantly stronger among the non-coping group on average. Pearson correlation analysis showed that the ALFF values from the right cerebellar 8 region were positively and significantly more correlated with the symmetry of a subject′s Y balance function test results in the coping group compared with the non-coping group.Conclusions:Subcortical brain function remodeling occurs in ACLR patients returning to exercise after surgery, and a Y-balance function test can indirectly reflect such remodeling. That can provide a basis for designing programs for rehabilitating advanced brain functions.
