Abstract:
Objective:To explore the differences in balance ability and brain activation level between the cerebral palsy(CP)adolescents and the typically developing(TD)adolescents.Method:Eight adolescents with CP or TD were recruited in this study.The center of pressure(COP)was measured using an AMTI three-dimensional force platform to assess the standing balance under perturbation or non-perturbation condition.Brain activation level was also measured using the fNIRS device to collect the oxy-genated hemoglobin concentrations(ΔHbO2)in the supplementary motor area(SMA),precental gyrus(PreCG),postcentral gyrus(PoCG)and superior parietal lobule(SPL).Result:①Balance ability indicators:During the perturbation condition,DeltaAP,RMS,RMSAP,SPAP in the CP group were significantly greater than those in the control group.In the CP group,DeltaAP,DeltaML,RMS,RMSAP,SPAP during the perturbation condition were significantly greater than those during the non-pertur-bation condition.②Brain activation level indicators:During the perturbation conditions,the ΔHbO2 of SMA in the CP group were significantly greater than those in the control group.In the CP group,the ΔHbO2 of SMA,PreCG,PoCG during the perturbation condition were significantly greater than those during the non-per-turbation condition.Conclusion:Compared to the TD adolescents,the CP adolescents had poorer balance in the anterior-posterior direction and higher level of SMA activation in the external perturbation condition.Under the external perturba-tion condition,the balance ability decreased in the anterior-posterior direction,while the activation level of SMA,PreCG and PoCG increased in the adolescents with CP.
