Abstract: Objective To observe the effect of hyperbaric oxygen,rehabilitation training or acupuncture at Fengchi acupoint on pseudobulbar paralysis after stroke.Methods 90 patients were divided into group Ⅰ(A,B,C) or Ⅱ(A,B,C) randomly.Patients in all groups were given conventional therapy,while those in groups ⅠB and ⅡB were given hyperbaric oxygen,ⅠC and ⅡC were given swallowing training and group Ⅱ was given acupuncture at Fengchi acupoint additionally.They were assessed with Modified Kubota-Chiari's swallowing functional classification before and after treatment.Results In all groups except ⅠA,swallowing function scores improved after treatment significantly(P<0.05).The scores were different significantly between group Ⅰ and group Ⅱ after treatment(P<0.05).Except 3 d after treatment,the scores were different significantly between sub-group of group Ⅰ or group Ⅱon other time points(P<0.05).Conclusion The hyperbaric oxygen is more effective than conventional therapy on pseudobulbar paralysis,but less than swallowing training.Acupuncture at Fengchi acupoint can improve their efficacy.
