-
摘要:
目的 观察高频重复经颅磁刺激(rTMS)对脑外伤患者认知功能的影响。 方法 选取2021年1月至2022年1月昆明市延安医院收治的脑外伤患者160例作为研究对象,按照入院序号采用随机数表法随机分为治疗组、对照组各80例。对照组在常规药物治疗及认知训练的基础上给予rTMS假刺激,治疗组在常规药物治疗及认知训练的基础上给予rTMS真刺激,每日1次,每周治疗6d,共治疗4周。分别于治疗前、治疗4周后采用简易精神状态检查(mini-mental state examination,MMSE)、Rivermead行为记忆测验(rivermead behavioral memory test,RBMT)、蒙特利尔认知评估量表(montreal cognitive assessment,MoCA)对2组患者的认知功能进行评定。 结果 组内比较:治疗组MMSE评分指标(定向能力、记忆能力、回忆能力、计算能力)评分均较治疗前提高(P < 0.05),对照组MMSE评分指标(仅定向能力、即刻记忆能力)评分较治疗前提高(P < 0.05);治疗组RBMT评分指标(记姓、名,记被藏物、记约定、图片再认、即刻路径记忆、定向)评分均较治疗前提高(P < 0.05),对照组RBMT评分指标(仅记姓、名,记被藏物、图片再认、定向)评分较治疗前提高(P < 0.05);治疗组MoCA评分指标(记忆、语言、计算、定向)评分较治疗前提高(P < 0.05),对照组MoCA评分指标仅记忆、定向)评分较治疗前提高(P < 0.05);组间比较:治疗后,治疗组MMSE总分、RBMT总分、MoCA总分均较对照组提高(P < 0.05)。 结论 高频rTMS治疗能有效改善脑外伤患者的认知功能。 Abstract:Objective To observe the effects of rTMS on cognitive function in patients with traumatic brain injury. Methods A total of 160 patients with traumatic brain injury admitted to Yan’an Hospital of Kunming City from January 2021 to January 2022 were selected as the research objects and randomly divided according to the admission sequence number by random number table method. There were 80 cases in the treatment group and 80 cases in the control group. The control group was given sham rTMS stimulation on the basis of conventional drug treatment and cognitive training, while the treatment group was given true rTMS stimulation on the basis of conventional drug treatment and cognitive training, once a day, for a total of 4 weeks. Mini-Mental State Examination (Mini-mental State Examination) was performed before and 4 weeks after treatment. The cognitive function of the two groups was evaluated by MoCA, MMSE, RBMT. Results Intra-group comparison: the MMSE scores (orientation ability, memory ability, recall ability, calculation ability) of the treatment group were all improved compared with those before treatment (P < 0.05), while the MMSE scores (orientation ability, immediate memory ability) of the control group were only improved compared with those before treatment (P < 0.05). In the treatment group, the RBMT scores (remembering surname and given name, remembering artifact, remembering convention, picture recognition, immediate path memory, orientation) were all in- creased compared with those before treatment (P < 0.05), while in the control group, the RBMT scores (remembering surname and given name, remembering artifact, picture recognition, orientation) were only increased compared with those before treatment (P < 0.05). The MoCA scores (memory, language, calculation, orientation) in the treatment group were higher than those before treatment (P < 0.05), while the MoCA scores (memory, orientation) in the control group were only higher than those before treatment (P < 0.05). Comparison between groups: After treatment, the total scores of MMSE, RBMT and MoCA in the treatment group were higher than those in the control group (P < 0.05). Conclusion rTMS can effectively improve the cognitive function of patients with traumatic brain injury. -
