目的:本研究的目的是探讨急性期认知功能损害与创伤性上肢损伤之间的关系。
方法:对三组进行了横断面观察性研究:神经损伤组,无神经损伤组,和对照组(未受伤的参与者)。人口特征(如年龄、性别,身体质量指数,和教育)和创伤特征(受伤后的持续时间,受伤的一面,疼痛,轻触感,手运动功能)被记录。使用Rey听觉和言语学习测试(RAVLT)和Stroop颜色和单词测试(SCWT,包括SIECT和SIECN),分别。
结果:该研究包括神经损伤组的43名参与者,该组30名参与者无神经损伤,和对照组的104名参与者。应用广义线性模型探讨了三组有影响者的认知功能差异。与其他两组相比,神经损伤组的RAVLT表现明显较差,与对照组相比,神经损伤组的SIECT评分较低。然而,3组间SIECN差异无统计学意义。此外,创伤特征对所有受伤参与者的RAVLT和SIECT均无显著影响(p>0.05).
结论:上肢外伤性神经损伤似乎与短期记忆和执行功能损害有关。而没有神经损伤的肌肉骨骼损伤显示没有认知障碍。因此,监测上肢神经损伤后的认知功能非常重要。
OBJECTIVE: The purpose of this study was to investigate the association between cognitive impairments and traumatic upper limb injuries of the acute phase.
METHODS: A cross-sectional observational study was conducted with three groups: a nerve-injury group, a without nerve injury group, and a control group (uninjured participants). Demographic characteristics (e.g. age, sex, body mass index, and education) and traumatic characteristics (duration since injury, injury side, pain, light touch sensation, hand motor function) were recorded. Short-term memory and executive functions were assessed using Rey Auditory and Verbal Learning Test (RAVLT) and Stroop Color and Word Test (SCWT, including SIECT and SIECN), respectively.
RESULTS: The study comprised 43 participants in the nerve-injury group, 30 participants in the group without nerve injury, and 104 participants in the control group. Generalized linear model was applied to explore the difference of cognitive functions among three groups with impactors. Significantly poorer performance on the RAVLT was observed in the nerve-injury group compared to the other two groups, and lower score of SIECT in nerve-injury group was lower compared to the control group. However, there was no significant difference of SIECN among three groups. In addition, traumatic characteristics did not significantly impact RAVLT and SIECT (p > 0.05) in all injured participants.
CONCLUSIONS: Traumatic nerve injury to the upper limb appears to be associated with both short-term memory and executive function impairment, whereas musculoskeletal injuries without nerve damage showed no cognitive impairment. Therefore, it is important to monitor cognitive function following upper limb nerve injuries.
