背景：现有的标准失用量表很少，而且它们不能涵盖手势产生的所有领域和语义特征。因此，本研究的目的是评估新开发的上肢失用症测试(Tulia)的信度和效度，该测试内容全面，但实施起来仍然很短。方法：Tulia由48个项目组成，包括模仿和哑剧领域的非符号(无意义)、不传递性(交流)和传递性(工具相关)手势，分别对应于6个分测试。采用6分计分方法(0~5分)(评分范围0~240分)。对133例卒中患者、84例左半球损害(LHD)和49例右脑损害(RHD)患者以及50名健康受试者(HS)进行盲法评分。结果：临床测量结果显示，无论是在6个分测验的水平上，还是在单项水平上，评定者之间和评定者内(重测)的内部一致性、评定者间和评定者内(重测)的信度基本良好。标准效度采用文献验证假设的方法进行评价。结构效度与德伦齐测验高度相关(r=0.82)。结论：Tulia是一种可靠、有效的手势产出系统评价工具。该测试易于应用，因此对研究目的和临床实践都很有用。
Background:Only few standardized apraxia scales are available and they do not cover all domains and semantic features of gesture production. Therefore, the objective of the present study was to evaluate the reliability and validity of a newly developed test of upper limb apraxia (TULIA), which is comprehensive and still short to administer.Methods:The TULIA consists of 48 items including imitation and pantomime domain of non-symbolic (meaningless), intransitive (communicative) and transitive (tool related) gestures corresponding to 6 subtests. A 6-point scoring method (0-5) was used (score range 0-240). Performance was assessed by blinded raters based on videos in 133 stroke patients, 84 with left hemisphere damage (LHD) and 49 with right hemisphere damage (RHD), as well as 50 healthy subjects (HS).Results:The clinimetric findings demonstrated mostly good to excellent internal consistency, inter- and intra-rater (test-retest) reliability, both at the level of the six subtests and at individual item level. Criterion validity was evaluated by confirming hypotheses based on the literature. Construct validity was demonstrated by a high correlation (r = 0.82) with the De Renzi-test.Conclusion:These results show that the TULIA is both a reliable and valid test to systematically assess gesture production. The test can be easily applied and is therefore useful for both research purposes and clinical practice.
