The Clinical Value Of Apparatus ZM2.1 For Diagnosis And Treatment Of Language Disorders In Diagnosing And Treating Aphasic Patients

Purpose1. To understand the normal fluctuating ranges of the ZM2.1 Diagnosis System functional subitems by examining the normal Chinese adults.2. To observe the stability and validity of the ZM2.1 Diagnosis System by examining aphasic patients.3. To validate the efficacy of the ZM2.1 Rehabilitation System by examining aphasic patients before and after therapy with ZM2.1. Methods1 . Two hundred and two normal Chinese adults were examined with ZM2.1 in multicenter, through analyzing the variance of occupation, sex, handedness, age, educational level to find out any influence on the ZM2.1 functional subitems.2. Forty-seven aphasic patients were selected in multicenter as the case group and 47 normal adults with similar backgrounds as the control group, the difference of scores of the ZM2.1 functional subitems werecompared between two groups. Among them 20 cases were retested after one week, the artificial assessments of marks were given by two investigators separately, then underwent correlation analysis and consistent tests.3. Forty-seven aphasic patients were examined both the Aphasia Battery of Chinese and ZM2.1 in random order, then the key functional subitems were analysed relevantly.4. Among 47 aphasic patients, eleven cases were examined with the ZM2.1 Diagnosis System before and after therapy by using the ZM2.1 Rehabilitation System, the difference of scores of the ZM2.1 functional subitems were compared before and after therapy.Results1. The effects of age and educational level on the ZM2.1 functional subitems were observed in statistical level.2. Significant difference of scores of the ZM2.1 functional subitems between normal group and aphasia group were found. The ZM2.1 Diagnosis System could show aphasia severity.3. For the aphasia group, the reliability of the retest of 20 aphasic patients as well as the consistency of the different examiners was good. The correlation of ABC and ZM2.1 result was good. The ZM2.1 Diagnosis System could screen the aphasia type according to the scores of the functional subitems. The ZM2.1 Diagnosis System has goodsensitiveity and specificity. Conclusions1. The norm of the functional subitems of the ZM2.1 Diagnosis System should consider the age and education level.2. The ZM 2.1 Diagnosis System can differentiate the abnormal language from normal language and screen the type of aphasia effectively.3. The ZM 2.1 Diagnosis System has good stability and validity, has good sensitiveity and specificity, it fulfils the essential requirements of aphasia battery and standardizing psychological test.4. The ZM 2.1 Rehabilitation System has good curative in recovery of aphasic patients...
