| 1 | 腕管综合征主要症状体征敏感性与特异性的比较显示文摘目的 比较腕管综合征 (carpaltunnelsyndrome ,CTS)主要症状、体征的敏感性与特异性。方法 对 10 1例 ( 162只手 )进行症状严重程度与功能状况的询问 ,感觉、运动功能的检查 ;其中 62只手在术后 6周再次测定。结果 162只患手中 15 8只具有典型症状 ( 98% )。Phalen征、前臂正中神经加压征、Semmes Weinstein单丝纤维测试阳性率分别为 98%、96%、82 %。 87%的患手出现肌力下降 ,拇短展肌肌力测定 (定量法 )结果显示 ,与徒手法相比 ,不同性别间、术前与术后的差异均具非常显著意义 (P <0 .0 1)。结论 典型症状、Phalen征、前臂正中神经加压征、拇短展肌肌力变化的敏感性与特异性最高 ,拇短展肌肌力定量法测定是判断腕管综合征严重程度、评定疗效的一个良好的客观指标。 | 刘璠 Lois Carlson H.Kirk Watson | 2004 | 中华手外科杂志2004，20，3： | 8 |
| 2 | Reliability Study on Quantitative Detection of Extensor Digi- torum Brevis Strength with Needle Electromyography and Nerve Conduction显示文摘Objective To study the objectivity and reliability of needle electromyography and nerve conduction for detection of musculus extensor digitorum brevis strength, which may provide a basis for establishing a quantitative detection of muscle strength in forensic clinical study. Methods Forty-four healthy people were enrolled as the subjects, and during toe dorsiflexion, the following items including needle electromyography indexes, motor unit potential(MUP) amplitude, MUP count, recruitment reaction type, and nerve conduction detection indexes, compound muscle action potential(CMAP) amplitude, CMAP latent period and motor nerve conduction velocity(MNCV), were simultaneously detected under the cooperation and disguise condition. Results Under the cooperation condition, regardless of the same operator or different operators, there were good test-retest reliabilities in MUP amplitude, CMAP amplitude, CMAP latent period and MNCV, while there were normal test-retest reliabilities in MUP count and recruitment reaction type and the repeatability of the same operator was slightly better than the repeatability between different operators. Under the disguise condition, test-retest reliabilities of MUP amplitude, CMAP amplitude, CMAP latent period and MNCV were relatively high, while test-retest reliabilities of MUP count and recruitment reaction type were relatively low. Conclusion There are good test-retest reliabilities in MUP amplitude, CMAP amplitude, CMAP latent period and MNCV, which can be conducive to comparison between different operators and results at various times; MUP count and recruitment reaction type, which can be easily affected by subjectivity of operators and examinees, can be used to differentiate whether an examinee disguises or not. The indexes used to objectively judge muscle strength remain to be further investigated. | GAO Dong XIA Qing RAN Dan TIAN Dong ZHU Guang-you FAN Li-hua | 2013 | 法医学杂志2013，29，6： | 4 |
| 3 | 屈肘肌力定量检测及Micro FET2肌力测试仪信度研究显示文摘目的探究屈肘肌群肌力的规范化定量检测方法及Micro FET2肌力测试仪的信度。方法将62例健康受试者分为组A(男22例,女30例)和组B(男5例,女5例),取仰卧位,使用Ober可调式肘关节固定支具将组A受试者肘关节分别固定于6种体位(前臂旋后或中立并屈肘),将组B受试者分别固定于前臂旋后的3种体位,使用Micro FET2肌力测试仪分别测量左、右两侧定量肌力。组A全部由操作者a测量;组B由操作者a和b各测量一次,后由操作者a重复测量一次,研究组内及组间信度。各次测量间隔7~10 d。结果(1)相同屈肘角度时,前臂旋后90°时屈肘肌力大于前臂中立位,且差异具有统计学意义(P<0.05);前臂相同体位下,屈肘30°、80°、100°时的肌力逐步增大;(2)组A中男性、女性均在前臂旋后90°屈肘100°时达最大屈肘肌力;(3)操作者组内及操作者组间信度分析ICC值均>0.75。结论(1)屈肘肌力大小与肢体体位有关,前臂旋后90°并屈肘100°时屈肘肌力最大;(2)Micro FET2肌力测试仪具有良好的信度,结合规范化检测方法,在涉及肌力评价的法医临床学鉴定中具有良好的应用前景。 | 卓佩佩 夏晴 高东 陈捷敏 冉聃 夏文涛 | 2019 | 中国司法鉴定2019，0，6： | 1 |
