DESCRIPTION: Dr. Nancy A. Baker, ScD, the candidate for this Special Emphasis Research Career Award, is an Assistant Professor in the School of Health and Rehabilitation Sciences (SHRS) at the University of Pittsburgh. Her immediate career goals are to develop her skills as an independent researcher and improve her expertise in biomechanical theory, test development, epidemiology, and statistical analysis through mentored research and coursework. She plans to apply for an R01 award with the data acquired during this study. Her long term career goal is to develop a research program which will evaluate clinical interventions for preventing and remediating musculoskeletal disorders of the upper extremity (MSD-UE) in computer users. This proposed three-year study will be divided into two phases. Phase I will be devoted to developing and refining an instrument, the Pre-PeCKS, into a valid and reliable data gathering observational tool. /n Phase 1I the Pre-PeCKS will be used to develop a predictive model that can discriminate between those with and without MSD-UE. The model developed will be used to select the construction and weighting of the subscales of the final instrument, the PECKS. The specific aim of Phase I is to evaluate the inter- and intra- rater reliability and the concurrent criterion-related validity of the Pre-PeCKS; the specific aim of Phase II is to use information gathered using the Pre-PeCKS to develop a diagnostic instrument that can identify those with and without MSD-UE. In Phase I, 50 subjects will be digitally recorded while typing while at the same time the kinematics of their hands will be recorded using a VICON TM motion analysis system and a keyboard force plate. The video of the typing performance will be rated by independent raters using the Pre-PeCKS and reliability statistics will be calculated. Concurrent validity will be obtained by comparing the results of the VICON TM with the results of the Pre-PECKS. In Phase 11, 20 typists with MSD-UE and 20 typists without MSD-UE will be rated using the Pre-PeCKS. Variables from the Pre-PeCKS along with other variables of interest will be used to build models that can discriminate between those with and without MSD-UE. The best model will be used to assign weights to Pre-PeCKS parameters and to develop how subscores will be combined to best identify those with MSD-UE. This information will be integrated into the final tool, the PECKS. The PECKS can then be used to identify an individual who have keyboarding...styles that have been associated with MSD-UE.

描述：匹兹堡大学卫生与康复科学学院（SHRS）的助理教授Nancy A. Baker博士，SCD，SCD，SCD候选人。她的直接职业目标是通过指导的研究和课程来发展她作为独立研究人员的技能，并提高她在生物力学理论，测试发展，流行病学和统计分析方面的专业知识。她计划在本研究中申请R01奖励。她的长期职业目标是制定一项研究计划，该计划将评估计算机用户中上肢（MSD-EU）的预防和修复肌肉骨骼疾病的临床干预措施。 这项拟议的三年研究将分为两个阶段。第一阶段将致力于开发和完善仪器，即预挑选，成为有效且可靠的数据收集观测工具。 /n阶段1i预赛将用于开发一个可以区分有MSD-EU的人的预测模型。开发的模型将用于选择最终仪器（啄木鸟）子量表的构造和加权。第一阶段的具体目的是评估挑选前的范围内和内部可靠性以及与标准相关的有效性；第二阶段的具体目的是使用使用预捕捞来收集的信息来开发可以识别有或没有MSD-EU的诊断工具。在第一阶段，将使用VICON TM运动分析系统和键盘力板记录50名受试者，同时将记录50名受试者。打字性能的视频将由独立评估者使用预挑选者进行评级，并将计算可靠性统计。并发有效性将通过将Vicon TM的结果与挑选的结果进行比较。在第11阶段，将使用预挑选的20名具有MSD-EU的打字员和20位没有MSD-EU的打字员进行评分。挑选前的变量以及其他感兴趣的变量将用于构建可以区分有和没有MSD-EU的模型。最佳模型将用于将权重分配给预挑选参数，并开发如何组合子尺寸以最好地识别使用MSD-EU的人。此信息将集成到最终工具，即啄。然后，可以使用佩克来识别具有键盘的个人...与MSD-EU相关的样式。
