Brief Summary

This study will develop and refine an observational assessment tool called the Personal Computer Keyboard Style (PeCKS). When completed this assessment tool will provide researchers and clinicians with a valid and reliable method to describe computer keyboarding postures and kinematics. The proposed 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. In Phase II 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. Phase I - PeCKS psychometrics - reliability and validity Specific Aim 1: To evaluate inter- and intra-rater reliability and the concurrent criterion-related validity of the Pre-PeCKS. H.1.1 The Pre-PeCKS will demonstrate acceptable reliability for the following tests: H.1.1a. Intra-rater reliability (stability within one rater) H.1.1b. Inter-rater reliability (stability across raters) H.1.1c. Test of internal consistency (Cronbach's alpha) (stability across items) H.1.2 The Pre-PeCKS will demonstrate good concurrent criterion-related validity - Parameters selected by raters using the Pre-PeCKS will significantly correlate with biomechanical measures (VICON™ motion recording and analysis system and force plate): H.1.2.a. Angles and displacements identified by raters using the Pre-PeCKS will correlate with angles and displacements measured by the VICON™ motion recording and analysis system; H.1.2.b. Number of times spent performing actions as specified by raters using the Pre-PeCKS will correlate with number of times measured by a VICON™ motion recording and analysis system; H.1.2.c. Level of forceful keying as specified by raters using the Pre-PeCKS will correlate with levels of forceful keying measured with a force plate under the keyboard. Phase II - PeCKS psychometrics - diagnostic tool development Specific Aim 2: To use information gathered using the Pre-PeCKS to develop a diagnostic instrument that can identify those with and without MSD-UE. The major hypothesis related to Specific Aim 2 is: H.2.1. Using information gathered with the Pre-PeCKS and knowing the disease outcome of the subjects, predictive models can be developed that discriminate between those who do and do not have MSD-UE.
