"Contents: an introduction to ergonomics and the aim of this handbook. Musculoskeletal diseases due to biomechanical overload. Establishing the presence of risk and the subsequent means of intervention. The general model of exposure analysis: relevant definitions and their interaction with job analysis using the methods-time measurement (MTM) system. Work organization analysis: task analysis, cycle time and rest periods. Analysis of repetitiveness and frequency of action. Analysis and quantification of force using the Borg Scale. Analysis and evaluation of working postures. Definition and quantification of additional risk factors. Analysis and evaluation of recovery periods. Proposed concise index for the assessment of exposure to repetitive movements of the upper limbs (OCRA Index). A check-list model for the quick evaluation of risk exposure (OCRA Index). European technical standards in the ergonomics. Guidelines for designing jobs featuring repetitive tasks. A longitudinal study of workers with WMSDs after returning to a redesigned workstation: criteria for the return of workers to the workforce."
