The OCRA index method is presented elsewhere in this book. In that presentation, it was stated that the OCRA method was a concrete application of a Consensus Document produced by the Technical Group for Musculoskeletal Disorders of the International Ergonomics Association (IEA) (Colombini et al. 2001) and that the OCRA index can be, within definite limits, predictive of the risk of upper limbs ...

The OCRA method is the reference method chosen in ISO (ISO 11228-3) and CEN (EN 1005-5) standards regarding risk assessment and management of upper limbs repetitive movements and exertions. The method consists of two specific tools (OCRA index and OCRA checklist). In this paper special attention will be devoted to the procedures for the analysis of multiple repetitive tasks.When computing the O...

Upper limbs repetitive tasks are one of the main sources of risk for the workers of the manufacturing industries and the standards ISO 11228-3 and EN 1005-5 addressed this issue since 2007. EAWS (European Assembly Worksheet) is a 1st level ergonomic risk assessment method and it provides in its 4th section a score to measure the load level for the upper limbs based on a traffic light scheme. Ac...

background: up to today, the most complete risk assessment tool for repetitive movements of upper limbs has been the occupational repetitive actions (ocra) method. the index of the analysis is relatively accurate. several risk factors such as repeated motion, force, body condition, additional effective factors and return period can be useful for future preventive measures. the present study eva...

Several observational methods are available for ergonomists to evaluate the exposure to musculoskeletal disorder (MSD) risk factors associated with work. Those methods can be used to evaluate the impact of modifications done at a workstation on the exposure to risk factors. Three methods (QEC, OCRA and 4D Watbak) were used to assess the exposure to MSD risk factors before and after the implemen...

OCRA stands for Optimization-based Control for Robotics Applications. It consists of a set of platform-independent libraries which facilitates the development of optimizationbased controllers for articulated robots. Hierarchical, weighted, and hybrid control strategies can easily be implemented using these tools. The generic interfaces provided by OCRA allow different robots to use the exact sa...

The comparison between OCRA and the operating margin makes sense to decision maker. The operating margin (OM) shows them their ability to make and save more and more profit. The computation built in the study; help us to find the similar trend between efficiency from OCRA computation and Operating Margin from account statement. It resulted from the computation that the expected trend is obvious...

The Authors make a detailed analysis of the introduction of the OCRA Methodology in Brazil that started in August 2008 with the launching of the "OCRA Book" translated to Portuguese. They evaluate the importance of the assessment of the exposure of the upper limbs to the risk due to repetitive movements and efforts, according to the national and international legislation, demonstrating the inte...

Tomatoes are the most common crop in Italy. The production cycle requires operations in the field and factory that can cause musculoskeletal disorders due to the repetitive movements of the upper limbs of the workers employed in the sorting phase. This research aims to evaluate these risks using the OCRA (occupational repetitive actions) index method This method is based firstly on the calculat...
