3D Static Strength Prediction Program

Technology #0269

The 3D Static Strength Prediction Program™ (3D SSPP) is an effective way to analyze the biomechanics and safety of manual materials handling. The software allows the user to predict static strength requirements for common manual tasks like lifts, presses, pushes, and pulls. 

The information that the Static Strength Prediction Program provides can be used to evaluate the physical demands of a job and to prompt a redesign of the job to reduce the risk of repetitive strain injury. The software program also provides information that can help shape workplace designs and redesigns prior to construction or renovation.

Workplace injuries have a substantial impact on a company’s bottom line. The National Institute for Occupational Safety and Health (NIOSH) reports that back disorders affect more than 600,000 individuals each year at an annual cost of approximately $50 billion. The 3D Static Strength Prediction Program can help create a safer work environment and reduce the rate of injury and the costs associated with OT or physical therapy.

The manual materials handling analysis programs (including the Static Strength Prediction Program) developed by the Center for Ergonomics at the University of Michigan College of Engineering are used in over 2,000 sites in the U.S. and around the world.

Static Strength Prediction Technology Offers Human Factor Analysis with 3D Biomechanical Figures

The program’s output consists of ten reports that include predicted low-back compression forces, the percentage of the population that have the strength to perform a prescribed job, and data comparisons to the National Institute of Occupational Safety and Health guidelines. The user can analyze torso twists and bends and make complex hand force entries. The software has an automatic posture generation feature and 3D human graphic illustrations.

Users can download the current version from the 3D Static Strength Prediction Program website. The software has been tested successfully on Windows XP, VISTA, and Windows 7 systems. Users have fourteen days after installation to evaluate the software for no charge.

The Center for Occupational Health and Safety Engineering at the University of Michigan offers workshops on using the software and open enrollment courses. The University will arrange special courses for groups on campus or on site. The college continues to improve and update the Static Strength Prediction Program to make it more functional and easier to use.

While the program should not be used as the sole determinant of worker strength or job designs, the program offers an effective aid in evaluating the physical demands of a prescribed job.
