EXPERIENCE:

Mr. Heidebrecht’s experience in applied ergonomics and research spans nearly 15 years. His work has involved ergonomics, biomechanics, human factors, functional capacity and physiological assessments. Much of Mr. Heidebrecht’s work has dealt with ergonomic risk assessment and functional capacity evaluations; he has developed numerous ergonomic educational products and training modules including development of ergonomic analysis software. He has developed motion analysis equipment as well as designed return-to-work programs for injured employees by utilizing biomechanic equipment and functional tasks to test return-to-work status. Mr. Heidebrecht has developed and implemented ergonomic programs for government employees through employee training, physical demand documentation and functional capacity evaluations, while developing programs which have involved such tasks as customer service, mail processing, material handling, manufacturing, and office ergonomics.

Mr. Heidebrecht’s client base includes private industry as well as federal government clients. His work experience includes solutions for such industries as apparel manufacturing, public accounting, shipping/cargo, pharmaceuticals, appliance manufacturing, aerospace, insurance, and private hospitals. Federal government entities such as the United States Postal Service, OSHA, California Association of Rehab Providers (CARP), National Academy of Sciences, and American College of Sports Medicine have benefited from his services.

As a guest speaker, Mr. Heidebrecht has authored and/or presented numerous ergonomic and human factors topics throughout the United States, Australia and New Zealand. Topics have included workhab, ergonomic assessments of upper/lower body, certified ergonomic associate prep-course, functional motion, physical demand analysis and job matching, cumulative trauma disorders, kinetic and biomechanical analyses of lifting and lowering, and cost effective ergonomics.

His research in the fields of ergonomics and physiology has included analysis such as validity and reliability of wrist coder, personal attributes and cumulative trauma, kinetic analysis of lifting and lowering, tissue response to muscular strains, force plate foot strike, the stretch shortening cycle, and transcutaneous electrical nerve stimulation (TENS).
