3. ASEP Ergonomic support development Fall 2002 The Need... “Scientific evidence shows that musculoskeletal disorders of the lower back and upper extremities can be attributed to particular jobs and working conditions – including heavy lifting, repetitive and forceful motions, and stressful work environments…but the problem can be reduced with well-designed intervention programs.” National Academy of Sciences Report (1/18/2001) FY 99: 43% of all disabling workplace injuries and illnesses (nation-wide) are associated with ergonomics and at a financial cost of $16.8 billion. [Liberty Mutual Workplace Safety Index Report – 2002] FY 02: 62% LBNL DOE-Recordable cases caused by poor ergonomics (Strains/Sprains, CTDs & RSIs). FY 02: LBNL Property Management dBase inventoried > 9,400 computers (desktops and laptops) issued to employees. 7/99-8/02: 20% LBNL employee visits (168) to Health Services triggered by computer use. 4/85-6/02: 145 WComp “ergo claims” resulting > $2M incurred costs and 13,602 days of TD/Loss Work Days (productivity).

4. ASEP Ergonomic support development Fall 2002 Phase I Concepts External support systems Device absorbs or applies forces to the anatomy externally. The effective dynamic is to provide a lifting force, or net decrease in gravity, applied to selected parts of the arm-shoulder system. Reactions and redistributed forces are routed to the chair, or floor. Body supported systems Device reroutes forces from one part of the anatomy to another. The effective dynamic is to augment or unload muscle groups that ordinarily take constant strain, and reroute forces onto other parts of the anatomy, into the chair, or into the floor.
