Further, NAW stated that while ergonomic principles can be useful, they have not evolved to a point that a generalized approach could be applied to measure or implement them. No determination can be made whether symptoms are caused at work or outside the workplace. Any regulation from OSHA could not be based on clearly defined terms or accurate measures.

However, NAW commended the Department of Labor for examining the inconclusive arguments surrounding ergonomics and for not succumbing to political pressures to hastily promulgate a new rule.
