New industry reporting shows cumulative trauma injuries are attracting growing attention from insurers and regulators as a major driver of long-term workers’ compensation costs. Unlike single-incident claims, repetitive stress injuries often develop over extended periods, leading to longer claim duration, complex treatment and greater legal exposure. Analysts note that rising cumulative trauma trends are influencing underwriting decisions and could shape how carriers evaluate workplace risk moving forward. The shift places renewed emphasis on consistent job design, ergonomic awareness and proactive oversight that reduce exposure before claims escalate into extended liabilities.

“Cumulative trauma claims sit at the intersection of safety practices and system pressure,” said Jacob Sargent, director of public policy services for the Ohio Manufacturers’ Association. “When insurers start tightening around long-duration claims, employers feel it through underwriting, premiums and claim outcomes. Staying ahead of repetitive stress risks is not just a safety issue. It is a long-term competitiveness issue.” 2/25/2026
