BELLEVILLE, Ill. (AP) — A newspaper’s ongoing investigation has found an expert report, commissioned by the state of Illinois, showed that locking and unlocking prison cells didn’t cause repetitive trauma injuries in guards.

The Belleville News-Democrat reports Sunday that the state continued to grant workers’ compensation claims to guards despite the findings of the 2008 report.

The report was unsuccessfully used to challenge some claims brought by guards at Menard Correctional Center.

The newspaper obtained the 17-page report through a Freedom of Information Act request.

The Belleville News-Democrat previously has reported that Menard prison staff claimed nearly $10 million since January 2008 through workers’ comp, many for carpal tunnel syndrome from locking and unlocking doors.

Workers’ compensation overhaul passed by the Illinois Legislature last week limits payments for carpal tunnel syndrome.
