The Harrington study of DataHand pain reduction experience was independently conducted by Janet S. Kaiser and James B. Koeneman, Ph.D., in conjunction with the Harrington Arthritis
Research Center, an internationally recognized research center which has conducted research for NASA and Fortune 500 clients. This study was funded by an unrestricted research grant
from DataHand Systems, Inc. All data acquisition and analysis was done independently by the researchers.
The Harrington study was peer reviewed and published by the Rehabilitative Engineering Society of North America. The
study was presented at the society's North American conference held June 17-22, 1994.
No medical claims are made by DataHand Systems, Inc. on behalf of the DataHand ergonomic keyboard; pain reduction is
accomplished by addressing all the flat keyboard design issues which are associated with musculoskeletal stress. With keyforces and finger movement reduced substantially and hand
movement eliminated, the sources of much keyboard-related stress are eluded. As a result, pain subsides over a period of time.
