The hand is used in nearly all physical work activities and is the recipient of more work injuries than any other part of the body except the trunk. In 1983 there were 360,000 disabling injuries to the hand and fingers (Accident Facts, 1984) . Accident statistics in some industries suggest that cumulative hand trauma disorders (CHTD) result in up to 50 percent of the total hand injuries as listed in Table 1.1.
