HONG KONG, April 23 (Xinhuanet) -- Prolonged use of computer and incorrect postures can lead to hand disorder, researchers from the University of Hong Kong Faculty of Medicine said on Saturday at the second international forum on occupational diseases.

    The latest studies on occupational hand problems by the medical faculty showed that non-physical work in the offices can also lead to occupational hand disorder, though serious hand injuries occur frequently in physical-related industries, such as construction.

    Researchers said many office jobs require prolonged use of computer. Incorrect sitting postures and repetitive work may lead to disorders in hands and wrists, or called Carpal Tunnel Syndrome(CTS). It is estimated that there are about 4,000-6,000 new CTS cases in Hong Kong annually.

    The research findings revealed that when conducting daily activities, frequent flexion would increase the risk of CTS by 4 times and frequent extension and sustained force of the wrist would increase the risk of CTS by 2.5 times.

    The researchers hope the public would gradually realize the risks of occupational hand diseases through their studies and prevent repetitive stress injuries by taking correct postures and healthy lifestyle. Enditem
