As use of the visual display terminal(VDT) is becoming more generalized as a result of office automation, the so-called 'VDT syndrome' which is often observed with the workers using VDT has emerged as a serious occupational health problem. However, few comparative study with control group using not only subjective symptom but also physical examination has been conducted. We have conducted a study comparing prevalence rated of musculoskeletal disorder between 113 VDT operators of a telecommunication company and the control groups of housewives and office ladies through a review of subjective symptoms as well as physical examination by physiatrist to understand the magnitude of problem and relative risk of VDT worker. The symptom rates of upper extremity disability in VDT operators were higher than those of controls especially in neck and shoulder area. Fifty-four(47.8%) of 113 VDT operators met our case definition of upper extremity disorder by subjective symptom and physical examination. Myofascial pain syndrome of neck and shoulder muscles were the most common(46.9%). The odd ratio of using VDT operation for developing myofascial pain syndrome in the neck or shoulder area were 2.52(compared to controls of office ladies) and 2.64(compared to controls of housewives). Other anatomical lesion such as elbow, hand and wrist shows slight higher prevalence rates of musculoskeletal disorder than control groups but not statistically significant.

We filmed throwing motion of 16 Korean professional elite pitchers and analyzed them three dimensionally, especially about kinematic parameters. We summarized the data and compared them with American major league pitchers. We concluded that the Korean professional pitchers had similar joint angle on each pitching point except more front knee flexion, less shoulder ext, rotation and less elbow flexion on maximal cocking point and more shoulder abduction on ball release point than American major league pitchers, which can interpreted as less stored energy to accelerate the ball and higher risk of supraspinatus impingement. And the Korean professional baseball pitchers had generally lower angular velocities of joints or body segments than American major league pitchers especially pelvis and upper trunk rotation in horizontal plane and shoulder internal rotation in sagittal plane, which may suggest lower pitching ability.
