Brief summary (from the registry)
Computer settings points to a number of risk factors which may induce the development of Work related MSD (WRMSD). In light of the expanded use of computers and the increased occurrence of Upper Extremity (UE) WRMSD among computer operators various intervention programs have been developed and tested. Nevertheless, many of these programs do not meet the criteria of quality and level of evidence. The main objective of this study is to use simultaneously a three dimensional (3D) kinematic analysis system, surface electromyography (SEMG) and fingertip force measurement system (Flexiforce) while typing, to test the efficacy of primary and secondary preventive intervention programs aimed at reducing MSD among computer operators. Work hypothesis: Significant score differences will be found on the evaluation parameters between the research group which underwent ergonomic training with biofeedback, the group without feedback, and the control group.The evaluated parameters will correlate with the appearance of MSD symptoms and pain and will affect level of function. The study will include 66 participants, programmers and computer engineers. The participants will be assigned randomly to one of three groups: 1) participants will receive ergonomic training with biofeedback; 2) participants will receive ergonomic training without biofeedback; and 3) control group, without intervention. Each group will consist of 22 participants. Treatment efficacy will be tested both at work and in the motion lab. In the lab, 3D kinematic measurements and fingertip forces relevant to typing while entering a standard text will be measured. At the work site, anthropometric and measurements, work station measurements, posture observation and questionnaires about, psychosocial status, function and pain level will be filled The preventive program will be performed at the workstation after the preliminary data collection phase. The program will consist of one group meeting at the workplace for all emp…
