Abstract

Computers have started to occupy a greaterplace in our lives with the development of technology and communication systems. Increasingly, longer hours are spent sitting at the computer at bothwork and home. Sitting in a fixed position forhours, not giving any break, bad posture, repeatingmotions and work appliances which are not ergonomical, added up with individual factors such asage and sex and psychosocial and work-relatedproblems, result in increasing rates of musculoskeletal complaints in computer users. As a result, decrease in efficiency, increase in absenteeism andhealth expenditures have revealed the necessity forergonomical applications aimed at decreasing riskfactors. It is possible to prevent or decrease themusculoskeletal complaints frequently observed in computer users with simple methods such as teaching correct working positions, ergonomic trainings, exercises that can be easily done during rest breaks and ergonomical arrangement of the workplace. In this review, the aim is to discuss under the framework of the literature the frequency of occupational musculoskeletal complaints OMSC in computer users and the risk factors and to review the available information on work appliances, work posture, their ergonomical features for protection from these risk factors.

Abstract

Özet Teknoloji ve iletişim sistemlerinin gelişmesi ile bilgisayarlar yaşamımızda daha fazla yer almış, hem işte, hem de evde bilgisayarlar başında giderek daha uzun saatler geçirilmeye başlanmıştır. Saatler boyunca sabit pozisyonda bilgisayar ile çalışanlarda üst ekstremite boyun ve sırt yakınmalarının oranlarının arttığı da gözlenmiştir. Çalışma süreleri, ara verme, kötü postür, tekrarlayan hareketler, çalışma araçlarının ergonomik olmaması, kişisel ve psikososyal faktörler kas iskelet yakınmaları ile ilişkili midir? Bilgisayar kullananlarda sık görülen kas iskelet yakınmaları doğru çalışma duruşlarının öğretilmesi, ergonomi eğitimleri, dinlenme aralarında kolayca yapılabilecek egzersizler ve işyeri ortamının ergonomik düzenlenmesi gibi basit yöntemlerle önlenebilir mi? Bu derlemede amaç; bilgisayar kullananlarda MKİY sıklığı ve risk faktörlerini literatür çerçevesinde tartışmak ve bu risk faktörlerinden korunmak için, çalışma ortamı, araçları, çalışma postürü ve aralarda yapılacak egzersizler hakkında bilgileri gözden geçirmektir. Anahtar Sözcükler: bilgisayar kullananlar, mesleki kas-iskeletrahatsızlıkları, ergonomi.
