Purpose: This study was planned to investigate the inter/intra observer reliability of the Ovako Working Posture Analysis System (OWAS) and to evaluate the body postures of senior physiotherapy students during intervention with the OWAS method in terms of ergonomic risk.
Method: To evaluate the postures during the study, digital photographs of 60 students were taken from three different perspectives: front, back, and side. The photographs were manually scored by three physiotherapists using the OWAS method. In the first stage, the inter/intra-observer reliability of the OWAS method was examined, and in the second stage, ergonomic risk analysis was performed on the OWAS total score.
Results: The study included 49 female and 11 male physiotherapy and rehabilitation senior students with a mean age of 22.45±1.09 (21-26). Inter/intra observer reliability was found to be good (ICCIrO=0.815; ICCIaO=0.872; p<0.05). Twenty-nine students (48.3%) were classified as "No action required", twenty-five students (41.7%) as "Corrective actions required in the near future", two students (3.3%) as "Corrective actions required as soon as possible" and four students (6.7%) as "Corrective actions are required immediately".
Conclusion: In the study; the OWAS method was found to be inter/intra observer reliable. It was determined that more than half of physiotherapy and rehabilitation students were at risk of developing work-related musculoskeletal problems. It is predicted that work-related musculoskeletal problems in physiotherapists can be reduced by early detection of these risks.

Ovako çalışma postürü analiz sisteminin gözlemciler arası ve içi güvenirliği: son sınıf fizyoterapi ve rehabilitasyon öğrencilerinde çalışma postürü analizi

Öz

Amaç: Bu çalışma, Ovako Çalışma Postürü Analiz Sistemi'nin (OWAS) gözlemciler arası/içi güvenilirliğini araştırmak ve son sınıf fizyoterapi ve rehabilitasyon öğrencilerinin müdahale sırasındaki vücut duruşlarını OWAS yöntemi ile ergonomik risk açısından değerlendirmek amacıyla planlandı.
Yöntem: Çalışma sırasında ki duruşlarını değerlendirmek için 60 öğrencinin dijital fotoğrafları önden, arkadan ve yandan olmak üzere üç farklı düzlemden çekildi. Fotoğraflar üç fizyoterapist tarafından OWAS yöntemi kullanılarak manuel olarak puanlandı. İlk aşamada OWAS yönteminin gözlemciler arası/içi güvenilirliği incelendi, ikinci aşamada ise OWAS toplam puanı üzerinden ergonomik risk analizi yapıldı.
Bulgular: Çalışmaya, yaş ortalaması 22,45±1,09 (21-26) olan 49 kız ve 11 erkek fizyoterapi ve rehabilitasyon son sınıf öğrencisi katıldı. Gözlemciler arası/içi güvenirlik iyi bulundu (ICCGA=0,815; ICCGİ=0,872; p<0,05). Yirmi dokuz öğrenci (%48,3) “İyileştirme gerekli değil”, yirmi beş öğrenci (%41,7) “Yakın gelecekte iyileştirme gerekli”, iki öğrenci (%3,3) “İyileştirmeler mümkün olan en kısa sürede gerekli” ve dört öğrenci (%6,7) “İyileştirmeleri şimdi uygula” olarak sınıflandırıldı.
Sonuç: Çalışmada; OWAS yönteminin gözlemciler arası/içi geçerli olduğu bulundu. Fizyoterapi ve rehabilitasyon öğrencilerinin yarısından fazlasının işle ilgili kas-iskelet sistemi sorunları geliştirme riski altında olduğu belirlendi. Bu risklerin erken tespit edilmesi ile fizyoterapistlerde işle ilgili kas-iskelet sorunlarının azaltılabileceği öngörülmektedir.
