Computer-related posture and musculoskeletal discomfort in schoolchildren

The aim of the study was to investigate the posture and musculoskeletal discomfort of secondary school students while working at computers in school. Students (n = 40) were observed while working at a computer during their designated computer class. The Rapid Upper Limb Assessment Tool (RULA) was used to assess posture. A Body Discomfort Chart (BDC) and Visual Analogue Scale (VAS) were used to record the area(s) and intensity of musculoskeletal discomfort, if any, experienced by the students at the beginning and end of the computer class. None of the students’ posture was in the acceptable range (Action Level 1) according to RULA. The majority (65%) were in Action Level 2, 38% were in Action Level 3, and 5% were in Action Level 4. Poor working postures were associated with reported discomfort in the spine and shoulder areas. Secondary schoolchildren demonstrated poor working posture and had musculoskeletal discomfort during computer use. RULA proved to be, in general, a suitable method for the evaluation of students’ posture. RULA scores corresponded well with reported discomfort, indicating that poor posture in a particular area is associated with discomfort in that area.
