Characterization of posture and comfort in laptop users in non-desk settings
چکیده انگلیسی

Laptop computers may be used in a variety of postures not coupled to the office workstation. Using passive motion analysis, this study examined mean joint angles during a short typing/editing task in college students (n = 20), in up to seven positions. Comfort was assessed after task execution through a body map. For three required postures, joint angles in a prone posture were different than those while seated at a couch with feet either on floor or on ottoman. Specifically, the prone posture was characterized by comparatively non-neutral shoulders, elbows and wrists, and pronounced neck extension. Significantly greater intensity and more regions of discomfort were marked for the prone posture than for the seated postures. It is recommended that the prone posture only be assumed briefly during laptop use. Exposure to laptops outside of the office setting should be assessed in future epidemiologic studies of musculoskeletal complaints and computer use.


► We examine mean joint angles and comfort in laptop usage in non-desk settings.
► Seated positions are typified by flexed neck, neutral shoulders and elbows.
► A prone position showed neck extension and non-neutral shoulders, elbows, and wrists.
► The prone posture elicited significantly greater discomfort intensity.
