OBJECTIVE. This study’s objective was to discover whether a difference exists in four postural angles while performing a typing task on a laptop and a desktop computer.
METHOD. Twenty healthy participants performed a 5-min typing task on each computer.
RESULTS. Statistically significant differences for all angles were found when comparing sitting at the desktop computer with sitting at the laptop. Neck angle (p < .0005), head tilt (p < .0005), and lumbar lordosis (p = .018) were significantly higher when using the laptop. The greatest posterior pelvic tilt was associated with the desktop (p = .018).
CONCLUSION. A desktop appears to be more appropriate for the cervical and lumbar regions; however, using a laptop may be more suitable for pelvic tilt.
