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.
The design of ergonomic rules that support healthy body posture can make computer workstations safer by reducing biomechanical risks.
Practitioners can educate clients about how to effectively use computer workstations to avoid the risk of MSD associated with poor workstation design.
Because frequent laptop users are subject to injury caused by poor posture, practitioners can provide training on proper posture and preventive programs that can enhance computer users’ health.
